9 Disassembly
On disassembly:
Switch off the following energy sources:
– operating voltage
– compressed air
Separate the respective connections from the VPPM-...C1.
Remove the VPPM-...C1 from the mounting surface/H-rail.

Malfunction Possible cause Remedy
VPPM-...C1 does
not react
Supply voltage not applied; POWER LED
does not light up
Check connection of the 24 V
DC supply voltage
Setpoint voltage or setpoint current not
applied
Check controller
Check connection
VPPM-... C1 defective Send the device to the Festo
repair service
Flow rate too low Restriction of the flow cross section due to
connection technology (swivel fittings)
Use an alternative connec
tion
Pressure rise too
slow
Large cylinder volume and long tube
length
Select different parameter
record
Use VPPM-...C1 with larger
nominal width

ation
– Supply cable breakage (the last set out
let pressure is maintained but not regu
lated. In the medium term the pressure
at the output can increase or diminish).
– Too little supply pressure P1
Replace supply cable
Increase supply pressure
