AVENTICS™ AV-EP | R414007537-BAL-001-AB | English
On devices with display, the LEDs (48) are in-
tegrated in the display housing; the LEDs on
the rear are inactive.
The LEDs on the AV-EP pressure regulator
show the messages listed in Table 5
ing of the LEDs on the AV-EP pressure regula-
tors for fieldbus
connection.
u Before commissioning and during opera-
tion, regularly check AV-EP functions by
reading the LEDs.
Meaning
No electronics power supply present
Electronics power supply present
Valve power supply below the bottom tolerance limit
of 19.2 V DC (24 V DC -20 %)
Valve power supply above the bottom tolerance limit
of 19.2 V DC (24 V DC -20 %)
Set point = 0 bar
The actual value is outside of the tolerance.
The actual value is within the tolerance.
Safety cut-off active or parameter error (see chap-
ter 15 g 15. Troubleshooting)
The LEDs serve to monitor voltage and diag-
nosis.
On devices without display, the LEDs (47) are
on the rear.
On devices with display, the LEDs (48) are in-
tegrated in the display housing; the LEDs on
the rear are inactive.
