To use the Auto-Off-On switches
You can control an output using the Auto-Off-On switch.
Set the switch to...
On
Off
Auto
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.
