Troubleshooting
The air cannon is not
triggered.
Electrical connections of the
solenoid valves.
Make sure that the electrical
connections are flawless. Check
the voltage. Check whether the
control system is switched on and
whether signals are being sent.
No pressure in the air
cannon tank.
See “The air cannon does not fill”
fault.
Control line leaky or
incorrectly connected.
Check whether the control line is
corrected connected to the air
cannon and to the solenoid valve
and whether it is leak-tight.
The air cannon's vent ports
are closed.
Inspect the two 1" elbows. They
MUST NOT
be closed or reduced
in diameter. Turn the nuts
downwards if possible.
Valve piston installed
backwards.
Rotate the valve
body piston 180°.
See Section 6.3.2
The air outlet or nozzle is
clogged.
Remove the clogging.
The control line is too long. Check whether the compressed air
line is too long (over 30 m).
Operating pressure too low. Check whether the operating
pressure is 3 to 10 bars.
Control signal functions too
briefly.
Make sure that the magnetic valve
remains activated long enough for
correct operation (at least 1
second, no more than 2 seconds).
The air cannon
sputters after it is
triggered and the air
pressure drops only
slowly or never
reaches the zero
value.
The air outlet or nozzle is
clogged.
Remove the clogging.
The air cannon
triggers but has no
impact.
The manual safety guard is
closed.
Open the safety guard.
