9.10 Connecting Stage Jumpers of Evolution
4000
Pictured at below is the 10 stage relay boards consisting of four stage relays per board and the associated stage
jumper for each relay. The stage jumpers are labeled ALWAYS, COOL 1, COOL 2, COOL 3, and HEAT. Location
of the jumper places the stage in one of these five 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:

If the Backup Controller calls for any
Backup Mode, this stage will also be ON.

The
ALWAYS
jumper setting is a new setting for stage
relays introduced in the EV4000. If the Backup
controller calls for any of the four Backup Modes
(COOL 1, COOL 2, COOL 3, or HEAT), each of the
EV4000 stages set to ALWAYS will turn ON when any
Backup Mode is ON. Therefore, this is a good setting
for light, feed, or even fans that you would like to turn on
in case of a failure. Operation of these outputs could be
controlled
