Notes :
LS = Limit Switch or Micro Switches for the Detection of Wire Out.

Number Of Inputs and Output PLC applied :
1. Number Of Inputs PLC is 4 Input :
--- 1 Unit Input for Push Button Start.
--- 1 Unit Input for Push Button Stop.
--- 1 Unit Input for Micro Switches Wire Out.
--- 1 Unit Input for Motor Feedback Alarm.
--- Total Number Of Inputs PLC is Minimum 4 Input Unit.

2. Number Of Output PLC is 2 Output :
--- 1 Unit Output for Speed Control Motor ( ON / OFF Motor ) .
--- 1 Unit Output for Single Solenoid. It's Functions to Pneumatic Cylinder Wire Cutter ON ( Normally Cutter OFF).
--- Total Number Of Outputs PLC is Minimum 2 Output Unit.


Sequence PLC Programming for Spiral Binding Forming Machine :

Step 1 :
a. If Push Button Start = ON Then Speed Control Motor = ON.
b. If Speed Control Motor = ON And Timer0 = ON Then Speed Control Motor = OFF.
c. If Timer0 = ON And Speed Control Motor = OFF Then Wire Cutters = ON.
d. If Wire Cutters = ON And Timer1 = ON Then Wire Cutters = OFF.
e. If Wire Cutters = OFF And Timer2 = ON Then Speed Control Motor = ON.
f. Continuous Process.

Step 2 :
a. If Push Button Stop = ON Then Stop Process.
b. If Micro Switches = OFF Or Motor Feedback Alarm = OFF (Normally ON) Then ALL System OFF.
c. Data Set Value Timer0 = 3 Second ( Data Setting = 3 second (Can be Changed) ) for Spiral Length.
