CAUTION
Ether is an extremely volatile, high flammable
gas. Use Sparingly! If too much is injected, the
uncontrolled explosion may result in costly
damage to the engine.
4. In cold weather, as required, press the
ETHER INJECT button once or twice only
while the engine is cranking. This injects a
measured amount of ETHER to the engine.
5. Following a successful start, the engine will
accelerate to idle speed of 1200 RPM for
warm--up. Compressor discharge pressure
will be maintained at 60 psi during warm--up.
6. Press the LOAD button. The engine will
increase speed up to 1800 rpm until the
pressure reaches the desired set point.
NORMAL OPERATION
The Operator may observe and monitor operating
parameters using the gages on the panel. In the event
the machine controller detects a parameter outside
normal operating limits, the unit will shutdown.
In the event the machine controller detects a
parameter at a dangerously high or low level, the
machine will be automatically be stopped with the
cause of the SHUTDOWN shown on the diagnostic
lights.
Delivered air volume at set point pressure is
accomplished by two methods:
1). The compressor is loaded (inlet valve fully open or
modulated partially open), or unloaded (inlet valve
fully closed).
2) Engine speed varies between 1200 RPM and 1800
RPM while compressor is loaded to match the
required volume flow.
Operation -- Loaded
Assume engine has been started and is running in the
unload state at 1200 RPM. If there is air demand
(pressure falls below the load point pressure),
compressor will load at 1200 RPM by opening the inlet
valve. As air demand rises and falls, engine speed is
controlled between 1200 RPM and 1800 RPM to
match the required flow while maintaining rated
pressure.
Operation -- Unloaded
If there is no air demand at 1200 RPM (Pressure rises
above the unload point prssure), the compressor will
unload by closing the inlet valve. The unit then runs at
1200 RPM unloaded with no air delivery. If air demand
increases (pressure falls to below the load point
pressure), the compressor reloads to meet the
required air demand.
STOPPING
S
Close air service valve(s).
S
Allow the unit to run at “no load” for 3 to 5 minutes
to reduce the engine temperatures.
S
Turn the keyswitch to the “OFF” position.
NOTICE
Once the engine stops, the automatic blowdown
valve will continue to relieve all pressure from
the check valve to discharge valve piping.
NOTICE
Failure to allow turbo cool down prior to
stopping can cause turbocharger damage.
WARNING
Even after pressure is relieved from the piping
system, any air supply line from the compressor
to a tool or machine could remain under
pressure and cause serious personal injury or
death. After the compressor stops, carefully
open a valve at any tool or machine to exhaust
the pressure in any line prior to removal or
servicing.
CAUTION
Never allow the unit to sit stopped with pressure
in the receiver--separator system. As a
precaution, open the service valve.
