NOTE
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 (see Ignition Sensing on page 3-17 for setting the timeout value).
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.
