you can refer to the following

table. Typical errors and their possible causes are described here as well as tips for their
elimination.

13.1

General causes of errors

Error

Possible error cause

Measures

Data loss

(DL bit)

Data telegram longer than the bus

telegram in bus cycle/memory size.

Increase in bus telegram length.
Toggle out data earlier.

Data in the RS 232
instead of in the

buffer

Incorrect order.

Correct order:
Provide data, toggle CTB.

PWR

status LED on the circuit board

Off

No supply voltage connected to the device. Check supply voltage.
Hardware error.

Send the device to customer service.

Green/orange,
flashing

Device in boot mode.

No valid firmware, send device to

customer service.

Continuous orange
light

Device error.

Send the device to customer service.

Firmware update failed.

MNS

LED on the housing (see figure 8.1 on page 34)

Green, flashing

Online, no net connection.

Restart if necessary.
