the manual position, then the reset button must be pressed to
reactivate the unit. |
| Blocked Intake |
Clear or replace pump intake screen. |
| Blocked Discharge |
Remove blockage in plumbing. |
| Check Valve Stuck |
Replace check valve. |
| Broken Shaft |
Replace broken parts. |
| Severe Rapid Cycling |
Machine gun rapid cycling can cause
an underload condition.
See flashing red and yellow lights section below. |
| Worn Pump |
Replace worn pump parts and recalibrate. |
| Yellow
Flashing Light |
Stalled Motor |
Repair or replace motor. Pump may
be sand or mud locked. |

two-wire motors to stall.
Arrange plumbing to avoid splashing water. Replace float switch. |
| Ground Fault |
Check insulation resistance on motor
and control box cable. |
| Solid
Red Light |
Low Line Voltage |
The line voltage is below 207 volts.
Pumptec-Plus will try to restart the motor every two minutes
until line voltage is normal. |
| Loose Connections |
Check for excessive voltage drops
in the system electrical connections (i.e. circuit breakers,
fuse clips, pressure switch, and Pumptec-Plus L1 and L2 terminals).
Repair Connections. |
| Flashing Red Light |
High Line Voltage |
The line voltage is over 253 volts.
Check line voltage. Report high line voltage to the power company. |
| Flashing
Red and Yellow Lights |
Rapid Cycle |
The most common cause for the rapid
cycle condition is a waterlogged tank. Check for a ruptured
bladder in the water tank.
Check the air volume control or snifter valve for proper operation.
Check setting on the pressure switch and examine for defects. |
| Leaky Well System |
Replace damaged pipes or repair leaks. |
| Stuck Check Valve |
Failed valve will not hold pressure.
Replace valve. |
| Float
Switch |
Press and release the
reset button to restart the unit.
A bobbing float 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 different
switch. |
