Types CL-LSR.C... /CL-LST.C... and CL-LMR.C.../CL-LMT.C...
are provided with a real-time clock. The time switches can
only be used properly in these devices.

The procedure for setting the time is described under
section "Setting date and time" on Page 205.
The logic relay offers eight 7-day time switches
up to 32 switch times.
Each time switch has four channels which you can use to set
four on and off times. The channels are set via the parameter
display.
The timer has a back-up battery. This means that it will
continue to run in the event of a power failure, although the
time switch relays will not switch. When the logic relay is in
a de-energized state, the timer contacts remain open.
Information on the battery back-up time are provided on
Page 256.
h Compatibility with AC010
If you wish to load an existing AC010 circuit diagram, the
existing 7-day time switch functions are retained. The 7-
day time switches in the CL-LSR/CL-LST and CL-LMR/
CL-LMT operate in the same way as in the AC010.
A 7-day time switch can be integrated into your circuit in the
form of a contact.
