1.4 MANUAL OR AUTOMATIC CONTROL
The controller can be used in two modes:
Automatic mode - in which the output power is automatically adjusted to hold the temperature at the
required value. The controller normally operates in this mode.
Manual mode - in which the output is manually adjusted by the Operator. In this mode the ‘MAN’ light
will be on.
One other mode is available:
Remote setpoint - The setpoint is generated as an input signal from a master 2000 series controller. In
this mode the REM light is on.

1.6 SELECTING SETPOINT 1 OR SETPOINT 2
The instrument has the facility to select two setpoints. This may be useful, for example, where it is
required to switch control between two different setpoints or to control in a standby condition, thus
avoiding the necessity to change the setpoint manually each time.
To Select Setpoint 1 or Setpoint 2
This may be done in two ways:-
1. By an external switch or relay contact wired to a digital input
2. Through the front panel using the SP list

1.7 RAMP DWELL FUNCTION
The ramp dwell function is selected by turning the setpoint rate limit parameter SPrr to a value. It can
be set to RUN in two ways:-
1. Through the front panel using the SP list
2. By an external switch or relay contact wired to a digital input configured for reset (rset). When
closed the program will reset. When open the program will run. To run the program from the initial
reset state, it is necessary to first close the switch then open it.
The controller will then ramp from setpoint 1 to setpoint 2 at a rate set by the SPrr parameter.
When the controller reaches setpoint 2 it can remain at this level for a timed period, using the dwel
parameter.
At the end of the dwell period the action of the controller is determined by the End Type parameter
End.t.
1.7.1 To Set up a Ramp/Time Program
Set setpoint 1 to the value at which to start the ramp. Set setpoint 2 to the value which you wish to ramp
to. This is described in the previous section.
Now press until SPrr is displayed

1.7.2 To Run the Program
In Full access level the Status of the program can be read as follows:-
A program may also be reset or run using an external switch contact if a digital input has been configured.
See Configuration section.
Figure 1-13 To Run the Ramp/Dwell Program
1.7.3 Power Failure During Program Run
1. During Ramp. After return of power, the working setpoint will servo to the current PV value, and
the ramp continues to SP2 followed by the timed dwell.
2. During Dwell. After return of power the working setpoint will servo to PV, the ramp continues to
SP2 followed by full programmed dwell. In effect this causes the program to restart.
☺ Use the Hide, Reveal and Promote features to customise the display for a programmer. See Chapter

1.11 ALARMS
Alarms are used to alert an operator when a pre-set level has been exceeded. They are normally used to
switch an output (see 1.12) – usually a relay – to provide external actions to the process.
Soft Alarms are indication only and do not operate an output.
Events are generally defined as conditions, which occur as part of the operation of the plant. They do not
require operator intervention and, therefore, do not cause an alarm message to be displayed. They can be
attached to operate an output (relay) in the same way as an alarm.
1.11.1 Types of Alarm Used in the 2200

Operation Installation and Operation Handbook
Hysteresis is the difference between the point at which the alarm switches ON and the point at which it
switches OFF.
It is used to prevent relay chatter.
Blocking Alarms only occur after the start up phase when the alarm has first entered a safe state. The
alarm is only indicated the next time it is active. It is used, for example, to ignore start up conditions
which are not representative of running conditions.
Latching Alarms see 7.1.1.
Loop Break Alarm. The control loop is considered to be open if the output demand signal increases to
saturation level but the error does not reduce after a set period of time. The time period can be set
manually, depending on the response time of the loop, using the parameter Lbt in the Alarm List (section
1.10.2). It is, also set automatically, following an autotune (see chapter 4), to 3 x Ti (integral time). The
time period, Lbt, starts from the point at which the output demand reaches saturation. The loop break
alarm L.br is displayed (as a diagnostic alarm, see section 1.12.3.) at the end of this period.
1.12 ALARM RELAY OUTPUT
☺ Alarms can operate a specific output (usually a relay). Any individual alarm can operate an
individual relay or any combination of alarms can operate an individual relay. They are either
supplied pre-configured in accordance with the ordering code or set up in configuration level.
See Chapter 5 for further information.

