6.2 Parameter
1. INIA
Automatic initialization (cap.5.3.2 selecting a configuration parameter
)
Selecting "STRT" and pressing the button for at least 5 seconds starts the automatic initialization. The initialization
process is indicated by "RUN 1" to "RUN 5".
2. INIM
Manual initialization (ch. 5.3.3 Changing a parameter)
Selecting "STRT" and pressing the button for at least 5 seconds starts the manual initialization.
3. RESERVE
…
4. TYPE
Type of actuator
The actuator is a rotary actuator (TURN) or linear actuator (LINE).
5. RESERVE
6. DEBA
dead band of the controller with this parameter, you can constantly adjust the dead tape in automatic
mode to the requirements of the control circuit via the setting "DEBA = AUTO". When a control oscillation
is detected, the slider gradually increases the dead tape. The reverse adaptation is carried out by a time
criterion. With the values 0.1 to 10.0, the dead band is set firmly. The value is a percentage. This allows
control vibrations to be suppressed. The control accuracy improves the smaller the dead tape.
7. DEBA1
dead band of the controller 1
If the parameter
DEBA1 = AUTO is set, it inherits the values of the parameter DEBA, which
changes according to the operating conditions during the running process. If the control vibration
causes changes in the valve position (e.g. pipe leakage), the corresponding increase of the DEBA1
can be mitigated.
If the DEBA1 parameter has different values, the dead band 1 of the controller is a specified value
8. PRST
default (reset to factory setting)
Factory setting and reset initialization.
Note
The positioner must be reinitialized after the preset. All previously determined
maintenance parameters are deleted.
