Figure 8 - Connecting a Single-channel Mechanical Contact
Figure 9 - Connecting Mechanical Contacts of a Dual-channel E-stop
When only one dual-channel E-stop button is used, the maximum safety
performance rating is Cat 4 PLe and SIL CL3.
Figure 10 - Connecting Mechanical Contacts of a TLS3-GD2
Since the TLS3-GD2 has multiple contacts in series, the maximum safety
performance rating is Cat 3 PLd and SIL CL2.
Regardless of how these are wired, performance remains the same. The GLT
successfully recognizes when one or both channels open, and the GLT detects
cross channel faults and single channel faults to +24V and to 24V common.
TIP
Pulse test output S11 can be connected to either S12 or S22. Pulse test output
S21 can be connected to either S12 or S22.
