Error Diagnosis / Failures and Troubleshooting

General:

The DDLS 170 fulfills the conformity requirements for:

Profibus

INTERBUS

Suconet K

Should errors occur during operation or during commissioning, the DDLS 170 of-
fers a wide range of localization and correction options.

8.1

Errors during commissioning

Voltage supply

polarities correct?

Error

Cause

Correction

Device does not respond
(no LEDs light up)

supply voltage polarity
false, possible line
interruption or loose
contacts on terminal
blocks!

Connect supply voltage
correctly, check lines
and terminal blocks

Coarse adjustment

carried out?

Error

Cause

Correction

Red LED on the remote
multifunction display
blinks

Strength of received
signal insufficient!
Notice: the yellow LED
must light up over the
entire travel area at the
lens end.

Realign the device
(see Chapter 6.2.3)

Fine adjustment

carefully carried out?

Error

Cause

Correction

Less than two green
LEDs light up on the
close-up multifunction
display

Strength of received
signal insufficient!
Notice: As a minimum
the LEDs 1-4 (red) and
LEDs 5-6 (green) must
light up over the entire
travel area

Realign the device
(see Chapter 6.2.3)
