Electronic Control Panel

This is the real Control Part of the attachment. It comprises of two major divisions; a.) Motor Controller - it has a CPU, a Stepper Drive, a Power Supply and a user friendly keyboard with display. b.) Temperature Controller - this controls the temperature of the heater plate. It has as PID type temperature controller and a 3 phase solid state relay card to drive the power of the heater plate. 

1. High Voltage Power Supply- This part is located in the left most slot of the mother board. It has a Red colored LED (light) on this. The light glows when the power is , switched ON. Output voltage of this card is 55 volts and 70 volts D.C.
2. Low Voltage Power Supply- This is inserted in the 2nd slot of the mother board. It has a green colored LED on it. Output voltages of this part are -5v, 15 v,5v D.C.
3. CPU- This card contains the micro controller, which is responsibie for the total, control. It has a gray colored flat cable, 'which goes to the keyboard and display. Location of this part is third slot on the motherboard.
4. Stepper Drive- This part supplies power to the stepper motor. Its location is fourth slot of the motherboard. Failure of this card results in power failure of the motor.
5. Temperature Controller- This device is Em advanced temp. Controlier with PID control technique. It controls the temperature of the heater plate.
6. Solid State Contactor- It is mounted on an insertable card. Its location is in the fifth slot of the motherboard.
7. Keyboard & Display- This is mounted on the front plate of the control panel. It is used to feed and see the variables of the foil pulling.
8. MCB- It is located on the left wall of the control panel. It is used to disconnect the three phase power of trreheater plate.
9. Motherboard- This holds all the electronic cards and connects them to each other as well as the external devices.
