Inserting Multiple Gates or Events
To insert multiple gates or events:
1. In the FTA Diagram, select the Mech Fault OR gate.
2. Select > . The Insert Event window opens.
The default input type is Basic Event.
3. Click OK to insert a basic event.
The mouse cursor changes shape to show the type of gate or event you are inserting. In this case, it is the circle icon, which indicates a basic event. Also shown is a plug icon.
◦ When a red warning symbol appears over the plug icon, you cannot insert the event in the current location.
◦ When no warning symbol appears over the plug icon, you can insert the event in the current location.
4. Move the cursor so that the circle shape is over the gate labeled Mech Fault. Because you can insert the basic event in this location, the warning symbol does not appear over the plug.
5. Click to insert the basic event. The cursor retains the shape of the basic event so you can continue to insert basic events.
6. Click to insert one more basic event under the Mech Fault OR gate.
7. Move the mouse over to the Elec/SW Fault OR gate and insert a single basic event.
8. Right-click to exit the insertion mode. The mouse cursor returns to its normal shape.
