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 on page 2-10 for
information on connecting the power cable to enable the Ignition Sense feature.
