Fig. 68. Manual overrides (rotary knobs)
The XFR822/XFLR822 Analog Output Modules are
equipped with manual overrides: one for each analog
output. These rotary knobs can be manually set to either
"AUTO" or "0...100%" (infinitely adjustable).
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.

Manual Override in the AUTO Position
When a manual override of the XFR822/XFLR822 is set to
AUTO, and the corresponding analog output has been
configured, the following applies:
0(2)...11 V (default)
max. ±1 mA
8 bit
±150 mV
< 200 mV
Short-circuit protected;


If the L W
ON
output voltage of the analog output will be as
commanded.

If the L W
ON
output voltage of the analog output will be the safety
position value.

The brightness of the status LED (red) of the analog
output will be proportional to the commanded output
signal.
When a manual override of the XFR822/XFLR822 is set to
AUTO, and the corresponding analog output has not been
configured, the following applies:

Regardless as to whether the L
functioning properly or not, the output voltage of the
analog output will be 0 V (values from the L
Bus will be ignored, and there will be no heartbeat or
safety position).

The feedback signal on the L
nvoAoActPosnFb[ ] will have a value of 0% and a state
of 0.

The analog output status LED will be unlit.
Manual Override in the Override Position (0...100%)
When a manual override of the XFR822/XFLR822 is set to
0...100%, and the corresponding analog output has been
configured, the following applies:

The output voltage of the analog output will be 0...10 V
(direct) or 10...0 V (reverse).

The feedback signal on the L
nvoAoActPosnFb[ ] will have a value of 0...100% and a
state of -1.

The status LED (red) of the analog output will flash to
indicate "manual override."
When a manual override of the XFR822/XFLR822 is set to
100
0...100%, and the corresponding analog output has not
been configured, the following applies:

The output voltage of the analog output will be 0...10 V.

The feedback signal on the L
nvoAoActPosnFb[ ] will have a value of 0...100% and a
state of -1.

The status LED (red) of the analog output will flash to
indicate "manual override."
Note
Panel Bus I/O modules feature watchdog functionality. Con-
sequently, if the module's firmware stops running (due, e.g.,
to updating), the watchdog will switch OFF the module's
outputs – even if the corresponding manual overrides (if
present) have been set to ON. Thus, the manual overrides
should NOT be thought of as emergency overrides; rather,
they are subordinate to the given Panel Bus I/O module's
processor and firmware.
Analog Outputs Configured as Binary Outputs
Using CARE, the analog outputs can be configured
individually as binary outputs. The voltage output is then 0 V
or 10 V, depending upon the signal from the controller.
