Emergency hoist connections
Emergency hoist functionality is provided by the Hull Unit Control circuit board in the Motor Control Unit. We do not offer any optional products or kits to put this functionality to use. In order to use the emergency hoist functionality you will need to design your own interface and switch box.

You may need to make a hole in the Motor Control Unit cabinet to pull the cable through. Make sure that the hole does not have any effect on its splash proof integrity. Use a suitable grommet to protect the cable from the sharp edges of the hole.
How it works
+24 VDC is connected through a suggested "Hoist" switch (SW1) to pin 3. This will open the U7 optocoupler, and the "Inhibit" input on the microprocessor will go "low" forcing an immediate hoist pulse to the motor. Simultaneously, optocoupler U2 will be opened, and the suggested LED on pin 1 will be lit to indicate that the transducer is hoisted.
