motor operating device is fitted to the disconnector.

3. Battery condition monitoring

The Wireless Controllers REC601/603 are
equipped with condition based functionality that
make the conditioning monitoring of the built-in
battery of the device possible and optimize the
lifetime and maintenance intervals of the back-up
batteries in the control assembly.
The back-up battery could periodically (scheduled
by operator) be tested by switching off the
charger and switching on the dummy load.
Current and voltage measurements are taken for
a defined period of time (discharging time period).
Based on these measurements of the battery's
current and voltage levels, an assessment is
made regarding the battery's condition and

remaining operational capacity (in Ah). If the
assessment shows that the battery has a
significant depletion in capacity an IEC
60870-5-104 alarm event would then be
generated in the system.
Also the Wireless Controllers REC601/603 feature
the ability to protect the battery against complete
discharge. This is achieved by the fact that the
battery voltage is always measured in network
fault conditions (primary power source is
disconnected). If the measured battery voltage
level is below a defined limit (assumed as a
"battery failure") an IEC 60870-5-104 alarm event
would then be generated in the system and the
load is disconnected from the battery.
