Malfunction
Possible cause
Remedy
VPPM-..C1 not re-
acting
Supply voltage not applied, POWER LED
does not light up
• Check the 24 V DC supply
voltage
Set value voltage or set value current not
applied
• Check controller
• Check connection
VPPM-... C1 defective
• Send the device to Festo for
repairs.
Flow too low
Restriction of the flow cross section due to
connection design (swivel fittings)
• Use an alternative connec-
tion
Pressure increase
too slow
Large cylinder volume and long tubing
• Select different parameter
record
• Use larger size VPPM-...C1
Pressure constant
despite modified
setpoint value
specification
– Supply cable breakage (the last output
pressure set is maintained but not regu-
lated. In the medium term the pressure
at the output can increase or diminish).
– Supply pressure P1 too low
• Replace supply cable
• Increase supply pressure
UP/DOWN but-
tons on the
VPPM-...C1 do not
react.
Voltage is present at digital inputs D1 and
D2
• Apply 0 V DC to digital in-
puts D1 and D2.
