Seat Switch Sensor - Yale Veracitor GCC040VX Operating Manual

Operating Procedures

Seat Switch Sensor

WARNING
Always make sure the parking brake is fully applied
before leaving the lift truck. If the operator leaves the lift
truck without applying the parking brake, a seat activa-
ted switch will shift the transmission to neutral, and
sound an alarm for 10 seconds. If the lift truck is left on
a grade, without the parking brake fully applied, the lift
truck will freewheel down the grade, possibly causing
injury or property damage.
These lift trucks are equipped with an Operator Presence
System (OPS). The OPS feature has an electrical switch in
the seat which senses the presence of the operator. This
allows the transmission in internal combustion engine trucks
to be engaged only when the operator is in the seat. The OPS
is designed with slight delay in the seat switch to allow the
operator to reposition himself without disengaging the trans-
mission. When the seat switch disengages the transmission
(neutral position), the operator must depress the service
brake pedal to re-engage the traction (travel mode).

A switch in the operator's seat will automatically shift the
transmission to neutral within 1-2 seconds when the operator
leaves the seat of the lift truck with the engine running and
without applying the parking brake.
If the lift truck is equipped with a Direction Control Lever and
the operator leaves the seat without engaging the parking
brake, the "N" indicator light on the Display Switch Cluster
will illuminate regardless of the position of the Direction Con-
trol Lever. When the operator returns to the seat, to resume
travel, the Direction Control Lever must be moved to the
"N" position, then to the desired direction of travel.
If the lift truck is equipped with a Foot Directional Control
pedal and the operator leaves the seat without engaging the
parking brake, the "N" indicator light on the Display Switch
Cluster will illuminate regardless of the position of the Foot
Directional Control pedal. When the operator returns to the
seat, the indicator light will change from "N" to the direction
of travel that the Foot Directional Control pedal was last in
when the operator left the lift truck. The operator can resume
travel by depressing the Foot Directional Control pedal.
