SECTION 12: Motor Protective Devices - 50/60 Hz
12.1 How They Work
Pentek motor protectors are designed to protect single
®
phase pumps from dry run, dead head, jammed impeller,
and over & under voltage conditions.
A calibration adjustment allows the motor protector to
be calibrated to specific pumping applications, thereby
reducing the possibility of false or nuisance tripping. A
micro drive based voltage and current sensing circuit
monitors for power fluctuations, over-current, and under-
current conditions. When an abnormality, such as loss
of suction, is detected, the motor protector deactivates
its output relay and immediately disconnects the pump
motor. The motor protector then activates its user-

When the timer counts to zero or power is removed and
reapplied, the motor protector reactivates its output relay
and turns the pump back on.
An infrared LED communicates directly with a hand-held
diagnostics tool called the Informer (sold separately). The
Informer displays 16 parameters including calibration
point, trip point, running points, and last fault.
NOTICE: The use of flow restrictors or unusually high
head pressures at the time of calibration may interfere
with the detection of dead head conditions.
