Equipment Manual, 06/2020, A2B00086683-AD 5
Introduction
1
The comfort elevator door drive AT12 is an "intelligent" door drive with which the cabin and
shaft doors can be opened and closed at adjustable speeds and accelerations. This
maintenance-free drive unit consists of a speed-controlled DC motor with non-self-locking
gearing. The power is transmitted by a toothed belt. The toothed belt passes over a deflector
pulley, and can be fitted with two clutch holders. This enables it to drive both single-sided
and centrally-opening doors.
The AT12 is currently supplied with the following motor:
– 24 V / 1.8 A motor, suitable for a maximum total door panel weight of 120 kg
The door drive can be ordered with the drive pinion either on the left or right-hand side,
please see the drawing in the Appendix.
Operation of the door drive does not require limit switches.
The door width and the "OPEN" and "CLOSED" positions are determined automatically.
An LED display on the controller indicates the current operating states.
The Appendix includes all the important dimension drawings, an assembly suggestion, and
the identification numbers for ordering the individual drive components.

Before commissioning
Please read through these instructions carefully. They contain essential information for the
installation, use and safety of the equipment.
2.1 General safety instructions
WARNING
Only appropriately qualified personnel should work on or in the vicinity of this equipment.
Personnel must be thoroughly familiar with all the warnings, notices, and functions of the
AT12 door controller described in the operating instructions.
In the context of the operating instructions and warning notices, a qualified person is a
person who is familiar with assembling, installing, commissioning, and operating the
product, and who has the relevant qualifications, such as:
•Training, instruction or authorization to commission electric circuits and devices/systems
in compliance with safety engineering standards.
•Training or instruction in the maintenance and use of appropriate safety equipment in
compliance with safety engineering standards.
•Training in first aid measures
The successful and safe operation of this equipment is dependent on proper transportation,
storage, installation, and assembly, as well as on careful operation and maintenance.
Before commissioning, all electrical connections must be inspected to ensure that all contacts
are secure.
Before starting work on the door drive, it must be disconnected from the power supply by
unplugging the power plug.

5.1 Learn and test run
Pressing the learn run button for more than five seconds (S501) executes the automatic
determination of the parameters:
1. Detection of the direction of door movement and the "CLOSED" position
2. Determination of the friction values of the door system and the weight of the door.
3. Determination of the door width and the "OPEN" position. Closure of the door until it has
traveled through the entire determined door width and reached the "CLOSED" position.
These parameters are then saved, which takes three seconds.
5.2 DOOR OPEN command
The DOOR OPEN command opens the door according to the set speed of travel curve as long
as the command is present.
The transitions along the speed of travel curve (e.g. from acceleration to constant velocity)
are smoothed to prevent noises possibly arising from the play between the cabin and shaft
doors. The door reaches the "OPEN" position at creep speed. Then, if the DOOR OPEN
command is present, the door is held open with a reduced torque.
•The DOOR OPEN command must remain present throughout the entire opening
movement.
•The DOOR OPEN command must remain present continuously in order to maintain
continuous torque in the OPEN position.
The DOOR OPEN command has priority over all other control commands.
5.3 DOOR CLOSE command
The DOOR CLOSE command must remain present continuously in order to close the door.
After the door has closed, it is held in this position with reduced torque as long as the DOOR
CLOSE command remains present.
