5.4 Connection of devices
This section describes connecting safe and non-safe sensors, actuators and switching
e
lements on the Flexi Soft system and provides mounting information on selected
functions.
Sensors
WARNING
Ine
ffectiveness of the protective device due to unrecognized switching signals between
the safety sensors
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Select the minimum switch-off time of the connected sensors to be greater than
the logic execution time of the Flexi Soft system. Observe the minimum switch-off
time indicated in the technical data of the sensors.
►
Observe the safety notes and description of operation of the connected sensors.
In case of doubt, contact the device manufacturer.
►
Observe the instructions on commissioning and daily thorough checking in the
operating instructions of the connected sensors.
Single-channel inputs
WARNING
Ine
ffectiveness of the protective device due to unexpected pulses or delayed falling
signal edges at single-channel inputs
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
The target safety-related level may not be achieved in the event of non-compliance.
►
Protect single-channel inputs against short-circuits and cross-circuits.
►
Make sure the signal line is laid with protection (to prevent a cross-circuit with
other signal lines).
►
No short-circuit detection, i.e., no referencing to test outputs.
