DESCRIPTION
RAM T3 Hydraulic Steering Systems combine a hydraulic cylinder with
clutch, reversing pump and reservoir in a compact installation.
A solenoid clutch is engaged to extend or retract the rod. The cylinder
and its mounting are protected by integral relief valves. Overall adjustment is incorporated into the stroke of the cylinder. Nominal cylinder
size and pump flow are indicated on the rating plate. Check the voltage
shown is correct for the output of your autopilot.
Please do not disconnect any of the hoses, the system has been filled
and tested prior to shipment.
Ensure you read and understand the special reservoir instructions on
page 10 before commencing installation.
LOCATION
For marine applications these systems are designed for 'under deck'
installations only.
Excessive temperature, vibration and fumes in the atmosphere can
drastically reduce motor life.
It must be mounted securely and on a surface that is able to withstand
the high thrusts generated.
As in common with other electrical equipment contact with water and
excessive humidity must be avoided.
Any attitude of mounting may be used but horizontal is preferred. Refer
to the installation and technical data pages for further information.
The reservoir must be located in an area that is not subject to extremes
of temperature and humidity and away from refrigeration compressors
and air-conditioning plant.
