Zodiac Pool Systems LLC strongly recommends that you call a qualified service technician to perform any repairs on the filter/pump system. To locate a qualified technician, check your local Yellow Pages or visit ZodiacPoolSystems. com or ZodiacPoolSystems.ca and click on “Find a Dealer.”

Symptom	Possible Cause/Solution
Motor won't start or the controller does not detect the motor	No power to the motor. Have a certified professional check the voltage on the main power terminal with the breaker on. The voltage must be within 10% of the motor rating plate voltage.
	The motor experienced an error. Power cycle the motor. If the motor has experienced an error, a fault code may appear on the controller. In order to clear the error, turn off the main breaker connected to the motor. Wait at least 5 minutes before returning power to the motor. The voltage in the capacitors must be completely drained for a proper power cycle.
	Improper low voltage wiring. The RS-485 connection must be secure with no broken wires. Inspect the low voltage wiring for signs of corrosion. If necessary cut the wires off and strip new leads. Make sure there are not any broken pieces of wire inside the RS-485 connector.
	Broken low voltage wiring. The wire may have breaks somewhere between the motor and the controller. 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 RS-485 wires completely if necessary.
	Improper low voltage wiring. Check the wiring of the RS-485 connector. Wire colors for pins 1-4 should be Red, Black, Yellow, Green.
	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 RS-485 line or with the controller. Contact Zodiac Technical Support at 800.822.7933
	DIP switches in the wrong configuration. The variable speed drive has two DIP switches; 3 and 4. These must both be in the OFF position for Pump 01. This is the configuration for all controllers that are not automation and the first pump for automation. If more than one variable speed pump is being controlled with an automation system, they must be in the proper configuration. Refer to the DIP switch section of the manual to configure the other motors.
	Check the schedule. The motor will only turn on during programmed times set in the controller. Verify that the motor is scheduled to turn on at that time.
	If the motor still has problems starting or continues to show faults, contact Zodiac Technical Support at 800.822.7933
Motor starts but shuts off soon after	Debris may be stuck between the impeller and the diffuser. This will prevent the drive shaft from spinning and will cause the motor to experience an error. Have a certified professional check to see if the drive shaft is seized with all power off. A quick test can be inserting a 5/16" allen wrench through the back of the fan housing and into the drive shaft. Manually spin the drive shaft to check if it is seized. If large amounts of debris are found, check your strainer basket for breaks. Replace the strainer basket if necessary.
Motor starts but shuts off soon after	If the motor still has problems starting, contact Zodiac Technical Support at 800.822.7933
The motor gets hot and shuts off periodically	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 operation. 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.
No power to controller	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 electrician 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.
No power to controller	Improper low voltage wiring. Check the wiring of the RS-485 connector. Wire colors for pins 1-4 should be Red, Black, Yellow, Green.
Dry Contacts not working	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
Dry Contacts not working	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.
