Christie Digital Systems CX50, CX67, CX60 NOTE Do not ceiling mount this projector, Operation

Section 3: Operation

Electrical Module (EM) ' The EM is the main control unit of the projector. It is mounted independently from the PHM to the mounting tray. It is the module where all source connections are made and where the main power switch is located.

The EM contains the majority of PCB’s, such as the Control PCB, BNC Input PCB, Video Input PCB and Control RS-232C PCB. In general, these boards are responsible for the video processing and communication requirements of the projector. It also houses the IR sensor PCB and the Power PCB.

Located on the input side of the EM are 3 LEDs. These LEDs will illuminate in patterns, which represent the status of the projector and/or any error conditions that may be present. Refer to Table 3.1. for the status of the LEDs during normal operation and at the end of this section for system error codes.

6-Axis Adjuster ' You can correct the geometry of a displayed image by adjusting the uniquely designed 6-axis adjustment mechanism. The PHM can be mounted to this

mechanism in a lens horizontal (0 degree) or a lens vertical (90 degree) orientation. The mechanism, which is manually adjusted, can be adjusted to correct any geometric misalignment between the projector and the screen. Typically, this mechanism only requires adjustment during the initial setup of the projector. Adjustments can be locked in place to avoid tampering and the need for re-adjustment.

The 6-axis adjuster and EM are mounted to a welded frame called the mounting tray. The purpose of this tray is to keep the modules together and makes the installation process easy. It can be installed on any sturdy, flat surface as long as all four mounting points are used to secure it in place.

Refer to the separate Installation Guide provided in the User’s Kit for installation instructions and how to adjust the 6-axis adjuster.

NOTE: Do not ceiling mount this projector.
