Troubleshooting instructions
Always start troubleshooting with the checklists below if faults occur after start up or during
operation. This takes you directly (via various queries) to the cause of the problem and the
appropriate remedial measures.
!
Note!
In the event of a serious fault, an indicator might have to be returned to the manufacturer for repair.
Follow the instructions in
Chap. 9.4 before returning the indicator to Hauser.
Check local display
No display visible - No connection
to the fieldbus host system
1.
For fault elimination, see below: ’Faulty connection to the fieldbus host system’
2.
Other possible causes of errors:
– Electronics module defective
È
Test with spare electronics module
È
Order
spare part
– Housing (internal electronics) defective
È
Test with spare housing
È
Order
spare part
3.
Field indicator defective

Replace indicator
No display visible - However,
connection established to the
fieldbus host system
1.
Check whether the display module is correctly connected to the electronics
module,
2.
Display defective
È
Test with spare display
È
Order spare part.
3.
Electronics module defective

Faulty connection to the fieldbus host system
No connection can be made between the fieldbus host system and the indicator.
Check the following points:
Fieldbus connection
Check the data cable
Fieldbus connector (optional)
Check pin assignment / wiring,
Fieldbus voltage
Check that a min. bus voltage of 9 V DC is present at the +/- terminals. Permitted
range: 9 to 32 V DC
Network structure
Check permissible fieldbus cable length and number of spurs,
Basic current
Is there a basic current of min. 11 mA?
Terminating resistors
Has the FOUNDATION Fieldbus H1 been terminated correctly?
Each bus segment must always be terminated with a bus terminator at both ends
(start and finish). Otherwise there may be interference in data transmission.
Current consumption
Permissible feed current
Check the current consumption of the bus segment:
The current consumption of the bus segment in question (= total of basic currents of
all bus users) must not exceed the max. permissible feed current of the bus power
supply unit.
Error messages in the FF configuration system
Problems when configuring function blocks
Transducer Blocks:
The operating mode cannot be set
to AUTO.
Check whether the operating mode of the Resource Block is set to
AUTO
→
MODE_BLK parameter group / TARGET parameter.
