Parameter settings of the year time switch HY01:
ON/OFF
: First/last switch-on year.
ON/OFF
: First/last switch-off year.
Example 10: Overlapping time ranges (2-channel)
This example shows how to configure the parameters for continuous
overlapping time ranges on adjacent channels.
The HY01 year time switch, channel C, switches on at 00:00 on the third of
months 5, 6, 7, 8, 9, 10 and remains switched on until 00:00 on the 26th of
these months.
The HY01 year time switch, channel D, switches on at 00:00 on the second
of months 6, 7, 8, 9, 10, 11, 12 and remains switched on until 00:00 on the
18th of these months.
Total result corresponding to the channel configurations and behavior of
contact Q1 in this example:
The time switch switches on at 00:00 on 3 May and stays on until 00:00 on
26 May. In June, July, August, September, October, the time switch will
switch on at 00:00 on day 2 of the month and switch off at 00:00 on day 18.
In November and December, the time switch will switch on at 00:00 on the
second of the month and switch off until 00:00 on the 18th. The following
note explains this switching behavior.

￫
Switching behaviour with overlapping channel settings:
If parameterized ranges overlap, the year time switch switches
the contact on with the first detected ON, irrespective of which
channel supplies this ON signal. In the same way, the year time
switch switches the contact off with the first detected OFF,
irrespective of whether another channel still supplies the ON
signal!
