2 Technical description

2.1 System description

The door drive LDO AC 3.0 is an "intelligent" door drive. Thanks to this drive, the elevator door may
be opening and closing with regulated speeds and accelerations. The maintenance-free door drive
comprises of a control system which is installed inside a housing, and of a drive in the form of a gear
motor. It uses a standard, alternating current, asynchronous motor with a non-self-locking gear.
Toothed belts are used to transfer the driving force. The drive system can be used for operating a
one-sidedly and centrally-opening doors. The driving motor can be manufactured with differently
installed toothed belt pulleys, for doors opened to the right and to the left. The door drive does not
require an end switch. The door widith and the "open" and "closed" positions are determined
automatically. The door status can be transmitted over to the master elevator control using relay
contacts.

2.2 Functions

Door width determination

Door width determination must be triggered as an automatic process within the framework of
assembly and installation. This operation is described in Chapter „4 Assembly and installation“ .

The „Door opening“ command
The "Door opening" command causes the door to open according to the predetermined motion
curve, as long as the command is present. The "Door opening" command must be present during the
entire opening motion.

The „Door closing“ command
The "Door closing" command causes the door to close according to the predetermined motion curve,
as long as the command is present. The "Door closing" command must be present during the entire
closing motion.

✦

The first closing motion after a power outage takes place at slow speed.
Only if the door commands last a longer time, the door motor remains in the end positions
under an acting moment.
When no holding moment exists in the "Door closed" position (the command "Door closing" is

not present), the door

closes automatically, when it has been opened for more than 3 increments.

Interruption and reversal of the closing motion

There are three different events that lead to interruption and reversal of the closing motion:

• A light barrier attached directly to the door drive signals an interruption of the light ray.

• The door encounters an obstacle during its closing motion.

• The door becomes blocked already in the "open" position.

If any of these three events is detected, the motion taking place shal be briefly interrupted. This
interruption shall be repeated two times and then the door moves to the "Door open" position and
waits 10 seconds. Next, the still present closing command is executed as normal, and the door closes
in the usual manner again. In case of an interruption of the closing command, the pause ends up
immediately.

10/2015 Page 8 of 24

The „Push“ command

In the operational state of pushing, the state of the light barrier attached directly to the door drive is
not observed and the closing speed is lowered. The commands „Push“ and „Door closing“ must be
present simultaneously.

Emergency release

If the door is closed, the emergency release is possible under following conditions:

• when the door is in a standstill,

• no commands from the elevator control system exist, and

• no service button of the door drive was pressed.

When the door was determined to be open byb more than 20 increments (more than 14 mm) from
the "Door closed position", the door recognizes this as emergency release and disconnects the
automatic "Door closing" command.

✦

The force required to open the door is smaller than 300 N.

Light barrier

A voltage ranging from 18 to 27V DC at the light barrier input is interpreted as interruption of the
light ray of the light barrier. This voltage is measured against 24 V GND.
In case of closing door, interruption of the light barrier results in the closing motion being interrutped
and as long as a light barrier command is present, a slow, opening motion is executed.
