The time of day timer function provides the ability to program control actions based on real time. There are five identical
time of day timers, each with an independent start and stop time setting. Each timer is on when the C70 real-time clock/cal-
endar value is later than its programmed start time, and earlier than its programmed stop time. The timers wrap around
24 h as illustrated below.
The FlexLogic operand follows the state of the timers. In addition, one-second pulses are generated on

the and

the figure below). These operands can be combined in FlexLogic with the day and month FlexLogic operands and/or with
FlexElements operating on the
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 time changes, care should be taken 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: This setting is used to program the relay clock/calendar value for which the timer turns
on.
• TIME OF DAY TIMER 1 STOP: This setting is used to program the relay clock/calendar value for which the timer turns
off.
• TIME OF DAY TIMER 1 EVENTS: If enabled, the
