For stepless (infinitely variable) capacity control of air
compressors: suction control valves, bypass valves, bleed
valves and engine speed controllers are governed by the
signal from the proportional controller.
Operation:
Controllers LHP-CP2, LHP-PRD08020-A, LHP-PRD08040-A are positive acting. Within the
control band (see diagram 2) they give a proportionally rising signal at (A) on increasing
pressure at (P).
Adjustment:
The set point is adjusted by turning the hand wheel.
* To a higher pressure: clockwise.
* To a lower pressure: counterclockwise.
