Configuring the 5X00
- The Feed timer will not operate properly if the start date is set prior to Janu-
ary 1, 2007.
Daily Weight
Menus →Timers→Feed Smart tm Timer→Feeder→Daily Weight
The daily feed amount is the total weight of food that will be dispensed over the
feeding cycle. The value is user selectable from 1 to 100000. The Feed Timer system
divides the total daily feed amount by the number of daily feedings and uses the
calibration/test data to determine feed duration and interval times.
Daily Feedings
Menus →Timers→Feed Smart tm Timer→Feeder→Daily Feedings
Configure the number of feedings to occur in feed cycle. The value is user select-
able 1–255.
FCR
Menus →Timers→Feed Smart tm Timer→Feeder→FCR
The optional FCR (feed conversion ratio) feature automatically increases the amount
of food dispensed over a feed cycle. The increase in the amount of food is based on
the user configured increase in biomass over a 24 hour period. Biomass and daily
(feed) weight amounts are adjusted by the 5X00 prior to the 1st feed “on” time of a
scheduled feed cycle occurring after midnight.
Notes:
- With FCR enabled and properly configured an event occurs when the 5X00
time crosses midnight. See below.
Biomass
Menus →Timers→Feed Smart tm Timer→Feeder→FCR→Biomass
Enter the total weight of livestock being fed at the time FCR is enabled. The value
is user selectable 1 to 100000.
Feed % (of) Biomass
Menus →Timers→Feed Smart Timer→Feeder→FCR→Feed % Biomass
Enter the percentage of the total livestock weight (biomass) that will be used to
determine the daily feed weight. The value is user selectable 0.0–99.9%.
Daily (Feed) Weight
Menus →Timers→Feed Smart Timer→Feeder→FCR→Daily Weight
Configure the initial daily feed weight by multiplying the biomass amount by the
Feed % Biomass percentage (the 5X00 will not calculate the initial amount). Ex-
ample—if the biomass is 1000 and the feed % biomass is 3%, the initial daily feed
weight amount is 30. On each following day, the 5X00 will use the biomass value
along with the feed % biomass to calculate the new daily feed weight amount.
Note:
- The initial daily weight value must be calculated as described above. Config-
uring an invalid initial daily weight will result in incorrect biomass and daily
weight calculations when the 5X00 crosses midnight.
FCR Factor
Menus →Timers→Feed Smart Timer→Feeder→FCR→FCR Factor
Enter the ratio of the amount of food required versus the corresponding increase
in fish weight (biomass). This value is used to automatically increase the biomass
amount—as shown in the example below.
