Rescue System - Omron VARISPEED L7 Manual

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.

Rescue Operation Power Supply Ratings
The power supply to the DC bus and to the control card during rescue operation must meet the following
requirements:
Voltage class
When an AC power supply (e.g. a single phase UPS like example 1 or 2 below) is used,
make sure that the rectified voltage meets the voltage range above.
