FlexPAK DX

6.5 Change control filter

WARNING! Risk of personal injury

• The vacuum and compressed air to the unit

must be turned off before commencing filter

change.

• Use proper protective equipment.

Always check the main filter for damage when

replacing the control filter.

The control filter should normally be replaced after

6000 hours of operation. The control filter must also

be replaced if damaged or if there is a high-pressure

drop over the control filter.
Follow the procedure below:
1 Access the filter by removing the lid and side of

the FlexPAK DX.

2 Disconnect the top piping of the filter housing and

open the top cover.

3 Remove and put the old filter in a large plastic bag,

or wrap it in plastic foil. Avoid dust spreading.

4 Fit a new filter cartridge in place. Ensure that the

filter cartridge is centred and that the rubber seal

on the housing is intact.

5 Close the top cover and reconnect the pipes.
6 Check the earth connection between the control

filter and GND1.

6.6 Check the filter cleaning function

WARNING! Risk of personal injury

Crush hazard. Pay attention when the com-

pressed air pressure cylinder and valve disc

move. Make sure that the protection hood over

the filter cleaning unit is fitted after the check.

Check the automatic filter cleaning as follows:
1 Check the automatic cleaning equipment once a

year.

2 Remove the top cover from the filter and inspect

the valve disc.

3 Start the unit and press the filter cleaning button,

see

Figure 8

. The compressed air cylinder should

lift the valve disc. Loud noise can be heard as air

rushes into the filter bin to blow off the dust from

the outside of the filter package. This will be re-

peated 3 times for each filter cleaning cycle.

4 Stop the vacuum unit and shut off the air supply.
5 Check the valve disc fastening, damage and wear.

Replace if required.

6 Replace the protecting top cover.

6.7 The motor and the fan unit

Inspect and clean the motor compartment regularly.

The motor has 2 ball bearings. The bearings are to be

replaced after approximately 15,000 hours of opera-

tion. If the ambient temperature often reaches 35°C

(95°F), the time between replacements is to be re-

duced. In any case, the bearings are to be replaced

every fifth year.
The bearings are a standard type. Contact Nederman

or an authorized Nederman distributor for replace-

ment of the bearings.
Old grease is to be removed and new grease used. The

grease is to meet the DIN 51825-K2N 40, SKF LGHP 2

or FAG Arcanol Multitop standards.

6.8 Cooling filter for the frequency con-

verter

The service life of the cooling filter for the frequency

converter depends on the air-bound dust surround-

ing the vacuum unit. The expected service life is 6–48

months. Check the filter regularly through the filter

holder grid. If the filter is clogged, the frequency con-

verter will shut off due to overheating.
Ensure that the cooling filter is not exposed to any

combustible materials. Running the unit without the

cooling filter may cause serious damage. When chan-

ging the filter, see the label placed over the filter in-

take.
The unit may never be run without a cooling filter for

the frequency converter.

6.9 Loading new software

This section is only for Nederman qualified ser-

vice technicians. Only Nederman qualified ser-

vice technicians may make changes to, or in-

stall new software.

Make notes of actual parameter settings.

6.9.1 Frequency converter control panel

To change the software or install new software for

the unit, the parameters in the frequency converter

have to be changed by means of the frequency con-

verter control panel available from Nederman.

6.9.2 Firmware and software labelling

The software version is found on a label taped

to the front of the PLC. LOGO 8 software is up-

dated using an SD Card. Follow the included in-

structions when the software needs to be up-

dated.

To find the firmware and software revision

number in the PLC display, see

Figure 8

, item 1.

Pressing ‘OK’ when the PLC displays this menu

will show this information. See also the PLC

Settings Manual.
