Changes made for Pathfinder 5226 controllers.

On hydraulic machines letting the oil get overheated can cause problems like damaging seal compounds and accelerate degration of the oil. To keep the oil from overheating too quickly a machine will sometimes be equipped with some form of cooler. Then to know when to turn on the cooler a temperature sensor can be used to get feedback.

The 5226 controller logic uses a temperature sensor to automatically know when to turn the cooler on and off based on the reading. The controller uses 3 parameters to make this logic happen. A Max Hydraulic Oil Temperature, a Hydraulic Oil Cooler Temperature Threshold and a Hydraulic Oil Temperature Hysteresis. The cooler will turn on when the Threshold is reached and stay on until the temperature is lower than Threshold minus Hysteresis. During this time the machine can still be run in Full Automatic. If the temperature reaches the Max then the machine will drop out of run and only jogging will be allowed.
