Weld Seam Detection System R4000 SND40
for Tubes, Cans and Drums
Error No. Possible cause
via Field bus
20 Data quantity of groups (auto
correlation) does not match.
95 Too much data towards
processor module.
95 System error.
95 Error at data transmission.
95 Error at data transmission.
10 Data speed too high in
x-y operation, or manual
entries during measuring.
11
External 24V are not
recognized.
13 Sensor not connected, sensor
cable defective.
14 Program no. 0 selected.
95
Communication module does
not react or is too slow.
16 AC gain is too large.
17 Manual entries during
measuring.
98 No reproducible tube
circumference signals.
Diameter or speed might be
wrongly entered.
- Fieldbus module not detected.
- Fieldbus communication
blocked for short period, due
to high processor load.
18 Short-circuit
19 Fuse defect
21 Fan no signal

Remedy
Delete program, re-teach.
Check RS232 connection /
Hardware error.
Re-start / Hardware error
Check RS232 connection /
Hardware error.
Check RS232 connection /
Hardware error.
Possible due to system,
Re-start function.
Refrain from entering during
measuring.
Apply 24 V,
replace PM hardware.
Connect sensor.
Select valid program.
Check RS232 connection /
Hardware error.
Adjust gain.
Reduce output voltage if gain
is already to minimum.
Refrain from entering during
measuring.
Correct diameter / speed,
try another tube.
Check Fieldbus module.
Seldom possible due to
system, problem will be
redressed automatically.
Check Fieldbus module, if
frequently occurring.
Check cable or sensor
Check fuse at flux leakage
module
Check fan
