The PMD Series Phase Monitor Relays utilize a microprocessor-based design to provide
protection against phase loss, phase reversal, phase unbalance, undervoltage and
overvoltage. The PMDU is a universal voltage product that works on any three-phase
system voltage from 208-480V (separate 120V & 575V versions are available). These
devices are designed to be compatible with most Wye or Delta systems. In Wye systems,
a connection to a neutral is not required. PMD Series products protect against unbalanced
voltages or single phasing regardless of any regenerative voltages.
The relay is energized when the phase sequence and all voltages are correct. Any one of
five fault conditions will de-energize the relay. As standard, re-energization is automatic
upon correction of the fault condition. Manual reset is available if a momentary N.C. switch
is wired to the appropriate terminals. A multi-color LED indicates normal condition and also
provides specific fault indication to simplify troubleshooting.
The PMD Series offers a variety of user-adjustable settings. The percent phase unbalance
is adjustable from 2-10%, and also has a “Disable” setting for those applications where
poor voltage conditions could cause nuisance tripping. The undervoltage drop-out can be
set at 80-95% of operating voltage (overvoltage setting is fixed at 110% of nominal). The
adjustable time delay drop-out on undervoltage (0.1-20 seconds) eliminates nuisance
tripping caused by momentary voltage fluctuations. There is also an adjustable time delay
(1-300 seconds) on both power up and restart after a fault has been cleared.

MOUNTING
To order PMD units with a second N.O. contact instead of the N.C. (terminals 21-22),
add a suffix “-A1” to the Product Number, i.e., PMDU-A1. To order PMD units with
DPDT output contacts instead of one SPDT and one SPNC, but with no manual reset
feature, add a suffix “-A2” to the Product Number, i.e., PMDU-A2.
