Electrical power supply
•
The electrical power of the system, terminals 32-33, must be connected to a 24 V
DC
SELV/PELV source.
•
Terminals 34-35 are used for battery power, when the main power fails, to prevent the safety
gear from engaging. These same terminals are also used for charging the battery, so no
intermediate charger need be connected.
External battery
charger
Do not connect a charger between the batteries and the SD-
BOX, as it may burn.
Necessary input signals from the lift
•
DOORS, terminals 49-50, to indicate the doors are closed. The car door must be connected
in series with the floor doors. The input allows the use voltages from 24 to 230 V
DC/AC
.
•
MOTOR, terminals 53-54, to indicate the motor is running. A lack of voltage means the
machine is not working. The input allows the use voltages from 24 to 230 V
DC/AC
.
•
Unlocking zone (LEVEL1/LEVEL2), terminals 22-23 LEVEL1 and 24-25 LEVEL2. This

implement a manual rescue or bypass command. If there is a voltage applied for more than
3 seconds, the overspeed governor will be unlocked. The input requires a 24 V
DC
signal,
whose use is optional. The bypass can be performed using the “MANUAL
RESCUE/BYPASS” button on the SD-BOX.
•
Remote reset signal (EXTERNAL RESET)
, terminals 20-21, to implement the reset
command from the control panel. If there is a voltage applied, the reset function must be
performed. The input requires a 24 V
DC
signal, whose use is optional. The bypass can be
performed using the “RESET” button on the SD-BOX.
