Connecting the control contacts and signaling contacts of the UPS
module
The UPS module has two control contacts and three signaling contacts.
●
The buffer mode can be enabled, inhibited or exited using control contact "X1" and "X2"
("ON").
●
Control contacts "X3" and "X4" ("START") define whether the system starts with the
energy saved in the battery modules - or not.
●
Information about the charge state of the battery module connected to the UPS module is
available via signaling contact "13" and "14" ("READY").
●
Information about buffer mode can be obtained via signaling contact "23" and "24"
("BUF").
●
Information about fault-free operation of the battery circuit connected to the UPS module
is available via signaling contact "33" and "34" ("OK").
Control contacts
The control contacts are implemented as contact pair.
When supplied, control contact "X1" and "X2" ("ON") has a wire jumper. Instead of the wire
jumper, a floating contact can be switched in the plant or system. This means for a
scheduled operational shutdown of the power supply, buffer operation is prevented, so that
the buffer module is not unnecessarily discharged. Buffer mode is immediately exited if the
contact is opened during buffering.
When supplied, control contact "X3" and "X4" ("START") is open.
Note
When closed, the contacts must have a resistance < 10 Ohm.
For the function of the control contacts, see

operation) (Page 102)"
