The Feed Timer can be set to operate for any or all of the days of the week and
includes continuous or timed feeding modes, FCR (feed conversion ratio), and
sensor options.
The following definitions are used in regard to the Feed Smart tm Timer system:
feed cycle - amount of time that all feeds occur in: -
continuous - feedings occur 24 hours/day -
timed - length of time between start and end time -
feed duration - length of time feeder relay is energized; -
feed interval - length of time between feedings. -
Optional Sensor control reduces the amount of food dispensed if DO, pH, or
temperature measurements are “out of range” per user defined configuration. The
FCR (Feed Conversion Ratio) feature automatically computes and increases the
daily amount of food dispensed per FCR configuration.
Notes:
It is important that the 5200A be configured with valid data. The feeder -
system will not operate properly if, for example, the daily weight of food
is greater than can be dispensed in the defined feed cycle.
Disable the feed timer system when changing configuration and/or when -
performing a calibration. Enable the feed timer system after configura-
tion changes and/or a calibration has been done. The feed timer system
recalculates duration and interval times based on the new configuration.

configuration/calibration changes.
Feed Mode
Continuous
Menus →Timers→Feed Smart Timer→Feeder→Feed Mode →Continuous
When the feed timer is configured for continuous feed mode, feedings occur through-
out the day. Feed duration and interval are determined by the daily total weight of
food, number of feedings, and test calibration data. Optional Sensor control and
FCR configuration can also effect feed duration.
Configuring the 5200A
Example of Feed Timer Configuration and Test Calibration Data:
Feed Mode
Continuous (86500 seconds in 24 hours),
feed timer sensor control is disabled
daily weight
500 units daily feedings
100
test calibration
data
10 units per 30
seconds
The 5200A determines feed duration and feed interval for the above feed cycle as follows:
units fed per feeding:
feed time duration for each feeding:
determine total time feed relay will be
energized over 24 hour period:
15 units X 100 feeds = 1500 seconds
determine feed interval:
500 ÷ 100 = 5 units per feed
if 10 units feed in 30 seconds , then 5 units will feed in
15 seconds
30x5
ч 10 = 15
86500 ‐ 1500 = 84900 ч = 100 (number of feeds) = 849
seconds¸ 60 = 14.15 minutes, or 14 minutes and 9
Notes:
Once Continuous feed has been configured, the 5200A determines any -
remaining feeds for the 24 hour period ending at 23:59. In continuous
feed mode, the feed cycle always begins at 00:00 (midnight). Start and
End time fields are not available for Continuous feed mode.
In continuous feed mode, feeding(s) will end after the last completed feed- -
ing that ends prior to 11:59 pm (23:59) of an enabled day when crossing
midnight to a disabled day. Feeding(s) will resume at 12:00 am (00:00)
for the next enabled day.
Timed
Menus →Timers→Feed Smart Timer→Feeder→Feed Mode →Timed
Feedings occur only during the start and end times on “enabled” days of the week.
In timed mode, the 1st feeding occurs at the start time of the feed cycle. The last
feeding completes by the end time. Feed duration and interval are determined by
the daily total weight of food, number of feedings, and test calibration data. Optional
Sensor control and FCR configuration also effect feed duration.
