8.4 Default ClenCyl(T) Parameter Set-
tings
Do not change these parameters if filter cleaning is
sufficient.
• TH=2s: Default FC pulse time.
• TL= 3s: Default Vacuum Load time.
8.4.1 Procedure to set ClenCyl(T) Parameter
In the function ClenCyl(T), the cleaning pulse time and
vacuum load time can be set.
8.4.2 Settings TH = Cleaning Pulse Time (FC
Valve opening Time)
The length of the pulse time is difficult to predeter-
mine. From experience, 1-3 seconds works in most ap-
plications. It is possible to use other timings, but it has
to be tested at the site. It is appropriate to start with
the default time.
8.5 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) se-
quence 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 at high
speed until the vacuum reading has passed the
setpoint (-35Pa). After a while, the motor speed is
slowing down and the vacuum reading returns to
the setpoint value.
The second and third FC pulses should be ex-
ecuted when the vacuum reading is approximately
5kPa higher than the setpoint, in this case when
the vacuum reading is approximate -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 at high
speed until the vacuum reading has passed the
setpoint (-35Pa). After a while, the motor speed
slows down and the vacuum reading returns to
the setpoint value. The second and third FC pulse
is executed when vacuum reading is more than
5kPa higher than the setpoint, 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 at high
speed until the vacuum reading has passed the
setpoint (-35Pa). After a while, the motor speed
slows down and the vacuum reading returns
to the setpoint value and the vacuum reading
is steady before the 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 Manu-
al Filter Cleaning (MFC)=SB2 Button or functions in
the software as Filter Cleaning (FltClean), Delta pres-
sure main filter (DPFClean), or Manual Filter Cleaning
(MFC)=SB2 Button. See figure 3.
9 FlexPAK IOT System
The new FlexPAK IOT device is prepared for the Ne-
derman Insight cloud-based IoT platform and commu-
nicates with the cloud via a router. This is a fast optim-
al and cost-effective solution for processing data and
providing improved intelligence. It is possible to sense
all vital parts of a FlexPAK system and its processes.
Sensors monitor key system functionalities, and col-
lected data are sent to the cloud for analysis and visu-
alization via dashboards. Warnings, Alarms and other
status messages are returned to the factory for local
measures to be taken.
Communication is one-way in the FlexPAK systems. It
means that you can only retrieve information from the
Logo PLC and VACON VFD.
All FlexPAK sold after the 6th of May 2019 are pre-
pared for IOT, which means that if you order a Flex-
PAK after this date, you can upgrade it with a commu-
nication kit for the Nederman Insight Cloud-based IoT
platform.
If you want to upgrade a FlexPAK system you can buy
sensor kits separately for the FlexPAK IOT system.
The sensors are monitored by the FlexPAK Control
system and have full functionality without the Cloud-
based IoT platform.
