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 will show you how to modify existing circuit
programs and how to use the special functions.
Using this second circuit program, we will 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.
First of all take a look at the circuit diagram for the second
circuit program:
L1
N
S1
S2
K1
K1
E1
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.
This is the circuit program layout in IDEC SmartRelay:

This is the
new block
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.
