COMPReSSOR COnTROLS

Direct online starting:
The compressor is equipped for Automatic Start & Stop
Control. When the receiver tank pressure reaches the
factory pre–set maximum pressure, the pressure switch
stops the unit. When the receiver tank pressure drops
below the factory pre–set minimum. The pressure
switch resets and restarts the unit.
The pressure switch cover can be removed by
unscrewing the two screws holding the cover.
Pressure switch adjustment:
The compressor package will cut–in and cut–out at
factory preset pressure settings. Adjust the pressure
switch only if absolutely necessary.
Adjustments are to be carried out only when the switch
is mounted, under pressure and voltage–free.
wARnInG
High voltage is present at the pressure switch
contacts when the power supply is connected.
Disconnect, lock and tag main power supply
before making adjustments.
wARnInG
Do not adjust the pressure switch to exceed the
maximum discharge pressure of the unit.
when replacing the pressure switch cover,
ensure the selector knob on the cover and
the lever on the switch are both in the "OFF"
position.
when the compressor is equipped with the
optional dryer and filters, the pressure switch
differential should be increased 10psi to account
for the added pressure drop of the filters and
dryer.

AUTOMATIC START & STOP COnTROL
Automatic Start & Stop Control is intended for
use when the motor will start no more than 6

When the receiver tank pressure reaches the factory
pre–set maximum pressure, the pressure switch stops
the unit. When the receiver tank pressure drops below
the factory pre–set minimum, the pressure switch resets
and restarts the unit.

DUAL COnTROL

Select either automatic start and stop control or
constant speed control by adjusting the knob on the
auxiliary valve. For automatic start and stop control, turn

than 10 minute intervals or runs more than 0 minutes
per hour. Turn the knob fully counterclockwise to run
the unit continually.
The auxilIary valve is factory pre–set at 5 psig
(0,3 bar) lower than the factory pressure switch
setting.
CAUTIOn
Running unloaded with no air demand, will
cause the unit to be shutoff by the pressure
switch.
