TROUBLESHOOTING TABLES
SYMPTOM
ITEM CHECK
CORRECTIVE MEASURE
PHX-200 WILL
NOT ARM
System Supply Valve V1
not open
Open System Supply Valve {yellow handle)
E-STOP Button is depressed
Pull E-STOP Button out to enable ARM System
Safety Screen is not properly
installed
Make sure Safety Screen fully engages interlock
valve V2 when installed
Trigger lines improperly
connected
Check trigger lines at the machine and at the gun.
Inspect entire length of Large
Trigger Line for holes or cuts
Replace or repair Trigger Line as required.
Loose or kinked tubing in
Control Panel
Check for loose or kinked tubing behind
Control Panel and E-STOP button, especially
the Red tubes. All Red tubing is directly related
to the ARM system.
Control Air Pressure has
changed from factory setting
of 80 PSI
Tee into the Control Air Pressure outlet to check
pressure. SEE “FACTORY SETTINGS”
Adjust to set at 80 PSI.
System contamination,
Main filter collapsed due to
improper maintenance causing
control and logic valve
malfunctions.
Check main filter as outlined. If filter has
collapsed, use schematic and tube diagrams
to trace back through tubing, valve bodies (VB-2,
VB-3, VB-4) logic elements (L-4 L-5) to find where
system is plugged or which device is malfunctioning.
Clean out or replace tubing or device.
Correct cause of contamination.
TRIGGER DOES
NOT START BLAST
CYCLE
PHX-200 not ARMED
(indicator red)
Turn ARM selector clockwise,
(indicator should turn green)
Trigger Lines improperly
connected
Check trigger lines at the machine and at the gun.
Trigger Return Filter F3 plugged Check filter and replace element if necessary.
Trigger Line contamination
Blow out trigger lines, correct cause of contamination
Trigger Valve failure
Check trigger valve for contamination, clean or
replace as necessary. Correct cause of
contamination.
Malfunctioning logic element.
Check operation of L3, replace if necessary.
System contamination,
Main filter collapsed due to
improper maintenance causing
control malfunction.
Check main filter as outlined. If filter has
collapsed use schematic and tube diagrams to
trace back through tubing, logic element (L-3)
to find where system is plugged or which device
is malfunctioning. Clean out or replace tubing or
device. Correct cause of contamination.
TRIGGER STARTS
BLAST AIR BUT NO
ICE COMES OUT OF
GUN
There are no dry ice pellets in
the hopper
Load fresh ice into hopper
Ice Rate set to low
Turn Ice Rate Regulator clockwise to increase.
Ice bridging in hopper
With Pellet Screen in place use poker to break up the
bridge. This symptom is usually caused by poor ice
quality and high humidity areas.
Water ice accumulation in
hopper.
Water ice forms in high humidity areas and when
ice is left idle in hopper for long periods of time.
Clean and dry hopper thoroughly before refilling.
