Data Sheet
1 Description
The Standard Line digital display MCR-SL-D-FIT with six
displaying positions is used to display frequencies, pulses
and times. The required function can be configured quickly
and easily via the two front buttons.
Measured values can be easily read on the high-resolution
8 mm high LED display. The self-explanatory programma-
bility of the digital display offers the user enormous time-
savings.
The 24 V DC-supplied display in a 48 mm x 24 mm DIN for-
mat saves the data if the supply voltage fails. The position
of the decimal point is freely selectable. The digital display
also has a NPN transistor output that can be used, among
other things, for counting applications and is activated in the
"zero" position.
Features
– For frequencies, pulses and times
– Programmable
– Data saving with Power Off
– 6 positions displayed
– Display 48 x 24 mm
Make sure you always use the latest documentation.

5 Mounting
•Insert the digital display into the panel cut-out.
•Connect the inputs to the digital display (see "Terminal
Assignment" on page 3).
•Connect the power supply.
5.1 Mounting Frame
Figure 3 Mounting frame
Before carrying out any installation or mainte-
nance work, make sure that the power supply
of the digital display is switched off.
The digital display is not intended for use in ar-
eas with risks of explosion and in the branches
excluded by the standard EN 61010-1.
We recommend the use of wire end ferrules in
order to avoid short-circuits between adjacent
terminals.
The digital display shall not be installed near to
contactors or motor starters.
In order to keep the interferences at the mea-
suring input as low as possible, the signal and
power supply wires must be routed separately.
Use shielded cables for all signal/probe wirings
and avoid routing the signal/probe wirings par-
allel to each other. The shield shall only be
grounded at one point in order to avoid ground
loops.

6 Setting of the Operating
Parameters
• Hold down keys on front panel and switch on
supply voltage.
The display shows:
After releasing the keys the display alternates between
menu title and corresponding menu item with a fre-
quency of 0.5 Hz. After any key is pressed, only the
menu item is displayed.
•Pressing the right key, the menu item will be switched
to next value.
To input numerical values (e. g. for scaling factor), se-
lect first the decade with the left key. The decade
blinks. Set now the numerical value using the right key
•Hold down the left key and press the right key to switch
to the next menu title.
•After programming the last menu item, the program-
ming routine will be left (menu "EndPro") and the
new values will be stored by switching the menu item
to "YES". If you chose "NO", the programming routine
will be passed through once again.
