CONVERTING A C7050 FLAME
DETECTOR TO A MODEL X7050
CAMERA
The Model X7050 Camera module can be installed in
place of the UV tube module in an existing C7050 Flame
Detector to provide basic visual monitoring capability.
CAUTION
Under no circumstances can 290 Vdc be applied
to the camera.
1. Provide the correct wiring to the C7050/X7050
location as described in “Wire Size and Type” in the
Installation section of this manual.
CAUTION
Power must not be applied to the device while
opening the housing or while plugging in or
removing the module.
2. Disassemble the enclosure by turning the housing
cover counterclockwise. See Figure 8 for an
illustration of the xWatch Camera assembly.
3. Remove the existing UV module from the C7050
detector.
4. Disconnect the existing wiring at the controller.
Connect the grounding strap between the new
index pin and the terminal mounting screw per the
instructions. See Figure 9.
IMPORTANT
Do not test any wiring connected to the xWatch
Camera with a meg-ohmmeter. Disconnect wiring
at the camera before checking system wiring for
continuity.
5. Check all field wiring to be sure that the proper
connections have been made.
6. Using the index pin as a guide, install the xWatch
Camera module on the terminal block.
7. Re-assemble the device housing.
8. Make the final sighting adjustments and ensure that
the mounting bracket hardware is tight.
