Total result corresponding to the channel configurations and behavior of
contact Y1 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.
4.13 Master Reset
The master reset function relay enables you to set with one command the
status of the markers and all outputs to “0”. Depending on the operating
mode of this function relay, it is possible to reset the outputs only, or the
markers only, or both. Three function blocks are available.
4.13.0.1 Wiring of the master reset function relay
You integrate a master reset function relay into your circuit in the form of a
contact and coil.
The coils and contacts have the following meanings:
￫
Switching behavior 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!
