Monitoring the batteries

Various test are performed during operation to evaluate the buffer capability of the
connected battery module and the calculated maximum available residual capacity of the
batteries used in the BAT1600 battery module.
Cyclic battery test
The cyclic battery test is used to check the usability of the connected battery module.
The test is automatically performed when the system is not in the buffer mode, and the
battery module has an adequate charge state.
The starting point for the time interval is set when the system runs up. An interval that has
already been started is reset if in the meantime, buffer mode has occurred or the system has
been restarted.
The voltage of the battery module and the individual batteries is evaluated while the test is
being performed. The test is evaluated as negative if an excessively high voltage dip occurs.
The battery module is identified as being unusable after three consecutive negative test
results.
The following signals indicate a battery module that has been identified as unusable:
• Red LED "BAT" at the UPS module
• Red LED "O.K." at the battery module
• Signaling contact "O.K." at the UPS module
Replace a battery module or the batteries in the battery module that has/have been identified
as unusable (see Chapter Replacing batteries in a battery module (Page 231)) to restore the
system buffer readiness.
