System messages
The CLV490 outputs all system messages in plain text on the auxiliary interface. The mes-
sages are in English and can be displayed in the Terminal Emulator in the "CLV-Setup" pro-
gram.

10.5.1
CLV490 without external parameter memory
10.5.2
CLV490 with external parameter memory connected
In addition to the messages above, the CLV490 also indicates whether it was able to access
the external parameter memory
Message
Meaning
"
CLV490
Soft.Vers. Vx.xx
Aend. Nr. 0000
CLV490
/
OTS
"
The software version and revision is displayed when the power
supply is switched on.
"internal parameters loaded"
When the CLV490 is started, it imports the parameter set that
was last stored permanently in the internal EEPROM to the RAM
"laser safety timeout"
The CLV490 has shut off the laser diode 10 minutes (default set-
ting) after a reading pulse has begun. The reading interval is still
active, even though the CLV490 is no longer reading. The reading
interval has to be terminated by a corresponding pulse signal. The
laser diode is activated again with the next reading pulse.
"no code"
In Reading/Percentage Evaluation mode, the CLV490 indicates
that no codes matching the parameterized evaluation conditions
were detected during the reading interval (error status ST = 2 out-
put on the host interface).
"No ext. parameter memory con-
nected"
No external parameter memory was connected to the CLV490
when it was started.

Message Meaning
"diff. SW version of parameters"
When the CLV490 was started, the software version of the para-
meter set in the external memory was different from that in the
CLV490. The parameter set is still transferred.
"external parameters loaded"
When the CLV490 was started, the external parameter set was
imported successfully to the RAM.
"internal parameters copied to
external memory"
When the CLV490 was started, the internal parameter set was
successfully copied to the external parameter memory.
