Error messages
If errors occur accessing the external parameter memory, the CLV outputs error messages
on the terminal interface. When the CLV is
started
,
these messages can be displayed using
the "CLV-Setup" program.
1.
Connect the PC to the terminal interface on the CLV using an RS 232 cable (AMV/S 60:
connect the PC to the internal 9-pin Service plug).

2.
Switch on the PC and start Windows.
3.
Start the "CLV-Setup" program and open the Terminal Emulator.
4.
Choose the extended display mode.
5.

op-
tion (default). This is the case when the device is put into service for the first time, e. g. when
it is taken from the warehouse. The device must be replaced with a device of the same type.
You do not need to connect a PC to replace the device.

Chapter 10.12.2 Importing the parameter set from
the external memory, Page 10-70
The CLV imports the external parameter set into the RAM. This is sufficient to ensure that
the device operates correctly. If the parameter set is to be stored permanently in the CLV
(EEPROM), a PC with the "CLV-Setup" program must be connected to upload the parameter
set from the CLV to CLV-Setup and then download it again to the CLV with the P
ERMANENT
storage option. When asked to do so, adjust the external memory again.
