d
The PM electronics is replaced. "-" is dis‐
played instead of the serial number. At
least one AM remains in the device.
Automatic data synchronization
1)
, no
action required by user.
When there are two AMs in the device,
the new PM always synchronizes with
AM1.
The PM receives the data of the previ‐
ously used PM, including its serial num‐
ber
2)
New Un‐
change
d
PM electronics with new serial number is
installed.
Automatic data synchronization
1)
, no
action required by user.
In this scenario, the replacement of the
PM electronics results in a loss of data of
the previously installed PM. In addition,
the serial number is overwritten.
1)
Data synchronization: PM parameters are transferred to the AMx (x=1 or 2), parameters of the AMx are
transferred to the PM
2)
Serial number stored in the PM is also the serial number of the device
