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.

Functions and device responses
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.

Functions and device responses
5.4 Learn run button
Elevator door drive AT12
16 Manual, 02/2012, A2B00086683A-04
5.4 Learn run button
The learn run button ( S501 ) combines the functions of the automatic learn and test run, and
the option of opening and closing the door from the controller.
The learn and test run is activated by pressing the learn run button for more than five
seconds.
The door can be moved by pressing the learn run button briefly for between 0.1 and two
seconds.
The inputs "Open" and "Close" must not be activated:
● First button press for between 0.1 and 2 seconds in normal or initial operation → door
opens until it reaches the "OPEN" end position, and remains stationary with the average
value of the PWM signal.
● If the button is pressed for between 0.1 and 2 seconds again before the door has
completely opened, the door stops and remains stationary with the average value of the
PWM signal.
● When the button is pressed again for between 0.1 and 2 seconds in normal or initial
operation → door closes until it reaches the "CLOSED" end position, and remains
stationary with the average value of the PWM signal.
● If the button is pressed for between 0.1 and 2 seconds again before the door has
completely closed, the door stops and remains stationary with the average value of the
PWM signal.
● The next button press opens the door again.
● If no buttons are pressed for a period longer than 10 seconds, the next button press for
between 0.1 and 2 seconds always opens the door.
5.5 Parameter settings
The Service Tool and the Sidoor User Software offer additional setting and diagnostic
options.
The Service Tool is available as an extra, separate option.
It is connected to the
X102 connector on the controller.
The Sidoor User Software offers the easiest diagnostic option.
A PC can be connected to
X102 on the controller via the USB adapter (Software Kit
accessory).
Note
The current parameters are overwritten by the factory parameters at the end of the learn run
if the
learn run button (S501) is pressed at the same time as the supply voltage is switched
on.
If the
learn run button is pressed during operation in order to start a learn and test run, only
the door width and weight are determined. The speed of travel curve parameters, force limits
and continuous torques are retained unchanged. The maximum closing speed and the
nudge speed are limited as a function of the determined weight.

Functions and device responses
5.6 Blockage detection "CLOSE"
Elevator door drive AT12
Manual, 02/2012, A2B00086683A-04 17
5.6 Blockage detection "CLOSE"
If the door is blocked in the "CLOSE" direction with a DOOR CLOSE command present, the
door stops and reverses direction.
After reaching the open position, the door closes again at normal speed to within about 2 cm
of the obstacle. It then travels at reduced speed (initial speed) against the obstruction before
reversing again.
This function is repeated continuously, as long as the obstruction remains.
Once the obstruction has been cleared, the door travels at reduced speed to approximately 2
cm past the stored position of the obstruction, and then continues the rest of the way at
normal closing speed.
5.7 Blockage detection "OPEN"
The door stops if it is blocked in the "OPEN" direction with a DOOR OPEN command
present.
After approximately 2 seconds, the door automatically tries to reach its open position again.
This action is repeated a maximum of three times.
The door then remains stationary in this position.
If the
DOOR OPEN command is canceled, the close command given, and the DOOR OPEN
command is then repeated, the door travels at normal speed to within about 2 cm of the
stored position of the obstruction, and then up to the obstruction at reduced speed.
The door drive stops there, and the opening action is repeated another 3 times.
If the obstruction has been removed beforehand, the door travels at reduced speed to
approximately 2 cm past the stored position of the obstruction, and then continues to its
open position at normal speed.
5.8 Nudge
The door does not automatically reverse in the operating state NUDGE . The DOOR CLOSE
and
NUDGE commands must be present simultaneously. When an obstruction is detected,
the torque is reduced after one second to the motor's holding shut torque limit.
5.9 Restart after power failure
After a supply voltage failure, the door controller has to redetermine the end positions of the
door travel. To do this, the door travels on command at reduced speed (initial speed) until
the controller has detected both the
"OPEN" and "CLOSED" end positions. The door then
resumes traveling at normal speed.

Functions and device responses
5.10 Closing force
Elevator door drive AT12
18 Manual, 02/2012, A2B00086683A-04
5.10 Closing force
The closing force can be set between 70 N and 120 N.
Note
The resulting closing force must be checked by a suitable measuring method, and must not
exceed 150 N.
WARNING
When the closing force is set, it is imperative that any effective
closing weight is taken into account.
The desired closing force must be reduced by 10 N for each 1 kg of counterweight.
This concerns the:
•Closing force
"CLOSE"
•Closing force
"Cam distance CLOSE"
•Nudge force
"CLOSE"
Example:
Closing weight = 4 kg
Desired static force limit "CLOSE" = 150 N
The counterweight of 4 kg corresponds to a force of 40 N. The force limit then has to be
adjusted to 150 N - 40 N = 110 N.
The factory setting is designed to take into account a counterweight of 4 kg. This means
that the resulting static closing force is limited to 110 N.
5.11 Emergency release
WARNING
An emergency release can only be actuated if:
•Neither a DOOR OPEN nor a DOOR CLOSE command is present
•the learn run button is not pressed,
•The Service Tool or Software Kit are not in the menu item Quick adjustment or Total
adjustment or one of their sub-menus
•The door has come to a standstill
The door drive is only torque-free if these conditions are fulfilled. According to TRA
(German Technical Rules for Elevators) and EN 81, the force required to open the door
must be less than 300 N.

Functions and device responses
5.12 Overload protection
Elevator door drive AT12
Manual, 02/2012, A2B00086683A-04 19
5.12 Overload protection
If the drive motor is subjected to severe strain by
DOOR OPEN and DOOR CLOSE
commands repeated in quick succession, the hold-open time is automatically increased. The
next closing movement is delayed, even if a
DOOR CLOSE command is present, the LED
flashes red 4 times.
This function prevents the motor from overheating.
