4.3.9.8 Display modified parameters
This function is used to display all parameters (regardless of the access stage) that differ from the factory
setting (i.e. plant-specific parameters). This function only works with operator control via the PMU but not with
the OP1S.
Adjustable parameters that have no factory setting (P070) or whose value depends on other parameters
(P071,...) are regarded as "modified".
Those parameters that are dependent on P077 (see Section 4.3.9.1 "Factory setting") whose values differ from
the setting for P077=0 are also regarded as modified.
"Modified" parameters for "special access" are also displayed that are only accessible to specially trained
personnel using P799.
The "Display modified parameters" function can be selected in all operating statuses.

Parameters r990 and r991 provide a list of modified parameters for the PMU and also for the OP1S.

Functions

4.3.10.1

WEA (automatic restart)

The Automatic Restart function can be used for the automatic acknowledgment of faults and automatic restart
of the unit following a power failure (F003, F004, F005, F007, F009 or F010) without the operator having to
intervene.
The common rectifier will react according to the selection below in the following scenarios: If the voltage fails at
one of the connections 1U/L1, 1V/L2, 1W/L3, X9.1, X9.2 or if its values are not within the permissible tolerance
range and if the period of so-called "self-synchronous operation" (see further down) has expired and if the DC
link voltage has dropped below the threshold P074 * 1.35 * P071:
P366 = 0 : WEA (automatic restart) is inhibited
No automatic restart; the relevant fault message (F003, F004, F005, F007, F009 or F010) is
initiated..
P366 = 1 : Acknowledgment of power failure after system recovery
The common rectifier enters the operating status o 008 (Switch-on inhibit) or o 009 (when switching
on/off with the I/O keys of the PMU). On power recovery, a new ON command must be given to
enable the DC link to re-charge. The converter is not automatically restarted by the WEA function.

Common Rectifier Operating Instructions
(P052 = 22)
Select the "Display modified parameters" function
Only parameters that differ from the factory setting appear on the PMU (i.e.
plant-specific parameters), irrespective of the access stage (P051). It is not
possible to modify the parameter value here.
