Installation & Operation Manual
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
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.
