procedure:
• Perform the automatic adjustment (
X.TUNE) of the process controller.
• Add the F.CONTROL auxiliary function to the main menu using the
configuration menu ( ADDFUNCTION) and make settings.
• Make settings in the BUS.COMM function.
• Configuration of the process values.
13.1. settings in BUS.COMM
Address 0
Enter a device address (value between 0 and 126)
BUS FAIL Activate or deactivate approach of the safety
position
SafePos off
The actuator remains in the position which cor-
responds to the set-point value last transferred
(default setting).
SafePos on
If there is a fault in the bus communication, the
behavior of the actuator depends on the acti-
vation of the
SAFEPOS auxiliary function.
SAFEPOS activated:
The actuator moves to the safety position which is specified in the
SAFEPOS auxiliary function.
SAFEPOS deactivated:
The actuator moves to the safety end position which it would
assume if the electrical and pneumatic auxiliary energy failed.
See Chapter “15. Safety end positions”.
