6. Function blocks
6.1 Manufacturer function blocks
Operating principle
Each of the 32 year time switches, HY01 through HY32, features four channels that can
each be configured with an ON event and an OFF event in the parameter configuration
for the block. An ON time and an OFF time that are accurate to the day can be selected
for each channel. All channels act jointly on function block output Q1.
Behavior 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 "Real-time clock",
page 586
.
Switching behavior with overlapping channel settings:
If the set ranges overlap, the year time switch activates the contact with
the first detected ON signal irrespective of which channel is supplying this
ON. In the same way, the year time switch switches the contact off with
the first detected OFF, irrespective of whether another channel still sup-
plies the ON signal.
Please note that the time switches can only be configured up to the year
2099.
