Description

 

 

 

1 & 3

Zero-Position Switch

Connects to an internal single-pole single-throw normally

 

(Models A and E Plus)

open switch. Contacts are closed when the slide tray is at any

 

 

position other than zero. These leads connect only to the

 

 

switch terminals. Do not exceed a switching load of 1 A at

 

 

30 V ac.

 

 

 

4 & 5

Shutter Switch

Connects to an internal single-pole single-throw normally

 

 

closed switch. Contacts are open when a slide is in the

 

 

projector gate and the shutter is open. These leads connect

 

 

only to the switch terminals. Do not exceed a switching load

 

 

of 1 A at 30 V ac.

 

 

 

7 & 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. (Replacement requires

 

 

disassembly of the projector by a qualified technician.)

 

 

 

6 & 8

Forward Tray

Connects to the forward tray-advance circuitry in the

 

 

projector. These contacts are connected internally to the

 

 

remote-control receptacle and an electrical connection made

 

 

at either receptacle will result in a forward cycle.

 

 

 

2 & 8

Reverse Tray Cycle

Connects to the reverse tray-advance circuitry in the

 

 

projector. These contacts are connected internally to the

 

 

remote-control 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.
