8.4.2.20 '50.PRST' Preset
Possible settings: ● ALL
● Init
● PArA
● diAg
Purpose: Use this parameter to restore the factory settings for most parame‐
ters. The following parameter groups are available:
● ALL: Reset all parameters together which can be reset by 'Init',
'PArA' and 'diAg'.
● Init: Reset initialization parameters '1.YFCT' to '5.INITM'.
● PArA: Reset application parameters '6.SCUR' Current range of
setpoint (Page 147) to '49.\\LIM' Response threshold of fault
message 'Control deviation' (Page 159).
● diAg: Resetting the extended diagnostic parameters A to U
(Page 163) as well as parameter '52.XDIAG' Activating for ex‐
tended diagnostics (Page 162).
An overview of the parameters and factory settings can be found in
section Tabular overview of the parameters (Page 135).
In order to select one of the parameter groups listed above, repeat‐
edly press the button until the desired setting is output in the
display. Start the function by keeping the button pressed until
'oCAY' is output in the display. The values of the parameter group
are now the factory settings.
Description: If you wish to use a previously initialized positioner on a different
control valve, set the parameters to the factory settings prior to a
new initialization. To do this, use the 'ALL' or 'Init' setting.
Restore the factory settings if you have changed several parameters
at once without being able to predict their effect and the undesired
reactions which may occur as a result. To do this, use the 'ALL'
setting.
Factory setting: ALL
