2 Introduction
The AT18 comfort lift door drive is an “intelligent” door drive, with which cabin doors and
landing gates can be operated with adjustable speed and acceleration. The
maintenance-free drive unit consists of a direct current motor with a non self locking gear
box that is driven by a controlled rotational speed motor. The power transmission takes
place over a toothed belt. The toothed belt is led across a deflection pulley and can be
equipped with two door pushers. This allows both one-sided as well as central opening
doors to be operated.
The AT18 is currently delivered with the following motor:
- 24V motor, 4.9A for maximum 180 kg total door leaf mass
The door drive can be ordered with various drive pinion mounting positions (on the left or
right, see the diagram in the Appendix).
The door drive does not require a limit switch.
The door width as well as the “OPEN” and “CLOSE” positions are determined
automatically.
A display of the current operating condition is shown via a 7 segment display (H5000) in
the controller.
In the Appendix are all important dimensional drawings, a mounting suggestion and the
ID numbers for ordering the individual drive components.

6 Functions and equipment responses
6.1 Learn and test run
Pushing the Door Parameter button (S5000) causes automatic parameter sensing to
start:
1. Recognition of the motor type
2. Recognition of the door motion direction and the “CLOSE” position
3. Determination of the door system friction values and the door mass.
4. Determination of the door width and the “OPEN” position.Close the door until the
determined door width is travelled and the “CLOSE” position is reached.
At this point the parameters are saved, this takes approximately 3 seconds.
6.2 Door Open command
With the door open command the door opens according to the set travelling curve, as
long as the command is active.
The transitions of the travelling curve (e.g. of acceleration in inertia) are smoothed in
order to avoid noise which would develop due to the play between the cabin and shaft
door. The door reaches the “OPEN” position at creep speed. Afterwards with a queued
up Door Open command the door is kept open by reduced torque.
−The Door Open command must be active during the entire opening travel.
−The Door Open command must be constantly active if in the OPEN position a
continuous toque is to be applied.
−The Door Open command has priority over all other control commands.
6.3 Door CLOSE command
To close the door the Door Close command must be continuously active. After closing,
the door is held closed by reduced torque as long as the Door Close command is active.
6.4 Service button
The door can be opened and closed from the controller with the OPEN (S5001) and
CLOSE (S5002) service buttons. By the operation of these buttons the controller
receives the Door Open or Door Close command respectively in addition to the input
signals on X6.
6.5 Parameter setting
The AT18 terminal module (option), the HT18 user terminal or the FrontEndPC offer
additional adjustment and diagnostic possibilities.
The terminal module is integrated in the housing of the AT18 controller and can be
ordered as an option or added later.
The HT18 user terminal is available separately as an option.
It is attached to X8 of the controller.
It is also possible to use an existing type HT25 user terminal.
The FrontEndPC offers the most comfortable diagnostic possibilities.
A PC can be attached over an USB adapter (option for the FrontEndPC) to X8 of the
controller.

9 Operating instructions AT18 SEDM
NOTE
If the door parameter button (S5000) is pressed while applying the mains voltage, the
current parameters are overwritten at the end of the training run by the factory settings.
If the door parameter button is pressed during normal operation, then only a door width
and a mass determination is performed. The run time curve parameters, force limits and
continuous torque values remain unchanged. Dependent upon the mass determination,
the maximum closing speed as well as the nudge speed is limited.
6.6 Blockage recognition - “CLOSE”
If the door is blocked during a Door CLOSE command while moving in the “CLOSE”
direction, the door then stops and reverses direction.
After reaching the open position the door closes again at normal speed up to approx.
2cm before the obstacle. Subsequently, it moves at decreased speed (initial speed)
against the obstacle and again reverses itself.
This function is continuously performed as long as the obstacle is present.
After the obstacle is removed the door moves at decreased speed to approx. 2cm
beyond the stored position of the obstacle and then continues at normal closing speed
for the remainder of the travel.
6.7 Blockage recognition - “OPEN”
If the door is blocked during a Door OPEN command while moving in the “OPEN”
direction; the door stops.
After approximately 2 seconds the door tries again to reach the open position.
This function is performed a maximum of 3 times.
The door then stops in this position.
If the Door OPEN command is removed, and in the meantime the close command is
activated and the Door OPEN command is re-activated, the door moves at normal
velocity to approx. 2cm before the stored position of the obstacle and then moves with
decreased speed against the obstacle.
Here the door drive stops and repeats the opening sequence 3 times.
If the obstacle was eliminated beforehand, then the door moves with decreased speed to
approx. 2cm beyond the stored blockage position and is driven at normal speed until the
open position is reached.
6.8 Restart after AC power failure
After a mains voltage failure the controller must re-determine the door end positions.
For this the door is driven at decreased speed (initial speed) until the two end positions,
“Open” and “Close”, are recognized by the controller.
Subsequently, the door is again driven at normal speed.

