Reading Ladder PLC Programming for Heater Controller :
Step 1 :
a.If 0000 = ON Then 1000 = Momentary ON ( Diff. Up).
b.If 1000 = ON And 0000 = ON And 1002 = OFF Then 1001 = ON ( Hold ON ).
Step 2 : Check Alarm Heater
a.If 0001 = ON And 1001 = ON Then T000 Activated.
b.If T000 = ON And 0002 = OFF Then SET 1002 = ON ( Hold ON ).
c.If 0000 = OFF Then RES 1002 = ON ( 1002 = OFF ).
See Picture to Set Value Timer for Stability Current from Power to Heater :
Step 3 : Temperature is Reached
a.If 0001 = ON And 1001 = ON And 0000 = ON And 1002 = OFF Then 1003 = ON ( Hold ON ).
b.If 0001 = OFF And 1003 = ON Then SET 1004 = ON ( Hold ON ).
c.If 1001 = OFF And 0000 = OFF And 1002 = ON Then RES 1004 = ON ( 1004 = OFF ).
Step 4 :
a.If 1001 = ON Then 0500 = ON.
b.If 1002 = ON Then 0501 = ON.
c.If 1004 = ON Then 0502 = ON.
