Power On
The Power Entry Control Module (PECM), in response to commands on internal bus, accepts
system primary power and provides switching and control of AC power for oven heaters and
other AC powered devices.
Sample Conditioning
Before being piped to the analyzer, the sample from the process is sent to a sample conditioner
system. The sample conditioner ensures that the process sample is compatible with the
requirements of the analyzer. That is, it assures that the phase, pressure, temperature and
flow rate to the analyzer are suitable, that the sample is filtered, that condensates are removed
and other treatments are carried out. The resultant conditioned sample is typically piped via
1/8-inch stainless steel tubing to the sample valve(s) located in the oven of the Maxum II.
