Signals
Signal
Meaning
1 (high)
Pressure-sensitive edge is not interrupted and is fault-free.
0 (low)
Pressure-sensitive edge is interrupted or defective*.
* The response of SIDOOR ATD4xxW controllers also depends on the particular system mode. See
the table below.
Table 3- 13 Response of SIDOOR ATD4xxW controllers to an active pressure-sensitive edge signal
Mode
Response
Learn run mode
Learn run is canceled and the drive is deenergized.
Initial mode
The system is stopped and then deenergized via a ramp down in con-
junction with the active drive order.
Normal mode
The system reverses by 20 cm in conjunction with the active drive order.
The drive is stopped and then deenergized if an obstruction is detected
during reversing.
In positioning mode, the drive is stopped and deenergized via a ramp
down.
Special mode
No response
3.4.2
Security policy
The SIDOOR controllers ATD4xxW dispose of an extensive safety package. The safety
functions fulfill the requirements according to DIN EN ISO 13849-1 Cat 2 PL d (Performance
Level).
The scope of the safety functions includes:
●
Safe force output
●
Safe speed observance (energy limiting)
●
Safe input signals
3.4.2.1
Safe force output
The maximum forces configured by the user must always be observed for safety reasons.
The safe force output of the SIDOOR system ensures that the torque output by the motor
does not increase in case of an error. Unintentional increases in the torque are recognized
and result in a defined error response.
3.4.2.2
Safe speed observance (energy limiting)
The speeds configured by the user must always be observed for safety reasons. The safe
speed observance of the SIDOOR system ensures that the energy of the door does not
increase in case of an error. Unintentional increases in speed are recognized and result in a
defined error response.
