61-1000RK-05 Combustible Gas Detector• 12
8. Turn on power to the controller.
9. Turn on the controller.
10. Secure the junction box cover to the junction box.
11. Calibrate the replacement detector as described in the Calibration section of this
manual.
Calibration
This section describes how to calibrate the combustible gas detector. It includes
procedures to assemble the calibration kit, set the zero reading, set the response reading
and return to normal operation.
WARNING: The controller is not an active gas monitoring device during the calibration
procedure.
Assembling the Calibration Kit
1. Screw the calibration cup onto the bottom of the detector.
2. Use the sample tubing to connect the regulator to the calibration cup.
NOTE
: Do not screw the regulator into the calibration cylinder at this time.
3. Place the controller into its calibration program or disable external alarms.
NOTE:
Calibrating the combustible detector may cause alarms. Be sure to put the
controller into its calibration program or disable external alarms before
continuing.
Setting the Zero Reading
CAUTION:
If you suspect the monitoring environment is not free of combustible vapors, use the
calibration kit and a zero air calibration cylinder to introduce “fresh air” to the
detector and verify an accurate zero setting
1. Verify that the detector is in a fresh air environment.
2. Follow the directions in the controller’s instruction manual for setting the zero
reading.
Setting the Response Reading
1. Follow the directions in the controller’s instruction manual for setting the response
reading (span).
2. When the directions call for exposing the detector to gas, screw the regulator into the
cylinder and allow the gas to flow to the detector until the reading at the controller
stabilizes, approximately 2 minutes, before continuing with the directions.
3. After setting the response reading, unscrew the regulator from the cylinder and
remove the calibration cup from the detector.
