9.6 Control parameters of the load controller

The control parameters can be defined in 3 different ways.
The memory of the load controller contains 5 standard parameter sets.
Depending on the characteristics of the controlled system, a PID triple value can be
selected and activated.
The following standard parameter sets can be selected:
Xp [%]
very fast 42.5
(e.g. for small boilers)
fast 14.5
normal 6.4
slow 4.7
very slow 3.4
(e.g. for large boilers)
Alternatively, the PID parameters can be directly selected and set within the predefined
value range.

ControllerParam
With the method of adapting the control parameters, the characteristic data of the
controlled system are acquired with an adaption procedure whereupon matching PID
parameters are calculated.
If possible, the adaption load should be 100%.
