COMMANDS MENU
– The commands menu allows executing some occasional operations like reading peaks or counters or alarms clearing, etc.
– If the Advanced level password has been entered, then the commands menu allows executing the automatic operations useful for the device configuration.
– The following table lists the functions available in the commands menu, divided by the access level required.

– Once the required command has been selected, press
executed.
– To cancel the command execution, press keys L and M simultaneously.
– To quit the commands menu simultaneously press key L and M.
WIRING TEST
– The wiring test allows to verify if the connection of the device has been executed properly.
– To be able to execute the test, the device must be connected to an active plant, with the following conditions:
• Three-phase system with all phases presence (V > 50V~ L-N)
• Current flowing in each phase > 1% of the CT primary.
• Positive flow of energies (that is a normal plant where the inductive load draws power from the supplier).
– To launch test execution, enter commands menu and select the required command per commands menu instructions.
– The test allows to verify the following points:
• Reading of the three phases
• Phase sequence
• Voltage imbalance
• Reverse polarity of each CT
• Mismatch between voltage and current phases.
– If the test does not succeed, the display shows the reason of the failure.
– If instead the test succeeds, then the condition is stored in the non-volatile memory, and a message that states the test successfully completed is shown in the
information page.
