7 and 8 (Low Voltage Supply)
For operating external equipment. The current is supplied
by a secondary winding on the main motor, isolated from
the line-voltage power, and is available whenever the main
projector motor is running. Supply is 25.5 V, 500 mA
(1/2 A) maximum. Contact number 8 is common (return)
for the remote-control circuit. Contact number 7 is the
"hot" lead and is fused with a slow-blowing fuse. Replace-
ment requires disassembly of the projector by a qualified
technician
6 and 8 (Forward Tray Cycle)
Connects to the forward tray-advance circuitry in the
projector. These contacts are connected internally to the
remote-accessory receptacle and an electrical connection
made at either receptacle will result in a forward cycle.
2 and 8 (Reverse Tray Cycle)
Connects to the reverse tray-advance circuitry in the
projector. These contacts are connected internally to the
remote-accessory receptacle and an electrical connection
made at either receptacle will result in a reverse cycle.
Shell (Plug Ground)
If a plug with a conducting shell is used, it is connected
to the projector frame (chassis) through the special
application receptacle and to earth ground through the
projector's power cable.
