Feed the relay with the minimum and maximum voltage. For each voltage value, verify that the alarm relay is activated
when there is voltage, and it is deactivated when there is no feed. If the power supply source incorporates AC feed, this test
will be performed also for VAC.
If the relay incorporates a redundant power supply, these tests shall be performed on both power supplies.
Voltage values to be applied will be the ones indicated below according to the relay model:
