Safety setting

Wire break Voltage type
Setpoint Output pressure drops to 0 bar.
Supply volt- The last value is saved. The output pressure is maintained but not regulated. In
age the medium term the pressure at the output can increase or diminish.

Eliminating malfunctions

Cause
– Value fallen below limit value (setpoint value)
– Value exceeded limit value (setpoint value)
– Undervoltage in the 24 V operating voltage
– Overvoltage in the 24 V operating voltage
– Hardware error
– Temperature range exceeded in VPPM-...C1
Fig. 33
Malfunction Possible cause
VPPM-..C1 not re- Supply voltage not applied, POWER LED
acting does not light up
Set value voltage or set value current not
applied
VPPM-... C1 defective
Flow too low Restriction of the flow cross section due to
connection design (swivel fittings)
Pressure increase Large cylinder volume and long tubing
too slow
Pressure constant – Supply cable breakage (the last output
pressure set is maintained but not regu-
despite modified
lated. In the medium term the pressure
setpoint value
at the output can increase or diminish).
specification
– Supply pressure P1 too low
UP/DOWN but- Voltage is present at digital inputs D1 and
tons on the D2
VPPM-...C1 do not
react.

13 Technical data
Note
Certain variants of the product have been certified by Underwriters Laboratories
Inc. (UL) for the USA and Canada. Observe the following if the UL requirements
are to be complied with in your application:
• Rules for observing the UL certification can be found in the separate UL-spe-
cific documentation. The relevant technical specifications listed there also
apply here.
• The technical data in this documentation may show values deviating from this.

Remedy
• Check the 24 V DC supply
voltage
• Check controller
• Check connection
• Send the device to Festo for
repairs.
• Use an alternative connec-
tion
• Select different parameter
record
• Use larger size VPPM-...C1
• Replace supply cable
• Increase supply pressure
• Apply 0 V DC to digital in-
puts D1 and D2.

1) The valve is intended for use in an industrial environment. Outside of industrial environments, e.g. in
commercial and mixed-residential areas, actions to suppress interference may have to be taken.
