Display box messages
Power ON, System OFF
Message/Problem
Possible Causes
Corrective Action
HYD OIL TOO COLD
The hydraulic oil
temperature is below
5oF (-15oC)
Pre-heat the hydraulic oil before running the
system.
No power to display
box
Fuse blown or bad
connection
Check components, replace fuse inside
PREDATAIR
ON button pressed/Initial start-up
Message/Problem
Possible Causes
Corrective Action
SOFT START XXXPSI
The system has
started, but the
compressor oil
temperature is still
cool.
The system is in “Unload” Mode, until the
compressor has come up to temperature
+122oF(50oC)
HYD OIL TOO COLD
The hydraulic oil is
below -13oF (-25oC).
The system is cautioning the operator to preheat the
hydraulic oil before starting the PTO system. The
Cold Climate Kit (A700146) can be installed to
speed warm-up once the hydraulic oil temperature
has reached –13oF(-25oC).
HYD OIL WARMING,
HYD XXXF/XXXC
The hydraulic oil is
between -13oF(-25oC)
and +5oF(-15oC)
Keep circulating hydraulic fluid until the system
warms sufficiently to start. If installed, the Cold
Climate Kit (A700146) will speed warm-up. The
Predatair won’t start until the hydraulic oil has
warmed to +5oF(- 15oC).
PREDATAIR does not
start when the ON
button is pressed.
Inappropriate
conditions for start-up.
Check display box for messages.
Hydraulic solenoid
failure.
. Check solenoid and connections.
Hydraulic motor or
compressor seized.
Check motor and compressor will roll-over.
Running
Message/Problem
Possible Causes
Corrective Action
STANDBY XXXPSI
The air pressure
stayed above the
restart pressure for
the duration of the
standby delay time.
The hydraulic solenoid is off, and the system is
monitoring air pressure and compressor and
hydraulic oil temperatures. If the air pressure
drops below the restart pressure, or the
compressor oil temperature drops below its
minimum, it will restart and rebuild air.
Air pressure won’t build
past approx. 40psi.
The system is in
SOFT START.
Wait for the compressor to warm up.
Unload solenoid on
inlet valve has failed
Check solenoid and wiring.

Check for air venting from blowdown cap while
running.
Compressor stalling/not
building air.
Hydraulic relief valve
lifting.
Check hydraulic pressure while running. Check
for other relief valves in system set too low.
Minimum setting 2800psi.
Hydraulic flow too
low.
Check for correct amount of hydraulic flow for
the desired CFM. Ensure that engine rpm is
being maintained when load is applied.
Unload Solenoid
Failure
Check solenoid and wiring.
General
Message/Problem
Possible Causes
Corrective Action
CHECK AIR
FILTER
Every 100 hrs, the system
reminds the operator to
check the air filter.
Check air filter and replace as needed.
Message will stop automatically after 6
hrs of operation.
HRS:XXXX:XX
500S
Every 500 hrs, the system
reminds the operator to
service the compressor.
Perform service as per Owner’s manual
using VMAC service kit. Once complete,
enter the Diagnostics Mode and clear
the service reminder. Refer to the
appropriate section in the Owner’s
manual.
OVER TEMP
COMP -
Compressor is
getting too hot and
is shutting down.
Low compressor oil.
Check oil level and fill as required.
Oil flow restricted.
Check oil filter for blockage. Remove
hoses and check for blockage. Check
cooler for blockage
Fan not operating.
Check connections. Check fan and relay
Insufficient air-flow or
ventilation.
Make sure the cooler and air filter are
not blocked. Open door if installed in a
cabinet. Improve ventilation. Move the
PREDATAIR out of the cabinet.
Failed temperature probe
or bad wiring connection.
Check the temperature probe and wiring
connections.

Temperature Sensor Trouble Shooting
Temporarily override the compressor temperature sensor:
This is only intended for use in an emergency to complete a job when servicing the unit
is not immediately possible. Running without a temperature sensor may result in failure
of the unit and/or damage to the hydraulic system, and is not recommended.
To temporarily disable the compressor temperature sensor, access the DIAGNOSTICS mode by
pressing and holding the OFF button. Once in DIAGNOSTIC mode allow system to scroll through
headings until the display shows: AIR TEMP SENSOR Press the ON button to access this
setting.
oPress and hold the ON button until NO AIR TEMP PROBE DIS? Appears on the screen
and then release the ON button.
oPress and hold the ON button again until TEMP PROBE DIS appears on the screen and
then RELEASE the ON button.
After the probe is disabled you need to back out of the DIAGNOSTIC screen by pressing both the
ON and OFF buttons simultaneously. You will need to do this twice to back right out to the main
screen.
To reset the PREDATAIR to default settings turn the power OFF then ON again. This will reset
the PREDATIAR temperature probes to ON.
