Maintenance and Troubleshooting

5.2

 

The high-intensity lamp and electronics rely on a variety of cooling components to reduce

Maintaining Proper

 

internal operating temperatures. Regular checking and maintenance of the entire cooling

Cooling

 

system is critical to prevent overheating and sudden projector failure, and helps to ensure

 

reliable operation of all projector components over time.

 

 

Ventilation

➤

Vents and louvers in the projector covers provide ventilation, both for intake

 

 

and exhaust. Never block or cover these openings. Do not install the projector

 

 

near a radiator or heat register, or within an enclosure.

Air Filter

➤

It is recommended that you replace the air filter (located on the lamp side of the projection

 

 

head) whenever you replace the lamp, or more often in dusty or dirty environments. A

 

 

clogged filter reduces air flow, and can lead to overheating and projector failure. Check

 

 

the air filter monthly. For detailed instructions, refer to Lamp and Filter Replacement on

 

 

page 87. It is also recommended that you visually check the laminar airflow device (LAD)

 

 

located nearby. The LAD should be nearly white or light grey in color.

Liquid Cooler ➤

The liquid cooler system circulates liquid to and from the DMDs in the projection head,

 

 

reducing their operating temperature to an acceptable level. Periodically check the coolant

 

 

level visible by removing the igniter grille (rear side grille adjacent to the side input panel).

 

 

The reservoir should be approximately half-full.

 

 

Note

A failure of the liquid cooling system will trigger an over-temperature

 

 

alarm condition, clearly indicated with status displays at the top of

 

 

 

the projector.

 

 

FILLING THE COOLER: The cooler should require filling only upon projector installation.

 

 

Fill with a 50/50 mix of distilled water and ethylene glycol. Top off as necessary. Do not

 

 

overfill.

 

 

 

WARNING

Whenever coolant has been added or replaced, check for a

 

 

possible airlock upon the next projector power-up.

Exhaust Duct and Lamp ➤

After installation, check and maintain operation of both vane switches — one in the

Fan Interlocks

 

exhaust duct and one near the lamp fan — as follows:

1. Turn the projector on (lamp is not needed).

2. Turn your extractor fan OFF.

3. Confirm that the LCD status display shows that the extractor fan vane switch has failed. Turn fan back ON to correct.

4. Block the air intake at the rear corner of the projection head (input side, next to the ballast control and safety interlock connectors; see Figure 2-1).

5. Confirm that the LCD status display shows that the lamp fan vane switch has failed. Clear air intake to correct.

6. Repeat this procedure every six months in permanent installations.

Maintain vane switches as described in the next section, Maintenance and Cleaning.
