GG-R
Maintenance
The GG-R 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
Expected sensor life of the GG-R is seven to ten years.
Failure of the infrared sensor happens normally when
the infrared optics reach the end of their useful life. If
this occurs, the sensor will produce a continuous fault
indication signal of 0.5 mA and the fault LED will be lit.
Field replacement of the sensor optics is not available
at this time. Contact Calibration Technologies for
sensor repair or replacement.
