Troubleshooting During Installation
Symptom Possible Cause Solution
Unit Appears Dead
(No Lights)
No Power to Unit
Check wiring. Power supply voltage should be applied
to the L1 and L2 terminals of the Pumptec-Plus. In some
installations, the pressure switch or other control device
is wired to the input of the Pumptec-Plus. Make sure this
switch is closed.
Flashing Yellow Light
Unit Needs to Be Calibrated
Pumptec-Plus is calibrated at the factory so that it will
overload on most pump systems when the unit is rst
installed. This overload condition is a reminder that the
Pumptec-Plus unit requires calibration before use. See
step 7 of the installation instructions.
Miscalibrated
Pumptec-Plus should be calibrated on a fully recovered
well with maximum water ow. Flow restrictors are not
recommended.
Flashing Yellow Light
During Calibration
Two-Wire Motor
Step C of the calibration instructions indicates that a
ashing green light condition will occur 2 to 3 seconds
after taking the snapshot of the motor load. On some two-
wire motors, the yellow light will ash instead of the green
light. Press and release the reset button. The green should
start ashing.
Flashing Red
and Yellow Lights
Power Interruptor
During the installation of Pumptec-Plus, power may be
switched on and o several times. If power is cycled more
than four times within a minute, Pumptec-Plus will trip on
rapid cycle. Press and release the reset button to restart
the unit.
Float Switch
A bobbing oat switch may cause the unit to detect
a rapid cycle condition on any motor or an overload
condition on two-wire motors. Try to reduce water
splashing or use a dierent switch.

High Line Voltage
The line voltage is over 253 Volts.
Check line voltage.*
Unloaded Generator
If you are using a generator, the line voltage may become
too high when the generator unloads. Pumptec-Plus will
not allow the motor to turn on again until the line voltage
returns to normal. Over voltage trips will also occur if the
line frequency drops too far below 60 Hz.
Solid Red Light
Low Line Voltage The line voltage is below 207 Volts. Check line voltage.
Loose Connections
Check for loose connections which may cause
voltage drops.
Loaded Generator
If you are using a generator, the line voltage may become
too low when the generator loads. Pumptec-Plus will trip
on under voltage if the generator voltage drops below 207
Volts for more than 2.5 seconds. Under voltage trips will
also occur if the line frequency rises too far above 60 Hz.
*Report high or low line voltage to the power company.
