Absence of voltage supply
Bus cover not mounted and screwed
on correctly
Bus cover defective
Hardware error, measuring system
defective
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
Internal memory error
Position error (gear reduction)
Measuring system does not start at
the bus.
Blink mode is supported only in case
of older measuring
generations.
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.
Measuring system has no allocation
to a master, no data exchange
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.
Measuring system operational,
no error, bus in cycle
TR - ECE - BA - DGB - 0076 - 08
Remedy
Check voltage supply, wiring
Check bus cover for correct seating
Replace bus cover
Replace measuring system
−
Check parameter setting and configuration,
see chapter 6 from page 77
−
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.
−
Switch supply voltage OFF/ON
−
Replace measuring system
system
Switch supply voltage OFF/ON. If the error persists
after this measure, the measuring system must be
replaced.
−
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.
−
Check projection and operating status of the
PROFIBUS master
−
Check the parameter data of the PNO
compatible nominal configuration, see chapter
6 from page 77
