Accuset Display Problems

If the Accuset display has no backlight when its control box is powered, check the power
light.

See Figure 3-1.

The rear of the Accuset front panel located in the control box is shown

below.

To check the power light, remove the eight screws securing the Accuset front panel.
Remove the front panel from its original location without disconnecting the wires. Turn the
key switch to the on (#1) or accessory (#3) position.

If the power light is on

, replace the control panel.

If the power light is off

, check the Accuset wire connections. Wiggle the wire connec-

tions to check if the power light flickers. Tighten the wire connections if necessary. Check
the up/down circuit breaker located in the operator’s control box, if the light is still off.
Reset the up/down circuit breaker as needed. If the circuit breaker is okay, call Customer
Service for assistance.

3.2.1 Control Panel Replacement

1.

Turn the key switch to the off (#0) position and remove the key.

2.

Remove the eight screws holding the control panel to the Accuset control box.

3.

Unplug the wire connections at the back of the control panel and remove the front panel.

4.

Install the new control panel to the Accuset control box. Make sure all the wires are tight
