7.1.6 Cooling Algorithm
The method of cooling may vary from application to application.
For example, an extruder barrel may be cooled by forced air (from a fan), or by circulating water or oil around a jacket. The cooling effect will be different depending on the method. The cooling algorithm may be set to linear where the controller output changes linearly with the PID demand signal, or it may be set to water, oil or fan where the output changes non-linearly against the PID demand. The algorithm provides optimum performance for these methods of cooling.
The type of cooling is set by āPā code P8 ā section 5.2.4.
