after 30 seconds. The timer relay de-energizes at 12:20 pm and not at
12:00 pm which would have been the original off time if the unit had not
been placed in service hold.
Energized timer relays de-energize during a firmware update. The relay -
will reenergize after power cycle following a firmware update if the timer
system is still active. Timer relay will energize for the entire configured
duration time and not for the remainder of time prior to being placed in
downloader mode. There is only one “on” time for all timers. Example -
timer relay 1 is configured to start at 11:00 am for one hour. Timer relay
energizes at 11:00 am. At 11:15 am, the 5200A is put into downloader
mode. Timer 1 relay de-energizes. Timer 1 relay re-energizes 30 seconds
after power cycle following the firmware update (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
duration 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 5200A unit time, the relay energizes for the entire duration.
Example - The 5200A 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 5200A 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.

relay turns on at 10:15, relay turns off at 10:25, relay turns on at 10:25,
relay turns off at 10:50.
Configure “0” as the duration time to disable any of the 10 timer -
events.

Feed Smart tm Timer
Menus →Timers→Feed Smart tm Timer
The 5200A has one feed timer. In order to configure feed timer correctly, it is impor-
tant to understand how the 5200A operates based on the feed timer configuration.
The Feed Smart tm Timer system must be calibrated prior to use. For proper opera-
tion, 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.
