3.7.2

Reset pushbutton requirements

The reset pushbutton must be installed outside of the hazardous area. From the posi‐
tion of the pushbutton, there must be a complete view of the hazardous area.

The pushbutton must be designed according to the following standard:

EN 60204

The reset signal must be triggered only if the reset pushbutton has be released from its
activated position again (in accordance with ISO 13849-1).

For this reason, the signal processing function must detect the falling edge of the signal
from the reset pushbutton. A reset is permitted only if all safety functions and protec‐
tive devices are functional.

3.7.3

Robot controller requirements

Safety functions

The robot must have the following safety functions and safety inputs suitable for these
in accordance with category 3 (ISO 10218-1, 5.4.2) with Performance Level d or SIL 2
(IEC 62061):

Emergency stop (ISO 10218-1, 5.5.2)

Protective stop (ISO 10218-1, 5.5.3)

Robot controller functions

Yes

Yes

1)

SS1 (corresponding stop category 1) or SS2 (corresponding stop category 2) can be used. When SS1 is
used, the signal for restart must come from a superior control.

Reset and restart requirements

After emergency stop or switching on:

Manual reset is monitored by the safety system. If resetting is possible and the
reset pushbutton is pressed, the emergency stop output switches to the ON state
(HIGH) so that the robot can be started.

Resetting the robot is only possible if the user has executed a restart. Restart is
manual restart. Implementing manual restart is the responsibility of the manufac‐
turer.

The robot controller must prevent restart after a change in the operating mode
(e.g.from automated mode to manual mode for teach-in). A restart is only possible
after a valid reset.

After protective stop (with manual reset):

Depending on the robot type and the requirements of the application, a manual
restart may be necessary after performing the risk assessment. In this case, a
manual reset must be implemented on the safety controller. Resetting the robot is
only possible if the user has executed a restart. Implementation is the responsibil‐
ity of the manufacturer.
