Modules with Manual Overrides
The XFR822AU/XFLR822AU Analog Output Modules are
equipped with manual overrides: one rotary knob for each
analog output.
The manual overrides can be set manually to either "auto" or
"0 ─ 110%".
NOTICE
Damage to the electronic module!
► Do not use a tool to adjust the rotary knobs.
► Do not use excessive force. Adjust only by hand.

Synchronization Behavior of Analog Output Module
Configured as Floating Output
In order to regularly update the real actuator position with the
calculated position and thus ensure that the actuator
definitely reaches its end position, a synchronization process
is performed by the Analog Output Module.
During the synchronization process, the Analog Output
Module will continue running for the configured runtime once
it reaches the calculated end position.
This updating (synchronization) is performed:
• If the calculated position of the actuator
< lower synchronization threshold (2 %)
= synchronization towards 0 %
• If the calculated position of the actuator
> upper synchronization threshold (98 %)
= synchronization towards 100 %
• Following any power-up or any reset
