7/124 - 10/104, 10/124 - 14/114, 14/84
The mode of the compressor can be changed between the Low
Pressure Mode and High Pressure Mode at any time when the
Start-Run button is activated. Engine speed will be lower at the High
Pressure Mode setting.
Operation - Loaded
Assume engine has been started and is running in the unload state at
idle speed. If there is air demand (pressure falls below the load point
pressure), compressor will load at idle speed by opening the inlet
valve. As air demand rises and falls, engine speed is controlled
between idle speed and full load speed to match the required flow while
maintaining load point pressure.
Operation - Unloaded
If there is no air demand at idle speed (pressure rises above the unload
point pressure), the compressor will unload by closing the inlet valve.
The compressor then runs at idle speed unloaded with no air delivery.
If air demand increases (pressure falls below the load point pressure),
the compressor reloads to meet the required air demand.
SHUTDOWN
1. Close the Service Valve.
2. Allow the engine to idle for 3 minutes to cool down.
3. Press the Red Stop Button.
4. Press the Main Power Button
when use of the compressor
is not needed.
Note:
Until Main Power Button is pressed, the gauges can be read and
the MidPort can be navigated using the UP, DOWN, and ENTER
Buttons.
5. If the Main Power Button is not pressed within 3 minutes (if ambient
temperature is above 45°F (7°C)) or 15 minutes if ambient
temperature is 45°F (7°C) or below of the keypad use the
compressor will automatically shut off.
If the battery needs to be disconnected, wait at least 70 seconds after
stopping the engine.
CAUTION: Failure to allow turbocharger cool down prior to stopping
can cause component damage.
NOTE: This compressor is equipped with a battery disconnect switch
which disconnects power for long term storage. The switch is located
on the fuel tank side.
NOTE: Do not use the battery disconnect switch for normal stopping.
Wait 1 minute after stopping engine before turning the battery
disconnect switch to the OFF position.
CAUTION: Use the Emergency Stop, if equipped, only for emergency
conditions. Do not use for normal stopping. Emergency Stop must be
reset before starting can be accomplished.
NOTE: Once the engine stops, the Automatic Blowdown Valve will
relieve pressure from the separator tank. If the Automatic Blowdown
Valve fails to operate, pressure must be relieved from the system by
means of the Manual Blowdown Valve.
CAUTION: Never allow the compressor to sit stopped with pressure
in the separator tank or piping. As a precaution, open the Service
Valve.
CAUTION: Unswitched battery power must be available to the ECM
for at least 70 seconds after the keyswitch is turned OFF. Failure to
do this will cause damage to the DEF pump.
