Detailed fault analysis

Communication errors can occur when transmitting telegrams to the NAV245. The NAV245
then returns an error code which you can evaluate (see “Telegram listing NAV245”,
part no.: 8018823).

Fault

Possible cause

Corrective measure

All LEDs are dark and
the scanner head
does not rotate.

•

No supply voltage at the
terminals

▸

Check the supply voltage (see
Section 10.1 “NAV245 data sheet” on
page 72).

▸

Check whether supply cables are fixed
correctly in the connector plug.

▸

Check whether the cables are poled cor-
rectly.

No LED lights up.
The scanner head
only rotates briefly.

•

Supply voltage too low

▸

Increase the wire cross-section.

SOPAS ET cannot
communicate with
the NAV245.

•

Supply voltage to the
NAV245 not switched on

•

PC not connected to the
NAV245

•

Incorrect interface
selected

•

Another application on
the PC is already
accessing the interface

•

Order when switching on
the NAV245 and the
connected PC not
adhered to

▸

See fault 1, 2, and 3.

▸

Connect the PC to the NAV245 (use the
corresponding data cable depending on
the type of interface).

▸

Select the interface in SOPAS ET in
accordance with the connection made
on the PC.

▸

Check the pin assignment of the inter-
face, end the corresponding application
if necessary.

▸

1. Switch on the PC, 2. connect the PC
with the NAV245, 3. switch on the
NAV245.

Measurements in
close range without
objects present.

•

Contaminated or
scratched lens

▸

Carefully clean the lens with a soft,
lint-free cloth.
If the lens is scratched, contact SICK
Service.

The NAV245 does not
detect objects that
are present.

•

Smoke and dust

▸

Check whether the scanner head is
clean and dry.

The NAV245 does not
transfer any
measurement results.

•

Wiring error in the data
connection.

▸

Check wiring.

Frequent CRC errors
via the RS-232
interface.

•

Data transmission time-
critical

▸

Increase the baud rate.
