SINGLE WELL CONTROLLER
Solenoid (Shift Valve) Problems
Solenoid (shift valve) does not operate at any time or does
not operate at night
If the solenoid does not operate at night, the solar panel
may be powering the controller during the day.
Test 1: Check fuse.
With a screwdriver, move the power switch to off (see
1
page 3).
Remove the controller’s faceplate.
2
Remove the fuse from its yellow casing.
3
If the fuse is defective, replace it with a 5 amp, 250
volt fuse. The controller’s box contains 1 extra fuse.
When you are done, replace the controller’s
faceplate and move the power switch to on.
If the fuse is OK, go to Test 2.
Test 2: Check battery and wire connection.
The battery life is approximately 1 to 3 years.
The controller has a safety feature. If the battery voltage is
low, the controller closes the motor valve and shuts in.
Check the battery voltage with a volt meter.
1
Replace the battery if it is below 6 volts.
Check the battery wire connection.
2
Replace the controller’s faceplate.
3
With a screwdriver, move the power switch to on.
4
Check whether the solenoid is operating properly.
5
If the solenoid is now operating properly and if you
replaced the battery, check the manufacture date
on the battery. If the battery is less than 3 years old,
check the solar panel. Go to Test 3.
If the solenoid still does not operate, go to Test 4.
Test 3: Check solar panel.
Disconnect the solar panel from the terminals. Use a
1
volt meter to obtain the voltage and amperage. A good
solar panel reading in full sun exposure is 10.7 volts
and 350-430 mA.
If the solar panel is defective, change it.
2
Check the solar panel installation.
3
The solar panel should face south.
The tilt of the solar panel should be the latitude
of the location plus 15 degrees. Example: if the
latitude is 45 degrees, tilt the solar panel 60 degrees
with respect to the horizon.
The element should be free from dirt, oil, and so on.
Check for cracks in the solar panel.
Check whether the solar panel is shaded during any
part of the day. If it is, position it so it receives the
most sunlight each day.
Check the solar panel wire connection.
4
Make sure the power switch is on. The controller’s
5
display should be on.
If the solar panel tests good, but the batteries are not
6
lasting as long as they should, call your PCS sales and
service representative.
Test 4: Check solenoid (shift valve).
Press ON.
1
If the solenoid won’t open, clean the supply hoses and
2
puck inside the solenoid valve.
Retest.
3
If they are good, replace the puck or the entire
4
solenoid.
Transducer Problems
Display shows transducer reading of 0 psi
The surge protector or transducer may be defective, or
the transducer wire may have been completely cut.
Re-calibrate the transducer. See
1
Transducers” on page 8.
If the transducer won’t hold the calibration, change the
2
controller to Time Mode. Press SET 11 and enter 1.
Call your PCS sales and service representative.
3
Display shows fluctuating or false transducer reading
The transducer wire may be defective.
Re-calibrate the transducer. See
1
Transducers” on page 8.
If the transducer won’t hold the calibration, change the
2
controller to Time Mode. Press SET 11 and enter 1.
Call your PCS sales and service representative.

Battery
Always replace the controller’s battery when it is 3 years
old.
