Status output

The status output can be used to show alarm status or to control the dosing and it can be
signaled on Signal Output or Relay Output.
Depending on the Alarm Mode setting, multiple alarms can be signaled on the output and
selected from the alarm class or the alarm item lists.
● Alarm Class: Alarm will be signaled if alarm within the selected alarm class occurs.
● Alarm Item: Alarm will be signaled if selected alarm item occurs. It is possible to select
more multiple alarms to be signaled.
Note
Alarm class
The alarm class options depend on the Alarm Mode setting, either NAMUR or Standard
(Siemens Standard), selected in menu item 3.2.1. Both NAMUR and Siemens Standard
alarms and their messages are described in more detail in Alarms and system messages
(Page 171).
The control output can be used for controlling discrete valve dosing and analog valve dosing
as described in Dosing (Page 149).
