Programs and control unit
Explanations
Cleaning
process
*
Cleaning cycle for container 90 sec The circ. pump stops and the drain pump runs for 2 sec. The circ.
pump runs for 3 sec. and then rests for 5 sec. In total this is repeated
eight times, but the fifth time the circ. pump is resting for 8 sec instead
of 5 sec, when spray arm diverter is switching to the upper spray arm.
Inlet
process
**
Inlet process 255 sec A flow meter signals the flow in pulses. The control unit (CU)
determines how many pulses to be calculated for each inlet. If not 80
pulses has been reached within 60 sec or a specific number of pulses
is not reached within 255 sec, the program will be interrupted.
Drain
process
***
Drain process 120 sec The drain pump starts and pumps out until the level sensor reaches
a specified value. After that, the drain pump continues for additional
10 sec. The total time depends on how long it takes to reach the
specified value from the level sensor. If the specified value is not
reached within 120 sec, the program will be interrupted.
