Adaption / self-setting of PID controller parameters

The load controller integrated in the LMV5 is capable of identifying the controlled
system, of calculating its PID parameters based on the acquired characteristic data,
and of resetting the parameters. In modulating mode, the adaption function is available
for both temperature and pressure control. In multistage mode, the PID controller is
active, which means that no adaption can be made there.
Preconditions for adaption to be started:
∂
Boiler / combustion plant has fully reached the operating temperature
∂
Actual value lies 10...20% below the setpoint
Adaption can be activated in different ways:
1. Adaption from manual operation:
a) Adaption from shutdown or standby Manual
b) Adaption from startup or operation Manual
2. Adaption from automatic operation:
a) Start of adaption from shutdown or standby
b) Start of adaption from startup or operation
If adaption is not successful due to high burner output, the adaption load can be
reduced.
