SETTING THE PRESSURE TRANSDUCER (PT)
TO CHECK THE MAXIMUM DISCHARGE PRESSURE
(Pressure transducer upper trip point)
Slowly close the isolation valve located adjacent to the compressor.
Observe the rise in pressure and ensure that the pressure transducer
opens at the correct Maximum discharge pressure.
The maximum discharge pressure is shown on the machine data plate.
DO NOT exceed these figures.
The compressor will stop once the system pressure rises to this
pressure.
TO CHECK THE TARGET PRESSURE
Observe the line pressure fall and note the point at which the
pressure transducer closes (and starts the compressor).
TO ADJUST THE TARGET PRESSURE
Remove the airend enclosure panel and locate the POT. Turn the POT
adjuster knob clockwise to increase the set point or anti clockwise to
decrease it.
TO CONVERT UNIT FROM VARIABLE SPEED MODE TO FIXED
SPEED MODE.
Remove the airend enclosure panel and locate the toggle switch. Since
the switch is a 2 position , simply toggle between position to vary the
mode.
