OUTPUT OVERRIDE
HOA
variants (
CBXi-8R8-H
,
FLX-4R4-H
and
FLX-8R8-H
) include hardware override switches for each of
their outputs. The override controls are located behind the flap on the front of the device:
CBXi-8R8-H
FLX-4R4-H
FLX-8R8-H
These controls consist of a switch and a rotary knob for each output:
The channel number corresponding to the switch is shown directly below the switch.
The switch can be set to one of 3 positions:
When a switch is set to the
Centre position
the corresponding output channel is set to
Auto
mode
–
the output is controlled by strategy.
The rotary knob has no effect in this mode.
When a switch is set to the
Bottom position
the corresponding output is forced to
Off
–
both the strategy setting and the rotary knob have no effect.
When a switch is set to the
Top position
the corresponding output is set to
Manual
mode
•
for digital outputs, the output is forced
on
•
for analog outputs the rotary knob setting controls the output value.
Note
: Manual position is supervised, i.e. the
strategy
is aware of the manual value.
The
Controller Strategy
can determine if an override is in place is by connecting to the
Override
point on the
output module:
The value of the
Override
point will be '
0
' when the output is active and ‘
1
’ when the point has been
manually overridden. This allows the
strategy
to react to the fact that a point has been overridden.
Note
: The corresponding terminal LED will indicate the override condition.
