Exhaust Duct And Lamp Fan Interlocks; Powering Up The Projector; If The Lamp Fails To Ignite - Christie CP2000-ZX Setup Manual

Section 3: Basic Operation
TIP: In the event coolant drips on any electronics or other nearby components, blot the affected area using
dust-free optical grade tissue. It is recommended you blot a few times, discard the tissue and use a new tissue to
blot the area again. Keep repeating this cycle until the coolant is cleaned up. Then lightly moisten a new tissue
with de-ionized water, blot the area again. Use a clean, dry tissue to dry the area off. Repeat the process of
using a clean tissue and blotting the area to successfully remove coolant spills.

3.2.4 Exhaust Duct and Lamp Fan Interlocks

CHECK: Every 6 months
The projector has two vane switches. One is located in the exhaust duct and the other is near the lamp fan.
1. Turn power to the projector ON, but do NOT turn lamp ON.
2. Turn off extractor fan.
3. Confirm that the extractor fan vane switch has indicated an extractor error message either through the CDP
or web user interface Status: Interlocks menu. Turn extractor fan back ON.
4. Block air intake at rear of the projector.
5. Confirm that the lamp fan vane switch has indicated a "blower error" either through the CDP or web user
interface Status: Interlocks menu. Clear air intake to correct the issue.
Maintain vane switches as described in
becomes significantly blocked, or if a fan fails, the projector's airflow sensor should trigger a shutdown before
the projector becomes overheated or unsafe. Regardless, check the airflow periodically.

Powering Up the Projector

This is a manual power-up procedure. Some cinema installations may include an automation system that
controls lamp ignition in conjunction with other theatre variables such as house lights, audio, and the start of
the feature from a digital media storage device/server. Warning! Do not attempt operation if the AC supply is
not within the specified voltage range.
1. Ensure the projector's wall circuit breaker is ON. The Ready status LED will illuminate a solid yellow.
2. On the CDP, press POWER ON to fully power up the projector in preparation for igniting the lamp, which
takes approximately 2 minutes. NOTE: If "lamp on" is selected while the projector is still in Standby
mode, the power will be turned on before the lamp.
3. On the CDP, press LAMP ON to ignite the lamp. The On status LED will illuminate green and begin
flashing slowly until the lamp is ignited, then it turns solid. The Ready status LED turns off when the lamp
is ON.

If the Lamp Fails to Ignite

• If a safety interlock switch is open (ie., lamp door is open), the lamp cannot be struck until the interlock
problem is resolved. The Error LED will illuminate red and flashing.
• If the lamp fails to ignite even though the interlock system is ok, the projector will automatically re-try
ignition using 100% of the maximum power acceptable for the installed lamp. If this re-try fails, a new
lamp is likely required.
