The following readings are not available: RMS Voltage, Real Power and Apparent Power
2)
The ‘TEACH’ operation cannot be executed
3)
Voltage out of range and Load deviation alarms are not available

The mains loss alarm cannot be discriminated from a load loss. Therefore, a mains loss alarm will indicate
either a mains loss or a load loss.
