Step 1 :
ALL Process ON/OFF
a.If 0.00 = ON Then 10.00 = ON (DIFU)
b.If 10.00 = ON AND 0.00 = ON AND 10.09 = OFF Then 10.01 = ON (ALL PROCESS ON)
c.If 0.00 = OFF (ALL PROCESS OFF)
d.If 0.01 = OFF AND 10.02 = ON Then 10.09 = ON ( ALL PROCESS OFF )
Step 2 :
Red Lights = OFF
Green Lights = OFF
a.If 10.00 = ON AND 10.01 = ON AND 10.03 = OFF Then 10.02 = ON
b.If 10.02 = ON Then 10.07 = OFF (RSET 10.07 = ON) AND 10.08 = OFF ( RSET 10.08 = ON )
c.If 10.07 = OFF Then 100.02 = OFF (Green Lights = OFF)
d.If 10.08 = OFF Then 100.01 = OFF (Red Lights = OFF)
Step 3 :
Digital Zero Reset = ON
a.If 10.02 = ON AND T0000 = ON AND 10.01 = ON AND 10.04 = OFF Then 10.03 = ON
b.If 10.03 = ON Then 100.04 = ON (Digital Zero = ON)
Step 4 :
Rotary container = ON / OFF
a.If 10.03 = ON AND T0001 = ON AND 10.01 = ON AND 10.05 = OFF Then 10.04 = ON (Hold ON)
b.If 10.04 = ON Then 100.03 = ON (Electric Motor = ON)
c.If 0.02 = OFF AND 10.04 = ON AND 10.01 = ON AND 10.05 = OFF Then 10.10 = ON (Check Sensor position = OFF)
d.If 10.04 = ON AND 100.03 = ON AND 10.10 = ON AND 0.02 = ON AND 10.01 = ON AND 10.06 = OFF Then 10.05 = ON ( Electric Motor = OFF )
e.If 10.05 = ON Then 10.04 = OFF
f.If 10.04 = OFF Then 100.03 = OFF ( Electric Motor = OFF )
Step 5 :
Weighing : GO/OK = ON/OFF
a.If 10.05 = ON AND T0002 = ON AND 10.07 = OFF AND 10.08 = OFF AND 10.01 = ON Then 10.06 = ON (Judgment OK/NOT OK)
b.If 10.01 = ON AND 10.06 = ON AND 0.03 = ON Then 10.07 = ON (SET 10.07 = ON) =>Weighing OK
c.If 10.01 = ON AND 10.06 = ON AND 0.03 = OFF Then 10.08 = ON (SET 10.08 = ON) =>Weighing NOT OK
d.If 10.07 = ON Then 100.02 = ON (OK)
e.If 10.08 = ON Then 100.01 = ON (NOT OK)
Step 6 :
Empty Containers
a.If 0.01 = OFF AND 10.02 = ON Then 10.09 = ON (ALL PROCESS OFF)
b.If 0.01 = ON Then 100.00 = ON (Yellow Lights = ON)
