Notes:

- If a timed feed cycle includes feed times that cross midnight, the feed

cycle ends prior to 11:59 pm (23:59) of the enabled day when crossing

midnight to a disabled day. Feeding(s) will resume on next enabled day.

Example - if Tues through Sat are enabled days and the start time is con-

figured for 10:00 pm (23:00) and the end time is configured for 01:00.

On a Saturday, the feed cycle would start at 10:00 pm (23:00). The last

feed occurs by 11:59 pm (23:59) on Saturday since Sunday is a disabled

day. The next feed occurs at 12:00 am (0:00) on Tuesday. This feed cycle

would end at 01:00 on Tuesday. No feeding occurs Monday, because

Monday is a disabled day.

- The Feed timer will not operate properly if the start date is set prior to

January 1, 2007.

Daily Weight

Menus →Timers→Feed Smart 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 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 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 5200A 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

5200A time crosses midnight. See below.

Biomass

Menus →Timers→Feed Smart 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 5200A will not calculate the initial amount). Example—if

the biomass is 1000 and the feed % biomass is 3%, then the initial daily feed weight

amount is 30. On each following day, the 5200A 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.

Configuring an invalid initial daily weight will result in incorrect biomass

and daily weight calculations when the 5200A 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.
