Overload shutdown and carrying out a reset
For each device output, in the ELECTRONIC SHUTDOWN mode, overload is permitted for a
defined time. The output is electronically shut down after the limit value has been exceeded
(see the following diagram).
Shutdown characteristic
An output current up to the value set using the current potentiometer is continuously
permissible (LED "ON/OFF/RST" of the output is lit green).
In the range 101 - 149 % of the setting value of the current potentiometer, an overload
current is permissible for 5 seconds (LED "ON/OFF/RST" of the output flashes green), then
the output is electronically shut down (LED "ON/OFF/RST" of the output is lit red).
In the range > 149 % of the setting value of the current potentiometer, the current is limited
to 150 %, after approx. 200 ms the output is electronically shut down (LED "ON/OFF/RST" of
the output is lit red).
Using a reset, the output that has been automatically shut down can be switched-on again
after a wait time of 5 seconds (LED "ON/OFF/RST" of the output flashes red).
