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

Make sure you always use the latest documentation.

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.

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.

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).
