| Contacts | Function | Description |
|---|---|---|
| 1 & 3 | Zero-Position Switch (Models A and E Plus) | Connects to an internal single-pole single-throw normally 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. |
