Camera Module Replacement - PTZ70

CAUTION !
Before performing any maintenance task, make sure camera system is turned off and be sure to
de-pressurize the camera unit via the Schrader valve (see page 12).
Follow these steps to replace the camera module in the event of camera failure:
• Remove the four Phillips screw from the front of the camera housing (fig. 59).
• Remove the four screws on the face of the camera housing.
• Remove the lock screw from the rear of the camera housing (fig. 60).
• Unthread the knurled ring on the back of the camera housing (fig. 61).
• Gently pull the front half of the housing away from the rear half. DO NOT TRY TO ROTATE THE
TWO HALVES. THEY ARE KEYED (fig. 62).
• Spread the wiring harness apart to clear pathway for the camera module. The camera
module is now loose and can be slid out of the housing.
• Disconnect the two white electrical connectors from the rear of the camera module. It is
recommended to pry gently and evenly with a flat-tipped screwdriver. Reconnect wiring
harnesses to the new camera module.
• Insert new camera module by aligning the word TOP on the camera module with the keyway
of the camera housing ensuring continuity among multiple camera systesm. The camera
module may be mounted in any of the four possible positions if a different orientation is
desired (fig. 68).

• Replace the four Phillips screws that hold the
camera.
• Arrange the wiring harness so they do not
get pinched during assembly.
• Align the keyway of the housing and slide
gently together. If the housings do not fully
seat together with gentle pressure, the cause
may be due to the wiring harness getting
pinched. Reopen the housing and check for
clearance (fig. 69).
• Replace the knurled ring and retaining screws.
• Pressure test camera housing. See "Pressure Testing" section on page 82.
