7.8 SENSOR MODULE REPLACEMENT

The module can be replaced by first disconnecting the electronic connectors from

the sensor PCA that run to J13 (Bench Supply) and J10 (Bench Serial Interface) on

the Mainboard, and by disconnecting the pneumatic tubing at the sample filter and

at the input to the scrubber. Then remove the four large socket head screws (Figure

7-5) that hold the mounting bracket in place. Do the reverse to install the

replacement module.
