3element continuous controller setup
1. Press the button Cont. controller in the menu 3element contr. setup .
2. The name of the controller is
highlighted in yellow.
3. The green input fields
Qty. of steam, Water
flowrate
and
Level
show the signals that
have been set. Select the input field to show
all established signals.
4. Select the signal that is to provide the
measured value.
5. The green input field Rating shows the
value that has been set. To change this,
select the input field. The value rates the
influence of the difference (steam and water
flowrate) on the measured level signal.
6. The current value appears in the input mask.
The on-screen keyboard can be used to modify this.
7. To toggle the setpoint between Internal and External, press the button
Internal setpoint /
External setpoint
.
8. To enter a signal for an external setpoint, select the green input field. All established sensing ele-
ments will be indicated.

position feedback signal, select the green input field. All signals that have been set may be se-
lected.
10. The green input field

nal for the manipulated variable, select the green input field. All signals that have been set may
be selected.
11. The green input field

displays the current value. To change the value, select the input field.
12. The green input fields Limit min/max show the current limit values for the manipulated variable.
Select the relevant input field to enter or change the value.
13. The green input field Deadz. min/max indicates an actual value zone of the controller where the
controller delivers an unaltered manipulated variable. To enter or change the value, select the
input field.
Note
Controlled actual value = Level – (Qty. of steam – water flowrate) x Rating (only when
Qty. of steam – Water flowrate > 0).
If the signal for steam quantity or water flowrate is faulty, the controller will only use the
Level actual value.
