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
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.
Connect the yellow wire to the vehicle's ignition switch. If you do not plan on using the Ignition Sense feature,
