Auxiliary Analog Example
The following section outlines an example of setting up the controller to work with a fan that turns on
(Switched Output B) at an engine temperature of 325°F to cool down the engine. The fan won't turn off
until the engine temperature falls below 200°F. The following flowchart depicts the simplified logic
sequence of the controller.
The settings and graph below gives a general idea of how to configure the controller and how it functions.
As you can see the output turns on at 325°F and stays on until it drops below 200°F. The 'Run Time'
shown here is the amount of time the fan was on.
