Appendix
¾
Check whether all of the parameter settings used are necessary to configure the CLV
for the current reading application. If necessary, replace the software version in the new
device.
If the software version on the new device is more recent than that on the old one, the default
settings in the imported parameter set will include parameters that were not contained in
the old version.
¾
Upload the parameter set and check whether the new parameters are relevant for con-
figuring the CLV for the current reading application. If necessary, change the parameter
values and download the parameter set to the CLV again. Save the new parameter set
as a configuration file in CLV-Setup.

10.12.2 Importing the parameter set from the external memory
A PC does not have to be connected to import the parameter set from the external memory.
The parameter set in the external memory must contain an up-to-date copy of the set used
by the CLV that is to be replaced. Otherwise, the replacement device will import a different
parameter set to its RAM when it is started. The start option in the device must be set to

. This is the default setting.
1.
Switch off the power supply to the AMV/S 60 Connection Module (of the CLV).
2.
Remove the connector cover (containing the parameter memory) from the CLV.
3.
Remove the CLV from the bracket.
Mark the position and alignment of the CLV on the bracket station.
4.
Mount the connector cover on the terminals correctly and screw it into place.
5.
Mount and align the replacement device.
6.
Switch on the power supply to the AMV/S 60.
The CLV starts and loads the parameter set from the external memory to the RAM.
The "Device Ready" LED blinks for approx. 10 s and then lights up constantly.
The parameter set is transferred temporarily to the replacement device. It is lost when the
device is switched off but is loaded again from the external memory the next time the CLV
starts.

Troubleshooting
If the software version on the replacement device is older than that of the parameter set in
the external memory (e. g. if the replacement device originated from the warehouse), the
loaded parameter set may contain parameters or parameter values that cannot be interpre-
ted by the older software. In this case, the "Device Ready" and "Read Result" LEDs blink
together for approx. 10 s, after which the "Device Ready" LED lights up constantly. See also
Chapter 10.6.8 Unknown parameters, Page 10-47
.
If the software on the replacement device is newer than that of the parameter set in the
external memory, the parameter set loaded from the external parameter memory to the
replacement device will contain new parameters that are set to the default values.
