10.10 Replacing a CLV (copying the parameter set)
There are two methods of replacing a CLV and transferring the current parameter set to the
new device:
•
by using the profile bar codes
•
by downloading the parameters from CLV Setup
The parameter set can only be transferred between identical device types (e.g. from one
CLV 420 to another CLV 420, etc.).
10.10.1 Transferring the parameter set using the profile bar codes
To transfer the parameter set using the profile bar codes, you do not need to connect the
device to a PC. The parameter set of the CLV that is to be replaced must be available in the
form of archived profile bar codes or at least as a configuration file in CLV Setup. Otherwise,
the replacement device must be configured from scratch.
The procedure for printing out the profile bar codes is described in
.
1.
Switch off the power supply of the CDB 420 or CDM 420 connection module (of the
CLV).
2.
Disconnect the CLV connector from the CDB 420 or CDM 420 connection module.
3.
Remove the CLV from the bracket.
Before doing so, mark the position and alignment on the bracket/station.
4.
Install, align, and connect the replacement device.
5.
Switch on the power supply to the CDB 420 or CDM 420.
The "Device Ready" LED of the CLV lights up. The CLV outputs a tone to indicate that it
is ready to read the profile bar codes.
6.
Present the first profile bar code
within 5 seconds
.
The CLV confirms that the bar code has been read successfully by outputting a tone via
the beeper and waits
10 seconds
for the next profile bar code.
7.
Present all of the other profile bar codes consecutively in the
printed sequence
.
8.
Then allow the final wait time (10 seconds) to elapse.
The CLV outputs two consecutive tones to indicate that it has switched to Reading
mode.
The new CLV is now ready to use the transferred parameter set.
Troubleshooting
If the software version on the replacement (new) device is older than the version on the old
device (e.g. new device is from warehouse stock), the profile bar codes may contain coded
parameters or parameter values that cannot be interpreted by the older software of the
replacement device. The CLV, however, reads all of the profile bar codes. But this does not
indicate that the CLV can use all the parameters or parameter values.
Use the CLV Setup program to check whether the new CLV is functioning correctly. To
do so, connect the PC to the terminal interface on the CLV. 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.
