Function test when safety channels are connected in series
Before commissioning and after each change, check that the safety function is guaranteed
when the gates are opened. To do this, open each gate individually and check the status at
the inputs on the evaluation device:
} Close all the gates.
There must be high signals at the inputs on the evaluation device (e.g. S11, S21 or I1,
I2).
} Open one gate; the other gates remain closed.
There must be low signals at the inputs on the evaluation device (e.g. S11, S21 or I1, I2).
} Close the gate again.
High signals must return at the inputs on the evaluation device (e.g. S11, S21 or I1, I2).
} Repeat the test for each gate.
} If the input signals do not react as described above, check and rectify the wiring and carry
out the test again.
