standards required for use in the marine environment.
In order to ensure conformance and to prevent interference with
electronic systems the unit must be properly bonded to earth and the
supply cables screened.

EMERGENCY QUICK RELEASE
In the unlikely event of failure of the actuator a quick release R-Clip is fitted
to the tiller bolt which secures the actuator to the steering quadrant.
Pull the red tab to release the R-Clip and then manually lift the actuator
clear of the steering quadrant.
EMERGENCY STEERING - PRIMARY STEERING FAILURE
If the primary steering fails it may be possible to steer the boat via the
autopilot controls.

DESCRIPTION
The RAM T1/T2 Hydraulic linear actuator combines a cylinder, pump,
motor, clutch and reservoir in a pre-filled, sealed unit. Designed to be
used on vessels fitted with mechanical primary steering that can be back
driven.
When the clutch is disengaged the cylinder is free and moves with the
primary steering. To operate the unit in autopilot mode the course computer energises the clutch solenoid coil and runs the bi-directional motor
to extend and retract the ram.
Internal relief valves protect the unit and its mountings from rudder
strikes, grounding etc.
