Override Controls
The DO-4-R-O model includes an output override switch for each output.
The output of the module can be directed from program control to manual
control. The output can be disabled completely as well.
The following describes the actions associated with each position of the override
controls:
ON
The output relay is energized to an ‘ON’ state manually by
setting the switch to ON. Programs have no effect on the output
when the switch is in this position.
OFF
The output relay is de-energized to an ‘OFF’ state manually by
setting the switch to OFF. Programs have no effect on the output
when the switch is in this position.
AUTO
The action of the output relay is determined as a direct result of
program control.
