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

Maintenance and care
• Switch off the following sources of energy before cleaning the exterior of the
device:
– Operating voltage
– 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.

Disassembly
Note
Residual pressure must be eliminated.
1. Switch off the following sources of energy before dismantling:
– Operating voltage
– Compressed air
2. Separate the respective connections from the MS9-SV-...-C.

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).
