PUMPTEC-PLUS Pump Protection System
7. Calibrate
Before the Pumptec-Plus unit is ready for use it MUST BE CALIBRATED. The calibration
procedure is quick and as simple as taking a snapshot.
Calibration may be performed as many times as desired by following steps A, B, and C
below.
A. Press and hold in the reset button on the bottom of the Pumptec-Plus enclosure until
the green, yellow, and red lights blink alternately. This should take approximately 10
seconds. You will hear the Pumptec-Plus contactor engage and the motor should
start. Release the reset button. Steps B and C must be completed within three
minutes or the calibration procedure will be aborted.
B. Verify that the pump system is running normally (i.e. the system is pumping water
and the motor current is normal). Try to achieve maximum water flow rate. Calibration
on a fully recovered well is recommended.
C. Briefly press the reset switch again and then release it. You have just taken a
snapshot of the motor load. All indicator lights will go off. After 2 to 3 seconds,
the green light will start flashing, indicating the system is running normally and
calibration is complete. Over/underload trips will occur at 125% and 75% of the
snapshot load.
NOTE: Continuous memory holds calibration snapshot even if power is absent.
CAUTION

Operation

Under normal operating conditions, Pumptec-Plus requires no special attention. The
power line voltage and motor power draw are continuously measured. If a fault condition is
detected, an indication is given by a light on the front panel and the motor is disconnected
from the power line.
Pumptec-Plus measures the actual motor power (Watts), not motor amps or power factor.
The motor power draw at the moment of calibration is permanently memorized by Pumptec-
Plus. If the motor power draw differs from the memorized calibration power by more than ±
25%, Pumptec-Plus will turn off the pump motor. It is very important to make sure the pump
system is running normally during the calibration process.
There are three indicator lights (A, B, and C) visible through the front cover. Each light is a
different color and each has a special meaning. Also, on the bottom of the unit enclosure
is a reset button (D). The purpose of each light and the operation of the reset button are
described on page 5.

Pumptec-Plus should only be calibrated by qualified service personnel.
Calibration on a faulty pump system will not provide protection.
