Parameter
Changes in water parameter conditions will affect the amount of food fish eat and thus will affect fish
growth. With the parameter feature enabled, the feed timer system will verify that pH, temperature and
DO values are within user selected ranges. This verification is done immediately prior to starting each
feed cycle duration. If the values are outside these ranges, food weight amount is reduced by a user
selected percentage.
DO/Temp/pH Low
Enter the lower limit of the parameter range where no feed compensation will take place.
DO/Temp/pH High
Enter the high limit of the parameter range where no feed compensation will take place.
DO/Temp/pH Change
Enter the percent reduction in feed weight that will occur for each 1/10 unit of measure the parameter is
out of range. Results from all out of range parameters are added.
Setup Menu
Relay
Assign a relay address to the feeder.
NOTE: Feed calibration cannot be performed if the Relay is disabled.
Units
Select lb (pound), g (gram), kg (kilogram), or oz (ounce) as the unit of weight the Feed Timer System
uses for the calibration/test sample amount and to the total daily feed amount.
NOTE: If the units are changed, the feeder must be recalibrated.
Test
Calibrating (Testing) the feeder is essential for proper operation of the Feed Timer System. Calibration
will determine the rate at which food is dispensed from a feeder. This information is used to determine
feed cycle duration(s).
NOTE: A relay must be assigned in order to enter the Calibrate Feeder menu.
Calibrate Feeder
Enter the amount of time the feeder relay will be energized for testing; 001–500 seconds. The relay will
energize after the last digit is entered. After the timer counts down to zero, the feed relay deenergizes and
the Measured Weight screen is displayed.
