both the enclosure rear cover and body.
Instructions for use

WARNING
Explosion hazard!
Do not use the flame detector if the rear enclosure cover cannot be screwed
onto the enclosure body by five or more full turns. The detector has insufficient
explosion protection (the flame path is too short) and using it in an explosive
atmosphere may lead to an explosion.
► If so, return the detector to Dräger for investigation/repair.
8. Fully screw the rear enclosure cover to the enclosure body. Ensure that the
O-ring is beneath the cover and that the set screw will not interfere with or
be screwed into the threads of the flame path or the O-ring. Secure the rear
enclosure cover in place with the set screw.
Reversal of polarity across terminals 1 & 2 enables RS485
communication on terminals 3 & 4. The RS485 signal can be used to
communicate with the flame detector and configure the device.

Commissioning
1. Detectors that require maintenance / commissioning should be taken offline
and inhibited. Detectors which require to be opened will need to be isolated
electrically.
2. Ensure that the detector mounting arrangements are secure and
undamaged.
3. Ensure that the detector enclosure is intact and undamaged.
4. Ensure that all associated cables and glands are correctly made up, secure
and undamaged.
5. Clean the enclosure faceplate (outside) with a mild detergent solution and a
soft cloth until the window is clear of all contamination. Wash the window
thoroughly with clean water and dry with a clean lint-free cloth or tissue.
Cleaning in the faceplate must be carried out prior to initial powering of
the device. The flame detector will carry out an automatic Optical Test
Calibration upon power up.
6. Switch on the flame detector.
7. Ensure system inhibits are applied to the alarm output of the detector.
