Diagnostics and troubleshooting

9.1

General causes of errors

Error
LED MS 34 10x =
"off"
LED MS 34 10x =
"flashes red"
LED MS 34 10x =
"Red, continuous light"
(no communication via
PROFIBUS)
LED MS 34 10x =
"Orange, continuous
light"
Position error

Error on the PROFIBUS

Error
Sporadic errors
on the PROFIBUS
Leuze electronic
Possible error causes
• No supply voltage connected to
the device.
• Device not yet recognized by the
PROFIBUS.
Note: The LED remains off until
the BPS 34 is recognized by the
PROFIBUS. Only after the
PROFIBUS has addressed the
BPS 34 for the first time, the
following state descriptions apply.
• Error on the PROFIBUS.
• Incorrect wiring.
• Wrong termination.
• Incorrect PROFIBUS address set.
• PROFIBUS deactivated.
• Incorrect configuration.
• Parameter memory overflow in
the control.
• Service operation active.
• No bar code tape exists.
• Scanner positioned in total reflec-
tion
• Scanner not properly mounted
Possible error causes
• Incorrect wiring
• Wrong termination
• Electromagnetic influences
• Overall network expansion
exceeded
BPS 34
Diagnostics and troubleshooting

Check supply voltage.

Check PROFIBUS settings.

Reset device
(switch voltage on/off).

Check wiring.

Check termination.

Check PROFIBUS address.

Activate PROFIBUS interface.

Check configuration of the device in the con-
figuration tool.

Reduce number of modules.

Set the service switch in MSD 1 101 to
"Operation".

Check positioning of bar code tape.

Change the angle of the scanning beam by
tilting the BPS 34.

Check mounting.

Check wiring.

Check termination.

Check shielding.

Check grounding concept and connection to
FE.

Check max. network expansion as a func-
tion of the set baud rate.
