Units with Diagnostic Lamps:
In a shutdown situation, the function of the panel
lamps is to indicate what specific failure caused the
unit to shut down.These lamps will remain illuminated
until the Power Switch is turned “OFF”.
UNITS WITH OPTIONAL DIAGNOSTICS LAMPS
NOTICE
None of the panel lamps should be glowing when ma-
chine is operating. If they are, shut unit down and refer
to Trouble Shooting Section.
STOPPING
Close air service valve.
Allow the unit to run at idle for 3 to 5 minutes to reduce
the engine temperatures.
Turn Power Switch to “OFF” position.
When the engine stops, automatic blowdown valve
should relieve system air pressure. If automatic blow-
down valve malfunction is suspected, open manual
blowdown valve.
Never allow unit to sit under pressure when engine is
not running.
WARNING
Since the service valve is closed, air downstream
of the valve may be trapped. A vent hole in the ser-
vice valve will slowly bleed air from the hose. Do
not disconnect hoses until all pressure has been
vented.
AUTOMATIC SHUTDOWN
This unit is protected with sensors (switches) for high
discharge air temperature, high engine coolant
temperature and low engine oil pressure.
Should any of three situations occur, the unit will stop.
Before restarting the unit, check these three areas for
excessive heat and fluid level. Other possible causes
are listed on the Trouble Shooting Chart.
All units in this family of machines are protected by
sensors or switches at the following locations:
(1) Low engine oil pressure, in the engine.
(2) High engine coolant temperature, in the engine.
High Discharge AIR Temperature
(3) At the airend outlet.
(4) In separator tank.
NOTICE
Do NOT wire around or bypass a shutdown
sensor or switch.
DANGER
Even after pressure is relieved from the receiver--
separator system, any air supply line from the
compressor to a tool or a machine could remain
under pressure and cause very serious personal
injury or death. After the compressor stops, care-
fully open a valve at any tool or machine to ex-
haust the pressure in any line prior to removal or
servicing.
