Text of error message
Error No.
via Field bus
Possible cause
Remedy
Invalid groups.
20
Data quantity of groups (auto
correlation) does not match.
Delete program, re-teach.
PM: receive buffer overflow.
95
Too much data towards
processor module.
Check RS232 connection /
Hardware error.
System error.
95
System error.
Re-start / Hardware error
PM: message error - no STX.
95
Error at data transmission.
Check RS232 connection /
Hardware error.
PM: char not received in hex.
95
Error at data transmission.
Check RS232 connection /
Hardware error.
PM: message checksum error.
PM: message ID not in hex.
PM: message length invalid.
PM: unknown message ID.
PM: unexpected message.
PM: XY data transfer to slow.
10
Data speed too high in
x-y operation, or manual
entries during measuring.
Possible due to system,
Re-start function.
Refrain from entering during
measuring.
SPS: 24V power supply error.
11
External 24V are not
recognized.
Apply 24 V,
replace PM hardware.
PM: Sensor cable error.
13
Sensor not connected, sensor
cable defective.
Connect sensor.
SPS: Selected program number 0 is
invalid.
14
Program no. 0 selected.
Select valid program.
PM: transmit buffer overflow.
95
Communication module does
not react or is too slow.
Check RS232 connection /
Hardware error.
PM: AC overdrive.
16
AC gain is too large.
Adjust gain.
Reduce output voltage if gain
is already to minimum.
PM: Data transfer too slow.
17
Manual entries during
measuring.
Refrain from entering during
measuring.
PM: Speed measurement not possible.
98
No reproducible tube
circumference signals.
Diameter or speed might be
wrongly entered.
Correct diameter / speed,
try another tube.
PM: Error bus module.
-
Fieldbus module not detected.
Check Fieldbus module.
PM: Bus transfer fault.
-
Fieldbus communication
blocked for short period, due
to high processor load.
Seldom possible due to
system, problem will be
redressed automatically.
Check Fieldbus module, if
frequently occurring.
PM: Short-circuit at sensor
18
Short-circuit
Check cable or sensor
PM: Flux leakage module defect
19
Fuse defect
Check fuse at flux leakage
module
PM: Fan defect
21
Fan no signal
Check fan
