critical processes can be immediately brought into a safe state, avoiding loss of data and
additional damage.
For two BUF8600 buffer modules with double-layer capacitors in the system, both modules
simultaneously signal buffer mode using the signaling contact. As a consequence, it is
sufficient to wire one of the two contacts. The signal "Buffer mode" refers exclusively to the
BUF8600 buffer modules with double-layer capacitors in the system.
BUF8600 buffer modules with electrolytic capacitors in the system are not taken into
account.
Signaling contact
Explanation
23-24 open
(quiescent state)
Power failure, system is buffered by the buffer module.
23-24 closed
Normal operation, buffer module is charged (if required).
