Remote reset (RST)
④
:
Alternatively, the reset can be performed using a remote reset signal (RST)
④
. The non-
isolated 24 V input (referred to the "0 V" terminal of the module) can be used at terminal
"RST". A reset is executed for an input level of > 15 V.
Note
The rising edge of the remote reset signal is evaluated, i.e. for an additional remote reset
signal, initially a voltage level of 13 V must be fallen below.
Using a remote reset signal at terminal "RST" all outputs that were shut down electronically
due to an overload are again reset. 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.
