B2000 Circuit Board Error Codes.

A troubleshooting aid exists on the printed circuit board
mounted to the inside of the operating handle. A white L.E.D.
will flash once every two seconds after power up. The L.E.D.
indicates all systems functional. See the Figure below.
Error codes consist of different light patterns.

1. Blink twice, pause, blink twice = the motor is over heated.

2. Blink 3 times, short pause, blink three times, long pause =
limit switch has failed.

3. Blinks 4 times, short pause, blinks four times, long pause =
pendant control malfunction.

In addition the L.E.D. will be steady on if the bend or return
button is being pressed.
