Trouble-shooting instructions
Always start trouble-shooting with the following checklist if faults occur after commissioning or
during operation. The routine takes you directly to the cause of the problem and the appropriate
remedial measures.
Check the display
No display visible and no
output signals present.
1.
Check the supply voltage
→
Terminals 1, 2
2.
Check device fuse
85 to 260 V AC: 0.8 A slow-blow / 250 V
20 to 55 V AC and 16 to 62 V DC: 2 A slow-blow / 250 V
3.
Measuring electronics defective
→
order spare parts
No display visible, but
output signals are present.
1.
Check whether the ribbon-cable connector of the display module is correctly plugged
into the amplifier board
2.
Display module defective
→
3.
Measuring electronics defective
→
order spare parts
Display texts are in a
foreign language.
Switch off power supply. Press and hold down both the
P
keys and switch on the
measuring device. The display text will appear in English (default) and is displayed at
maximum contrast.
Measured value indicated,
but no signal at the current
or pulse output

Error messages on display
Errors that occur during commissioning or measuring are displayed immediately.
Error messages consist of a variety of icons.
The meanings of these icons are as follows (example):
– Type of error:
S
= System error,
P
= Process error
– Error message type:
$
= Fault message,
!
= Notice message
–
FLOW LIMIT
= Error designation, e.g. measured flow has exceeded the maximum limit.
–
03:00:05
= Duration of error occurrence (in hours, minutes and seconds)
–
#422
= Error number
"
Caution!
• The measuring system interprets simulations and positive zero return as system errors, but displays them as notice
message only.

Faulty connection to PROFIBUS Master
No connection can be made between the PROFIBUS Master and the device.
Check the following points:
Supply voltage
Transmitter
Check the Supply voltage
→
Terminals 1/2
Device fuse
Check device fuse
85 to 260 V AC: 0.8 A slow-blow / 250 V
20 to 55 V AC and 16 to 62 V DC: 2 A slow-blow / 250 V
Fieldbus connection
Check data line:
Terminal 26 = B (RxD/TxD-P)
Terminal 27 = A (RxD/TxD-N)
