Connecting The Control Contact And Signaling Contacts Of The Buffer Module - Siemens PSU8600 Manual

6.6 Connecting the control contact and signaling contacts of the buffer
module
Buffer modules with double-layer capacitors have one control contact and two signaling
contacts.
● Buffer operation can be enabled, inhibited or exited using control contact "X1" and "X2".
● Information about the charge state of the buffer module can be obtained via signaling
contact "13" and "14".
● Information about buffer operation can be obtained via signaling contact "23" and "24".
Control contact
The control contact is implemented as contact pair and when delivered 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, therefore unnecessarily discharging the buffer module. Buffer operation is
immediately exited if the contact is opened during buffer operation.
Note
When closed, the contact must have a resistance < 10 Ohm.
The precise function of the control contact is described under Buffer modules (Page 42) and
in Section Activating and deactivating buffer operation (Page 81).
You can obtain more information about the assignment of the control contact under
Connections and terminal designations (Page 23).
Signaling contacts
The signaling contacts are NO contacts, and allow information about the operating state of
the buffer module to be processed further.
Note
The contact rating is 60 V DC/0.3 A
The precise function of the signaling contacts is described under Buffer modules (Page 42).
