Phase Monitor
This sensor monitors voltage between the 3 conductors of
the 3 phase power supply. Two LED lights are provided:
• The green light indicates that a balanced 3 phase
supply circuit is properly connected.
• The red light indicates that unit operation has been
prevented. There are two conditions that will prevent
unit operation:
– The power supply circuit is not balanced with the
proper phase sequence of L1, L2, L3 for the 3
conductors of a 3 phase circuit.
– The line to line voltage is not between 180 volts and
633 volts.
