1.3.1

Safety system architecture

The safety system architecture varies depending on elevator version.

Elevators require motor supply voltage and permanent 24V DC power sup-
ply for communication devices. Motor supply voltage depends on version
(50 Hz version: 400 V AC, 60 Hz version: 480 V AC).

Safe 24V DC (disconnected at emergency) is not used although the eleva-
tor provides means for passing on the power.

1.3.1.1

Profibus/DeviceNet versions

Emergency switch

The purpose of the safeguard is to be part of the line global emergency
safety system and affect the motor power supply to the elevator.

In case of emergency, the motor power supply to elevator shall be discon-
nected (stop category 0, EN60204-1).

Door switch

The elevator is equipped with a service door for access inside. Opening the
door results in a elevator internal disconnection to motors (stop category 0,
EN60204-1).
