Rievtech xLogic ELC Series User Manual page 105

When you select the every month check box, the yearly clock switches on or off at a certain day of every
month.
Backup of the real-time clock
The internal real-time clock of xLogic is buffered against power failure. The buffering time is influenced
by the ambient temperature, and is typically 100 hours at an ambient temperature of 25°C.
Special characteristics to note when configuring
A click on the dialog box enables direct keyboard input of the month and day values. The values entered
may not exceed the logical maximum of the relevant input boxes; otherwise xLogicsoft returns an error
message.
The calendar icon offers you an Rievtech way of setting the date. It opens a window where you can set
the days and months by clicking the relevant buttons.
Sample configuration
The output of an xLogic is to be set annually on March 1, reset on April 4, set again on July 7,
and reset again on November 19. You need to configure two yearly timers with corresponding on-times.
Then logically link the outputs by means of an OR block.
