TWO AIR FLOW SWITCHES, mounted to the exhaust duct and the blower intake,
will prevent ignition of the lamp if the top blower is not operating, or the exhaust air flow is inad-
equate. The eight-inch lamphouse exhaust stack connects to an externally installed exhaust system.
The exhaust system must be capable of removing 700 cubic feet per minute (c.f.m.) of free air from the
lamphouse, as measured at the lamphouse exhaust outlet.
THE LAMPHOUSE has an interlock switch on the side access door and one under the
igniter cover on the top of the lamphouse. Opening the side door or removing the plastic igniter cover
will open the AC control circuit and prevent operation of the xenon lamp. The lamphouse door has a
viewing port to permit observation of the xenon arc.
THE IGNITER is equipped with an emergency ignition switch, located beneath the
plug button on the igniter access panel on the top of the lamphouse.
THE "MODE" rocker type switch on the rear of the lamphouse provides the means of
operating the equipment from a remote AUTO system, or when placed in the "MAN." position, from
the lamphouse.
THE LAMP "ON - OFF" SWITCH on the lamphouse instrument panel is used for bulb
ignition when the MODE switch is in the "MAN." position. For AUTO operation, the LAMP switch
remains in the "ON" position.
THE LAMPHOUSE DOUSER is provided to permit shutting off the light to the pro-
jector at changeover. The lamp should not be operated for any extended time with the douser closed.
The small intense spot of light on the douser plate may cause deterioration of the plate. An Electric
Douser Kit, connected to the projector motor, is available as an option. This option automatically
closes the douser when the projector motor is switched OFF.
THE ULTRA 80 is not designed for use with 35mm projection. The highly intense
radiant energy generated by high wattage xenon bulbs will damage 35mm prints.
