Electronic shutdown was reset, and the output has been switched-on again (LED
"ON/OFF/RST" of the output is lit green).
Note
If, after a reset, the cause of the overload is still present, then the output is again
automatically shut down according to the shutdown characteristics described previously.
Before carrying out a reset, remove the cause of the overload to prevent a new shutdown.
Remote reset via terminal RST
The reset can be alternatively carried out using a remote reset signal. The non-isolated 24 V
input (referred to terminal "0V" of the device) at terminal "RST" can be used. A reset is
carried out for an input level of > 15 V for at least 100 ms.
Procedure
Connect a voltage of > 15 V for at least 100 ms to terminal "RST".
The reset is carried out.
Note
Using a remote reset signal at terminal "RST" all outputs that were shut down electronically
due to an overload are reset at this time (precondition: The output is ready for a reset, i.e.
the shutdown occurred more than 5 seconds beforehand).
If a switch-on delay of the outputs is defined when switching on, this is not taken into account
for a reset initiated using a remote reset signal.
Note
The rising edge of the reset signal is evaluated; this means for an additional reset signal, the
voltage level must first drop down to below 13 V.
