Problem Typical Solution
Conductivity of the water is
reduced and is usually
caused by Low salt, cold
water, or a scaled cell.
1. Check the salt level and adjust to 3000 ppm (3.0 g/l) or verify salt
calibration.
2. For water temperatures below 65
°F (18.3°C), increase salt to
3500 ppm (3.5 g/l).
3. Remove and inspect the cell for white calcium scale. Follow the
instructions on pgs. 41 – 42 to clean the cell.
The salt level is below 2800
ppm (2.8 g/l) & temperature
below 70°F (21°C).
Increase salt level to 3500 ppm or increase temperature on heater if applicable.
The salt display differs from
salt test.
Adjust salt display in the Salt Calibration mode, see pg. 34 to calibrate.
The cell is scaled. * Determine frequency of scaling.
• ONE week or less = Power Supply not reversing polarity – contact factory
• TWO weeks or more = Water Chemistry related problem (check the
Saturation Index – see pg. 8)
Adjust water chemistry or adjust “Set Reverse” to a shorter cycle.
Warning!
Check /Clean
Cell
If this is a new installation… Verify that the incoming voltage matches the voltage of the Control Unit, see
pg. 13.
Cell is completely clogged
from calcium scale, has
failed, or the cell cord is
loose or damaged.
1. Check the cell for calcium scale build-up. Clean as needed.
2. Check for visual wear on the edges of the terminal blades.
3. Check the cell cord for tight connections on the cell and on the power
supply. Check the cell cord banana terminals and cell plug for burns.
Tighten or replace as needed.
The cell cord is disconnected Verify cell cables are inserted fully into the Digital base cell connector.
The cell is heavily scaled. Remove and acid wash as described on pgs. 41 - 42.
Warming!
Low Amps-
Cell?
If this is a new installation… Verify that the incoming voltage matches the voltage of the Control Unit, see
pg. 13.
Warning!
Low Amps-
Cell?
Warning!
Check/Clean
Cell
Cell is not receiving the
expected Amps.
Enter “Test Pool Pilot” mode through the menu. Write down the salt level,
water temperature, and cell volts and amps.
• If the volts are 28-29, then the problem is usually caused by low salt,
improperly connected, disconnected or loose cell cord, water less than 65
o
F
(18.3
°C), a scaled cell, or cell near end of life. Correct as appropriate.
• If the volts are less than 25, then contact AutoPilot Systems for assistance.
Installer:
If the unit is configured for 230 Vac operation, then verify that that
the input AC voltage is not 115 Vac. Fix wiring or recon figure the unit as
appropriate.
Warning!
Bad Temp
Sensor?
Temperature is out of range. 1. Check the Tri-sensor cable at both ends to make sure it is not disconnected
or loose.
2. Remove the cable at the Tri-sensor and verify that the pins are not be nt.
Plug it in, using care to orient it correctly before inserting it.
(Warning: Read warning, instructions and see illustrations in Connecting
the Tri-Sensor Cable on pg. 15)
3. Otherwise, contact AutoPilot Systems for assistance.
Warning!
Remote
Comm Error
The Electronic Control unit
is not sending
communication messages to
the Pool Pilot.
Turn the Electronic Control unit on.
Check for disconnected cable.
