module). These functions are described in the manual of the Mico Pro power
module.
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 terminal
Signal output signal for connection to PLC inputs
 Alarm signal level: "high" U
in
/ 20 mA
When the consumer circuit (channel) is connected.
 Alarm signal level: "low" 0 V DC
When the consumer circuit (channel) is disconnected.
Control output
90-% terminal
Signal output signal for connection to PLC inputs
 90-% signal level: "high" U
in
A load of >90 % of the tripping current is measured on the consumer circuit
(channel).
 90-% signal level: "low" 0 V DC
A load of <90 % of the tripping current is measured on the consumer circuit
(channel).
