Starting adaption
To start the adaption, proceed as follows:
1
Call up the basic screen.
2
Press the menu field Parameter “Cl2 free”.
3
Press the menu field “Functions”.
4
Press the menu field “Adaption”.
The loop parameters Tu, Ts, Tu
ECO
and Ts
ECO
will be shown.
5
In the menu “Cl2 free – Adaption”, press the “Start” button.
The current phase (13 in total) of the adaption is displayed.
6
Confirm the adaption required with “ADAPTION OK”.
7
Press the Home key and the screen changes to the basic
screen.
Error message during adaption
If adaption is not successful, the error message "ADAPTION?” is
displayed. The reason for this may be problems with the dosing
system or loop times. Errors must be rectified in order to continue
with the adaption. See also “Completing adaption with errors” on
page 34.
Adaption sequence
Each adaption phase is then displayed with a status message:
Various status messages can be displayed, depending on the
selection of the actuator. Different status messages also have dif-
ferent execution times. It is possible that some status messages
are only displayed briefly or not at all if the execution time is very
short.
