Seakeeper 35 / 30HD Operation Manual (90269-7)
Electronic Control Module
The Electronic Control Module (ECM) monitors all the system sensors and automatically regulates operation of the Seakeeper.
The controller commands the motor speed and regulates the Seakeeper’s precession rate and gimbal angle. This is accomplished by commands to a high response flow control valve in the hydraulic brake circuit that increases or decreases the brake pressure.
