To...
On
Turn on the output.

Turn off the output.
Auto
Let the control program control the output.
The potentiometer, located between the
Auto-Off-On
switch and the jumper, allows you to manually control the
output level of an analog output. Place the
Auto-Off-On
switch in the
On
position, then turn the potentiometer
counterclockwise to reduce the output, or clockwise to increase the output.
WARNING!
The output potentiometer is NOT used for binary output channels. For a binary output, turn the
potentiometer clockwise until it stops (maximum output) and leave it in this position. Failure to do so may result in
relay-chattering or failure of the relay to energize when the
Auto-Off-On
switch is in the
On
position.
