8 PLUG & PLAY SMART SENSOR REPLACEMENT
A sensor will need to be replaced when it does not have enough sensitivity to
respond to a bump test or it repeatedly fails calibration. Similarly, the sensor
may need to be replaced if the application requirements change and a different
gas needs to be monitored.
A Plug & Play Smart Sensor Board is a sensor that is fastened to a small
circuit board with a memory chip that contains the sensor’s calibration and
configuration information. When a replacement smart sensor board or a brand
new gas smart sensor board is installed, the information it contains must be
written to the main circuit board.
8.1 How to Replace a New Smart Sensor Board
Smart board replacement sensors arrive pre-calibrated and factory configured.
After you physically replace the smart sensor board, you have to Read the
data stored in the new sensor board up to the main board, overwriting the
old sensor’s calibration information. After an appropriate warm up period (24
hours), you may want to do a bump test to confirm the response from the
sensor.
Power OFF the unit during the physical replacement of the sensor board.
The CO

smart sensor board is wide and plugs into two sockets. Unscrew the
smart sensor board you want to replace and gently pull it out of the sockets.
Insert the new smart sensor board and screw it in place. Complete the process
by loading the sensor (refer to Section
8.2 Read from Sensor
).