Rev.01 Issue 09/05
10 Operating instructions AT18 SEDM
6.9 Closing force
The closing force can be adjusted between 70 and 230N. When 150N is exceeded a
warning appears on the LCD display of the terminal module (option).
The values mentioned refer to a door that opens to one side; a load cell will only indicate
the half value with central opening doors.
WARNING
During the setting of the closing force the possible effective closing weight must be
considered.
For 1kg of counterweight the desired closing force must be reduced by 10N.
This relates to: - Closing force “CLOSE”
- Closing force “cam distance CLOSE”
- Nudge force “CLOSE”
Example: Closing weight = 4 kg
Desired static force limit “CLOSE” = 150N
The counterweight of 4kg corresponds to a force of 40N. The force limit set must then
amount to 150N - 40N = 110N.
The factory setting is calculated in such a way as to take into account a counterweight of
6kg.
That means it that the resulting static closing force is limited to 90N.
6.10 Emergency rescue
WARNING
An emergency rescue can only be performed if:
– neither a DOOR OPEN nor a DOOR CLOSE command is active,
– the service buttons are not pressed,
– the user terminal or FrontEndPC is not in the menu option high-speed adjustment
or total adjustment (inclusive submenus) position,
– the door has stopped.
Only in these cases is the door drive free of torque. The force necessary to open the
door is below 300 N in accordance with TRA and EN81 requirements.
6.11 Nudging
No reverse is performed during a nudging operation. The DOOR CLOSE and NUDGE
command must be active at the same time. In the case of the recognition of an obstacle
the torque is reduced after 1 second to the limit retaining torque of the motor.
6.12 Light barrier
The input for the light barrier signal has the same function as the DOOR OPEN command.
Exception: The light barrier signal is ignored if the door is opened for less than 1 cm.
If no voltage is present at the light barrier input, this is interpreted as a light barrier
interruption.
The door cannot close.
An interrupted light barrier causes the door to open.
If at the same time a DOOR CLOSE command is active, the door moves toward “OPEN”
until the position of light ray interruption is reached.

Rev.01 Issue 09/05
11 Operating instructions AT18 SEDM
6.13 Emergency power supply (option)
In case of a failure of the mains voltage a battery or a rechargeable battery (e.g. lead gel
rechargeable battery) can be attached to the external emergency power module (option)
and thus makes possible emergency operation.
The door can be opened and closed in this condition; the light barrier input is interpreted.
The movement is thereby limited to a reduced speed (slowendspeedcls or
slowstartspeedop).
When the mains voltage is again present, the controller switches back automatically at
the door end position (OPEN or CLOSE) into normal operation.
CAUTION
The fuse for the emergency power supply, which is installed by the customer, must be a
6 A slow acting fuse.
6.14 Overload protection
If the drive motor is heavily loaded by frequent short DOOR OPEN and DOOR CLOSE
commands quickly following one another, then an automatic extension of the door open
time occurs. The next closing cycle is delayed despite a possible DOOR CLOSE
command; the 7 segment display (H5000) shows “4”.
This function prevents the motor from going into thermal overload.

7 Mechanical assembly and set-up
CAUTION
The safe operation of the lift door drive requires that it is correctly installed and put into
operation by qualified personnel under consideration of the warning references in these
operating instructions.
Before working on the door drive you must ensure that voltage has been removed from
the controller. Only then can you be sure the door is unable to move.
The mechanical assembly and set-up of the lift door drive take place in six steps:
1. Mount the motor onto the motor mount (rubber-bonded metal).
Then, if necessary, mount the motor onto the mounting bracket.
2. If necessary, install the guide roller with mounting bracket.
Pay attention to the adjustment of drive pinion and guide roller; these should align with
each other as exactly as possible (aligning).
3. Bolt the toothed belt together with the door latch and mount.
CAUTION
Only use as door catch (toothed belt lock) the door catch described in the Appendix!
Unsuitable mounting can cause a notch effect on the toothed belts, which can lead to
damage of the toothed belt!
The door catch (toothed belt lock) may not run over the drive pinion or the guide roller!
4. Adjust the toothed belt with the help of the tightener. The correct belt tension is
reached when the toothed belt can be pushed down in the centre approx. 3 cm for each
meter distance between the drive pinion and guide roller.
5. Install the controller in the proximity of the drive motor (consider the cable length).
6. Install the power transformer in the proximity of the controller (consider the cable
length).
CAUTION
If there is a short circuit on the secondary side of the power transformer (defect of the
controller), the temperature of the transformer housing will increase up to over 105°C.
For this reason, the power transformer must be mounted on non-flammable materials.
It must also be prevented that unauthorised people are able to contact the housing.
The service staff is to be instructed.

