Connecting Stage Jumpers of Evolution
3000 & 3001
Pictured at below is a stage relay board consisting of four stage relays and the associated stage jumper for
each relay. The stage jumpers are labeled COOL 1, COOL 2, COOL 3, and HEAT. Location of the jumper
places the stage in one of these four modes, or if the jumper is NOT inserted, the stage is NOT placed on
Back-up. The jumpers should be placed based on the operation of stage equipment and should be the same
as assigned in the Master Controller.
Jumpers are placed according to the following table:
