11. Reinstall the junction box cover.
Start Up
This section describes procedures to start up the toxic 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 or plug in the incoming power, then turn on the controller.
4.
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 Reading”.
Setting the Zero (Fresh Air) Reading
CAUTION:
If you suspect the presence of the target gas in the monitoring environment, use the
calibration kit and a zero air calibration cylinder to introduce “fresh air” to the toxic
detector and verify an accurate zero setting. See “Calibration” on page 12 for
instructions to introduce zero air to the detector.
1.
Verify that the detector is in a fresh air environment (environment known to be free of
toxic and combustible gases, and of normal oxygen content, 20.9%).
2.
Verify a reading of 0 ppm at the controller.
If the display reading is 0 ppm, start up is complete. The toxic detector is in normal
operation. If the display reading is not 0 ppm, continue with step 3.
3.
Perform a zero (fresh air) adjustment operation at the controller. See the controller
operator’s manual for instructions.
Maintenance
This section describes maintenance procedures. It includes preventive maintenance,
troubleshooting, and component replacement procedures.
Preventive Maintenance
This section describes a preventive maintenance schedule to ensure the optimum
performance of the toxic detector. It includes daily, monthly, and quarterly procedures.
Daily
Verify a display reading of 0 ppm at the controller. Investigate significant changes in the
display reading.
Monthly
This procedure describes a test to verify that the toxic detector responds properly to the
target gas. It describes the test using a calibration kit that includes a calibration cup,
