Feed Smart Tm Timers 1-4 - YSI MultiDO 5400 User Manual

Timer relay will energize for entire configured duration time and not for the
remainder of time prior to being placed in downloader. There is only one "on"
time for all timers. Example - timer relay 1 is configured to start at 11:00 am
for one hour. The timer relay energizes at 11:00 am. At 11:15 am the 5X00 is
put into downloader. Timer 1 relay de-energizes. Timer 1 relay re-energizes
30 seconds after a power cycle following the downloader (at approximately
11:24 am). The timer relay de-energizes at 12:24 pm and not at 12:00 pm
which would have been the original off time if the unit had not been placed
in downloader.
- If power fails when a timer is energized and the power is restored when the
timer system is still active, the timer relay will energize for the timer dura-
tion and not for the remaining original timer cycle. Example - timer one is
configured to start at 10:40 for one hour. The power fails at 11:30. Power is
restored at 11:35. The timer will energize for one hour, not the remaining 5
minutes of the original timer cycle.
- When the timer relay is energized after the timer duration is changed, the timer
relay de-energizes and reenergizes for the newly configured duration and not
for the remaining original timer duration. Example - timer one is configured
to turn on at 8:30 am for 10 minute duration. Timer one relay energizes at
8:30 am. At 8:35 am, timer one duration is changed to 20 minute. Timer one
relay de-energizes at 8:35 am and re-energizes for the newly configured 20
minute duration.
- When the timer start time and duration are reconfigured and fall within the
current 5X00 unit time, the relay energizes for the entire duration. Example
- The 5X00 unit time is 8:30 am. Timer one is configured to turn on at 8:00
am for one hour. The timer relay will energize at exit to run screen and will
remain energized for one hour. The 5X00 does not use the system clock to
calculate duration in this case. The following day, the relay will energize at
8:00 am, and de-energize at 9:00 am.
- There is a 30 second delay at power up before timers become active.
- Timer relay off times drift by < .2%. when duration is longer than 5 minutes.
The drift increases the relay 'on' time.

The 5X00 has four feed timers. In order to configure feed timer(s) correctly, it is
important to understand how the 5X00 functions based on the feed timer configu-
ration. The Feed Smart Timer system must be calibrated prior to use. For proper
tm
operation, the Feed Timer System requires the user to enter the total amount of
food to be dispensed, number of feedings to dispense the food, and a defined time
period within which the feedings will occur. The Feed Timer can be configured to
operate for any or all days of the week and includes continuous or timed feeding

modes, FCR (feed conversion ratio), and sensor options.
when any Feed Smart tm timer relay is energized.
The following definitions are used in regard to the Feed Smart
- feed cycle - amount of time that all feeds occur in:
- continuous - feedings occur over 24 hour per day period;
- timed - feedings occur only between configured start and end times;
- 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 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 5X00 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 configuration
changes and/or calibration has been done. The feed timer system recalculates
duration and interval times based on the new configuration. Press
after disabling the feed timer system and before making configuration/cali-
bration changes.
