Application and function
The VPPM-...C1 has been designed for regulating a pressure proportional to a
specified setpoint value. A built-in pressure sensor records the pressure at the
working line and compares this value with the setpoint value. If the actual value
differs from the setpoint value, the regulating valve is actuated further until the
output pressure reaches the setpoint value.

Requirements for product use
Warning
Depending on the functions of the machine/system, the manipulation of signal
states can cause serious injury to human beings and damage to property.
• Note that if the switching behaviour of the switching outputs is modified in
the EDIT mode, the new status will be effective immediately.
• Activate the password protection (security code) in order to prevent uninten-
tional modification by unauthorised third parties (
section 6 under EDIT
mode).
Note
Improper handling can result in malfunctions.
• Make sure that the following specifications are always observed in order to
ensure correct and safe use of the product.
• Compare the limit values in these operating instructions with those of your ap-
plication (e.g. operating medium, pressures, forces, torques, temperatures,
masses, speeds, voltages).
• Take into consideration the ambient conditions at the location of use.
• Comply with the regulations of the trade association, the German Technical
Control Board (TÜV), of the VDE or relevant national regulations.
• Remove all transport packing such as protective wax, foils (polyamide), caps
(polyethylene), cardboard boxes. The material used in the packaging has been
specifically chosen for its recyclability (exception: oil paper = residual waste).
• Use the product in its original status. Unauthorised modification is not permit-
ted.
