GG-CO2
Maintenance
The GG-CO2 was designed for long life and minimal
maintenance. For proper operation it is essential
that the test and calibration schedule be adhered to.
Calibration Technologies recommends the following
maintenance schedule
Maintenance Guidelines:
• The sensor is shipped with a factory calibration.
Sensor should be calibrated 6 months from
purchase date.
• Calibrate the detector at least once every 6 months.
•
Calibration should be performed with certified
calibration gas. Calibration kits and replacement
cylinders are available from Calibration
Technologies.
• All tests and calibrations must be logged.
• Always disconnect power at the controller before
performing any wiring at the sensor.
Sensor Life:
Typical sensor life of the GG-CO2 is five
to seven years. Failure of the infrared sensor happens
normally when the infrared source opens or breaks,
similar to an incandescent light bulb filament. If this
occurs, the sensor will produce a continuous fault
indication signal of 0.5 mA and the fault LED will be
lit. Contact Calibration Technologies for a sensor
replacement.
