Dry Contacts not working
7.1 Service Technician Maintenance
This pump must be serviced by a professional service
technician qualified in pool/spa installation. The following
procedures must be followed exactly. Improper installation
and/or operation can create dangerous electrical hazards,
which can cause high voltages to run through the electrical
system. This can cause property damage, serious personal
injury, and/or death. Improper installation and/or operation
may void the warranty.
Before servicing the pump, switch off the circuit breakers
at the power source. Severe personal injury or death may
occur if the pump starts while your hand is inside the pump.

Make sure that there is adequate room around the motor to circulate air and keep the
motor cool. Have a qualified electrician check for loose connections and check the
voltage at the motor while it is in operatoin. If the main voltage is outside of 10% of
the motor rating plate, the motor may be experiencing excessive loads. Contact your
local power surface provider.
This is exclusive to any contoller that is not an automation system. The motor has the ability
to power controllers through the RS-485 line. Have a certified electrition test the voltage on
the RS-485 line while there is power to the motor. There should be between 8 and 12 Volts
DC between pins 1 and 4. If the voltage is below or non existant, contact Zodiac Technical
Support at 800.822.7933.
Improper low voltage wiring. Check the wiring of the RS-485 connector. Wire colors
for pins 1-4 should be Red, Black, Yellow, Green.
Make sure that the motor is spinning at least 1725 RPM for equipment wired to Aux
1 and 2250 RPM for equipment wired to Aux 2. When first turning on the pump, there
is a 3 minute delay before any contacts close. Allow 5 seconds before contacts close
when minimum contact speed is reached.
The problem may be with the equipment wired to the relay. See the owners manual
for the equipment to make sure the auxiliary equipment has not failed.
If the relays are still not engaging, contact Zodiac Technial Support at 800.822.7933
Test the drive with the RS-485 jumper method. Using small sections of 22 AWG wire,
jump pins 1 to 3 and 2 to 4. These wires can be made by cutting off a section of the
RS-485 wires. Re-install the connector and attach the access cover. Apply power to
the motor. The motor should spin at 2600 RPM indefintely. If the motor works, there
is a problem with the dry contacts or the dry contact lines. Contact Zodiac Technical
Support at 800.822.7933
Broken low voltage wiring. The wire may have breaks somewhere between the motor
and the external switches. With all power off, take a multimeter and set it to Ohms/
Continuity. Check continuity of each of the low voltage lines from the motor side to the
controller side. Replace the dry contact wires completely if necessary.

Installation & Operation Manual
Possible Cause/Solution
7.1.1 Blocked Impeller
1. Turn off the pump. Switch off the circuit breaker to
the pump motor.
2. Remove the lid and basket.
3. Look inside the pump and remove any debris.
4. Replace the basket and lid.
5. Switch on the circuit breaker to the pump motor.
6. Turn on the pump, and see if the problem is solved.
7. If the impeller is still blocked with debris and it
is not possible to remove the debris using Steps 2
through 4, the pump will need to be disassembled in
order to access the inlet and outlet of the impeller.
