Figure 5-140: Time of day timer example
The TIME OF DAY 1 ON FlexLogic operand follows the state of the timers. In addition, one-second pulses are generated on the
TIME OF DAY 1 START and TIME OF DAY 1 STOP FlexLogic operands when the timers turn on and off, respectively (see the
following figure). These operands can be combined in FlexLogic with the day and month FlexLogic operands and/or with
FlexElements operating on the DAYOFYEAR, DAYOFMONTH, and SECONDOFDAY FlexAnalog parameters to create virtually
any time and date condition for custom time or season-based control actions. To activate these FlexAnalog parameters,
enable at least one time of day timer.

If the relay is connected to an external clock that follows daylight savings time changes, take care that the changes do not
result in undesired operation.
The following settings are available for each time of day timer element.
TIME OF DAY TIMER 1 START TIME — Used to program the relay clock/calendar value for which the timer turns on.
TIME OF DAY TIMER 1 STOP TIME — Used to program the relay clock/calendar value for which the timer turns off.
TIME OF DAY TIMER 1 EVENTS — If enabled, the TIME OF DAY 1 ON and TIME OF DAY 1 OFF events are logged.
