7 Troubleshooting and diagnosis options
7.1 Optical displays, LEDs
red LED
green LED
Cause
Remedy
off
off
Absence of voltage supply
Check voltage supply, wiring
Bus cover not mounted and
screwed on correctly
Check bus cover for correct seating
Bus cover defective
Replace bus cover
Hardware error, measuring
system defective
Replace measuring system
on
10 Hz
Parameterization- or configuration
error:
 Value for the external Inputs
Preset1/Preset2 out of
measuring range (optional).
 Limit switch values out of
measuring range (optional)
 Installed device master file
does not match to the
measuring system
Measuring system does not start
at the bus.
 Check parameter setting and configuration,
see chapter 6 from page 89
 The limit values of the preset or limit switches must
be within the programmed measuring system
range in steps - 1
 Check whether the device master file associated
with the measuring system has been installed or
configured.
 Replace measuring system
off
10 Hz
Unrecoverable measuring system
defect.
At activated "Commissioning
diagnostics" function an
additional diagnostic alarm is
triggered via the PROFIBUS:
 internal memory error
 position error (gear reduction)
Measuring system is running at the
bus.
Switch supply voltage OFF/ON. If the error persists
after this measure, the measuring system must be
replaced.
1 Hz
on
Measuring system has no
allocation to a master, no data
exchange
 Check adjusted station address
 Check projection and operating status of the
PROFIBUS master
 Is there a connection to the master?
 Check whether the device master file associated
with the measuring system has been installed or
configured.
off
1 Hz
Parameterization- or configuration
error in a PNO compatible
nominal configuration:
Parameter "number of
revolutions" is not a power of two
-> the data have been corrected
automatically, the measuring
system is running at the bus.
 Check projection and operating status of the
PROFIBUS master
 Check the parameter data of the PNO compatible
nominal configuration, see chapter 6 from page 89
off
on
Measuring system operational,
no error, bus in cycle
