Rescue System
Using rescue operation the car can be moved to the next floor if the power supply fails. In this case the inverter
must be supplied by a UPS or a battery and the rescue operation must be enabled by a digital input (H1- =
85). The DC bus voltage during rescue operation has to be set in parameter L2-11. A light load detection func-
tion can be used to detect the light load direction for the car evacuation.
