0.5 L Hydraulic pump spec discrepancy

[Chuck - Raymarine - Moderator]

Scoffer,

It is recommended that you review and execute the procedures for bleeding the hydraulic system as a first step in addressing the reported symptom. Raymarine's hydraulic pumps feature reversing DC motors. When one lead is connected to +12VDC and the other lead is connected to -12VDC, then the pump will drive in one direction. Reversing the leads will cause the pump to drive in the opposite direction. This simple test may be used to verify that the pump is moving the ram in each direction. Additionally, the Rudder Reference Transducer must be installed to view rudder position when the vessel is stationary or not underway and using the autopilot's Auto or Track features (the latter permits the autopilot to display a virtual rudder position based on vessel motion resulting from exercising drive actuator).