1.12.2 ALARM INDICATION AND ACKNOWLEDGEMENT
When an alarm occurs, the alarm mnemonic (e.g. 1FSH) will be indicated by a double flash in the HOME
display. Similarly, if more than one alarm occurs the relevant mnemonics are flashed in the HOME
display. The double flash will continue whilst the alarm condition is present and is not acknowledged.
Press and together to acknowledge the alarm.
If the alarm condition is still present when the alarm is acknowledged, it will be indicated by a single flash
of the alarm mnemonic and this single flash will be repeated for as long as the alarm condition remains.
When the alarm condition disappears the indication will also disappear..
If the alarm condition is no longer present when the alarm is acknowledged, the flashing message will
disappear immediately on acknowledgement.
If a relay has been attached to the alarm output (see Chapter 7 ‘Alarm Operation’), it will operate when the
alarm condition occurs and remain in the operated condition until the alarm is acknowledged AND it is no
longer present

2.2 INTRODUCTION
The Models 2208e and 2204e are precision temperature controllers with self tuning. They have a modular
hardware construction which provides two control outputs, two alarm relays and one communications
port. Two logic inputs are provided as standard.
2.2.1 Controller labels
The labels on the sides of the controller identify the ordering code, the serial number, and the wiring
connections.
Appendix A, Understanding the Ordering Code explains the hardware and software configuration of your
particular controller.
2.3 MECHANICAL INSTALLATION
To install the controller
1. Cut the panel to the relevant hole size shown in Figure 2-3 and 2.4.
2. Insert the controller through the front of this cutout.
3. Spring the upper and lower panel retaining clips into place. Secure the controller in position by
holding it level and pushing both retaining clips forward.
Note: If the panel retaining clips subsequently need removing, they can be unhooked from the side with
either your fingers or a screwdriver.
2.3.1 Unplugging and plugging-in the controller
The controller can be unplugged from its sleeve by easing the latching ears outwards and pulling it
forward out of the sleeve. When plugging the controller back into its sleeve, ensure that the latching ears
click into place to maintain moisture sealing protection.

2.4 WIRING
Please read Appendix B, Safety and EMC information before proceeding.
WARNING
! Please ensure that the controller is correctly configured for your application.
Incorrect configuration could result in damage to the process being controlled, and/or
personal injury. The controller may either have been configured when ordered, or may
need configuring now. See Chapter 5, Configuration.
The wiring connections are shown in figure 2-5. Outputs 1 and 2 are factory fitted modules which can be
any one of the types shown in figure 2-8. Check the ordering code on the controller side label to
determine which have been fitted.

2.4.1 Wire Sizes
All electrical connections are made to the screw terminals at the rear of the controller. They accept wire
sizes from 0.5 to 1.5 mm2 (16 to 22 AWG), and are protected by a hinged cover to prevent hands or metal
making accidental contact with live wires. Rear terminals should be tightened to a torque of 0.4Nm (3.5
lb in).
2.4.2 Wiring connections
The wiring connections are shown in figure 2-6. Outputs 1 and 2 are factory fitted modules which can be
any one of the types shown in figure 2-8. Check the ordering code on the controller side label to

PDS is a proprietary technique developed for bi-directional communication over a single pair of wires.
There are several operating modes.
In SSRx Load Doctor™ a logic output delivers a power demand signal to a TE10 solid state (SSR) relay
and the SSR responds with a single load circuit failure message.
In SSRx Enhanced Load Doctor™ a logic output delivers a power demand signal to an SSR and the SSR
responds with the ON state rms load current, and two fault messages - SSR failure or heater circuit failure.
2.6 SNUBBERS
The controller is supplied with ‘snubbers’ (15nF +100Ω) which should be wired across the relay or triac
outputs when switching inductive loads such as mechanical contactors and solenoid valves. The snubbers
are used to prolong contact life and to suppress interference when switching such loads. Snubbers pass
0.6mA at 110Vac and 1.2mA at 240Vac, which may be sufficient to hold in high impedance relay coils.
They should not, therefore, be used in such installations.
WARNING
When a relay contact is used in an alarm circuit ensure that the current passing through
the snubber when the relay contact is open does not hold in low power electrical loads and
thereby interfere with the failsafe operation of the alarm circuit.

Standard EIA-485 is a 2-wire connection which allows up to 32
controllers to be multi-dropped from a single communications link
over a distance of up to 1.2Km. To ensure reliable operation of the
communications link, (without data corruption due to noise or line
reflections) the connections between the controller should be made
using a twisted pair of wires inside a shielded cable with the
connections terminated with resistors in the manner shown in this

