Adjusting new alarm limits
First select operating mode “Display 2 = Manual control” at the operator panel and then
set the actuator manually to the position of the desired alarm limit.
Then select operating mode “Display 3 = Alarm limits”. Subsequently press the “Up”
(high alarm limit) or “Down” (low alarm limit) button and hold it until the displayed count-
down from 3 to 0 is terminated.
With this procedure you can adjust and save both alarm limits, one after the other. If you
still hold the “Up” or “Down” button after the countdown is finished, “P21” (for the low
alarm limit) or “P22” (for the high alarm limit) is shown by the display for a short time.
Then the alarm limit in %, referred to the stroke of 0...100 %, is shown.
4.2 Operating level 2
You can only access and exit operating level 2 for configuration through special manual
entries.
Calling up operating level 2
1. Press and hold “Up” and “Down” buttons simultaneously.
2. Press “Reset” briefly and release.
3. Wait until displayed countdown from 3 to 0 is finished, then release “Up” and
“Down” buttons.
The display first shows the operating mode (e.g. 2.2) and then a flashing arrow
(siehe Fig. 23).
The arrow indicates that a change-over to operating level 2 is in progress.
If the positioner was working in the mode “Controlling adaptive”, the newly deter-
mined values are saved. This is indicated by the characters “EE” shown on the dis-
play.
