Proline Promag 55 FOUNDATION Fieldbus

Hauser
Faulty connection to the fieldbus host system
No connection can be made between the fieldbus host system and the measuring device.
Check the following points:
Supply voltage
Transmitter
Check the supply voltage
→
Terminals 1/2.
Device fuse
Check device fuse
20 to 260 V AC and 20 to 64 V DC: 2 A slow-blow / 250 V
Fieldbus connection
FOUNDATION Fieldbus: check the data cable
Terminal 26 = FF +
Terminal 27 = FF
−
Fieldbus connector
(Option)
• Check pin assignment/wiring
• Check connection between connector/fieldbus port.
Is the coupling ring tightened correctly?
Fieldbus voltage
Check that a min. bus voltage of 9 V DC is present at terminals 26/27.
Permissible range: 9 to 32 V DC
Network structure
Check permissible fieldbus length and number of spurs
Basic current
Is there a basic current of min. 12 mA?
Bus address
Check bus address: make sure there are no double assignments.
Bus termination
Is the FOUNDATION Fieldbus H1 correctly terminated?
Each bus segment must always be terminated with a bus terminator at both ends (start and
finish). Otherwise there may be interference during data transmission.
Current consumption,
permitted 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.
Device Description (DD)
Instal the DD if you cannot access the manufacturer-specific parameters.
