Data Sheet

1Description

MCR-f-UI-DC, the programmable MCR frequency

transducer, is a module for displaying and converting

frequencies up to120 kHz. On the input side, all common

frequency generator signals in 2, 3 and 4-wire technology,

and signals from incremental encoders can be collected.

The input impulses are evaluated using period

measurement and are then output by a processor as an

analog voltage or current value to match the measuring

range start and end value entered.

In order to achieve as short as possible reaction times, the

inputs of the frequency transducer have purposely been

designed without a frequency input filter. An automatic

measurement range selection function (autorange) ensures

that the measured value is always displayed with the

optimum resolution. Frequency interferences can, however,

lead to too large a division factor being selected for low input

frequencies. This in turn can result in an erratic output signal

(see "Operation with Disturbed Frequency Input Signals" on

page 6).

In order to stabilize fluctuating input values, a filter function

has been implemented for conversion into the analog output

value. The depth of this filter can be set from 1 to 15 using

the membrane keyboard. The optimum filter depth depends

on the application.

In addition to the analog output, there is also a PNP

transistor switching output with a maximum carrying

capacity of 100 mA, for monitoring functions, for example

(not short-circuit proof).

Specially for rotational speed measurement, it is possible to

both enter the measuring range start and end value in

revolutions per minute (RPM), and to observe the

revolutions in RPM on the LCD (4-pos. + RPM as unit) during

operation.

Make sure you always use the latest documentation.

Frequency Input Signals

7.1 Measures to Counter External Influences

– Use shielded conductors.

– Lay cables in an appropriate manner (EMC-compliant).

– Connect terminal 4 (GND 1) along the most direct route

to PE.

7.2 If Signal Level > 20 V

– Unplug the jumper located in the module after opening

the side flap. The jumper can be parked temporarily on

one of the three free pins.

– Now route the frequency input signal to the module via

terminal 2. The signal is returned via terminal 4

(GND 1).

– No additional settings are necessary.

7.3 If Signal Level > 10 V

– Connect the bottom two pins of the pin strip with the

jumper.

– Now route the frequency input signal to the module via

terminal 2.

– No additional settings are necessary.

8 Resetting to Delivery State

– Connect the top two pins of the pin strip (nearest

display) with the jumper.

– Terminal 2 is now ready again for the connection of

NAMUR sensors.

10 Functions of the Membrane

Keypad

Figure 4 Membrane keypad

Press the key briefly: The output value calcu-

lated is displayed.

By pressing the key again, you return to the cur-

rent input measured value.

Press the key briefly (< 0.sec.): Switches the

module to edit mode for frequency input sig-

nals.

Press the key for at least 2 seconds: Switches

the module to edit mode for analog input sig-

nals.

Press the keys briefly together (< 0.5 sec.):

Switches the module to extended edit mode

Press the keys briefly together: Ends edit

mode, without saving any settings that may

have been made.

Adopts the current setting in edit mode and

switches automatically to the next value.

10.1 Special Function of the Keys in Edit Mode

In edit mode for pulse input signals and for ana-

log input signals, pressing the enter key in

addition to the or key accelerates forward

or backward counting.

By releasing the key and then briefly pressing it

again, it is possible to carry out fine adjust-

ments.

11 Display on LCD

11.1 Display Within Setting Range

Frequency input for NAMUR, 2, 3 and 4-wire

sensors, incremental encoders with push-pull

and HTL output signal and dry contact. Settings

can be made in either Hz or RPM/kRPM [Dis-

play: kRM] / MRPM [Display: MRM].

Frequency input for NAMUR sensors with wire

break and short-circuit recognition. Settings

can be made in either Hz/kHz or RPM/kRPM

[Display: kRM] / MRPM [Display: MRM].

Current input 0…20 mA

Voltage input 0…10 V

ON delay of switching output.

(setting range 0…30 sec., default value = 0.00

sec.)

OFF delay of switching output.

(setting range 0…30 sec., default value = 0.00

sec.)

Setting POWER ON delay (switching output)

(setting range 0…30 sec., default value = 1.00

sec.) During this period, the switching output

does not react to events. This function is only of

effect directly after switching on the supply volt-

age.

Setting the wire-break detection time

(setting range 0.2…10.1 sec., default value =

10.1 sec.)

If no input signal is detected during this period,

"No Input" appears on the display and the out-

puts behave according to their settings

Setting the end value

(setting range 75…125%, default value =

100%)

Setting the zero point in relation to the previ-

ously set

output signal: (setting range -5…+5 mA / -

2.5…+2.5 V;

default value = 0 mA / 0 V)

Setting the division factor from 0.1 to 9999 (de-

fault value = 1.0). Slow positioning tasks require

holed coupling halves with multiple divisions

(factor > 1). Measuring the rotational speed of a

motor at the gearbox requires a small division

factor (factor < 1).

Saving. By pressing the key, the set

parameters are saved.

By pressing the key, the setting mode is in-

terrupted without saving the parameters set.

By pressing the -key, the current settings are

overwritten by the default values. The parame-

ters of the frequency input and analog input are

unaffected.

11.2 Displaying the Switching Output

If "High Setpoint" is exceeded, the transistor

switches to "High",

If "Low Setpoint" is fallen below, it switches to

"Low" (with hysteresis).

If"High Setpoint" is exceeded, the transistor

switches to "Low",

If "Low Setpoint" is fallen below, it switches to

"High" (with hysteresis)

If "High Setpoint" is fallen below, the transistor

switches to "High".

If "High Setpoint" is exceeded, the transistor

switches to "High".

Transistor is permanently switched (N/C).

Transistor is permanently switched off (N/O).

Between "Low Setpoint" and "High Setpoint",

the transistor switches to "High".

If "Low Setpoint" is fallen below, and

"High Setpoint" is exceeded, the transistor

switches to "High".

11.3 Messages in Operating Mode

Has fallen below the measuring range.

This message and the current frequency flash

alternately if the frequency falls below the bot-

tom measuring range set.

Measuring range exceeded.

This message and the current frequency flash

alternately if the frequency exceeds the top

measuring range set.

No input signal.

This message flashes for the following reasons:

1. No sensor connected!

2. For NAMUR: a) Short-circuit or b) Wire-

break!

3. Short-circuit frequency <-> GND!

4. No input signal found within the wire-break

detection time set (l.br.time).
