Programming IDEC SmartRelay70 IDEC SmartRelay Manual3.6.7 Second circuit programUp to this point, you have successfully created your first cir-cuit, and assigned it a name and, if desired, a password. Inthis section we are going to show you how to modify existingcircuit programs and how to use the special functions.Using this second circuit program, we are going to show youhow to:• Add a block to an existing circuit program.• Select a block for a special function.• Assign parameters.Modifying circuitsWe 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 secondcircuit program:In IDEC SmartRelay, this is the circuit program layout:You can see the OR block and the output relay Q1 we havealready used in the first circuit program. The only differenceis the new off-delay block.L1NS1 S2 K1K1 E1You already know the first part ofthe circuit. S1 and S2 switch a relay,which is to be used to switch on theload E1, and to switch off the loadwith a delay of 12 minutes.≥ 1Q1I1I2x xParThis is thenew blockngineering, Inc. ● 230 Ryan Way, South San Francisco, CA 94080-6370 ● General Inquiries: (800) 670-4183 ● www.ste
