Location of pressure switch for steering system

(1) Pressure switch for steering system

One pressure switch monitors the condition of the steering system.

Pressure switch (1) monitors the output of the steering pump. Pressure switch (1) is attached to a manifold that is mounted on the inside of the left frame.

The Vital Information Management System (VIMS) is designed in order to alert the operator of an immediate problem or impending problem in the steering system or other machine system.

The pressure switch is connected to the VIMS. At start-up, the alarm will sound and the alert indicator will flash until the steering pressure reaches the actuation pressure. If the system pressure drops to the deactuation pressure, the alarm should sound and the alert indicator should flash.

If the alarm sounds and the alert indicator is flashing this is an indication of a loss of primary steering flow. The accumulators will provide enough flow in order to allow the operator to steer the machine to a safe location off the road.

Note: A warning is only displayed if the ground speed is above 8 km/h (5 mph).
