Installation
6.3 Connecting the signaling contact/reset terminal
Power supply system SITOP PSU8600
156 Manual, 09.2018, A5E36758446-5-76
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.
Note
The contact rating is 30
V AC/0.5 A; 60 V DC/0.3 A; 30 V DC/1 A.
The signaling circuit must fully comply with the requirements relating to SELV circuits.
The precise function of the signaling contact is described in Chapter "Basic devices
(Page 58)".
You can obtain more information about the assignment of the signaling contact in Chapter
"Connections and terminal designations (Page 32)".
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 for this purpose.
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 of the p
ower supply system that
were switched off electronically due to an overload are reset at this time, assuming that the
wait time of 5
seconds of the corresponding output has elapsed.
