COMPRESSOR OPERATION

6.1 INTRODUCTION
While Sullair has built into the LS-32 Series pack-
age a comprehensive array of controls and indica-
tors to assure its proper operation, the user should
recognize and interpret readings which call for
service or indicate the onset of a malfunction.
Before starting the unit, the user should become
familiar with the controls and indicators-their pur-
pose, location, and use.
6.2 PURPOSE OF CONTROLS
All Supervisor Controller related functions and indi-
cators are presented in Section 5.2, so please refer
to that section for your information. Additional indi-
cators and functions included in the package are as
follows:
EMERGENCY STOP SWITCH
THERMAL O/L RESET
SULLICON ACTUATOR
SPIRAL VALVE
PRESSURE REGULATOR (SULLICON)
PRESSURE REGULATOR (WITH
SPIRAL VALVE)
SOLENOID VALVE #1
SOLENOID VALVE #2
DISCHARGE CHECK VALVE
Pushing in this switch, found adjacent to the Supervisor, cuts
all AC outputs from the Supervisor and de-energizes the
starter. A fault message (E STOP) is displayed by the
Supervisor until the button is pulled out and the “O” pad is
depressed.
Momentarily pushing this button, found on the starter’s ther-
mal overload element housing, re-closes the starter’s con-
tacts after a current overload takes place. Please be aware
that the elements must be allowed to cool sufficiently before
resetting.
Actuates the inlet butterfly valve which throttles the air flow to
the compressor inlet, in order to match air supply to the
demand.
Internally bypasses and controls the air flow capacity of the
compressor, in order to match air supply to the demand.
Opens a pressure line between the sump and Sullicon
Control allowing the Sullicon Control to regulate air delivery
according to the air demand.
Opens a pressure line between the service line and the spiral
valve actuator allowing the spiral valve to regulate air delivery
according to air demand.
Electrically actuated, 3-way valve which controls the flow of
pneumatic logic signals. Used throughout package to:
·
Open the blowdown valve.
·
Load the Sullicon device/close the inlet butterfly valve during
shutdown operation.
·
Open the spiral valve.
Opens when the compressor starts; closes when the com-
pressor is shut off. This prevents any air system loss and de-
pressurizes the controls when the compressor is shut off.
Blocks the reverse flow of air/fluid through the compressor
unit during shutdown.
