Display Rev Level

This entry displays the revision level of the software within the control board.

Fault Recall

This entry displays any fault codes stored in memory. Refer to Main Controller Error Codes described on
page 23 for a list of error codes. If no fault exists, the display will show "--".

Fault Detection

This option will allow service personnel to override some of the fault detection checks to facilitate
troubleshooting. If a fault occurs in a particular system, that system (and possibly others) will be shut down.
This can make troubleshooting the system difficult. This will not disable the over-current protection on
any of the systems. Important: Make sure to turn Fault Detection back on (Enable) before returning the
machine to normal operation.

Service Test Mode

Service test mode provides access to all of the machine's motor and solenoid functions. This allows the
technician to exercise the components for testing and troubleshooting. Refer to Service Test Mode described
on page 25 in the Troubleshooting section for a description of the options. (Note: Exiting Service Test
Mode requires turning off the key switch.)

Backup Alarm Vol (Volume)

Whenever the machine is moving in the reverse direction, the backup alarm can sound to notify bystanders
that the machine is backing up. There are 4 options for the volume, including disabling the function (off, low,
medium, and high).

FWD Alarm Vol (Forward)

Whenever the machine is moving in the forward direction, the forward alarm can sound to notify bystanders
that the machine is moving forward. This may be beneficial if the machine is used in high traffic areas with
many bystanders. There are 4 options for the volume, including disabling the function (off, low, medium, and
high).

Horn Volume

The horn will sound when the horn switch is pressed. There are 4 options for the volume, including disabling
the function (off, low, medium, and high).

Panel Test

This diagnostic function is used to test the lights and switches (buttons) of the machine display. When
activated, all of the lights on the display will be illuminated. As each switch on the display is pressed, the
LCD will display the name of the button, and a counter to indicate how many buttons have been pressed. To
exit the Panel Test mode, the key switch must be turned to the off position.

Troubleshooting Guide

Any error codes detected by the main control board will be shown on the display panel as they occur. If more
than one error exists the display will sequence through the error codes at one-second intervals. The error
will display as a mechanical wrench symbol (F5) followed by a two-digit code (F6).
