Maintenance and Troubleshooting

Air Flow Interlocks: The lamp fan vane switch is located within the lamp cooling compartment. The extractor vane switch is located just inside the top exhaust duct on the projector. Check and, if necessary, clean the switches to remove accumulated dust or dirt that could impede movement.

Within the exhaust duct connected at the top of the projector, adequate airflow must be maintained and routed away from the operating area surrounding the projector. Inspect regularly and confirm that:

•There are no obstructions or “kinks” within the ducting.

•All air intake areas of the projection head and ballast are unobstructed.

•Exhaust airflow at the top vent is at least 600 CFM. Make sure lamp wiring does not interfere with vane switch operation. Refer to Maintaining Proper Cooling on page 84.

Laminar Airflow Device (LAD): Whenever you check or replace the air filter on the side of the projector, also visually check the small square laminar airflow device just beyond the filter opening. The LAD should be nearly white in color. If it is very dark (rare), it may need to be replaced by a qualified service technician. Contact Runco or your dealer.

The SC-1 uses a xenon lamp to deliver its high brightness. The lamp should be replaced when it reaches the end of its life (typically 1000 hours), or sooner if a noticeable degradation in brightness occurs. When you replace a lamp, you should replace the air filter as well.

Keep track of the number of hours the lamp has been in use and be aware of any changes to brightness. These indicators will help you effectively maintain operation of the projector. To find out how long the currently-installed lamp has been in service, select Lamp Hours from the DHD Controller Installation menu (available by selecting Service -> Display Device -> Configure -> Installation, in sequence).

For lamp or filter replacement, please contact your nearest Runco authorized service center or Runco dealer. Do not attempt to replace the lamp yourself!

Xenon arc lamps are under high pressure and must be handled WARNING with great care at all times. Lamps may explode if dropped or

mishandled. Allow the lamp to cool completely before attempting to remove it.

Never open the lamp door unless you are wearing protective clothing. Recommended protective clothing includes — but may not be limited to — protective gloves, latex lab gloves, a double-layer 0.040” acetate face shield, and a quilted ballistic nylon jacket or welder’s jacket.

1.Turn off the projector. Allow the projector cooling fans to run for at least 10 minutes prior to disconnecting the power cord and removing the lamp assembly for replacement.

2.Disconnect the AC power cord from the projector.

3.Remove the screw holding the lamp/air filter cover in place. Then, lift the cover up and away from the projector (see Figure 3-6).

4.Turn the knob to open the inner lamp cooling compartment and reveal the cathode end (–) of the lamp (see Figure 3-6).
