2 Application and function
The VPPM-...C1 has been designed for regulating a pressure propor tional to a
specified setpoint value. A built-in pressure sensor rec ords the pressure at the
working line and compares this v alue 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.

4 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 pro perty.
• 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 a nd 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.
