Belt break monitoring
Description of function
The function detects a torn belt. The detection is active in normal mode and initial mode.
A torn belt is detected when the door movement exceeds the defined distance* (in the
opening or closing direction).
* The distance is defined as follows:
Mode
Controller
Distance
Initial operation
SIDOOR ATD4xxW
Max. door width +
50 cm (p1201)
Normal operation SIDOOR ATD4xxW
Learnt door width +
50 cm (p1201)
Parameter assignment
Belt break detection is suppressed if parameter p1201 is set to "0". In this case, there is no
fault or fault reaction on the part of the controller.
The status code "t" signals a torn belt. The controller changes to the status "S6: Z_Störung"
(see Figure 4-4 Sequential control state graph (Page 149)).
If the parameter set of the controller is invalid, the maximum possible door width of 5 m is
used as the door width.
See Table 4-35 Calibration and function parameters (Page 179).
