Troubleshooting the Motor Driver FAULT ERROR LED:

On the bottom right hand corner of the master controller, look on the motor driver

PCB for LED activity upon power up. If the motor is connected properly, there will

ONLY be one LED that turns on right away on power up, it is the lower left Green

LED on the Motor driver board marked "PWR". The PWR LED indicates that the

motor driver board has 24volts. If the RED FAULT LED (near the center of the Motor

Driver board) is ON right away at power ON, then there is a problem between the

master controller and the motor. The problem may be that the CAT5 cable is

damaged or cross wired, or maybe connectors or wires are damaged on the

motor, etc. On the end of the motor, there are 5 wires that are associated with this

error: Black, Red, Blue, Green, and White. These wires have a 5 conductor plastic

connector attached that plug into the small circuit board on the motor. The order

of the colors are Black, Red, White, Green, Blue. Be sure that the CAT5 cable to the

motor is wired 'straight through', with no crossover. Keep all pairs together, do not

split any wires out of a pair. Each end of the CAT5 cable should be identical colors,

not mirrored colors.

When the connection problem is resolved, on power up the motor driver board will

only have the Green PWR LED lit up. The master controller on bootup does several

diagnostic routines. If the FAULT LED is LIT immediately on Power ONs, the system will

never boot up and pass the diagnostics test. First check that the MOTOR LOGIC

cable is plugged between the master controller and the motor. It may be required

to plug in the connector on each end several times to insure the copper

connections are cleaned. A good rule of thumb is to plug in the cable on each

end 5 times to clean the copper contacts on the plug. Also, inspect that the 5

wires from the motor are secure in the plastic connector. Gently pull on each wire

to see if one may have been broken, in which case the wire may pull out of the

connector.

A Fault on the Motor Driver indicated by the RED LED being on immediately at

power up is not a problem that can be solved with settings in the Master Controller.

NOTE: On some earlier versions of the Motor Driver circuit board (prior to 2013) the

Fault LED near the center of the board may have been GREEN. All newer boards

use RED.
