4.3 Testable single-beam photoelectric safety switches
Testable single-beam photoelectric safety switches can be connected directly to the inputs
of the UE410-MU/UE410-GU/UE410-XU as well as UE410-8DI units.
• For category 2 testable photoelectric safety switches (e.g. L21) the response time of the
respective program applies.
• For category 4 testable photoelectric safety switches (e.g. L41), the response time is
calculated from the response time of the program plus the test period of the program.
• You can find the response times of the programs in chapter 11 “Technical specifica-
tions” on page 96.
The required test signals at X2 for the sensors are generated in program 3.2 of the
UE410-MU/UE410-XU.
The required test signals are generated on X2 in programs 8 and 9 on the UE410-GU.
In switch position 1 of the UE410-8DI the required test signals are generated at outputs
X1 to X8.
Up to 4 testable single-beam photoelectric switches can be cascaded per input. This
means, at the modules UE410-MU/UE410-GU/UE410-XU with one input (I2) each
respectively, at the UE410-8DI with inputs I1 to I8.
A selection of the testable single-beam photoelectric safety switches is available in
section 12.2 “Accessories/spare parts” on page 115.
Ensure protected laying of the connection cables!
If cascades are used, protected separate laying of the connection cables must be ensured.
Connection to UE410-MU/UE410-XU
A testable single-beam photoelectric safety switch/cascade uses the input I2 and test
output X2.
Connection to UE410-GU
A testable single-beam photoelectric safety switch/cascade uses the input I4 and test
output X2.
Connection to UE410-8DI
A testable single-beam photoelectric safety switch/cascade uses the inputs and test
outputs that belong together (for example I1/X1 to I8/X8).
• UE410-MU/UE410-XU:
Input I1 and test output X1 have to be jumpered. Terminal S2 may not be
interconnected.
• UE410-8DI:
The unused inputs have to be jumpered to the corresponding test outputs (for example
the free inputs I2/X2 to I8/X8).
