8.3.3
Messages for errors accessing the external parameter memory
The CLX outputs further error messages, in addition to the general error messages in
Chapter 8.3.1 CLX without external parameter memory, Page 8-2
,
if problems arise when
the external parameter memory is accessed.

1. "error: access to external
parameters not successful

The CLX has
not
loaded the
external parameter set. In-
stead, it has loaded the inter-
nal parameter set to its RAM.
The CLX, however, does not
output data on the host in-
terface.

The CLX was
not
able to copy
the internal parameter me-
mory. It has loaded the inter-
nal 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 empty
internal parameters
loaded"
(Error type: 103)

.
The CLX has
not
loaded the
external parameter set. Instead,
it has loaded the internal para-
meter set to its RAM.
The external parameter memory is
empty.
If the device is being used for the
first time, data must first be
loaded to the external parameter
memory. See
3. "error: external parameter
memory full
internal parameters
loaded"
(Error type: 108)

XTERN
.
The CLX was
not
able to copy
the internal parameter memory.
It has loaded the internal para-
meter set to its RAM.
The internal parameter set is too
large for the external memory
(memory is full).
Contact the SICK Service depart-
ment.
4. "error: external parameters
not valid for device
internal parameters
loaded"
(Error type: 116)
Start option: S

WITH
E
XTER
-
NAL
P
ARAMETERS
.
The CLX has
not
loaded the
external parameter set. Instead,
it has loaded the internal para-
meter set to its RAM.
The CLX,
however, does not output
data on the host interface.
The parameter set in the external
memory is not from a CLX 490.
Use the correct external parame-
ter memory or overwrite the cur-
rent one.

•
OK if the device is to be opera-
ted without an external para-
meter memory.
•
Check whether the memory is
connected correctly (free
wiring: check wire assignment).
