Service manual

P, I, D
Controllers PID factors (kP, kI, kD), determining how “strong” influence has each of the regulators members.
Integral windup
Maximum saturation of integral element of PID regulator.
Feedback +,-
Maximum and minimum values by which can the PID algorithm change the DC of the electric valve defined in
the Boost DC Table.
Diagram of connecting the electric valve
Connecting the electric valve should look as follows:
The diagram below presents the method of connecting the three way valve used for controlling the boost of
turbochargers with an internal wastegate.
The presented valve is opened between the stubs 2-3 if it is unpowered. In case of powering the connection
between stub 1-2 is open.
For the above mentioned connection 0% of duty cycle gives minimal boost defined by the actuator, 100% of dc
causes maximum boost that can be achieved by the turbocharger.
