2.9 Signaling contacts/control contacts
For two UPS modules in the system, the threshold that is set refers to the sum of the
charged battery modules in both UPS modules.

The signaling contact buffer mode "BUF" is in the form of a relay contact (NO contact,
terminals "23" and "24"
For two buffer components (UPS module, buffer module with signaling contact) in the
system, both modules simultaneously signal buffer mode using the signaling contact. It is
sufficient to wire one of the two contacts.

Or buffer mode with "ON "contact – or deactivated by a remote
•
command
Charge state of the UPS module or two UPS modules ≥ x %
Explanation
Normal operation.
Connected battery module is charged (if required).
Power failure, buffer mode
System is buffered via the buffer component(s).
Explanation
Incomplete connection to the battery module
•
(not available, cable (+, -) interrupted, fuse defective or ruptured)
Existing connection (+, -, COM1, COM2) is interrupted
•
Battery module is connected with reverse polarity
•
Alarm when the deep discharge limit is reached
•
Battery service life limit reached
•
Battery module has been deeply discharged
•
Service the connected BAT8600 (replace the batteries)
•
Firmware update
•
Normal operation (no fault in the connected battery circuit)
