9 Electrical adjustment with the minimal editor
The minimal editor is a tool for changing the parameters of an AT40 controller if the terminal module, Service Tool or Sidoor
User Software are not available. In this case, the learn run button (S401) and the two service buttons (S402, S403) are
assigned second functions. The LED display (H401) is used to visualize messages.
Activating the minimal editor requires a specific button pressing procedure, which can only be done after a mains reset. The
detailed operation is as follows:
1. The OPEN and CLOSE buttons must be pressed simultaneously when the program starts (supply voltage switched on).
An 8 appears in the display for approx. 5 seconds as confirmation.
2. As soon as the display stops, the user must release both buttons (time window approx. 3 seconds), and not touch them
until the time window has ended.
3. A 'C' is now shown in the display to confirm successful activation of the minimal editor.
The minimal editor allows two settings: the selection of a fixed profile or the joint setting of the closing forces. A value is set
with the service buttons (S402, S403). The data are accepted by pressing the learn run button (S401) for more than two
seconds. Successful saving is confirmed by a dot in the LED display. Briefly pressing the learn run button merely switches to
the other parameters without changing the respective value.
The display of a value alternates between a numerical value and an identifying code letter ('A' for forces in the closing
direction or 'C' for the selection of a profile). Values between 1 and 6 can be used to set the profile (1 for the default profile
and 6 for profile no. 6). The closing forces are set in the form of a counterweight, whereby 1 kg is simply taken as 10 N. The
input can range from 0 to 8, where 0 stands for "no counterweight" and 8 for an "8 kg counterweight". The input of the
counterweight changes the closing force, as it is subtracted from the maximum value of 150 N. The setting 8 therefore
reduces the closing force to 70 N (150 N – 80 N = 70 N). The minimal editor is exited by switching the power supply voltage
off and on again.
WARNING
So that the closing speed and nudge speed can be limited as a function of the door weight, it is essential that a new learn
run is made with the heaviest door in the system after taking over another profile. (Click the S401 button to start the run.)
WARNING
Selecting a profile overwrites the input of the counterweight. Therefore the value for the counterweight (parameter 'A') must
be set last.
