Operating Manual - Elevator Door Operation AT18

2 Introduction

The comfort elevator door driver AT18 is an "intelligent" door driver with which cabin and shaft
doors can be operated with adjustable speed and acceleration settings. The maintenance-free
power unit consists of a DC-motor with non-self-locking gears and is operated speed-controlled. The
power transmission takes place with a timing chain. The timing chain is fed through an overhead
pulley and can be equipped with two door clutch holders. With it both one-sided and doors opening
in the centre can be powered.
The AT18 is supplied with the following motors:
M – 4V /1.8A – Motor for a maximum of 10 kg total door panel weight
M3 – 30V /4.0A – motor for a maximum of 180 kg total door panel weight
The door actuator can be ordered with drive pinions mounted differently (left or right, see drawing
in attachment).
No end switch is needed for the operation of the door actuator.
The door width as well as the positions "OPEN" and "CLOSE" are determined automatically.
A display of the current operating statuses takes place via a 7-segment display (H5000) in the
control unit.
In the attachment all important scale drawings, an assembly suggestion and the identification
numbers for the order of the individual drive components can be found.
