Part No. 4801-5338 Rev 01-10 Evolution 4000 53 of 86
8. ALWAYS Back-Up Setting
This is a new setting for relays introduced in the EV4000. It is used if the EV4000 power is lost. In this
case, these stages will turn “ON” (if an Evolution Back-Up System is present). 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 using the breaker box.
