Malfunction
Possible cause Remedy
VPPM-..C1 not re-
acting
Supply vo ltage not applied, POWER LED
does not light up
• Check the 24V DC supply
voltage
Set value vo ltage or set value current not
applied
• Check controller
• Check connection
VPPM-... C1 defective • Send the dev ice 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 th e pressure
at th e o utput can increase or diminish).
– Supply pressure P1 too low
• Replace supply cable
• Increase supply pressure
UP/DOWN but-
tons on th e
VPPM-...C1 do not
react.
Voltage is present at digital inputs D1 and
D2
• Apply 0V DC to digital in-
puts D1 and D2.
