Operating Instructions

Non-Contact Safety Switch CES-A-C5H-EX

24

(Translation of the original operating instructions) 2110182-09-12/18

13.1.2. Typical system times

Please refer to the technical data for the exact values.

Ready delay

: After switching on, the device carries out a self-test. The system is ready for operation only after this time.

Switch-on time of safety outputs

: The max. reaction time t

on

 is the time from the moment when the actuator is in the 

operating distance to the moment when the safety outputs switch on. This time corresponds to the risk time.

Risk time according to EN 60947-5-3

: If an actuator moves outside the operating distance, the safety outputs (LA and 

LB) are switched off no later than after the risk time.

Discrepancy 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.
