9.
If using shielded cable, connect the cable’s drain wire to an available chassis ground at
the controller. RKI controllers typically have a ground stud that is a convenient
grounding location.
10. Reinstall the junction box cover.
Start Up
This section describes procedures to start up the CO detector and place the detector into
normal operation.
Introducing Incoming Power
1.
Complete the installation procedures described earlier in this manual.
2.
Verify that the power wiring to the controller is correct and secure. Refer to the
controller operator’s manual.
3.
Turn on power to the controller.
4.
Turn on the controller.
5.
Verify that the controller is on and operating properly. Refer to the controller
operator’s manual.
CAUTION:
Allow the detector to warm up for 5 minutes before you continue with the next
section, “Setting the Zero (Fresh Air) Reading”.
Setting the Zero (Fresh Air) Reading
WARNING: If the detector installation is explosion proof, do not remove the detector
housing cap or junction box cover while the circuits are energized unless the
area is determined to be non-hazardous. Keep the detector housing cap and
junction box cover tightly closed during operation.
CAUTION: If you suspect the presence of CO in the monitoring environment, use the calibration
kit and a zero air calibration cylinder to introduce “fresh air” to the CO detector and
verify an accurate zero setting. See “Calibration” on page 12 for instructions to
introduce zero air to the CO detector.
1.
Verify that the detector is in a fresh air environment (environment known to be free of
carbon monoxide, other toxic and combustible gases, and of normal oxygen content,
20.9%).
2.
Verify a reading of 0 ppm CO at the controller.
If the display reading is 0 ppm CO, start up is complete. The detector is in normal
operation. If the display reading is not 0 ppm CO, continue with step 3.
3.
Perform a zeroing operation at the controller. See the controller operator’s manual for
directions.
