Typical system times
Ready delay: After switching on, the unit carries out a self-test for 8 s. The system
is ready for operation only after this time.
Switch-on time of safety outputs: The max. reaction time from the moment
when the safety guard is locked to the moment when the safety outputs switch
on T
on
is 400 ms.
Risk time according to EN 60947-5-3: If an actuator moves outside the oper-
ating distance, the safety outputs OA and OB on the corresponding safety switch
are deactivated after a maximum of 500 ms.
Difference time: The safety outputs OA and OB switch with a slight time offset.
They have the same signal state at the latest after a difference time of 10 ms.
Clock pulses at the safety outputs: The device generates its own clock signal
on the output lines OA/OB. A downstream control system must tolerate these
pulses, which may have a length of up to 1 ms.
This can usually be set up in the control systems by parameter assignment. If
parameter assignment is not possible for your control system or if shorter clock
pulses are required, please contact our support organization.
