Note:
This phenomenon follows the principle that latter commands surpass for -
mer ones.
6. When the week system is selected, if ON is set at 8:00 and Off is set at 9:00
from Monday to Thursday (MO~TH), then FR, SR and SU will maintain their
former status ,that’s, the original ON status will keep ON while the original OFF
status will keep OFF.
7. During your programming by using the LCD panel, if the week system is se-
lected, D will be ignored by the FAB when you set D, T1 and T2. This means that
only T1 and T2 are needed to be set. But if the day system is selected, D is a must.
D is the setting of date, T1 is the setting of ON time, and T2 is the setting of OFF
time.
8. Clock hold circuit
For a FAB, when there is a power failure, the internal clock will continue run-
ning. The time that the FAB can maintain the internal clock to run depends on
the temperature. When the temperature of the FAB is 25
℃
, the clock is able to
continue its normal operation for more than 100 hours after the power is cut off.
9. Conflicts between time intervals
When time intervals are used to set the ON/OFF time of a clock, the clock switch
will make the output ON at the ON time unless it has already been ON status,
and make the output OFF at the OFF time unless it has already been OFF status.
10.Accuracy of a RTC (Real Time Clock)
The accuracy of a RTC can reach 1s. Only one FB (Function Block) is needed
to do the work with duration of less than one minute. This function is applicable
to the controls related to time, e.g. ringing bell for classes in school and work in
factories, timed start-up and shutdown of machines, etc.
