Safety concept
The SIDOOR controller ATE500E disposes of an extensive safety package. The safety
functions fulfill the requirements to EN 62061 for use up to and including SIL 2 (Safety
Integrity Level) as well as 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)
6.3.1
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.
6.3.2
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.
6.3.3