Rev.01 Issue 09/05

8 Electrical set-up and initial start-up
WARNING
With the operation of electrical equipment inevitably some parts of the equipment contain
dangerous voltage.
Neglecting the operating instructions can therefore lead to severe bodily injuries or
property damage.
Therefore the warnings must be absolutely followed.
During the start-up of the controller (in particular during automatic parameter
determination) the door movements cannot always be externally influenced.
The light barrier is not active during the training run.
An authorized person is therefore required, who is stationed at the door, to guarantee
that during start-up no other person can come into the proximity of the lift door.
The permissible forces and energies are to be checked by the service staff after start-up
on the heaviest door of the overall system (lift).
NOTE
During the parameter training run the motor temperature may not be under 0°C, since
this could cause the value of the door mass to be incorrectly determined and the closing
speed and nudge speed set to a prohibited value.
1. Push the door into the “CLOSE” position.
2. Open the housing cover.
3. Connect motor plug X7.
NOTE
So that no uncontrolled movement occurs during start-up, plug X6 (control inputs) must
not be installed.
4. Connect the input transformer to the mains (230 V AC).
5. Press and hold the red “DOOR PARAM” button (S5000).
6. Connect the output of the mains transformer to X3.
7. Hold the red “DOOR PARAM” button (S5000) until the 7 segment display (H5000)
indicates “_.”.
8. After pushing the brown “OPEN” (S5001) or “CLOSE” button (S5002) the training run
starts. The 7 segment display (H5000) indicates “H.”.
The training run consists of 1 or 2 approximately 10cm opening and closing cycles at
creep speed.
This is followed by a 25cm opening and closing cycle at creep speed that is used to
determine the friction of the door system.
Afterwards the door opens and closes at reduced speed (complete travel). During the
opening cycle, after approximately 10cm of travel, a short acceleration ramp is performed
to determine the mass of the door.
In the “CLOSED” position the door parameters and the calculated door width are saved.
The 7 segment display (H5000) indicates “u”.
9. The door can now be opened with the “OPEN” button S5001.
The 7 segment display (H5000) indicates “o” while the door is opening.
10. Switch off the controller by pulling the input power plug X3.

Changes to the parameters should always be performed in normal operation with the
door in the “CLOSE” position since then the values are then taken over immediately by
the controller.
CAUTION
The maximum static closing force may not exceed 150N including the consideration of
the counterweights!
WARNING
The energies and forces are to be checked by the service
staff after start-up on the heaviest
lift door and to be reduced to the limit values if necessary
.
NOTE
The acquired, optimal parameter settings can be recorded in the adjustment log (see
Appendix adjustment log). This log should also be available when addressing questions
to the Hotline.

9 Relay contacts (option)
The relay contacts are part of the relay module (option) and can be used in order to
report the following door conditions to the main lift controller:
– X11
The door has reached the “CLOSE” position
The relay switches on, when the controller recognizes the “CLOSE” position and no more
impulses are spent by the pulse generator, i.e., the door has stopped. Pin 3 is connected
with pin 1 until the Door OPEN command is activated. The relay then immediately drops
and Pin 3 is again connected with pin 2.
– X12
The door reverses.
The relay switches on, if the door reverses e.g. due to a blockage, a light barrier
interruption or an open command.
Pin 1 is then connected with pin 3 until the “OPEN” position is reached
– X13
The door has reached the “OPEN” position
The relay switches on, if the current distance of the door to the “OPEN” position falls
below 2 cm. Pin 1 and pin 3 are then connected.
When the distance of 2 cm is again exceeded, the relay immediately drops and pin 3 is
again connected with pin 2.
In the “Overview of the control elements” the contacts are represented in a power-off
(inactive) condition.
The active condition is also indicated by an LED on the switched relay.
WARNING
The door controller is not a safety device. Therefore the relay contacts may not be used
for the lift's safety circuit.
With an opened housing cover only low voltage (voltage less than 42V) may be applied
to the controller!
When connecting higher voltages (max. 230V AC) to the relay module, these voltages
may only be turned on if the protective cap is closed and tightened with the mounting
screw.
In this case, the attached wiring must have double or reinforced insulation and only be
stripped directly at the terminal connectors.
The components of the controller and connection cables, as well as the motor plug and
its wiring, may only come into contact with the double or reinforced insulation of the live
wires.
Strain relief is provided by cable ties inside of the protective cap and at the attachment
locations of the housing.

When reversing from the opening to the closing direction the door is braked with the
reversing ramp OPEN_CLOSE and starts the closing movement with the acceleration
ramp CLOSE.

Speed limit curve
The speed limit curve is the characteristic used for the determination of the maximum
permissible door speed V
max
as a function of the total door leaf mass.
In accordance with EN 81 the maximum kinetic energy of the door moving in the closing
direction may not exceed 10 joules. WKIN = 1/2 m ·v ² = 10 J.
Example from following speed limit curve:
Total door leaf mass m = 180 kg = > Vmax = 0.33 m/s.
Figure 3
NOTE
The speed can be adjusted between 0 (corresponds to 0.10 m/s) and 100 %
(corresponds to 0.80 m/s).
