. Connect the light barrier to X6 (see illustration or lid imprint).
Insofar as the light barrier input is not used, X6 must be wired to X4 according to the lines on the
connection layout.
3. Plug in clip plugs X6 and X4.
CAREFUL
The control is operative after the next switch-on. At a presented control signal the door moves into the
specified direction.
4. Switch control on (plug in mains current plug, or plug X3).
The four LEDs next to the plug-in connector X3 indicate which control signal is active at the
time. Thereby the LED for the light barrier should glow continuously, if there is no obstacle in the
movement area of the door.
5. At a presented control signal "CLOSE" the door closes with the initial speed in the "CLOSE" position.
At a presented control signal "OPEN" the door opens with the initial speed in the "OPEN" position.
16. If the control has recognized the final door positions "OPEN" and "CLOSE", the subsequent opening
and closing movements are performed in the normal speed.
17. For special applications the movement values can be specifically adapted to the door. However, for
that the terminal module (option), the user terminal HT8 (HT5) must be connected to a PC, or
be connected via a USB adapter (option), on which the operating program AT Frontend has been
started. The operation is described in attachment of the operating instructions.
Simple settings can also be executed with the three buttons and the 7-segment display of the basic
equipment (see section 5).
WARNING
The service staff should test the acceptable energies and forces after the putting into operation of the
elevator door on the heaviest door in the complete system (elevator) and to adjust it to the critical
limits in case of an exceeding of the values.
5 Electrical configuration with the "MinimalEditor"
The simple adjustability of the profile and of the closing forces is indicated as minimal editor via the
three internal buttons with the aid of the 7-segment display. For this purpose no terminal module,
user terminal or AT Frontend PC is necessary. The closing force is set in the form of a counterweight,
whereby simplified 1kg to 10N is calculated. This value must be deducted from the maximum value
50N.
Configuration:
. Start of the minimal editor: press service button – "OPEN" and – "CLOSE" (S500 and S500)
immediately at the same time as supplying the mains current and keep pushed in.
The LED display (H5000) displays an "8" for approximately 5 seconds.
. Let go of both buttons after switch-off of the LED display "8".
3. After approximately 3s a "C" (movement profile) and a numerical value is displayed alternatively.
The displayed numerical value represents the profile number deposited in the AT18.
4. The desired profile can be selected with the service buttons – "OPEN" and – "CLOSE" (S500, or
S500).
5. The set value is saved by a long pressing of (>s) of the parameter button (S5000). A dot appears
