•
Maximum 2 pairs per input can be cascaded with test pulse width =
4ms (standard element in the configuration software)
•
Maximum 5 pairs per input can be cascaded with test pulse width =
12ms (user-defined element required in configuration software)
L21:
•
Maximum 10 pairs per input can be cascaded with test pulse width
= 4ms (standard element in the configuration software)
•
Maximum 25 pairs per input can be cascaded with test pulse width
= 8ms (user-defined element required in configuration software)
L27/L28:
•
Maximum 7 pairs per input can be cascaded with test pulse width =
4ms (standard element in the configuration software)
•
Maximum 18 pairs per input can be cascaded with test pulse width
= 12ms (user-defined element required in configuration software)

5.4.3.2 Testable type 4 safety single-beam sensors
Table 74: Connection of testable type 4 safety single-beam sensors
Electrical connection: example with FX3-XTIO
L41 Test input TI (sender) at X1
Output Q (receiver) at I1
WARNING
Impairment of fault detection due to cross-circuit
The dangerous state may not be stopped or not be stopped in a timely manner in the
event of non-compliance.
►
Prevent cross-circuits between the connection from the test output of the Flexi
Soft module to the test input of the sender and the connection from the output of
the receiver to the safe input of the Flexi Soft module with protected or separate
cabling.
