Be sure to observe the following precautions to prevent malfunction
or adverse affects on the performance or functionality of the product.
Not doing so may occasionally result in faulty operation. Do not
handle the Digital Temperature Controller in ways that exceed the
ratings.
1. This product is specifically designed for indoor use only.
Do not use this product in the following places:
•Places directly subject to heat radiated from heating equipment.
•Places subject to splashing liquid or oil atmosphere.
•Places subject to direct sunlight.
•Places subject to dust or corrosive gas (in particular, sulfide gas
and ammonia gas).
•Places subject to intense temperature change.
•Places subject to icing and condensation.
•Places subject to vibration and large shocks.
2. Use and store the product within the rated ambient temperature
and humidity.
Gang-mounting two or more Digital Temperature Controllers, or
mounting Digital Temperature Controllers above each other may
cause heat to build up inside the Digital Temperature Controllers,
which will shorten their service life. In such a case, use forced
cooling by fans or other means of air ventilation to cool down the
Digital Temperature Controllers.
3. To allow heat to escape, do not block the area around the Digital
Temperature Controller.
Do not block the ventilation holes on the Digital Temperature
Controller.
4. Be sure to wire properly with correct signal name and polarity of
terminals.
5. Use copper stranded or solid wires to connect bare wires.
Recommended Wire
Use the specified size of crimped terminals to wire the E5CC-800,
E5EC-800, E5AC-800, E5DC-800 (models with screw terminal
blocks) and E5CC-U-800 (plug-in models).
Recommended Crimped Terminal Size
For the E5@C-B-800 (Push-In Plus model), connect only one wire
to each terminal.
For other models, up to two wires of same size and type, or two
crimp terminals, can be inserted into a single terminal.
6. Do not wire the terminals that are not used.
7. Use a commercial power supply for the power supply voltage input
to a Digital Temperature Controller with AC input specifications.
Do not use the output from an inverter as the power supply.
Depending on the output characteristics of the inverter,
temperature increases in the Digital Temperature Controller may
cause smoke or fire damage even if the inverter has a specified
output frequency of 50/60 Hz.
8. To avoid inductive noise, keep the wiring for the product’s terminal
block away from power cables carry high voltages or large
currents. Also, do not wire power lines together with or parallel to
product wiring. Using shielded cables and using separate conduits
or ducts is recommended.
Attach a surge suppressor or noise filter to peripheral devices that
generate noise (in particular, motors, transformers, solenoids,
magnetic coils, or other equipment that have an inductance
component).
When a noise filter is used at the power supply, first check the
voltage or current, and attach the noise filter as close as possible
to the product.
Allow as much space as possible between the product and
devices that generate powerful high frequencies (high-frequency
welders, high-frequency sewing machines, etc.) or surge.
9. Use this product within the rated load and power supply.
10.Make sure that the rated voltage is attained within two seconds of
turning ON the power using a switch or relay contact. If the voltage
is applied gradually, the power may not be reset or output
malfunctions may occur.
11.Make sure that the Digital Temperature Controller has 30 minutes
or more to warm up after turning ON the power before starting
actual control operations to ensure the correct temperature
display.
12.When executing self-tuning for the E5DC-800, turn ON power to
the load (e.g., heater) at the same time as or before supplying
power to the product. If power is turned ON to the product before
turning ON power to the load, self-tuning will not be performed
properly and optimum control will not be achieved.
13.A switch or circuit breaker must be provided close to the product.
The switch or circuit breaker must be within easy reach of the
operator, and must be marked as a disconnecting means for this
unit.
14.Use a soft and dry cloth to clean the product carefully. Do not use
organic solvent, such as paint thinner, benzine or alcohol to clean
the product.
15.Design the system (e.g., control panel) considering the 2 seconds
of delay that the product's output to be set after power ON.
16.The output may turn OFF when you move to the initial setting level.
Take this into consideration when performing control operations.
17.The number of non-volatile memory write operations is limited.
Therefore, use RAM write mode when frequently overwriting data
during communications or other operations.
18.Always touch a grounded piece of metal before touching the
Digital Temperature Controller to discharge static electricity from
your body.
19.Use suitable tools when taking the Digital Temperature Controller
apart for disposal. Sharp parts inside the Digital Temperature
Controller may cause injury.
20.For compliance with Lloyd’s standards, the E5CC-800, E5CC-B-
800, E5CC-U-800, E5EC-800, E5EC-B-800, E5AC-800, and
E5DC-800 must be installed under the conditions that are
specified in Shipping Standards.
21.Do not touch the external power supply terminals or other metal
parts on the Digital Temperature Controller.
22.Do not exceed the communications distance that is given in the
specifications and use the specified communications cable. Refer
to the E5
@
C Digital Temperature Controllers User’s Manual (Cat.
No. H174) for information on the communications distances and
cables for the E5@C.
23.Do not bend the communications cables past their natural bending
radius. Do not pull on the communications cables.
24.Connectors may be damaged if they are inserted with excessive
force. When connecting a connector, always make sure that it is
oriented correctly. Do not force the connector if it does not connect
smoothly.
25.For the E5DC-800/E5DC-B-800, when you attach the Main Unit to
the Terminal Unit, make sure that the hooks on the Main Unit are
securely inserted into the Terminal Unit.
26.For the E5CC-U-800, when you attach the Main Unit to the socket,
make sure that the hooks on the socket are securely inserted into
the Main Unit.
27.Install the DIN Track vertically to the ground.
