12 Troubleshooting
Table 13 contains an overview of malfunctions, possible causes, and remedies.
13 Technical Data
If you cannot remedy a malfunction, please contact AVENTICS GmbH. The
address is printed on the back cover of these instructions.
Table 13:
Table of malfunctions
Malfunction
Possible cause
Remedy
No output pressure
present
No power supply
Connect the power sup-
ply.
Check the polarity of the
power supply.
Switch on system com-
ponent.
No set point stipulated
Stipulate a set point.
No operating pressure
Connect the operating
pressure.
Output pressure too low
(less than the set point)
Operating pressure too low
Increase the operating
pressure.
A consumer with a high air
consumption is located in
the EV1X operating line and
results in a large pressure
drop in the device.
Reduce air consumption.
Operating pressure less
than 1 bar above the
maximum output pressure
to be controlled.
Adjust the operating
pressure to at least 1 bar
above the maximum
output pressure to be
controlled.
Air is audibly escaping
Seal is missing or damaged
Check the seals and re-
place, if necessary.
Pressure regulator is not
leaktight
Exchange the pressure
regulator
Pressure regulator
emits short pressure
pulses
Device with current input is
operated with voltage set
point
Stipulate the correct type
of set point
Outlet pressure jumps
to the level of the oper-
ating pressure
Set point too high
(> 20 mA or > 10 V)
Stipulate the correct set
point
Output pressure too
high
Dynamic pressure in ex-
haust
Check the exhaust line
DIAG LED illuminated
red
Parameter error
Stipulate valid parame-
terization
Safety cut-off active
Exchange device since a
pressure sensor is defec-
tive.
