C. System Operation

(1) Baggage compartment
A 28 V dc supply goes through a switch to operate the time limit relay for the lights in the main baggage compartment. The door of the main baggage compartment operates micro-switches which connect grounds to the time limit relay. When the door is opened and the switch is set to on, the lights come on. The time limit relays set the lights to off after five minutes.

(2) Service compartment
A 28 V dc supply goes from the refuel panel to the refuel panel light. When the refuel panel is set to on, the refuel panel light comes on.
