3) Set both DIP switches S2 to the "ON" position. The HMI must now display the programming
screen of the delay time value, which means the STO90 entered the programming mode
("Config").

4) Set the desired delay time value, e.g. 10 s, as shown below. Then, press the Enter key. At
this point, the display shows momentarily a second screen, indicating that the programming
is being processed by CFW900.
NOTE!
If the programming procedure is aborted at this stage, CFW900 trips fault F160.
To clean this fault, de-energize and re-energize CFW900.
5) If the correct delay time value is displayed on the confirmation screen of the HMI, select
"YES" as shown below. Otherwise, select "NO", which will abort the programming procedure
and trip fault F160.
NOTE!
If the programming procedure stays idle for more than 2 minutes, CFW900 trips
fault F160. To clean this fault, de-energize and re-energize CFW900.
NOTE!
If the programming procedure of the delay time fails or is aborted, the last
programmed value will be kept.
