10 Causes of faults and remedies
10.1 Optical displays
LED allocation see chapter “Bus status display” on page 107.
Link / Data
Activity -
LED
Cause
Remedy
OFF
Voltage supply absent or too low
- Check voltage supply, wiring
- Is the voltage supply in the permissible range?
No Ethernet connection
Check Ethernet cable
Hardware error,
measuring system defective
Replace measuring system
FLASHING
(green)
Measuring system ready for
operation, Ethernet connection
established, data transfer active.
–
ON (green)
Measuring system ready for
operation, Ethernet connection
established, no data transfer.
FLASHING
(yellow)
Measuring system ready for
operation, Ethernet connection
established, data transfer active.
Detected a transmission error on
PORT. Media Counters (attribute 5 of
object 0xF6, Ethernet Link) displays
an error, see on page 163.
Frame errors occurred but that don‘t effects a
measuring system error. The LED state
switches back to “green“ after 60 sec.
ON (yellow)
Measuring system ready for
operation, Ethernet connection
established, no data transfer.
Detected a transmission error on
PORT. Media Counters (attribute 5 of
object 0xF6, Ethernet Link) displays
an error, see on page 163.

Cause
Remedy
OFF
Voltage supply absent or too low
- Check voltage supply, wiring
- Is the voltage supply in the permissible range?
Hardware error,
measuring system defective
Replace measuring system
ON (green)
Measuring system ready for operation
(no error)
–
FLASHING
(green)
Measuring system has got
parameters which were not activated
yet
Activate or save the parameters via one of the
Service Codes 0x0D, 0x16 or attribute 112 from
Class Code 0x23.
See Common Services on page 123 and
Attribute 112, Accept Parameter on page 149.
ON (red)
Device hardware error (such as:
measuring- or EEPROM error)
Try to restart the device: Voltage OFF/ON. If the
error arises repetitive, the measuring system must
be replaced.
FLASHING
(red)
A command could not be executed
Check the plausibility of the command
