Page 27: Sequence Of Operations
Belimo Gas Monitors 4.8 Sequence of Operations Gas monitors and communication modules are preloaded with default programmable settings for normal operation and can be changed by the user at any time via the key pad. On power-up the display will show the firmware version number and the warm up timer will count down (programmable setting 52, default 1 minute). - Page 28 Belimo Gas Monitors If the temperature exceeds the high temperature alarm limit (programmable setting 51), relay 1 will activate, the alarm 1 red LED will turn on and the alarm 1 transmit message will be sent via the CAN bus network to other gas monitors and communication modules.

Page 33: Maintenance
Certified gas bottles of ± 2% accuracy (or better) should be used for both the zero and the span point. In conjunction with certified gas bottles, it is recommended to use the Belimo calibration kit (A-22G-A22) that includes a regulator (0.5 LPM), tube, and cap to adjust the sensitivity of the sensor module due to normal aging. -
Page 34: Calibration Procedure: Electro-Chemical And Catalytic Sensor Modules
To calibrate gas monitors it is important to keep the front cover on, and make sure it is securely screwed to the base. When not using the Belimo calibration cap, it is important that the calibration cap you are using has a small outlet hole, otherwise the pressure will increase and distort the reading. -

While at SAS (sensor A span) or SBS (sensor B span) flood the certified span gas over the sensor module. To do this, connect the span gas bottle to the Belimo regulator, and insert the calibration cap onto the sensor hole located on the gas monitor front cover. Flood the sensor with the span gas at a flow rate of 0.5 LPM for 90 seconds or until the... - Page 36 When not using the Belimo calibration cap, it is important that the calibration cap you are using has a small outlet hole, otherwise the pressure will increase and distort the reading.
