4. Control System Operation
4.1 General Information
The GASS-2040 system consists of an operator interface panel and a Koyo DL06 PLC which
serves a number of purposes. The PLC controls two or three PID temperature control loops. Two
PID loops are standard on the wall mounted version. Three PID loops are standard on the stack
mounted version which contains an additional PID loop for control of the probe filter.
In addition to controlling the temperature of the system, the PLC continually monitors the system
temperatures and will initiate an alarm if any of the temperatures deviate too far from their
respective set point temperatures. More about this can be found in the System Operation Monitor
section on page 15.
The PLC also controls timing of the optional heated probe filter blow back air and the coalescing
filter drain.
Clean display panel with soft cloth and mild detergent. Do not use chlorinate cleaners on stainless
steel housing.
