FLIGHT COMPARTMENT LIGHTS -TRAINING INFORMATION POINTS -P96 OVERHEAD DIMMER PANEL

Purpose
The P96 overhead dimmer panel gives a place to attach dimmer control units, relays and resistors related to the flight compartment lights.
Location
The P96 is in the ceiling, aft of the flight compartment door.
Physical Description
The P96 has relays in the upper left corner, resistors in the upper right corner and dimmer control units (DCU) on the rest of the panel. The relays and resistors are part of the lighting circuits that give floodlighting and dome lighting to the flight deck. Some of the floodlighting circuits (6v ac lights) use the dimmer control units. The overhead panel/instrument lighting circuits for the P5 and P11 panels also use these units.
Relays for these circuits are on the P96 overhead dimmer panel:
*
Dome lights dimmer

*
Standby (power) -dome and floodlight (4)

*
Storm -dome and floodlight (2).

Resistors for these circuits are on the P96 overhead dimmer panel:
* Standby dome lights
*
Captain’s panel floodlight (2)

*
Glareshield floodlight (2)

*
First officer’s floodlight (2)

*
Aisle stand floodlight.

Dimmer control units for these circuits are on the P96 overhead dimmer panel:
*
P11 overhead circuit breaker panel light (2)

*
P5 overhead instrument and panel light (2)

*
Captain’s floodlights

*
Glareshield floodlights

*
First officer’s floodlights.

Dimmer control units step-down 115v ac to 5-6v ac for the lights connected to them.
See the integral panel lights section for more information on dimmer control units (SECTION 33-13).

FLIGHT COMPARTMENT LIGHTS -TRAINING INFORMATION POINTS -FLIGHT COMPARTMENT DIMMERS AND RELAYS
Location
Dimmer control units (DCU) and relays related to these lights attach to the center aisle stand and the main instrument panels:
*
Captain’s instruments and panel lights

*
Glareshield instruments and panel lights

*
First officer’s instruments and panel lights

*
Aisle stand instruments and panel light.

The captain’s instrument and panel light DCUs are forward and outboard of the left outboard display unit on the P1. The first officer’s instruments and panel light DCUs are forward and outboard of the right outboard display unit on the P3. The other DCUs and relays are forward of the P9 forward aisle stand panel.
Dimmer control units filter and change the 115v ac to 5-6v ac for the lights that connect to them.
Training Information Point
All dimmer control units are the same. All units in the flight compartment connect to the master brightness control (MBC) card (not shown) in the P29 master dim and test card file.
See the integral panel lights section for more information about the dimmer control units (SECTION 33-13).
