7 Troubleshooting
Intake pipe blocked, defective, buckled or not connected
Speed not set correctly
Motor / Control defective
Motor bearing defective
Motor fan polluted
Pos.1: Main switch
Pos.2: Real time operation hour counter
Pos.3: Filter display
Green LED: Filter ok,
1 st yellow LED: 30% filter saturation
2 nd
3 rd yellow LED: 100% filter saturation
When reaching 100%, the system will shut
down!
Filter differential pressure not reached yet
No or faulty compressed air supply
Cleaning module not connected
Cleaning module defective
Filter cartridges heavily polluted / filter lifetime used up
Filter lifetime used up / Filter saturated completely / not
cleanable any more
Dust collection box missing
Dust collection box leaky
System is switched off
No or faulty compressed air supply
No or faulty compressed air supply
Cleaning control not activated
Cleaning control configured wrong
Interval cleaning activated at cleaning control
Shut-down cleaning activated at cleaning control
Clean or exchange intake pipe
Increase speed by speed setter (front) or remote control
Contact national manufacturer representative
Exchange motor or contact national manufacturer representative
Check filter for leaks, possibly contact national manufacturer
representative
yellow LED: 75 % filter saturation
Filter differential pressure monitoring controls the cleaning process.
If only the first two LEDs display, everything is O.K.
Check pressure or connect compressed air supply
max. 2bar
Connect the cleaning module's cable to the socket under the
interface
Check cable and magnet valve for damages or contact national
manufacturer representative
Filter saturation ca. 75%, system tries to decrease differential
pressure → order filter cartridges!
The system will operate the cleaning process 5 times at 75%. If the
filter differential pressure does not decrease, the filters are
saturated completely → exchange filter cartridges!!!
Open service door and insert dust collection box
Open service door and check gaskets, dust collection box fastened
correctly?
Switch on system at main switch
Check pressure or connect compressed air supply
max. 4bar
