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
1. Check the supply voltage → Terminals 1, 2
No display visible and no
output signals present.
2. Check device fuse → Page 156
3. Measuring electronics defective → order spare parts → Page 150
No display visible, but 1. Check whether the ribbon-cable connector of the display module is correctly plugged
output signals are present.
2. Display module defective → order spare parts → Page 150
3. Measuring electronics defective → order spare parts → Page 150
Switch off power supply. Press and hold down both the OS keys and switch on the
Display texts are in a
foreign language. measuring device. The display text will appear in English (default) and is displayed at
maximum contrast.

but no signal at the current
or pulse output
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 → Page 78
• The measuring system interprets simulations and positive zero return as system errors, but displays them as notice
messages only.
Error number: System error (device error) has occurred→ Page 137
No. 001 - 399

Error number: Process error (application error) has occurred→ Page 146
No. 401 - 499
Faulty connection to control system
No connection can be made between the control system and the device.
Check the following points:
