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.

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.

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.

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 [Dis­play: 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 volt­age.
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 out­puts behave according to their settings
Setting the end value (setting range 75…125%, default value = 100%)
Setting the zero point in relation to the previ­ously 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 (de­fault 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).

Setting the filter depth of the analog output when using frequencies as input value (setting range 1...15).
This function can only be configured using the membrane keyboard.
Setting the analog output value if the measuring range is fallen below (setting range 0.00…24.00 mA, or
0.00…12.00 V)
Setting the analog output value if the measuring range is exceeded (setting range 0.00…24.00 mA, or
0.00…12.00 V)
Setting the analog output value with wire break or an input signal that is not available (setting range 0.00…24.00 mA, or
0.00…12.00 V)
Saving. By pressing the key, the set parameters are saved.
By pressing the key, the setting mode is in­terrupted without saving the parameters set.
By pressing the -key, the current settings are overwritten by the default values. The parame­ters of the frequency input and analog input are unaffected.

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 bot­tom 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) Wire­break!
3. Short-circuit frequency <-> GND!
4. No input signal found within the wire-break
detection time set (l.br.time).

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".
