Abstract
The shutter motor keeps tripping out, and causing the dome to become stuck open. The dome and shutter motors were swapped over to eliminate a fault with the motor. It was discovered that there was no keyway on the shutter motor shaft which was allowing the motor to slip. A second fault was found on one of the SSR relays in the relay box. A keyway was installed, and the faulty SSR bridged out. The shutter now operates correctly. Additional work was done on the weather arm, replacing the rain detector and repairing the anemometer.
