4.1 Function
4.1.1 Functional principle
The VPPE-... is intended for regulating pressure proportionally to a specified set-
point value. Manually adjustable pressure regulators can be replaced by remotely
adjustable electric closed-loop controllers. Thisallows various machine paramet-
ers to be available quickly and automatically.

5 Mounting
1. Place the VPPE-... as close to the consumer as possible. This improves control
precision and reduces response times.
2. Push two screws (M4) into the holes for lateral mounting è Fig.2, 1 or the
holes for front mounting è Fig.2, aB, max. tightening torque: 2Nm.
3. Mount the VPPE-... in the intended position.
NOTICE!
• When installing the VPPE-…-E1T on the mounting rail IPM-PN-08-40x80-AL,
note that the compressed air supply corresponds to the total air consump-
tion. For more information see the assembly instructions for the VAME-PS-
MK.
6 Installation
6.1 Pneumatic installation
1. Remove the covers from the supply ports.
2. Attach the tubing to the following ports (è Fig.2):
Input supply port (1), position 2
Output supply port (2), position aJ
3. Mount a silencer at the exhaust supply port (3) (position aA) or extract the
exhaust air using ducts.
Operating medium
NOTICE!
Too much residual oil content in the compressed air will reduce the service life of
the valve.
• When using organic oils (oils that are based on synthetic esters or native
esters, e.g.rapeseed oil methyl ester), the maximum residual oil content of
0.1mg/m³ must not be exceeded (è Compressed air to ISO 8573-1:2010
[–:–:2]).
The position of the pneumatic ports depends on the variant ordered.
6.2 Electrical installation
WARNING!
Risk of injury due to electric shock.
• For the electrical power supply, use only PELV circuits in accordance with IEC
60204-1/EN 60204-1 (Protective Extra-Low Voltage, PELV).
• Observe the general requirements of IEC 60204-1/EN60204-1 for PELV cir-
cuits.
• Only use voltage sources that ensure a reliable electric separation from the
mains network in accordance with IEC 60204-1/EN 60204-1.
• Use the following connection accessories (è 3 Further information):
– plug socket with cable or
– plug socket cable, pre-assembled.
This ensures that the specified degree of protection IP65 and EMC is achieved.
NOTICE!
To guarantee EMC safety, the device must be earthed as follows:
• Use the earth terminal (è Fig.2, è Fig.3).
• Use the following earthing accessories (included in the scope of delivery):
– Self-tapping screw
– Flat plug
– Contact washer.
• Wire the VPPE-... in accordance with the plug pattern. Preferably use Festo
cables.

7 Commissioning
NOTICE!
• The VPPE-... interprets setpoint signals less than 0.1 V as 0 V and setpoint sig-
nals less than 4.16 mA as 4 mA. In this case, the output pressure is set to 0
MPa by activation of the exhaust valve. As a result, a defined valve condition
is assured at w = 0.
• Safety position: if the voltage variant setpoint value cable breaks, the output
pressure is set to 0 MPa. If the current variant cable breaks or if the supply
voltage fails, the output pressure is maintained uncontrolled. Leakage results
in a change of pressure over the long term.
1. Connect the VPPE-... with a setpoint value signal. The VPPE has a so-called
“differential input”. The setpoint signal is applied to the contact pin 2 and pin
4, where the lower potential must be connected to the contact pin 2 and the
higher potential to the contact pin 4.
Contact pin 2 (– setpoint value) can be connected to contact pin 3 (GND).
2. Energise the VPPE-... with direct current (supply voltage UV = 24 V DC ± 10%).
3. Pressurise the VPPE-... to at least 0.1MPa higher input pressure (p1) than the
maximum desired output pressure. This sets proportional output pressure
(p2).
The following output pressure range is then allocated to the setpoint value signal
range 0…10V or 4…20mA:

7.3 Configuring the output
– The display of the actual value at the analogue output [An] is 0…10V or
4…20mA depending on the ordered variant.
– If a switching output is selected, the following modes can be selected:
threshold value, window comparator or SP.O.
Switching points (SP...) and hysteresis (HY)
The switching point is only active when a threshold value or window comparator
is selected.
The value of the hysteresis specifies the tolerance for the deviation before a sig-
nal change occurs at the output (Pin 5).
Setting SP.O.
The SP.O. signal indicates that the setpoint value has been reached in the range
(+/-) of the set hysteresis.
If the threshold value comparator is set
Switching characteristic NO (normally open)
Switching characteristic NC (normally closed)

NOTICE!
When switching off the VPPE-..., make sure that the setpoint voltage or setpoint
current intensity is switched off first, then switch off the supply pressure and
finally the supply voltage.
The green status LED lights if the actual value is equal to the setpoint value of
within a range of ± 1% (FS) of the setpoint value.
Lock [Loc] - unlock [unL]
If a PIN code was entered with [Pin], [Loc] is shown in the display and the edit
mode is locked via the PIN code. If a flashing [0] appears, enter the correct pin.
After the correct PIN is entered, [unL] is displayed. If the input is incorrect, the
VPPE returns to the initial position.
9 Maintenance
– Clean the housing of the VPPE-... with a soft cloth only. The permitted clean-
ing medium is a mild detergent solution at max. 50°C.
