1.5 Setting pressure
Compressor control/speed is achieved using a pressure
transducer signal to the controller and/or inverter PID to
match output to system demand.
In the [CONTROL MENU] menu you have to set the
maximum pressure CUT-OUT POINT and the minimum
pressure CUT-IN POINT or TARGET PRESSURE.
In the range between the CUT-IN POINT or TARGET
PRESSURE and CUT-OUT POINT the output or speed of
the compressor is controlled or regulated to match the
compressed air requirement.
Example:
CUT-OUT POINT 8.5 bar (123 psi)
CUT-IN POINT (SS) 7.5 bar (109 psi)
TARGET PRESSURE (RS) 8.0 bar (116 psi)
