Features and Functions
8-Pin Receptacle
The 8-pin receptacle provides access to the circuitry of
the projector and allows for additional external control and
programming capability. Functions include forward and
reverse slide change, sensing of the zero tray position
when the shutter is closed and electrical grounding. 8-
contact or “DIN-type” 3 and 5 contact plugs may be used.
22.5 volts of isolated power is available.
Warning
All circuits connected electrically to the projector through
this receptacle must have a rating of no more than 30 V
(rms) and must comply with Underwriters Laboratories,
Inc. low voltage, limited-energy circuit requirements.
8-Pin Contact Data
1 and 3 (Zero Position Switch)
Connects to an internal single-pole, single-throw, normally
open switch. Contacts are closed when the projector
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 and 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.
