may observe a brief excursion of the battery recharge current beyond the BCL
setting.
Check Manual Equalise (if configured). Click the Start Manual Equalise button on the
Charge page to initiate a battery equalisation. Click the Stop button at the top of the
Charge page to end.
A Battery MCB Fail alarm is generated from the voltage measured across the battery
MCB.
Therefore, to check a Battery MCB Fail alarm, simply open one of the battery MCB's. If
batteries are connected to the system at this time, the alarm may take a few moments
to activate. Once test is complete, turn breaker back on.

Temperature Compensation
Check Temperature Compensation is enabled.

Apply heat or cold to the Battery Temperature Sensor/s. Check
float voltage moves up or down as expected.
If actual measurement is required, apply a known heat or cold to Temp.______°C
the sensor. Allow it to fully come to temperature and record the amount of
voltage movement.
Check Alarm Relay Contacts
To generate these alarms, refer to the procedures described earlier in the Commissioning
Checklist.
Spare relays will not be able to be tested unless an alarm is mapped to them. As these
are tested in the factory, it is not essential to test them at time of commissioning.

Relay 1 (Monitor Fail)
(pull out the RJ45 lead connecting the monitor to the system rectifier shelf – this
simply de-powers the monitor)
Relay 2 (Summary Non-urgent)

that the system is to be left on (to power load equipment, ensure rectifiers are left in their powered-up state, and batteries
are in circuit. This will prevent anyone leaving the batteries only powering the load (in which case the batteries go flat).
11.3 Systems with Lithium Batteries
The term lithium batteries include a wide range of chemistry types. Regardless of the chemistry used the energy manager
differentiates lithium (and other non-lead acid batteries) by whether the battery BMS can be communicated to via Modbus
RTU or not. These 'smart' batteries are termed modular, where the energy manager is receiving information on alarms and
status from the battery internal electronics.
