Primary/Secondary Switch (48-Position Panel Only)
When using a combination of two option cards in an Echo Relay
Panel, you will need to position the Primary/Secondary switch prior
to startup. The Primary/Secondary switch controls which set of
relays responds to each option card.
Option Card 1 will always control positions 1–24. If the Primary/
Secondary switch is in the “Primary” position, Option Card 2 will
also control positions 1–24. If the Primary/Secondary switch is in the
“Secondary” position, Option Card 2 will control positions 25–48.
See the examples in the tables below.
