5 Product overview
5.1 Functional principle
A built-in pressure sensor records the pressure at the working port and compares
this value with the setpoint value. In the event of deviations between the setpoint
value and actual value, the valve regulates until the outlet pressure has reached
the setpoint value.

6 Transport and storage
– Store the product in a dry, UV- and corrosion-protected environment.
– Ensure short storage times.
7 Mechanical installation
1. Make sure there is sufficient space for the connecting cable and tubing con-
nections.
ÄIn this way you will prevent the connecting lines and the tubes from kink-
ing.
2. Place the valve as close to the consumer as possible.
ÄThis leads to improved control precision and shorter response times.
Mounting options of the valve:
– Through-hold mounting of the in-line valve through 3lateral through-holes
– Mounting of the in-line valve to H-rails using H-rail mounting VAME-P7-T

8 Installation
8.1 Pneumatic installation (in-line valve)
Valves for standard operation (overpressure)
1. Attach tubing to the following connections:
– Compressed air connection (1) è Fig.3
– Air connection (2) è Fig.2
2. Mount a silencer to the exhaust port (3) or remove the exhaust air with ducts
è Fig.3.
Valves for vacuum operation (reversible operation)
1. Attach tubing to the following connections:
– Vacuum connection (3) è Fig.3
– Air connection (2) è Fig.2
2. Mount silencer to the compressed air connection (1), to protect the valve from
coarse dirt particles è Fig.2.
Operating medium
NOTICE!
Pay attention to compressed air quality.
Damage to property or loss of function from lubricated compressed air.
• Operate product only with unlubricated compressed air.
• Observe the requirements for compressed air quality èTechnical data.
8.2 Electrical installation
WARNING!
Risk of injury due to electric shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
• Observe IEC60204-1/EN60204-1.
1. If a screened cable is used: earth the shield at the cable end farther away
from the valve.
2. Install electrical connecting cable without squeezing, kinking or stretching.
3. Screw electrical connecting cable onto the M8 plug connector. Tightening
torque maximum 0.3Nm

LED
indicator
Status and meaning
LED illuminates green:
– Operating voltage is present and within the permissible range.
– No error is present.
– Setpoint signal lies in the permissible range (0…10.8V or 2.5…20.5mA).
LED flashes red:
–Operating voltage lies above the permissible range (>29V).
LED flashes alternately red and green:
–Setpoint signal lies above the permissible range (>10.8V or >20.5mA).
–Setpoint signal lies below the permissible range (<2.5mA).
LED is off:
– No operating voltage applied.
–Operating voltage lies below the permissible range (<19V).

11.2 Fault clearance
Fault description Cause Remedy
Operating voltage not applied Check operating voltage con-
nection.
No setpoint voltage Check controller and connec-
tion.
Valve does not react.
Compressed air supply not
present/insufficient
Check compressed air supply.
Flow rate is too low. Restriction of the flow cross
section due to connection tech-
nology (swivel fittings).
Use alternative connection
technology.
Pressure remains constant des-
pite modified setpoint specific-
ation.
Supply cable breakage; the last
outlet pressure set is main-
tained but not regulated. Slow
pressure drop due to leakage.
Replace supply cable.
Setpoint value is not reached. Inlet pressure p1 is too low. Increase inlet pressure p1.
Maintain permissible maximum
operating pressure

12 Dismounting
1. Switch off setpoint voltage.
2. Switch off operating voltage.
3. Switch off compressed air supply.
4. Remove electrical connecting cables.
5. Remove compressed air lines.
6. Dismantle the product.
