8.6 Control Supply Module CSM
Booksize Power Units
538 Manual, (GH2), 07/2016, 6SL3097-4AC00-0BP8
A maximum of 10 Control Supply Modules can be connected in parallel.
The DIP switch of the Control supply Module must be set to "parallel mode". The same
output voltage must be set for all modules at the potentiometer.
In the parallel mode, each Control Supply Module should supply the 24 V DC voltage via the
24 V terminal adapter. This is the reason that the 24 V connector must
be used (see
connection examples).
For a parallel connection we recommend that a SITOP redundancy module (6EP1961-
3BA20) is used. One SITOP redundancy module must be used for two Control Supply
Modules in this case. Alternatively, a connection with external diodes to decouple the
individual Control Supply Modules is possible. If a Control Supply Module fails, an alarm is
generated and provided via the X21 signaling contact. The 24 V supply is maintained via the
second module.
Note
Parallel connection
Only Control Supply Modules with article number 6SL3100
-1DE22-0AA1 may be used for
.
