Manual Override in the AUTO Position
When a manual override of the …R824 Relay Output
Module is set to the “AUTO” position, and the corresponding
relay output has been configured, the following applies:
 If the LONWORKS network is functioning properly, the
logical status of the relay output will be “AUTO.”
 If the LONWORKS network is not functioning properly, the
feedback signal will be switched to the safety position
value.
 The feedback signal on the LONWORKS network:
nvoDoActPosnFb[ ] will have a value of either 0% or
100%, and a state of -1.
 The status LED (yellow) will indicate the actual logical
state of the relay output as commanded (by
nviDoSwitch[ ]).
When a manual override of the …
R824 Relay Output
Module is set to the “AUTO” position, and the corresponding
relay output has
not been configured, the following applies:
 Regardless as to whether the LONWORKS network is
functioning properly or not, values from the L
ONWORKS
Bus will be ignored, and there will be no heartbeat or
safety position.
 The feedback signal on the LONWORKS network:
nvoDoActPosnFb[ ] will have a value of 0% and a state
of 0.
 The status LED will be unlit.
Manual Override in the ON Position
When a manual override of the …R824 Relay Output
Module is set to the “ON” position, the following applies:
 If the relay output has been configured, its logical state
will depend upon the actual output configuration.
 If the relay output is unconfigured, it will be switched ON.
 Regardless of configuration, the feedback signal on the
L
ONWORKS network: nvoDoActPosnFb[ ] will have a
value of 1000…0% and a state of -1.
 Regardless of configuration, the status LED (yellow) will
flash to indicate “manual override.”
Manual Override in the OFF Position
When a manual override of the …R824 Relay Output
Module is set to the “OFF” position, the following applies:
 If the relay output has been configured, its logical state
will depend upon the actual output configuration.
 If the relay output is unconfigured, it will be switched
OFF.
 Regardless of configuration, the feedback signal on the
L
ONWORKS network: nvoDoActPosnFb[ ] will have a
value of 0% (direct) or 100% (reverse) and a state of -1.
 Regardless of configuration, the status LED (yellow) 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.
