I Front view with operating controls
a Indication of operational states with LEDs
U: green LED
- Status indication of control supply
voltage
F: red LED
- Fault message
R: yellow LED
- Status indication of the output relays
b Test / Reset
Reset = Confirm a rectified fault, reset device after test
routine, or confirm a change of configuration
LEDs, statuts information and fault messages (in
order of priority)
CM-MSS.12/13/22/23:
Operational state
Absence of control
supply voltage
Overtemperature
No fault
CM-MSS.11/21:
Operational state
Absence of control
supply voltage
Internal fault
1)
1)
Internal fault
Control supply voltage not
within tolerance range
2)
Short circuit

II DIP switch functions (CM-MSS.41/51)
c DIP switches for the adjustment of:
1
ON
= Non-volatile fault storage OFF
OFF = Non-volatile fault storage ON
2
ON
= Short-circuit detection OFF
OFF = Short-circuit detection ON
3
CM-MSS.41: no function
CM-MSS.51:
ON
= Single evaluation (2x1 c/o contact)
OFF = Accumulative evaluation (1x2 c/o contacts)
4
ON
= Remote Test/Reset
OFF = Remote Reset
Default setting: All DIP switches in position OFF
A change of the DIP switch settings is signaled by the
corresponding LED code. However, only actuating the Test /
Reset button or a restart will confirm the change of configuration.
III DIP switch position (CM-MSS.41/51)
Attention:
In case of switching currents > 2 A, lateral spacing to other units
has to be min. 10 mm (0.39 in).
With products that are used following the ATEX guideline
2014/34/EU, attention should be paid to the attached
instruction sheet „Additional information and notes on safety".
IV Connection diagrams
Series connection of 1 to max. 3 sensors type A per sensor
circuit.
Max. total PTC resistance 750 Ω.
The sensor circuit must not be earthed.
