of the machine or system in which this product will be used.
• Keep these operating instructions during the entire product life cycle.
• Observe the rules/information of the trade association, the VDE specifications
and relevant national regulations at the location of use.
3.1 Technical requirements
General conditions for the correct and safe use of the product, which must be
observed at all times:
• Maintain the specified limits (e.g. for pressures, temperatures and electric
voltages).
• Make sure there is a supply of correctly prepared compressed air in accordance
with the specifications on the medium.
• Before mounting, remove particles in the supply lines through appropriate
measures. In this way, you protect the product from premature failure and high-
er wear.
• Pressurize your entire system slowly. This allows avoidance of abrupt move-
ments.
• Observe the warnings and instructions in these operating instructions.
• Use the product in its original state, without any unauthorised product modifica-
tions.

4 Mounting and installation
4.1 Mechanical
Note
Information about mounting of module connectors, sub-bases and mounting
brackets can be found in the operating instructions enclosed with the relevant
accessories.
• Place the MS9-SV-...-C as close as
possible to the location of use.
• Place the MS9-SV-...-C in such a way
that you have sufficient space for a
silencer.
• The mounting orientation is any de-
sired.
• Observe the flow direction from 1 to
2. Serving as orientation are the nu-
merals 1on the product housing.
Fig. 5 Flow direction

Combination with service units of the MS series
1. Place the module connectors
MS9-MV 2in the grooves of the in-
dividual devices. A seal 1is re-
quired between the individual
devices.
2. Fasten the module connectors
MS9-MV with 2 screws.

Port 1 and 2
If using fittings:
• Observe the maximum permissible screw-in depth of the connecting threads:
ISO 228 NPT
MS9-…-¾/1: 18.5 mm MS9-…-N¾/N1: 18.5 mm
MS9-…-AGD/AGE/AGF: 18.5 mm MS9-…-AQR/AQS/AQT: 18.5 mm
MS9-…-AGG/AGH: 31.5 mm MS9-…-AQU/AQV: 31.5 mm
Fig. 7 Max. screw-in depth
• Make sure that the compressed air lines are connected correctly.
• Screw the connectors into the pneumatic ports using suitable sealing material.
Port 3 (thread size G1 or NPT1)
When exhausting a system through the MS9-SV-...-C, high sound pressure levels
are generated. We therefore recommend that you use a silencer.
Note
The silencer listed in the accessories U-1-B can be retrofitted on replaced only on
equipment with metric threads.
When retrofitting the silencer on a device with NPT thread at port 3, the cover of
the MS9-SV-...-C can be destroyed. When retrofitting, an adequate silencer with
NPT thread must be used.
• Screw the silencer into the pneumatic port 3.
• Make sure that there is unrestricted exhausting. Neither the silencer nor port 3
should be blocked.
5 Electrical connection
Warning
Electrical connections should be established only in the absence of voltage and
by qualified personnel.
Warning
Use only power sources which guarantee reliable electrical isolation of the oper-
ating voltage in accordance with IEC/EN 60204-1. Consider also the general
requirements for PELV circuits in accordance with IEC/EN 60204-1.
Note
Long signal lines reduce the resistance to interference.
• Make sure that the signal cables are not longer than 20 m.

6 Commissioning
To start up the device, proceed as follows:
1. Apply operating pressure p1.
2. Switch on the supply voltage.
The output pressure p2 is built up slowly. The filling time “t” is set through the
flow control screw attached to the cover. The output pressure rises correspond-
ing to the set throttle point (Fig. 12). If the preset pressure switching point
(PSP) is reached, the main seat of the valve opens (Fig. 13). The MS9-SV-...-C
is then ready for operation.
No further settings are required.
Tamper protection
To prevent a manipulation of the settings, setting and control elements can be
equipped with a cover 11 Accessories.
7Operation
Note
Exhaust with a voltage drop
8 Maintenance and care
• Switch off the following sources of energy before cleaning the exterior of the
device:
–Operatingvoltage
– Compressed air
• If needed, clean the MS9-SV-...-C from outside.
Soap suds (max. +50 °C), petroleum ether and all non-abrasive cleaning agents
may be used.
9 Disassembly
Note
Residual pressure must be eliminated.
1. Switch off the following sources of energy before dismantling:
–Operatingvoltage
– Compressed air
2. Separate the respective connections from the MS9-SV-...-C.
10 De-commissioning and disposal
In coordination with the waste management company, the product can be com-
pletely disposed of through metal recycling (e.g. EAK 17 04 02). If necessary, the
solenoid valve is dismantled and disposed of separately in electronic scrap recyc-
ling (EAK 16 02 16).

13.4 Pressure switching point
With the main throttle (MT) located in the cover, a slower pressure build-up of
output pressure p2 is achieved. If the output pressure p2 has reached the switch-
through pressure, the valve opens and the complete operating pressure p1 builds
up at the output. The pressure switching point can be set by turning the adjusting
screw for the pressure switching point (PSP).
