to the line voltage on the load side of the
last line fuse before the motor and on the
line side of the starter (MS).

Operation
The PVM-P’s output contacts
energize when:
1. All the phases are present;
2. The voltages are within set points;
3. The phases are in proper rotation.
If any of these conditions shift
beyond the setpoints, the output
contact will de-energize after a .2
second fixed time delay period.
Single phase conditions will only be
detected if there is a substantial loss
of voltage in one phase. In some
applications, motors that continue to
rotate after the loss of a phase may
re-generate voltages that simulate
the line conditions. Consider R-K’s
PVC or PVR series if loss of phase
is critical in your applications.
