Example

You wish to control a device connected to the Q2 output of the smart relay. You want

it to be active on the following two clock ranges:

z from Monday to Saturday, from 09:00 to 13:00.

z from Monday to Friday, from 15:00 to 19:00,

For this, the H1 Clock block is used and the following wiring diagram is created:

H1-------------

[Q2

When entering the H1, Clock block, configure the operational ranges A and B as

described in the table below:
