Primary/Secondary switch
When using two of either the 0-10V or DALI control
option cards in an ERP48-FT you will need to position
the primary secondary prior to startup. The primary
secondary switch controls which set of relays responds
to which option card.
• When using two different option cards, move the
switch to position 1.
• When using two of the same option cards, move
the switch to position 2.
With the switch in position one, each card will control
the circuits assigned to it, up to 24 circuits.
With the switch in position two, the card connected to
the “option 1” connector will control circuits 1-24.
The card connected to “option 2” connector will
control circuits 25-48.
