2 Introduction
The comfort elevator door drive AT40 is an "intelligent" door drive, which is used to drive the cabin and shaft doors as
power-operated protective devices (PL-D) for machines. The 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 AT40 is currently supplied with the following motors:
M2 – 24 V / 1.8 A motor, suitable for a maximum total door panel weight of 120 kg
M3 – 30 V / 4.0 A motor, suitable for a maximum total door panel weight of 180 kg
M4 – 30 V / 4.0 A motor, suitable for a maximum total door panel weight of 400 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. A 7-segment display (H401) 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. These Operating Instructions are valid for devices as from firmware version 1.25.
Note
This manual and these operating instructions are also installation instructions within the meaning of the Machinery Directive
(2006/42/EC).
In the interests of clarity, these Operating Instructions do not contain full details of all information for all product types and
cannot take into account every possible aspect of installation, operation, or maintenance.
You can obtain further information about this product and its application in the Internet (www.siemens.com/sidoor).
Furthermore, the contents of the Operating Instructions shall not become a part of or modify any prior or existing agreement,
commitment, or legal relationship. All obligations on the part of Siemens arise from the relevant contract of sale, which also
contains the complete and solely valid warranty conditions. Any statements contained in these Operating Instructions neither
expand nor restrict the scope of these contractual warranty conditions.
CAUTION
Taking the counterweights into account, the maximum static closing force must not exceed 150 N!
Note
After the optimal settings of the parameters have been determined, they should be noted in the Setting record (Page 44).
This record should also be kept at hand when asking questions on the Hotline.
Note
The power supplies of the system series AT are fitted with an integrally extruded safety plug in line with VDE. This plug must
not be removed (cut off) under any circumstances. The plug forms part of the safety chain of the AT system, in the form of
the "emergency stop" function. The general safety instructions in the Operating Instructions of all AT controllers state that
the system must be disconnected from the mains before starting work on the drive. Permanently connected power supplies,
including those with a separate "emergency stop" switch, represent a change to the device certified according to EN 81/2
and are not permissible. A permanent connection must not be made for the reasons stated, because it cannot be ensured
that the device can be properly disconnected from the mains when required. Changes to the components of the system
series AT, motor, controller or power supply lead to the loss of liability for defects and any claims.
