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' set‐
ting.
ALL
You have a positioner with the "Fail in Place" function, article number
with order suffix -Z F01.
● Std
● FIP
You only require this parameter for servicing if the basic electronics
has been replaced.
If you order a positioner for Fail in Place applications, it is then
equipped with a special pneumatic block. The "PNEUM" parameter
is preset to "FIP".
When you replace the basic electronics, you have to set the pneu‐
matic type:
1. Set the "49.PNEUM" parameter from "Std" to "FIP".
2. Set the "'51.FSTY' Safety position (Page 171)" parameter to
"FSSP" so that the positioner retains the current position even
following switching on again.
