PMP-25 Pump Load Control
Installation, Set-up & Adjustment
The Model PMP-25 monitors the true power going to a
motor. By sensing power (volts x amps x power factor)
rather than just amps, there is much greater sensitivity. For
loss of load detection, this means a 10X improvement in
performance.
Mounting:
Wiring is done to un-pluggable terminal strips on the rear of
the unit. Three ways to mount:
•• On door or raceway – use cutout template
•• Panel Mount – use template + optional Bezel Kitt
t
(No Charge)
•• On wall – on standard outdoor junction box +
optional
•• Outlet Box Adapter (No Charge)
Voltage:
120 volts AC is taken from two of the phases. If the motor starter already has a 120-volt control transformer with
10VA of free capacity, it can be used. Otherwise, install a separate transformer. It is okay if the secondary is
grounded.
BE SURE TO NOTE WHICH TWO PHASES SUPPLY THE TRANSFORMER.
In 120/208V three-phase system, the 120V MUST come from a transformer connected to two of the phases. The
120V phase to ground voltage cannot be used.
The current signal is taken from the REMAINING phase. This current sample passes
through the Range Finder Toroid.
It is VERY IMPORTANT that the current signal comes from the phase that IS NOT
supplying the 120V control transformer. Be extra careful when the machine has reversing
starters or multi-speed windings. If a wrong phase is used the control will either:
•• Work backwards
•• Have reduced sensitivity
