Description of adsorption dryer solenoid valve control 

The inlet valves (Inlet A and B) switch every 120 seconds. 
The regeneration valves open variably based on the real load, e.g. if all motors are running, flushing 
is set to 110 seconds, while if one trio set is running, flushing is set to 55 seconds.
