• The controller status will display "AIR
AVAILABLE".
2. At the same time, the service valve should
be opened and set to maintain the desired
operating pressure.
Fully opening the service valve can result in low
service pressure and an overflow condition. This
overflow condition can result in excessive oil
carry-over in addition to reduced air delivery as
the compressor slows to low idle rpm.

5.5 Shutdown procedure

WARNING
The E-Stop (emergency stop switch) should be
used only in the event of an emergency. Refrain
from using the E-Stop to shut the machine down
during normal operations or equipment damage
can occur. All usage of the E-Stop is logged in per-
manent memory for use by service technicians
when troubleshooting a machine. Non-emergency
use of E-Stop is considered equipment abuse and
could void the manufacturer's warranty.
1. Slowly close the service valve.
2. Place the <OFF/ON/START> switch in the
OFF position.
• The controller status will read "STOP INITI-
ATED" and the compressor will enter the
cooldown period.
3. The unit will continue to run at low idle rpm,
though it will not produce usable air. At the
end of the cool down cycle, the engine will
be shut down.
• The controller will stay powered up while
displaying a status of "MONITORING
PRESSURES".
• The controller will continue to monitor the
system pressures and will not power down
until all pressures drop below 2 psi
(0.14 bar). This final process may take 3 to
5 minutes. Operator interaction is not nec-
essary during this time as the controller will
automatically disconnect power to all sys-

tems so that the battery is not inadvertently
drained after shutdown.
Following engine shutdown, the exhaust after-
treatment will initiate a purge procedure to clear
remaining DEF from the lines. This is necessary
to prevent damage to the DEF injector from
flooding or freezing. A light is provided near the
battery disconnect to notify the user when the
purge cycle is active (see Figure 5-1 on page
50). Do not turn battery disconnect switch to off
when this lamp is lit or damage to the aftertreat-
ment could occur and an engine fault code may
be triggered.
4. Turn off the system power supply by turning
the battery disconnect switch to the OFF
position.
• For the location of the battery disconnect
switch, see Figure 2-1 on page 24 and Fig-
ure 5-1 on page 50.
It is a good practice to engage the battery dis-
connect after use. The engine and the compres-
sor controller systems continually draw power
after the controller is powered down. Over time,
this will deplete the batteries. If the batteries are
left on per application requirements, like remote
start applications, a battery maintainer should be
used to keep the batteries fully charged.
5. Vent all external pressure (pressure down-
stream of the machine) before disconnecting
any air tools, hoses, fittings, etc.
Pressure hazard
Failure to vent external pressure can result in
serious injury.
Vent all external pressure (pressure downstream
of the machine) before disconnecting any air
tools, hoses, fittings, etc. or performing any
maintenance procedures.
