Total Filter Cleaning sequence time
Total Filter Cleaning sequence time(s) =
FCDely(TL = 2s) + (ClenCyl((TL = 3s)*3) + (ClenCyl(TH = 2s)*2) +IsoVDly (4s) =
2 + (3*3) + (2*2) + 4 = 19 seconds
8.5.1
Settings TL = Vacuum Load Time
Vacuum set points FlexPak 1000 = 20kPa, FlexPak 800 = 35kPa
Examples of adjustment
1.
Start the unit and activate the pilot signal (PS). Wait 6 seconds before pushing the
Filter cleaning button. After a while the filter cleaning (FC) sequence starts.
2.
Optimized (TL time) FlexPak 800 = -35kPa
After the first FC pulse and the FC valve has opened and closed again, the motor runs
on high speed until the vacuum reading has passed the set point (-35Pa). After a
while, the motor speed is slows down and the vacuum reading returns to the set point
value.
The second and third FC pulses should be executed when the vacuum reading is
approximately 5kPa higher than the set point, in this case when vacuum reading is
approximately -39kPa.
3.
To short (TL time) FlexPak 800 = -35kPa
If the vacuum not reached (-35kPa) and the motor speed is at maximum rpm.
Solution: Increase Parameter TL.
4.
To short (TL time) FlexPak 800 = -35kPa
After the first FC pulse and the FC valve has opened and closed again, the motor runs
on high speed until the vacuum reading has passed the set point (-35Pa). After a
while, the motor speed slows down and the vacuum reading returns to the set point
value. The second and third FC pulse is executed when vacuum reading is more than
5kPa higher than the set point, in this case when vacuum reading is above -40kPa.
Solution: Increase Parameter TL.
5.
To long (TL time) FlexPak 800 = -35kPa
After the first FC pulse and the FC valve has opened and closed again, the motor runs
on high speed until the vacuum reading has passed the set point (-35Pa). After a
while, the motor speed slows down and the vacuum reading returns to the set point
value and the vacuum reading is steady before next FC pulse is executed. For example
in this case, the vacuum reading is -35kPa for a while before the FC pulse is executed.
Solution: Decrease Parameter TL.
8.6
FC Start Impulse
This is the start impulse that comes from or Manual Filter Cleaning (MFC)=SB2 Button or
functions in the software as Filter Cleaning (FltClean), Delta pressure main filter (DPFClean),
or Manual Filter Cleaning (MFC)=SB2 Button. See figure 3.
