Ignition Sensing - Motorola VC70N0 Product Reference Manual

Ignition Sensing

The vehicle computer contains an Ignition Sense feature that detects when the ignition switch or key 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 or key 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. When the vehicle computer enters low power mode using the Ignition Sense feature,
current draw from the vehicle battery is reduced to less than 15mA and the vehicle computer consumes current
from it's internal battery. 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 or key switch. See
36V and 48V Batteries on page 2-3
