Procedures/remedy
Switch off the gun control units, wait
until the differential pressure returns
to normal again. Check the cleaning
cycles by ear, if necessary, shorten
the pause times in the cleaning cycle.
Check, if the cleaning pressure is set
on 5 bar on the pressure input valve
(see also the section
"Troubleshooting" in the After Filter
operating manual)
Warning:
If the pressure gauge shows a
pressure rise higher than 3 kPa,
contact your Gema agent
immediately!
Too little pressure, too much exhaust
air, because too little or no air
resistance
Filter housing door is open
Sieve machine not fitted tightly on the
cyclone separator
Waste container not fitted tightly (see
also the troubleshooting section in the
After Filter manual)
Pressure too high, insufficient
exhaust air because the air resistance
is too high
Filter clogged (valves defect or
cleaning pressure too low, at least 5
bar)
Poor compressed air quality (contains
oil or water)
Malfunctions on running-in, until the
filter cake is built up on the filter

"Troubleshooting" section in the After
Filter operating manual)
Turn on the gun control unit, or
correct the fault in the gun control unit
