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.
Message

Remedy
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.

loaded"
(Error type: 108)

.
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.
3. "error: external parameters
not valid for device
internal parameters

(Error type: 116)
Start option: S

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 CLX490.
Use the correct external parame-
ter memory or overwrite the cur-
rent one.
4. "error: no external para-
meter memory connected

•
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).
