Ignition Sensing

The vehicle computer contains an Ignition Sense feature that detects when the ignition switch is turned off and
shuts the vehicle computer down after a preprogrammed timeout. This feature allows the operator to use the
vehicle computer for a predetermined time period after the ignition switch is turned off, then shuts the vehicle
computer down automatically to prevent over-discharge of the forklift battery. The timeout period is adjustable by
the user. The normal current draw of a suspended vehicle computer is approximately 500mA. When the vehicle
computer shuts down using the Ignition Sense feature, current draw is reduced to approximately 5 mA. This feature
provides the automatic shutoff functionality of an external relay, without requiring an actual relay and has the added
benefit of allowing the user to work for a preset time period before shutting down.
The power cable must be connected to the ignition switch. See
connecting the power cable to enable the Ignition Sense feature.
NOTE These settings are not persistent across a cold boot.
