Override Key Switch
The indicator is fitted with motion cut control circuits, to control service
solenoids on the machine, to stop the machine opera�ng into dangerous
zones. In the event of a rated capacity system failure, it is possible to
over-ride the circuit for recovery purposes. The over-ride key switch is fitted
within a remote housing and protected by an anti-tamper seal. The key switch
will electrically open all the service solenoids to allow unrestricted use of the
machine. The external alarm will sound continuously when the override key
switch is used to override the machine hydraulics.
When overridden by the external key switch, the
3RCI+ screen at the operator sta�on will show a
warning message as indicated here.
With the Override key switch engaged, all hydraulic
func�ons are enabled regardless of load status or
limits set. All RCI func�ons are disabled and there
will be no protec�on against overload, or exceeding
any height or slew limits or virtual walls.
WARNING - WHEN OPERATING THE MACHINE WITHOUT THE RATED CAPACITY INDICATOR AND THE
SOLENOID OVERRIDE ENGAGED, DO NOT LIFT LOADS. OPERATE ONLY TO RECOVER THE MACHINE.
DURING THE RECOVERY OPERATION THE SYSTEM WILL CONTINUOUSLY LOG THE STATUS.
ONCE THE SEAL IS BROKEN THE MACHINE REQUIRES INSPECTION AND THE SEAL REPLACING BEFORE
BEING ALLOWED TO WORK ON TRACK.
