6.2.10 Clean cycle
Menu for setting the opening and closing times for the “FCV” Filter Cleaning Valve.
FCV cleaning cycle repeats X times depending on the value of parameter ‘On’.
This function is always active when filter cleaning takes place.
ESC OK
Clean Cyc 1/1
Tch = 05:00s
Tpu = 01:00s
On
= 3
Cnt = 0
Tch = Vacuum Building time (Charge Time): Default is 5 seconds.
Tpu = Clean pulse time. Default is 1 second.
On = Number of cleaning pulses. Default is 3 pulses.
Cnt = 0: Elapsed cleaning pulses.
NOTE!
For the parameter ‘On’, the minimum value = 1.
NOTE!
If On is set to 0, No filter cleaning is performed.
Time duration for a cleaning cycle below:
Example: 1 Cleaning pulse
On=1, Tch=5, Tpu=1
→
On * (Tch + Tpu) = 1*(5+1) =6s where Tch=05:00s and Tpu=01:00s.
The default time for a complete cleaning cycle is 6 seconds.
Example: 2 Cleaning pulses
On=2, Tch=5, Tpu=1
→
On * (Tch + Tpu) = 2*(5+1) =12s where Tch=05:00s and Tpu=01:00s.
The default time for a complete cleaning cycle is 12 seconds
6.3 Standard cleaning process
The filter cleaning process is always activated after the pilot signal (PS) or (PSIFC) has disappeared and DIR Time
has elapsed.
The filter cleaning valve opens and the filter cleaning process generates a preset number of cleaning pulses.
The unit then goes into Idle mode keeping the cleaning valve open.
See function in Section 6.2.10 Clean cycle to set numbers of pulses and related parameters.
See function in Section 6.2.9 FCTmr to activate Timer controlled Filter cleaning.
The Filter cleaning process can be interrupted by Pilot Signal Interlocking functions, PSIFC = Pilot Signal Inter-
locking Filter Cleaning.
See Section 6.4 Standard Pilot Signal (PS) input .
