Second circuit program
Up to this point, you have successfully created your first cir-
cuit, and assigned it a name and, if desired, a password. In
this section we are going to show you how to modify existing
circuit programs and how to use the special functions.
Using this second circuit program, we are going to show you
how to:
•
Add a block to an existing circuit program.
•
Select a block for a special function.
•
Assign parameters.
Modifying circuits
We shall use the first circuit program as a basis for the sec-
ond, with some slight modifications.
Let us take a first look at the circuit diagram for the second
circuit program:
In IDEC SmartRelay, this is the circuit program layout:
You can see the OR block and the output relay Q1 we have
already used in the first circuit program. The only difference
is the new off-delay block.

You already know the first part of
the circuit. S1 and S2 switch a relay,
which is to be used to switch on the
load E1, and to switch off the load
with a delay of 12 minutes.
