Override Controls
The AO-4-8-O model includes an output override switch and manual variable
voltage control 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:
MANUAL
The analog signal generated by the module is controlled
manually by adjusting the ADJUST potentiometer below to the
manual override switch. Programs have no effect on the output
when the switch is in this position.
OFF
The output is disconnected. Programs and the setting on the
ADJUST potentiometer have no effect on the output Device
when the switch is in this position.
AUTO
The analog signal is generated as a direct result of program
control. The setting on the ADJUST potentiometer has no effect
on the output Device when the switch is in this position.
ADJUST
This is a variable control that allows you to manually adjust the
output of the analog signal when the override switch is in the
MANUAL position. Insert the tip of a small screwdriver to use this
control. Turning to the right (clockwise) increases the output.
Turning left (counterclockwise) decreases the output.
