5.16 HW, weekly timer
An easy800 device is provided with a real-time clock, which you can use in
the circuit diagram as a weekly and year time switch.
easy800 device allows for the use of up to 32 function blocks of type weekly
timer.
For each weekly timer four switch channels A, B, C and D are available.
You can choose an on and off switching time for every channel. These
channels of the weekly timer all act jointly on the contact Q1 that you include
in the circuit diagram. The channels are set via the parameter display or
easySoft.
Behaviour in the event of a power failure
The time and date are backed up in the event of a power supply failure and
continue to run. This means that it will continue to run in the event of a
power failure, although the time switch relays will not switch. The contacts
are kept open when de-energized. Information on the battery back-up time
are provided on
section 12.3.4, “Central processing unit, real-time clock/
timing relay/memory”, page 348.
