10.6.3.2 Bleed and Feed
The Aegis II has two feed modes based on how long
the bleed valve is open.
The Feed relay in the Bleed and Feed program is
based on a 5 minute time frame. The controller
calculates how long the feed pump should be on
based on 300 seconds X the percentage entered
and starts to feed when the remainder of the 300
second bleed equals this calculated amount.
Example: If the percent is 80, the controller
calculates 80% of 300 or 240 seconds, then starts
the feed when the bleed count down reaches 240
seconds. Both relays will count down to zero. The
feed relay will stop. The bleed will reset to 300
seconds and continue counting down.
When the bleed stops, the feed stops and the
counters are reset.
Prior to configuring these program steps, you need