3.3 Edit level
Edit level is used to set which parameters you can see and adjust in Operator level. It also gives access to
the ‘Promote’ feature which allows you to select and add (‘Promote’) up to twelve parameters into the
Home display list, thereby giving simple access to commonly used parameters.
Setting operator access to a parameter
First you must select Edit level, as shown on the previous page.
Once in Edit level you select a list or a parameter within a list in the same way as you would in Operator
or Full level. Τhat is, you move from list header to list header by pressing the Page button, and from
parameter to parameter within each list using the Scroll button. However, in Edit level what is displayed
is not the value of a selected parameter but a code representing the parameter’s availability in
Operator level.
When you have selected the required parameter, use the and buttons to set its availability in
operator level.
There are four codes:
ALtr Makes a parameter alterable in Operator level
Pro Promotes a parameter into the Home display list
rEAd Makes a parameter or list header read-only (it can be viewed but not altered)
HidE Hides a parameter or list header.
For example:
3.3.1 Hiding or revealing a complete list
To hide a complete list of parameters, all you have to do is hide the list header. If a list header is selected
only two selections are available: rEAd and HidE.
(It is not possible to hide the ‘ACCS’ list which will always display the code: ‘LiSt’.)
3.3.2 Promoting a parameter
Scroll through the lists to the required parameter and choose the ‘Pro’ code. The parameter is then
automatically added (promoted) into the Home display list (the parameter will also be accessible as
normal from the standard lists. a maximum of 12 parameters can be promoted. Promoted parameters are
automatically ‘alterable’.
The parameter selected is the set point for Alarm 2 -

Installation and Operation Handbook Tuning
2208e and 2204e Controller 4-1
4. Chapter 4 TUNING
Before tuning please read Chapter 1, Operation, to learn how to select and change a parameter.
This chapter has three main topics:
• WHAT IS TUNING?
• AUTOMATIC TUNING
• MANUAL TUNING
4.1 WHAT IS TUNING?
In tuning you match the characteristics of the controller to that of the process being controlled in order to
obtain good control. Good control means:
Stable ‘straight-line’ control of the temperature at setpoint without fluctuation
Acceptable overshoot or undershoot of the temperature setpoint
Quick response to deviations from the setpoint caused by external disturbances, thereby restoring the
temperature rapidly to the setpoint value.
Tuning involves calculating and setting the value of the parameters listed in Table 4-1. These parameters
appear in the PiD list.
Parameter
Code
Meaning or Function
Proportional
band
Pb The bandwidth in display units over which the output power is
proportioned between minimum and maximum.
Integral time ti Determines the time taken by the controller to remove steady-state error
signals.
Derivative time td Determines how strongly the controller will react to the rate-of-change of
the measured value.
Low cutback Lcb The number of display units below setpoint at which the controller will
cutback the output power in order to prevent overshoot on heat up.
High Cutback Hcb The number of display units above setpoint at which the controller will
increase the output power in order to prevent undershoot on cool down.
Relative cool
gain
rEL.C Only present if cooling has been configured. Sets the cooling proportional
band by dividing the Pb value by the rEL.C value.
Table 4-1 Tuning parameters
4-2 2208e and 2204e Controller
Tuning Installation and Operation Handbook
4.2 AUTOMATIC TUNING
This method automatically determines the value of the parameters listed in table 4-1 on the previous page.
The 2208e and 2204e use a ‘one-shot’ tuner which works by switching the output on and off to induce an
oscillation in the measured value. From the amplitude and period of the oscillation, it calculates the
tuning parameter values.
If the process cannot tolerate full heating or cooling being applied during tuning, then the level of heating
or cooling can be restricted by setting the heating and cooling power limits in the Output list. However,
the measured value must oscillate to some degree for the tuner to be able to calculate values
A One-shot Tune can be performed at any time but normally it is performed only once during the initial
commissioning of the process. However, if the process under control subsequently becomes unstable
(because its characteristics have changed), you can re-tune again for the new conditions.
It is best to start tuning with the process at ambient temperature. This allows the tuner to calculate more
accurately the low cutback and high cutback values that restrict the amount of overshoot or undershoot.
4.2.1 Heating and Cooling Output Cycle Times
Before commencing a tuning cycle, set the values of CYC.H (heat cycle time) and CYC.C (cool cycle time)
in the op (output list). These values apply if you are using a logic, relay or triac output. They have no
effect on a DC output.
A logic output switching a solid state relay can be set to values such as 1 sec.
A relay or triac output should be set to 20 sec.
4.3 How to Tune
1. Set the setpoint to the value at which you will normally operate the process.
2. In the ‘Atun’ list, select ‘tunE’ and set it to ‘on’
3. Press the Page and Scroll buttons together to return to the Home display. The display will flash
‘tunE’ to indicate that tuning is in progress.
4. The controller will induce an oscillation in the temperature by turning the heating on and then off.
The first cycle will not complete until the measured value has reached the required setpoint.
5. After two cycles of oscillation the tuning will be completed and the tuner will switch itself off.
6. The controller will then calculate the tuning parameters listed in Table 4-1 and will resume normal
control action.
If you want ‘Proportional only’ or ‘PD’ or ‘PI’ control, you should set the ‘ti’ or ‘td’ parameters to
OFF before commencing the tuning cycle. The tuner will leave them off and will not calculate a value for
them.
For valve position tuning and set-up, please refer to Chapter 8.
Installation and Operation Handbook Tuning
2208e and 2204e Controller 4-3
4.3.1 Typical automatic tuning cycle
4.3.2 Calculation of the cutback values
Low cutback and High cutback are values that restrict the amount of overshoot or undershoot that occur
during large step changes in temperature (for example, under startup conditions).
If either low cutback or high cutback is set to ‘Auto’ the values will be fixed at three times the
proportional band, and will not be changed during automatic tuning.

