15 Troubleshooting

Table 14 contains an overview of malfunctions, possible causes, and remedies.
If you cannot remedy a malfunction, please contact AVENTICS GmbH.
The address is printed on the back cover of these instructions.

No set point stipulated
No supply pressure present Connect the supply
Output pressure too low Supply pressure too low
(less than the set point)
A consumer with a high
air consumption is located
in the AV-EP operating
line and results in a large
pressure drop in the device.
