Example 5
The power to Pico is removed between 3:00 pm and 5:00 pm. The
relay drops out and remains off, even after the power returns, since
the first switch-off time was at 4:00 pm.
When it is powered on, Pico always updates the switching state on
the basis of all the available switching time settings.
Example 6
The time switch is to operate for 24 hours. Turn-on time at 0:00 on
Monday and turn-off time at 0:00 on Tuesday.
Program a Time Switch
A time switch can be integrated into your circuit in the form of a
contact. Use the parameter display to set the switch-on and switch-off
times.
1. Enter the relay contact for the time switch in the contact field.
The cursor is over the contact number of the time switch.
2. Press Ok to set the switching times.
The parameter set for the first channel is displayed.
3. Set the switching times for the parameter set.
