Auto-test Generator:
A major expense in gas detection systems is the cost of regular testing to ensure that sensors are responding. This requires a technician to inspect sensors weekly and apply a small amount of gas manually to check response. ATI has developed a unique system to reduce this maintenance requirement.
Available on most ATI digital sensor/transmitters is an option called “Auto-Test.” This option consists of an electrochemical gas generator closely coupled to the sensor. Every 24 hours, the receiver automatically activates the generator, producing a small amount of gas that diffuses into the sensor, just as it would if a gas leak occurred. The microcomputer in the receiver analyzes the output of the transmitter to determine that the sensor is responding normally. When proper sensor response is detected, the generator is turned off and the system goes back to normal operation. If no sensor response is detected, the TROUBLE light on the receiver will flash and the trouble relay will activate. During testing, alarm relays are inhibited so that external alarms are not activated.
The Auto-Test feature ensures that each sensor is regularly tested with gas. Premature sensor failure or blockage of the sensor membrane is quickly detected. In addition, self-testing will alert maintenance personnel when a sensor has reached the end of its useful life. Since sensors normally last anywhere from 12 months to over 3 years, this feature allows users to determine when sensor replacement is needed.
The Auto-test option requires a gas generator, which must be compatible with the installed sensor’s gas type, and full-scale range. Table below lists gas compatible generators and sensors.
