a.If 1001 = ON And 1004 = ON And 0004 = ON Then 1005 = ON.
b.If 0000 = ON And 1005 = ON And 0003 = OFF Then 1006 = ON ( Hold ON ).
c.If 0005 = ON And 0006 = OFF And 1006 = ON And 1011 = OFF Then 1007 = ON ( Hold ON ).
d.If 0006 = ON And 0005 = OFF And 1006 = ON And 1010 = OFF Then 1008 = ON ( Hold ON ) And T001 Activated .
e.If 1008 = ON And T001 = ON And 1006 = ON And 1011 = OFF Then 1009 = ON ( Hold ON ) And T002 Activated.
f.If T001 = ON Then SET 1010 = ON ( Hold ON ).
g.If T002 = ON Then SET 1011 = ON ( Hold ON ).
h.If 1009 = ON And T002 = ON And 1006 = ON And 1010 = ON Or 1011 = ON Then 1012 = ON ( Hold ON ).
i.If 1012 = ON And 0005 = ON Or 1006 = OFF Then RES 1010 = ON ( 1010 = OFF ) And RES 1011 = ON ( 1011 = OFF ).
See Picture to Set Value Timer for :
1. Stability Current from Power to Heater
2. Volume of Materials into Molding Dies
3. Wait for the cool Material
Step 3 : Output PLC
a.If 1001 = ON Then 0500 = ON.
