16.1.1. Typical system times
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.
Turn-on time of safety outputs:
The max. reaction time t
on
is the time from the moment when the guard is locked to the moment when the safety outputs
switch on.
Risk time according to EN 60947-5-3:
The risk time is the maximum time until at least one of the safety outputs FO1A or FO1B switches off safely when the actuator
is removed from the actuating range. This also applies if an internal or external fault occurs at this moment.
The following applies to active guard lock monitoring: If guard locking is no longer effective, the safety outputs
FO1A and FO1B are switched off after the risk time at the latest.
The following applies to inactive guard lock monitoring: If an actuator moves outside the actuating range,
the safety outputs FO1A and FO1B are switched off after the risk time at the latest.
If several devices are operated in a series connection, the risk time of the overall device chain will increase with each device
added. Use the following calculation formula:
t

+(nxt

)
t
r
= Total risk time
t
r,e
= Risk time for single device (see technical data)
t
l
= Risk time extension per device
n = Number of additional devices (total number -1)
Discrepancy time:
The safety outputs FO1A and FO1B switch with a slight delay in relation to each other. They have the same signal state no
later than after the discrepancy time.
Test pulses at the safety outputs:
The device generates its own test pulses on the safety outputs FO1A and FO1B. A downstream control system must tolerate
these test pulses.
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 test pulses are required, contact our support organization.
The test pulses are output only if the safety outputs are switched on.
