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.
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.
NOTE: Continuous memory holds calibration snapshot even if power is absent.

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