Tuning Installation and Operation Handbook
4.4 MANUAL TUNING
If for any reason automatic tuning gives unsatisfactory results, you can tune the controller manually.
There are a number of standard methods for manual tuning. The one described here is the Ziegler-Nichols
method.
With the process at its normal running temperature:
1. Set the Integral Time ‘ti and the Derivative Time ‘td’ to OFF.
2. Set High Cutback and Low Cutback, ‘Hcb’ and ‘Lcb’, to ‘Auto’
3. Ignore the fact that the temperature may not settle precisely at the setpoint
4. If the temperature is stable, reduce the proportional band ‘Pb’ so that the temperature just starts to
oscillate. If the temperature is already oscillating, increase the proportional band until it just stops
oscillating. Allow enough time between each adjustment for the loop to stabilise. Make a note of the
proportional band value ‘B’ and the period of oscillation ‘T’.
5. Set the Pb, ti, td parameter values according to the calculations given in Table 4-2.

4.4.1 Setting the cutback values
The above procedure sets up the parameters for optimum steady state control. If unacceptable levels of
overshoot or undershoot occur during start-up or for large step changes in temperature, then manually set
the cutback parameters Lcb and Hcb.
Proceed as follows:
1. Set the low and high cutback values to three proportional bandwidths (that is to say, Lcb = Hcb = 3
x Pb).
2. Note the level of overshoot or undershoot that occurs for large temperature changes (see the
diagrams below).
In example (a) increase Lcb by the overshoot value. In example (b) reduce Lcb by the undershoot value.

Tuning Installation and Operation Handbook
4.4.2 Integrating action and manual reset
In a full three-term controller (that is, a PID controller), the integral term ‘ti’ automatically removes steady
state errors from the setpoint. If the controller is set up to work in two-term mode (that is, PD mode), the
integral term will be set to OFF. Under these conditions the measured value may not settle precisely at
setpoint. When the integral term is set to OFF the parameter manual reset (code rES) appears in the
PiD LisT in ‘FuLL’ Access level. This parameter represents the value of the power output that will
be delivered when the error is zero. You may set this value manually in order to remove the steady state
error.
4.4.3 Automatic droop compensation (Adc)
The steady state error from the setpoint, which occurs when the integral term is set to OFF, is sometimes
referred to as ‘droop’. Adc automatically calculates the manual reset value in order to remove this
droop. To use this facility, you must first allow the temperature to stabilise. Then, in the autotune
parameter list, you must set Adc to ‘CALC’. The controller will then calculate a new value for manual
reset, and switch Adc to ‘mAn’.
Adc can be repeated as often as you require but between each adjustment you must allow time for the
temperature to stabilise.

6. Chapter 6 USER CALIBRATION
This chapter has five topics:
• WHAT IS THE PURPOSE OF USER CALIBRATION?
• USER CALIBRATION ENABLE
• SINGLE POINT CALIBRATION
• TWO POINT CALIBRATION
• CALIBRATION POINTS AND CALIBRATION OFFSETS
To understand how to select and change parameters in this chapter you will need to have read Chapter 2 -
Operation, Chapter 3- Access Levels and Chapter 5 - Configuration.
6.1 WHAT IS THE PURPOSE OF USER CALIBRATION?
The basic calibration of the controller is highly stable and set for life. User calibration allows you to offset
the ‘permanent’ factory calibration to either:
1. Calibrate the controller to your reference standards
2. Match the calibration of the controller to that of a particular transducer or sensor input
3. Calibrate the controller to suit the characteristics of a particular installation.
User calibration works by introducing zero and span offsets onto the factory set calibration. The factory
set calibration can always be retrieved.

6.2 USER CALIBRATION ENABLE
The User calibration facility must first be enabled in configuration level by setting the parameter ‘AdJ' in

6.3 SINGLE POINT CALIBRATION
Your controller is calibrated for life against known reference sources during manufacture. A calibration
offset is often used to allow the controller to compensate for sensor and other system errors. The normal
procedure is to set up the system under test against a known independent reference, as follows:
Set up the process to be calibrated such that the known reference displays the required value
(temperature).
Observe the reading on the controller. If it is different, proceed as follows:

To protect the calibration against unauthorised adjustment return to Operator level and make sure that the
calibration parameters are hidden. Parameters are hidden using the ‘Edit’ facility described in Chapter
3.
6.4 TWO POINT CALIBRATION
The previous section described how to perform a single point calibration which applies a fixed offset over
the full display range of the controller. A two-point calibration is used to calibrate the controller at two
points and apply a straight line between them. Any readings above or below the two calibration points
will be an extension of this straight line. For this reason it is best to calibrate with the two points as far
apart as possible.
Proceed as follows:
1. Decide upon the low and high points at which you wish to calibrate.
2. Perform a single point calibration at the low calibration point in the manner
described above
3. Set the process under calibration such that the known reference exhibits the required higher Process
Value (temperature) and allow to stabilize.
4. Press the Scroll button to obtain the high calibration point as shown in the
following diagrams.

the new, calibrated value. You can calibrate at any point over the entire display
range
This is a single point calibration which applies a fixed offset over the full

7. Chapter 7 ALARM CONFIGURATION
The 2200e series controllers are capable of very sophisticated alarm strategies and, although setting up of
alarms has already been covered in previous chapters, this section has been included to enable operators
and commissioning engineers to design their own strategies for optimum plant operation.
7.1 DEFINITION OF ALARMS AND EVENTS
See also section 1.11 for further information on Alarms.
Alarms are used to alert an operator when a pre-set level or condition has been exceeded. They are
normally used to switch an output - usually a relay - to provide interlocking of the machine or plant or
external audio or visual indication of the condition.
Soft Alarms are indication only within the controller and are not attached to an output (relay).
Events - can also be alarms - but are generally defined as conditions which occur as part of the normal
operation of the process. They do not generally require operator intervention.
Events are referred to as Digital Output Functions in the manual (see Table B, page 5-14).
For the purposes of the operation of this instrument alarms and events can be considered
the same.
7.1.1 Types Of Alarms
The use of alarms in the 2208e and 2204e controllers is extremely versatile.
Up to 4 alarms can be configured. Any combination of these 4 alarms can be attached to any one or more
outputs, or any number of the available “soft” alarms can be combined to operate a single output.
Note: In a three term controller at least one of these outputs is used to maintain the required
temperature of the process.
Outputs 1A and 2A Are plug in modules.
Normally used for control outputs, eg. Heat and Cool, but can be used
for alarm outputs.
Outputs AA and 3A Are fixed relays.
Normally used for alarms or events, but can be used as control
outputs.
10A Output 4A (2204e 0nly) Is a plug in 10 Amp relay output.
Normally used to switch heaters directly in control mode, but can be
used as an alarm output.
Note:- This option is not available on controllers after Jan-04
!
Alarm Configuration Installation and Operation Handbook
7-2 2208e and 2204e Controller
There are seven process alarm types listed below. Alarm Types are found in configuration mode under the
Alarm Config. List.
ALARMS
Full Scale High The PV exceeds a set high level
Full Scale Low The PV exceeds a set low level
Deviation Band The difference between PV & SP is outside a set band
Deviation High The difference between PV & SP is higher than a set level
Deviation Low The difference between PV & SP is lower than a set level
High Current The measured current returned from a PDS slave is higher than a set level.
See also Chapter 9.
Low Current The measured current returned from a PDS slave is lower than a set level. See
also Chapter 9.
Each alarm can be set to:
Latching Alarm is indicated until acknowledged
(Off, Auto, MAN)
Auto Acknowledge: (Ltch Auto)
If the alarm is acknowledged while the alarm condition is still present, it will
cause the alarm to reset as soon as the alarm
condition is removed.
Manual Acknowledge: ( Ltch mAn)
If the alarm is acknowledged while the alarm condition is
still present, it will be ignored. A further acknowledgement
is required when the alarm condition has been removed to
cause the alarm to reset.
Blocking Alarm occurs after it has been through a start up phase not in alarm
condition.
Sense Of Output Relay energised or de-energised in alarm condition. See also sections 1-12
and 7.4.
Soft Alarms Indication only and do not operate an output.
See also Section 1.11 for further information on alarm types.
Installation and Operation Handbook Alarm Configuration
2208e and 2204e Controller 7-3
7.2 DIGITAL OUTPUT FUNCTIONS
In addition there are nine “digital output functions” used as events or alarms depending upon the
requirements of the process under control:
Sensor Break The input is open circuit
Loop Break The controller does not measure a response to an
output change
Load Failure Used with PDS Mode 1 load failure. See also Chapter 9.
Manual Controller in manual mode
PV Out Of Range Process Variable too high or too low
Remote SP Fail No signal measured at the remote set point input terminals
Heater Fail Used with PDS Mode 2 heater open circuit. See also Chapter 9 .
SSR Fail Used with PDS Mode 2 solid state relay open or short circuit. See also Chapter 9
Program END Signals the end of a program
New Alarm Signals a new alarm
The Sense of the Output can be set to relay energised or de-energised in the alarm condition for
any of the above functions.

8. Chapter 8 MOTORISED VALVE CONTROL
8.1 PARAMETERS FOR MOTORISED VALVE CONTROL
The 2208e and 2204e can be configured for motorised valve control as an alternative to the
standard PID control algorithm. This algorithm is designed specifically for positioning
motorised valves.
The motorised valve algorithm operates in the boundless mode, which does not require a position
feedback potentiometer for control purposes.
The following parameter list will appear in the navigation diagram shown in Chapter 1 if your controller is
configured for motorised valve control.

Ont.H Output pulse minimum on time, in seconds. Auto 999.9 0.2
Table 8-1 Motorised valve parameter list
8.2 COMMISSIONING THE MOTORISED VALVE CONTROLLER
Proceed as follows:
1. Measure the time taken for the valve to be raised from its fully closed to its fully open position and
enter this as the value in seconds into the ‘mtr’ parameter.
2. Set all the other parameters to the default values shown in Table 8-1.
The controller can then be tuned using the automatic or manual tuning techniques.
8.2.1 Adjusting the minimum on-time ‘Ont.H’
The default value of 0.2 seconds is satisfactory for most processes. The minimum on time determines how
accurately the valve can be positioned. The shorter the time, the more precise the control. However, if
the time is set too short, process noise will cause an
excessively busy valve.

8.3.1 Auto Tuning
Before the auto tune is activated, the TD parameter must be set to a numeric value. The TD parameter
cannot be set to OFF when an auto tune is activated. When the auto tune is complete, the auto tune will
set the TD parameter back to the OFF position.

Installation and Operation Handbook Load Current Monitoring
2208e and 2204e Controller 9-1
9. Chapter 9 LOAD CURRENT MONITORING AND DIAGNOSTICS
9.1 Load Current Monitoring and Diagnostics
Current flowing in a system of electrical heating elements (the ‘Load’) can be displayed on the controller
by using a TE10 SSR fitted with intelligent current transformer, PDCTX, or an SSR or contactor with an
external PDCTX.
Load current monitoring and diagnostics may be used with any time proportioned output, fitted in module
position 1A, and uses the logic output wires which drive the SSR to return signals back to the controller
These signals represent the RMS value of the load current during the ON period, or load related alarm
conditions. It is not designed for analogue outputs i.e. phase angle control.
It is also designed for single phase operation only.
There are three modes of operation:-
1. Mode 1
This is used with TE10 SSR only. It detects if there is a break in the heater circuit. This includes heater
or SSR open circuit. A single Load Failure alarm message is displayed on the lower readout of the
controller.
2. Mode 2
This is used with TE10 SSR plus PD/CTX intelligent current transformer, and provides:-
Display of true RMS load current On the
lower readout of the controller
Displays the true RMS current in the ON state to
the load.
Low current alarm Analogous to Partial
Load Failure (PLF) supplied in some SSRs
Provides advanced warning of failure of one or
more heaters in parallel
High current alarm Activated when the
heater exceeds a set limit
Typically used where element bunching may occur
SSR short circuit This will apply full power to the heaters which
could result in an over temperature condition. This
alarm provides early warning.
Heater failure Indicates open circuit load conditions
3. Mode 5
This mode is for use with contactors or other devices which do not use the PDS logic output from the
controller as the drive signal. For example, a time proportioning logic,relay or triac output. Mode 5,
therefore, requires an additional input to the controller to display the load conditions. It uses the digital
input terminals for this, as shown in Figure 9-2. Mode 5 provides the same features as mode 2 with two
additional alarms:-
Current Transformer Open Circuit An alarm is shown if the PDS connection to
PDCTX or SSR become disconnected
Current Transformer Short Circuit An alarm is shown if the PDS connection from
PDCTX or SSR are short circuited

9.10 The Scaling Factor
The value of the current displayed on the controller is scaled using the scaling factor. This is found in the
inSt ConF list. It is set, by default, to 100 and assumes a single turn through the current
transformer. If two turns are made through the current transformer it will be necessary to adjust the
scaling factor to 50 to obtain the same reading.
Under normal conditions you should not need to change the scaling factor.
If, however, you wish to change the sensitivity of the current reading, for example, to read very low
currents you may need to change the number of turns through the PDCTX and/or adjust the scaling factor
to compensate. See also note 1 below.

Installation and Operation Handbook Safety
2208e and 2204e Controller 12-1
12. Appendix B SAFETY and EMC INFORMATION
This controller is intended for industrial temperature and process control applications when it will meet
the requirements of the European Directives on Safety and EMC. Use in other applications, or failure to
observe the installation instructions of this handbook may impair safety or EMC. The installer must
ensure the safety and EMC of any particular installation.
Safety
This controller complies with the European Low Voltage Directive 73/23/EEC, amended by 93/68/EEC,
by the application of the safety standard EN 61010.
Electromagnetic compatibility
This controller conforms with the essential protection requirements of the EMC Directive 89/336/EEC,
amended by 93/68/EEC, by the application of a Technical Construction File. This instrument satisfies the
general requirements of the industrial environment defined in EN 50081-2 and EN 50082-2. For more
information on product compliance refer to the Technical Construction File.
GENERAL
The information contained in this manual is subject to change without notice. While every effort has been
made to ensure the accuracy of the information, your supplier shall not be held liable for errors contained
herein.
Unpacking and storage
The packaging should contain an instrument mounted in its sleeve, two mounting brackets for panel
installation and this operating book. Certain ranges are supplied with an input adapter.
If on receipt, the packaging or the instrument are damaged, do not install the product but contact your
supplier.
If the instrument is to be stored before use, protect from humidity and dust in an ambient temperature
range of -30oC to +75oC.
Service and repair
This controller has no user serviceable parts. Contact your supplier for repair.
Caution: Charged capacitors
Before removing an instrument from its sleeve, disconnect the supply and wait at least two minutes to
allow capacitors to discharge. It may be convenient to partially withdraw the
instrument from the sleeve, then pause before completing the removal. In any case, avoid touching the
exposed electronics of an instrument when withdrawing it from the sleeve. Failure to observe these
precautions may cause damage to components of the instrument or some discomfort to the user.
Electrostatic discharge precautions
When the controller is removed from its sleeve, some of the exposed electronic components are vulnerable
to damage by electrostatic discharge from someone handling the controller. To avoid this, before handling
the unplugged controller discharge yourself to ground.
Cleaning
Do not use water or water based products to clean labels or they will become illegible. Isopropyl alcohol
may be used to clean labels. A mild soap solution may be used to clean other exterior surfaces of the
product.
Safety Installation and Operation Handbook
12-2 2208e and 2204e Controller
Installation Safety Requirements
Safety Symbols
Various symbols are used on the instrument, they have the following meaning:
Caution, (refer to the
accompanying documents)
Functional earth
(ground) terminal
!
The functional earth connection is not required for safety purposes but is used to ground RFI filters.
Equipment protected throughout by DOUBLE
INSULATION
Personnel
Installation must only be carried out by qualified personnel.
Enclosure of live parts
To prevent hands or metal tools touching parts that may be electrically live, the controller must be
installed in an enclosure.
Caution: Live sensors
The logic and PDS outputs are electrically connected to the main PV input, (thermocouple etc.). If the
temperature sensor is connected directly to an electrical heating element then these non-isolated inputs
and outputs will also be live. The controller is designed to operate under these conditions. However you
must ensure that this will not damage other equipment connected to these inputs and outputs and that
service personnel do not touch connections to these I/O while they are live. With a live sensor, all cables,
connectors and switches for connecting the sensor and non-isolated inputs and outputs must be mains
rated.
Wiring
It is important to connect the controller in accordance with the wiring data given in this handbook. Take
particular care not to connect AC supplies to the low voltage sensor input or other low level inputs and
outputs. Only use copper conductors for connections, (except thermocouple). Ensure that the wiring of
installations comply with all local wiring regulations. For example in the UK, use the latest version of the
IEE wiring regulations, (BS7671). In the USA, use NEC Class 1 wiring methods.
Power Isolation
The installation must include a power isolating switch or circuit breaker that disconnects all current carrying
conductors. The device should be mounted in close proximity to the controller, within easy reach of the
operator and marked as the disconnecting device for the instrument.
Earth leakage current
Due to RFI Filtering there is an earth leakage current of less than 0.5mA. This may affect the design of an
installation of multiple controllers protected by Residual Current Device, (RCD) or Ground Fault
Detector, (GFD) type circuit breakers.
Installation and Operation Handbook Safety
2208e and 2204e Controller 12-3
Overcurrent protection
To protect the internal PCB tracking within the controller against excess currents, the AC power supply to
the controller and power outputs must be wired through the fuse or circuit breaker specified in the
technical specification.
Voltage rating
The maximum continuous voltage applied between any connection to ground must not exceed 264Vac.
The controller should not be wired to a three phase supply with an unearthed star connection. Under fault
conditions such a supply could rise above 264Vac with respect to ground and the product would not be
safe.
Voltage transients across the power supply connections, and between the power supply and ground, must
not exceed 2.5kV. Where occasional voltage transients over 2.5kV are expected or measured, the power
installation to both the instrument supply and load circuits should include a transient limiting device.
These units will typically include gas discharge tubes and metal oxide varistors that limit and control
voltage transients on the supply line due to lightning strikes or inductive load switching. Devices are
available in a range of energy ratings and should be selected to suit conditions at the installation.
Conductive pollution
Electrically conductive pollution must be excluded from the cabinet in which the controller is mounted. For
example, carbon dust is a form of electrically conductive pollution. To secure a suitable atmosphere, install an air
filter to the air intake of the cabinet. Where condensation is likely, for example at low temperatures, include a
thermostatically controlled heater in the cabinet.
Grounding of the temperature sensor shield
In some installations it is common practice to replace the temperature sensor while the controller is still
powered up. Under these conditions, as additional protection against electric shock, we recommend that
the shield of the temperature sensor is grounded. Do not rely on grounding through the framework of the
machine.
Over-temperature protection
When designing any control system it is essential to consider what will happen if any part of the system
should fail. In temperature control applications the primary danger is that the heating will remain
constantly on. Apart from spoiling the product, this could damage any process machinery being
controlled, or even cause a fire.
Reasons why the heating might remain constantly on include:
• the temperature sensor becoming detached from the process
• thermocouple wiring becoming short circuit;
• the controller failing with its heating output constantly on
• an external valve or contactor sticking in the heating condition
• the controller setpoint set too high.
Where damage or injury is possible, we recommend fitting a separate over-temperature protection unit,
with an independent temperature sensor, which will isolate the heating circuit.
Please note that the alarm relays within the controller will not give protection under all failure conditions.
Safety Installation and Operation Handbook
12-4 2208e and 2204e Controller
Installation requirements for EMC
To ensure compliance with the European EMC directive certain installation precautions are necessary as
follows:
• For general guidance refer to EMC Installation Guide, HA025464.
• When using relay or triac outputs it may be necessary to fit a filter suitable for suppressing the
conducted emissions. The filter requirements will depend on the type of load. For typical
applications we recommend Schaffner FN321 or FN612.
• If the unit is used in table top equipment which is plugged into a standard power socket, then it is
likely that compliance to the commercial and light industrial emissions standard is required. In this
case to meet the conducted emissions requirement, a suitable mains filter should be installed. We
recommend Schaffner types FN321 and FN612.
Routing of wires
To minimise the pick-up of electrical noise, the sensor input wiring should be routed away from high-
current power cables.
Where this is impractical, shielded cables should be used for the signal wiring. Where signal wiring is
carrying (or could carry, under fault conditions) hazardous voltages*, double insulation should be used.
* A full definition of ‘Hazardous’ voltages appears under ‘Hazardous Live’ in BS EN61010. Briefly,
under normal operating conditions Hazardous voltage levels are defined as >30V RMS (42.2V peak) or
>60V dc.

2208e and 2204e Controller 13-1
13. Supplement 2208 Instruments:
New Short Sleeve Design MkIII
This supplement applies to:-
2208
Controllers
Manufactured from Feb-03
The month and year of manufacture are shown
in the last two pairs of digits of the instrument
serial number.
From Feb-03 an improved design of 1/8 DIN short sleeve will be shipped with all new 2208 controllers.
Details
A new sealing gasket will be fitted onto the instrument bezel ‘A’. This gasket replaces the gasket which
was moulded into the front of the sleeve of all previous instruments.
The gasket previously moulded into the sleeve where it fits behind the panel is now supplied as a separate
item ‘B’.
Reasons for the Change
This change is to ensure that IP65 sealing is reliably achieved and less physical effort is required to insert
the instrument into the new sleeve.
Recommendations
1. An instrument delivered after Feb 03 should be used with the sleeve supplied
2. If the instrument is required to replace one already in use, the existing sleeve should also be
replaced
3. A new instrument can be fitted into an existing sleeve by carefully removing gasket ‘A’ but
IP65 sealing will not be maintained
4. An existing instrument can be fitted into a new sleeve but IP65 sealing will not be maintained
It is, however, possible to achieve IP65 sealing for 3 and 4 above. A gasket kit is available from
Eurotherm by quoting Part No SUB24/GAS2408.
Then:-
5. To fit a new instrument in an older sleeve carefully remove gasket ‘A’. Replace it with the
thinner (1.25mm) gasket from the kit
6. To fit an existing instrument into a new sleeve fit the thicker (1.6mm) gasket from the kit
between the instrument and the sleeve
The seal ‘B’ supplied as a separate item with a new instrument, should be placed over the sleeve prior to
mounting it through the panel cut out as shown below:-
