Timers
The 5200A has four daily ten event timers. Timers can be configured to control
various hardware devices. In addition, there is one Feed Smart
tm
feed timer.
Notes:
-
Timer system must be enabled in order to energize the configured timer
relay.
-
If a timer is active (relay energized), the timer is NOT recalculated when the
5200A time and/or date is changed. Once a timer has been turned on, it runs
for it’s configured duration and does not reset it’s run time based on changes
made to 5200A time. Example - Timer 1, event 1 is configured to come on
at 9:00am for 10 minutes. Timer relay energizes at 9:00am. At 9:05am, the
5200A unit time is changed to 10:05am (for daylight savings adjustment). The
timer relay will de-energize after five additional minutes. Unit time will be
10:10am. The event log will reflect the unit time when the event occurred. In
this example, 9:00am for the start time and 10:10am for the end time.
-
If a timer is active (relay energized) and the 5200A is put on service hold, the
relay will not reenergize after service hold expires regardless if timer time has
not expired. There is only one “on” time for all timers. Turn the 5200A off and
then on to reset the timer system. Timer relay will energize for timer system
configured time duration and not for the remainder of time prior to service
hold. Example - timer relay 1 is configured to start at 11:00 am for one hour.
Service hold is enabled and configured for 5 minutes. Timer relay energizes
at 11:00 am. At 11:15 am, the 5200A is put into service hold. Timer relay 1
de-energizes. At 11:20 am, the service hold time expires. The 5200A is power
cycled and timer relay energizes 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 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 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.
Timers 1-4
Menus →Timers→Timer 1-4
Configure up to 40 daily timer events using the 10 events of Daily Timer systems
1-4. Timer events occur on a daily basis until either the start time is cleared, the
timer system is disabled, or the relay is disabled. Timer icon displays at Run Screen
when the timer relay is active. See Icons - page 70
