Section 4: Operation - Sullair 185Tier 3 Kubota User Manual

185 T3 Kubota User Manual
4.1 General
While Sullair has built into this compressor a complete
set of controls and indicators that allow the operator to
control and monitor the compressor's operation and per-
formance. Operators should learn to recognize indica-
tions which identify a service requirement or conditions
that could lead to (or show) a (current) malfunction.
Before starting the compressor, read this section thor-
oughly to gain familiarity with the controls and indicators
– their function and location.
4.2 Purpose of controls
Engine switch
Press this switch to the ON (ignition) position to energize
the electrical system of the compressor. Press the switch
to the START position to momentarily engage the starter
and start the compressor. Press the switch to the OFF
position to shut the compressor down. This switch is
located on the instrument panel.
Cold weather starting aid button
Push this button, prior to compressor start-up, to allow
the engine to pre-heat for easier starting.
Hourmeter
Indicates the accumulated hours of operation. Useful for
planning and logging service schedules.
Air pressure gauge
Continuously monitors the pressure inside the receiver
tank at various load and unload conditions.
Fluid sight level glass
Indicates the fluid level in the receiver tank. Proper level
is marked halfway up the sight glass. Check the level
when the compressor is shutdown and on level ground.
Section 4
Operation
02250223-054 R01
Subject to EAR, ECCN EAR99 and related export control restrictions.
Compressor discharge temperature switch
Opens the electrical circuit to shut down the compressor
when the discharge temperature reaches a specific value
(see Table 3-2: Compressor specifications on page 29).
Thermal valve
Functions as a temperature regulator by directing the
compressor fluid either to the cooler or to the compressor
unit.
Minimum pressure device
Maintains the minimum of 80 psig (5.6 bar) in the com-
pressor sump.
Pressure relief valve
Vents sump pressure to the atmosphere if pressure
inside the sump exceeds 200 psig (13.8 bar).
Air inlet valve
Regulates the amount of air allowed to enter the air com-
pressor inlet. Regulation is determined by a signal from
the pressure regulator(s).
Pressure regulator
Allows the pressure signal to reach the engine speed
control and the air inlet valve to control air delivery
according to demand.
Shutdown System/Annunciator Module (SSAM)
Monitors the compressor safety system for conditions
requiring shutdown. The annunciator on the instrument
control will flash the applicable shutdown code.
Blowdown valve
Vents sump pressure to the atmosphere at shutdown.
Idle warm-up control
Keeps the compressor inlet valve closed for reduced
compressor load at start-up. When the compressor is
warmed-up, the handle is turned from the START to the
RUN position for full operation.
