Introduction:
The controller performs the following functions:
- Compressor control
- Compressor protection
- Maintenance monitoring
- Automatic restart after supply interruption (optional).
Automatic control of the compressor
The controller maintains the outlet pressure within defined limits, commanding the load and unload operations of the compressor. Various
parameters are considered, among them are: the unload pressure, the load pressure, the minimum stop time and the maximum number of motor
starts.
Compressor protection
Shutdown
If outlet temperature of the element exceeds the programmed shut down level, the compressor will be stopped. This will be indicated on the display
(3). The compressor will also stop if a motor overload occurs.
