1. Most gas sensors have a finite life Sensor life is dependent upon its design internal chemistry and the operating environment With the exception of electro chemical Oxygen deficiency detectors electro chemical toxic and catalytic flammable gas sensors do not provide an indication of sensor failure Routine typically 6 monthly exposure to test calibration gas is necessary to verify gas sensor response and re validate the accuracy of gas concentration readings Routine service intervals may be extended if site specific data repeatedly shows no loss of sensitivity or accuracy of reading However routine service intervals should not exceed 12 months Service intervals should be shortened if site specific data shows a high loss of sensor sensitivity ECO is supplied with a software driven service flag defaulted to 6 months The default value can be reconfigured from 1 to 12 months in increments of one month via VSC The following checks and their outcomes will help determine whether the service intervals can be changed from the 6 month default e Remove and check the condition of the Filter assembly on the bottom of the Sensor cartridge Refer to page 95 for instructions on removing the filter cartridge assembly If the filter membranes are damaged replace the filter cartridge If not remove any dirt and dust build up If the buildup of contaminates on the filler membranes is excessive then consideration 92 Service and Maintenance 17
