SOLUTION
•
Check for debris stuck between impeller and diffuser.
•
Have a certified professional check to see if the drive shaft is seized with all power
off.
•
If large amounts of debris are found, check your strainer basket for breaks. Replace
the strainer basket if necessary
•
Ensure adequate room around motor for air circulation to keep motor cool.
•
Have a qualified electrician check for loose connections and check voltage at
motor while in operation. Main voltage outside of 10% of motor rating plate may
cause motor to experience excessive loads.
•
Have a certified electrician test voltage on RS-485 line while power is available to
motor. It should be between 8 and 12 Volts DC between pins 1 and 4.
•
Check RS-485 connector wiring (pins 1-4 should be Red, Black, Yellow, Green).
•
Test motor drive with RS-485 jumper method: Using small sections of 22 AWG
wire, jump pins 1 to 3 and 2 to 4. Re-install connector and attach access cover.
Apply power to motor to see if motor spins at 2600 RPM indefinitely. If motor
works, the issue is with the RS-485 line or controller.
•
Check low voltage wiring for breaks between motor and external switches. With
all power off, use a multimeter to check continuity of each low voltage lines from
motor to controlle. Replace the dry contact wires completely if necessary.
