Connecting the signaling contact/reset terminal
The combined signaling contact/reset terminal has two functions:
●
Information regarding the operating states can be called up using signaling contacts "12",
"11" and "14".
●
A remote reset can be implemented using input "RST.
Signaling contact (changeover contact)
The signaling contact is implemented as changeover contact (NC contact: terminals "11" and
"12", NO contact: terminals "11" and "14"), and allows information about the operating states
of the power supply system and the outputs to be processed.
Contact rating:
60 V DC/0.3 A
The precise function of the signaling contact is described under Basic devices (Page 37).
You can obtain more information about the assignment of the signaling contact under
Connections and terminal designations (Page 21)
Reset terminal
A 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.
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, assuming that the wait time of 5 seconds of the
corresponding output has elapsed.
