3. System Description
__________________
A. Cabin Attendant Work-Light The 115VAC from the busbar 210XP supplies the work lights through the circuit breaker 1LZ ATTN WORK LIGHT and the power control relay 2LZ. The work lights and the power units are installed in the overhead panels above the cabin attendant seats. The power units change 115VAC to 6VAC for the light operation. The membrane switch POWER ATTN on the forward attendant panel 120RH controls the power supply for the work lights.
Push the MAIN OFF membrane switch on the forward attendant panel 120RH to turn off the work lights together with all lights in other cabin systems.
The power unit is connected to a Decoder/Encoder Unit (DEU) of the Cabin Intercommunication Data System (CIDS). A test of the work lights is made from the CIDS system.

A. Cabin Attendant Work-Light Push the membrane switch POWER ATTN on the forward attendant panel 120RH to supply 28VDC to the relay 2LZ. The relay 2LZ energizes and completes the 115VAC supply to all the power units.
Push the work light membrane-switch to complete the 6VAC circuit for the work light. The related work light comes on. The integral light in the membrane switch comes on when the work light operates.
Push the work light membrane-switch again to turn off the related work light. Push the POWER ATTN membrane switch on the forward attendant panel 120RH again to turn off all the work lights. Push the MAIN OFF membrane switch on the forward attendant panel 120RH to turn off all the work lights together with the lights in other cabin systems.
