(terminals7, 8). 

- 

Input „Start / Stop“ bridge 

terminals 7, 8. 

No downtime cleaning 

- 

Parameter 04 = 0 

(downtime cycles) 

- 

Set parameter 04 

"Downtime cycles" to another 

value 

 

-

present 

- 

Apply signal to input „Start / 

Stop“ terminals 7, 8. 

Cleaning not effective 

- 

Interval too long 

- 

Set parameter 03 "Interval 1" 

to a lower value 

 

- 

Pressure too low 

- 

Pressure to 6 ... Set pressure 

to 8 bar (min. 5 bar) 

 

 

- 

Set parameter 03 "Interval 1" 

to a higher value 

 

-
