Warning..................................................

Products under pressure can cause injury to human

beings and damage to property.

 Before carrying out installation and maintenance

work, switch off the compressed air supply.

 Use shut-off valves in the compressed air supply

tubing for exhausting the system.

Note......................................................

Fitting and commissioning to be carried out only by

qualified personnel in accordance with the operating

instructions.

This product is designed to be operated with com

pressed air only. The product is not suitable for use

with other media (fluids or gases).

With controllers without secondary venting (only

applies to MS9--OS):

Due to the design of these controllers it can result in

the output pressure p2 increasing to the maximum

operating pressure p1 when there is no consumption at

the output. When using a regulated device a small

permissible internal leak without air consumption also

leads to an increase in pressure at p2 and must be

considered in the design phase.

Pressure regulator MS9-LR,

1 Application

The filter regulator valve MS9-LFR and the pressure

regulator MS9-LR are designed to regulate compressed

air in the subsequent line to the set output pressure p2.

The MS9-LFR/LR smoothes out fluctuations in pressure

here. The output pressure p2 can be set within the

pressure regulating range (è Technical data chapter)

independently of the input pressure p1.

The filter regulator valve MS9-LFR and the filter MS9-LF

with centrifugal separator remove dirt particles and

condensate from the compressed air blown through it,

while the water separator MS9-LWS removes condensate.

2 Requirements for product use

Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Improper handling can result in malfunctions. Make

sure that the following specifications are always

observed:

 Compare the maximum values specified in these

operating instructions with your actual application (e.g.

operating media, pressures, temperatures, flow rates).

 Comply with the regulations of the trade association,

the German Technical Control Board or relevant national

regulations.

 Take into consideration the ambient conditions at the

location of use.

caps (polyethylene), cardboard boxes

(except for the sealing elements of the pneumatic con

nections).

 Use the product in its original condition without any

unauthorised modifications.

 Remove dirt particles in the supply lines by blowing out

 Please ensure that there is a supply of correctly

prepared compressed air.

3 Installation

3.1 Mechanical

Note. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Information about mounting module connectors,

sub-bases and mounting brackets can be found in the

operating instructions enclosed with the relevant

accessories.

 Note the direction of flow from 1 to 2.

The numbers 2 on the product housing serve as an

orientation (èFig. 2).

 Place the MS9-LFR/LF/LWS with sufficient space below

the filter bowl (min. 150 mm).

 Adjust the MS9-LFR/LF/LWS standing vertically (± 5°).

Direct mounting of an individual MS9--¾/1 with fasten

ing screws

1.Press all protective caps 3 forwards out of the sub-

base (è Fig. 3). To do this, push a narrow object

through the rear opening of the sub-base.

2.Fasten the individual device with four fastening screws

4 of size M6 and a minimum length of 90 mm

(è Fig. 4). The distance between the holes is 90 mm in

width and 66 mm in height.

Assembly with one or several already available service

units of the same series (è Fig. 5)

1.Dismantle the existing service unit string depending on

the planned location of the device within the string.

If the device is to be installed at the beginning or end of

the service unit string:

– Disconnect the compressed air line from the service

unit string or

– remove the sub-base from the service unit string.

If the device is to be fitted between two service units in

the service unit string:

– Remove the module connector MS9-MV 5 between

the two service units by loosening the screws.

2.Mount the device in the desired location.

3.Place the module connectors MS9-MV 5 in the grooves

of the MS9-LFR/LR/LF/LWS and the adjoining service

unit. There must be a seal between the service units.

4.Fasten the module connectors MS9-MV with two

screws.

5.Fit the removed parts and devices from step 1 together

into a service unit string again.

3.2 Pneumatic

If using screw connectors:

 Note the screw-in depth of the connecting thread.

MS9-...-AGG/AGH: 31.5 MS9-...-AQU/AQV: 31.5

 Screw the connectors into the pneumatic connections

using a suitable sealing material.

For MS9-LR--PO (è Fig. 6):

 Screw the connector into the pneumatic connection

12 in the cover 7 using suitable sealing material.

During installation make sure no dirt particles enter the

device.

4 Commissioning

Setting the output pressure on the MS9-LFR/LR

1.Pull the rotary knob upwards away from the housing

(ifnecessary, remove padlock and push in the unlocking

device 1 è Fig. 2).

2.Turn the rotary knob completely closed in the direction

of –.

3.Pressurise your system slowly.

4.Turn the rotary knob in the + direction until the

desired pressure is displayed on the pressure gauge.

The permissible output pressure (pressure regulation

range èTechnical Data chapter ) must not be

exceeded. Correctly pressurised, the operating

pressure p1 is at least 0.5 bar higher than the output

pressure p2.

5.Press the rotary knob down to the housing. The button

will then lock itself against unintentional turning.

If necessary:

 Press the unlocking device 1 (è Fig. 2) outwards. An

existing padlock LRVS-D protects the unlocking device.

Setting the output pressure p2 with control pressure p12

(MS9-LR--PO only)

1.Pressurise your system slowly.

2.Use an external pressure regulator to pressurize the

connection in the cover of the MS9-LR--PO with the

required control pressure p12. Note that the control

pressure must always be higher than the desired output

pressure. The diagram (è Technical data) shows the

difference between control pressure p12 and output

pressure p2.

Replacing the filter cartridge for MS9-LFR/LF

 Replace the filter cartridge if the flow is reduced in spite

of unmodified pressure setting.

1.Exhaust the device.

2.Push the unlocking slide 8 in the direction of the arrow

(è Fig. 7).

3.Turn the filter bowl by hand or by the hexagon as far as

possible in an anti-clockwise direction (as seen from

below] until it is heard to strike the stop.

4.Pull the filter bowl away from the device (è Fig. 8).

5.Turn the filter plate 9 in an anti-clockwise direction

(è Fig. 9).

6.Replace the filter cartridge if the pores are dirty

(è Fig. 10).

Hold the new filter cartridge only at the lower end. The

filter cartridge has a cone shape and must be pushed

into the carrier with the wider end first.

7.Place the new filter cartridge onto the filter plate and

tighten it hand-tight. (è Fig. 11).

8.Fit the individual parts together again in the reverse

sequence. The following checks must then be made:

– the locking pin of the filter bowl must face the large

recess in the housing (è Fig. 12).

– the unlocking slide must be heard to clip into place

when the end stop is reached(è Fig. 13).

9. Commission the system again.

10.Dispose of the used filter cartridge in compliance with

the local waste disposal stipulations.

Cleaning the filter cup aJ for MS9-LWS

The filter cup must be cleaned in regular intervals if there

are impurities in the condensate. The cleaning interval

depends on the level of contamination of the compressed

air used and the tubing system. Cleaning is required when

the sight glass is full of condensate and it doesnt drain

away. The filter cup, however, must be cleaned at least

once a year.

1.Drain the filter bowl if necessary by emptying it manu

ally.

2. Exhaust the device.

3.Loosen the 4 mounting screws aA on the bowl cover

(è Fig. 14).

4.Remove the bowl cover with the filter cup aJ from the

MS9-LWS. Make sure the O-ring aB is not lost.

5.Hold the exterior of the filter cup under running water.

Turn the filter cup when doing this. Use a soft brush to

remove any hard deposits from the filter cup. Do not

use any sharp objects as these can damage the filter.

6.Assemble the bowl cover and O-ring aB to the MS9-LWS

by using the 4 mounting screws aA.

7.Commission the system again.

Cleaning the service unit

If the device is dirty, clean the exterior with a soft cloth.

Permitted cleaning agents are soap suds (max.+60 °C) or

petroleum ether (free of aromatic compounds).
