7.4 Control and signals
7.4.1 Mico Pro PS / Mico Pro PM
The control and diagnostic functions described on the Mico Pro PS (power
supply) / Mico Pro PM (power module) are group signals from or for the entire
Mico Pro system (Mico Pro PS / Mico Pro PM with added system compo-
nents). If Mico Pro PS (Art.-No. 9000-41190-0000110) is used in parallel
mode, signals are available only on the power supply next to the Mico Pro
channels.
ON terminal
(restart)
control input
Signal for control via a PLC
ATTENTION:
- If a consumer circuit (channel) is disconnected manually using the "ON/
OFF" button, it can only be reconnected manually by means of the "ON/
OFF" button .
- If a consumer circuit (channel) is disconnected via the "CTRL" terminal, it
can only be reconnected via the "CTRL" terminal .
 ON signal level: "low" (0 V ... 1 V DC)
 ON signal level: "high" (9 V ... 30 V DC), min. 120 ms
Consumer circuits disconnected due to overload can be reconnected with
this signal.
Control input
CTRL terminal
Signal for control via a PLC
ATTENTION:
- If a consumer circuit (channel) is disconnected manually using the "ON/
OFF" button, it can only be reconnected manually by means of the "ON/
OFF" button .
- If a consumer circuit (channel) is disconnected via the "CTRL" terminal, it
can only be reconnected via the "CTRL" terminal .
 CTRL signal: "low" (0 V ... 1 V DC)
 CTRL signal: "high" (9 V ... 30 V DC), 40±3 ms / 400±30 ms,
Consumer circuits (channels) are disconnected.
 CTRL signal: "high" (9 V ... 30 V DC), 20±3 ms / 200±30 ms,
Consumer circuits (channels) are connected.
 CTRL signal: "high" (9 V ... 30 V DC), >600 ms,
Consumer circuits (channels) are disconnected.
 CTRL signal: "high" (9 V ... 30 V DC), CTRL&ON >500 ms,
Consumer circuits (channels) are connected.
Control output
Alarm 13, 14
Terminals
Potential-free
Terminal contact group signal output max. 30 V AC/DC, 20 mA
 Alarm contact: contact closed
All consumer circuits (channels) in the system are connected.
 Alarm contact: contact open

Control output
90% 23, 24
Terminals
Potential-free
Terminal contact group signal output max. 30 V AC/DC, 20 mA
 90% contact: contact closed
A load of >90% of the tripping current is measured on at least one consum-
er circuit (channel) in the system.
 90% contact: contact open
All consumer circuits (channels) in the system are measured with a load
of <90% of the tripping current.
