Wedge Service Diagnostic Display
The WEDGE controller provides a diagnostic capability that allows various machine parameters
to be viewed on the numeric display. The diagnostic display can be accessed with the machine
stopped or while it is operating. The “Data Input” switch located beside the WEDGE controller
inside the unit is used to toggle through the list of parameters.
If the “Data Input” switch is broken then the following method can be used: If the
machine is stopped, the “Service Air” switch on the control panel is used to toggle through the list
of parameters. If the machine is operating, the “START” position of the ignition switch is used to
toggle through the list of parameters.
To view the parameters, use the “Data Input” switch to scroll to the desired display
number. After 1 second, the display number will disappear and the desired parameter will be
displayed. After 3 minutes, the display will return to normal mode. The toggle only works in the
ascending order direction, but it will wrap around and start over.

Entering Machine ID for WEDGE Control Systems
For machines with the WEDGE controller mounted inside the control
panel/instrument panel box, the "Service Air" switch is used to enter the machine
ID. Disconnect the fuel level sensor (if equipped, will be located in the fuel tank),
before starting the process and reconnect once the process is completed.
