11.2. Typical system times
Refer to the technical data for the exact values.
Ready delay:
After switch-on, the device carries out a self test. The system is ready for operation only after this time.
Risk time according to EN 60947-5-3:
If an actuator moves outside the actuating range, the safety outputs (OA and
OB) are deactivated at the latest after the risk time.
Difference time:
The safety outputs LA and LB switch with a slight time offset. They have the same signal state no later
than after the discrepancy time.
