Troubleshooting instructions
Always start troubleshooting 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.
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
→
order spare parts
3.

Error messages on display
Errors which occur during commissioning or measuring operation are displayed immediately. Error messages consist of a
variety of icons. The meanings of these icons are as follows (example):
– Error type:
S
= system error,
P
= process error
– Error message type:
$
= fault message, ! = notice message
–
EMPTY TUBE
= Type of error, e.g. measuring tube is only partly filled or completely empty
–
03:00:05
= duration of error occurrence (in hours, minutes and seconds)
–
#401
= error number
"
Caution!
• Also refer to the information on
• The measuring system interprets simulations and positive zero return as system errors, but displays them as notice
messages only.
Error number:
No. 001 - 399
No. 501 - 699
System error (device error) has occurred
Error number:
No. 401 - 499
Process error (application error) has occurred
