8.3.3
Messages for errors accessing the external parameter memory
(connector cover)
The CLV490 outputs further error messages, in addition to the general error messages in
Chapter 8.3.1 CLV490 without external parameter memory, Page 8-2
if problems arise
when the external parameter memory is accessed.
Message
Meaning
Possible cause
Remedy
1.
"error: access to external
parameters not successful,
internal parameters
loaded"
(Error type: 104, 105,
106, 111, 112,115)
•
Start option: S

-
TERNAL
P
ARAMETERS
.
The CLV490 has
not
loaded
the external parameter set.
Instead, it has loaded the in-
ternal parameter set to its
RAM.
The CLV490, however,
does not output data on the
host interface.

XTERN
.
The CLV490 was
not
able to
copy the internal parameter
memory. It has loaded the in-
ternal parameter set to its
RAM.
The external parameter memory is
defective.
Repeat the startup procedure. If
the error is still present, contact
the SICK Service department.
2.
"error: external parameter
memory full,
internal parameters
loaded"
(Error type: 108)
Start option: S
TART
WITH
C
OPY
I
NTERN
–> E
XTERN
.
The CLV490 was
not
able to
copy the internal parameter
memory. It has loaded the inter-
nal pa-
rameter set to its RAM.
The internal parameter set is too
large for the external memory
(memory is full).
Contact the SICK Service depart-
ment.
3.
"error: external parameters
not valid for device,
internal parameters
loaded"
(Error type: 116)
Start option: S
TART
WITH
E
XTER
-
NAL
P
ARAMETERS
.
The CLV490 has
not
loaded the
external parameter set. Instead,
it has loaded the internal pa-
rameter set to its RAM.
The CLV490, however, does
not output data on the host
interface.
The parameter set in the external
memory is not from a CLV490.
Use the correct external para-
meter memory or overwrite the
current one.
4.
"error: no external para-
meter memory connected,
internal parameters
loaded"
(Error type: 102)
•
Start option: S

The CLV490 has

The CLV490 was
not
able to
copy the internal parameter
set to the external memory. It
has loaded the internal para-
meter set to its RAM.
•
External parameter memory not
connected.
•
External parameter memory not
connected.
•
OK if the device is to be oper-
ated without an external
parameter memory.
•
Check whether the memory is
connected correctly (free
wiring: check wire assignment).
