Version No.: B.2
NOTE
It is up to the user to verify that multiple devices are not allocated to
the same input.
VIU MCFs, such as those shown Figure 4-4 below, allow users to specifically define which input
on each particular box to use. Using the example provided in Figure 4-3, this interlocking
consists of two signals (Sig01 and Sig02) and one switch (Sw01) (see Figure 4-4).
Figure 4-4 Interlocking Equipment: Signal 1, Signal 2, and Signal 3
Sig01 Head A will use Box 1, Input #1, which then automatically programs Input #1 as green, #2
as yellow and #3 as red, with Head B using Box 1, Input #4 which then programs Input #4 as
red, and Head C is programmed as not used (see Figure 4-5).
