An individual output can be reset using the button. This resets the electronic shutdown of the
output, caused by an overload condition.
The initial situation is an electronic shutdown of individual outputs as a result of an overload
condition. This is signaled using the LED
LED
Lit red
Flashes red
Lit green
Procedure to reset an electronic shutdown:
1. After an electronic shutdown (LED of the output is lit red), allow a wait time of 20 seconds
to elapse.
2. Press the reset button
Electronic shutdown was reset, and the output has been switched-on again (LED of the
output is lit green).
Remote reset:
Alternatively, a remote reset signal can be used. The non-isolated 24 V input (referred to
terminal "0 V" of the module) at terminal "RST" can be used for this purpose. A reset is
carried out for an input level of > 15 V.
Using a remote reset signal at terminal "RST" all outputs that were shut down electronically
due to an overload are reset at this time. Prerequisite: The output is ready to be reset, i.e.
the electronic overload shutdown occurred longer than 20 s ago (LED of the output flashes
red).
Note
If, after a reset, the cause of the overload is still present, then the output is again
automatically shut down. Before carrying out a reset, remove the cause of the overload to
prevent a new shutdown.
