Power ON, System OFF
Message/Problem
Possible Causes
Corrective Action
HYD OIL TOO COLD
The hydraulic oil
temperature is below
5
o
F (-15
o
C)
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
+122
o
F(50
o
C)
HYD OIL TOO COLD
The hydraulic oil is
below -13
o
F (-25
o
C).
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
–13
o
F(-25
o
C).
HYD OIL WARMING,
HYD XXXF/XXXC
The hydraulic oil is
between -13
o
F(-25
o
C)
and +5
o
F(-15
o
C)
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 +5
o
F(- 15
o
C).
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 pressur
e 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.
