Docking System
Target Docking Adapter Undocking Switch
Sends a command to the target vehicle command programmer and starts the mooring drive mechanism motor and lights the MSG ACPT light in the crew station. When the cone is unrigidized, the mooring drive motor stops and the latch mechanism actuator is energized to retract the latch hooks and release the spacecraft. The unlatch limit switch, within the latch mechanism, stops the actuator and starts a 30-second time delay relay.
