Parking [335]
Parking is a function, which automatically deactivates the START, if the parking
conditions Depark. hyst. [341] (page 68) and Parking time [347] (page 68) are met.
If the PC operates at its low limit for the time Parking time [347] (page 68),
converter blocks the START. This can occur if the controlled quantity exceeds the
setpoint value and the PC output is at minimum. If the regulation error changes so it
exceeds the value Depark. hyst. [341] (page 68), the START block will be undone
and PC starts to regulate. This function is used to prevent unnecessary operation of
the device and saving the energy when the regulation has no major impact on the
controlled quantity.
