Battery Information
The system is designed to operate
most efficiently with sealed lead acid
(SLA) batteries at 24 volts. Two 12-volt
40-amp hour SLA batteries provide
22"
enough energy to pump more than
10,000 gallons of water from a
basement. Deep cycle marine batteries
Brick
can also be used.
Sealed lead acid batteries cost slightly
more, but they can last longer. Wayne

"Click" inside PS/BC.
An overload is
indicated when you
hear a distinct "click"
from the DC circuit
breaker internal to the
PS/BC. A 3-5 minute
cooling off period
occurs before the PS/BC
resets itself. If the
overload condition still
exists, the cycle will
repeat. Regardless of
what is causing the
circuit breaker to cycle,
unattended or routine
operation in this
manner could result in
serious damage to the
PS/BC and the battery.
Possible Cause(s)
Corrective Action
1. Power outage
1. None
2. Blown AC breaker
2. Push AC breaker to reset. If breaker trips again, do not reset.
Have unit checked by qualified electrician
3. GFCI tripped
3. Reset GFCI
4. Low AC voltage
4. Have outlet checked by electrician
1. Pump fuse may be blown
1. Replace pump fuse. Use Bussmann AGC10 or Littlefuse 312010
2. Pump impeller may be
2. Remove impeller. Check for damage to bore or bearing
damaged
Low battery
Apply AC power or replace batteries
1. Battery polarity is incorrect
1. Recheck battery polarity
2. Battery voltage too low
2. Replace batteries
1. Lower float stuck
1. Remove filter and clean. Remove debris from float switch area
2. Pump too low in sump
2. Place a brick under the pump
1. Pump power cord
1. Check for proper installation of power cord into the PS/BC
2. Upper float switch stuck
2. Remove filter and clean. Remove debris from float switch area
3. Impeller rotor jam
3. Remove filter and clean. Remove debris from float switch area
1. Backflow from discharge
1. Install or replace check valve
pipe
2. Pump too low in sump
2. Place a brick under the pump
3. Clogged pump filter
3. Remove filter and clean
1. Blocked discharge pipe
1. Check for restrictions in discharge line, flood is immanent. Shut
off AC power before entering flooded area
2. Partially clogged pump
2. Remove impeller, check for debris in inlet
filter
3. Broken thrust bearing
3. Remove and inspect thrust bearing
1. Discharged battery
1. If the battery is in otherwise good condition, it is normal for
the circuit breaker to cycle ON and OFF several times before
the battery recovers enough to allow a normal charge rate. If
this happens on a regular basis, however, the batteries may be
too large for the PS/BC and it could be damaged. Replace
batteries
2. Shorted cell battery
2. A battery in this condition may cause the breaker to cycle
continuously. The battery will not accept a charge. Replace
both batteries
