Interlock-check formula
Figure 4.7-2 shows a device (Q0) in the feeder bay, if a control action to operate (Q0) is required,
an interlock-check will be necessary. To control the device (Q0), the interlock-check must verify
the status of several devices in the busbar and the bay.

Figure 4.7-2 Example of device status and Interlock-check
In accordance with the arrangement of the devices shown in Figure 4.7-2, interlock-check
formulae can be configured from equations (4.7-1) to (4.7-9). The status of respective devices,
(stVal) and interlock operators (“•” and “+”) are placed on the right-hand side of the equations;
and the interlock condition (e.g. Q0(Closing)) is placed on the left-hand side of the equations.
The interlock operators are also shown in Table 4.7-2.
