3. Verifying the safety logic circuit.
– When either the pendant Emergency Stop, safety fence, or the
external Emergency Stop is input, General Purpose Safety Output
Signal 1 becomes ON.
11.3.9.3 Example3 (Pulse)
The one-second one-shot output signal is created by the safety logic
circuit. In the following example, the GP safety output signal (#1 GSOUT1)
is ON for one second.
1. Create the following Safety Logic Circuit.
2. The timing chart is as shown below:
To use “Detect OFF → ON” or “Detect ON → OFF” for
Input relay, Output relay should be “Pulse”. Also, to use
“Pulse” for Output relay, one of the input relay should be
“Detect OFF
→ ON” or “Detect ON → OFF”.
Number of Input relay should be 2 or less.
