LIFT STANDARD EN 81-20/50
• In case of failure or deactivation of the light curtain, the kinetic energy of the doors must be limited
to 4J. To limit it the lift controller has to activate the slow close input, pin 25, of VF7.
OVERHEATING PROTECTION.
• The internal temperature of the PM motor is measured by the VF7 when the option of “Temperature
measurement” inside the “Programming options” menu is enabled.
DOOR CONTACT.
• A separate monitoring signal is necessary to check that the car door(s) is/are in the closed position.
To comply this point an additional door contact is added, and the signal should be connected to the
lift controller. The maximum contact rating is 2 A 230 V AC.
