Fig. 47. Manual overrides (toggle switches)
The …R824A Relay Output Modules are equipped with
manual overrides: one for each relay output. These sliding
switches can manually be set to either "auto" or "0" or "1".
Manual Override in the AUTO Position
When a manual override of the …R824A Relay Output
Module is set to the “AUTO” position, and the corresponding
relay output has been configured, the following applies:
 If the L
ONWORKS network is functioning properly, the
logical status of the relay output will be “AUTO.”
 If the L
ONWORKS 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 …R824A 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 L
ONWORKS 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 L
ONWORKS network:
nvoDoActPosnFb[ ] will have a value of 0% and a state of
0.
 The status LED will be dark.
Manual Override in the ON Position
When a manual override of the …R824A 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 100…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 …R824A 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.”
