Command direction priority (PBR)
Name: PBR
Function: Defines the priority of the command direction to determine if the Off
command (ALE) will override the On command (ALA) when both are selected.
Range of values: cmd. priority: off / on
cmd. priority: on / off
Basic setting: cmd. priority: off / on
Command output versions (BAV)
Name: BAV
Function: Defines command output (ALE & ALA) as permanent for latching in the
control system and reversing logic of command output (inversion) for normally
open or fail open valves.
Range of values: pers.cmd:N -- inv.:N -- RT.err--reset:N
pers.cmd:Y -- inv.:N -- RT.err--reset:N
pers.cmd:N -- inv.:Y -- RT.err--reset:N
pers.cmd:Y -- inv.:Y -- RT.err--reset:N
pers.cmd:N -- inv.:N -- RT.err--reset:Y
pers.cmd:Y -- inv.:Y -- RT.err--reset:Y
Basic setting: pers.cmd:N -- inv.:N -- RT.err--reset:N
Meaning:

Max. under voltage time (TUM)
Name: TUM
Function: Defines the max. permissible voltage failure time for automatic
restarting.
Range of values: 0 to 10,000
Meaning: 0 = 0 s (no restart)
10,000 = 1,000 s (adjusting steps: 0.1 s)
