1 SERVO CONTROLLER INTRODUCTION: Sdtork Introduce Digital Servo Controller with several Features for all type of Valve Automation. AIM: Sdtorks main aim is to make automation in all industries so here we are introducing our Servo Controller to satisfy our customer with several Features inbuilt. We only the Manufacturer who thinks about customers requirement so now we are introducing our Servo Controller with Valve Opening and Closing Position with Digital Display. Open, Close and Run mode facility with feather touch button and LED Display Shown in the fig Position Servo Controller Open Run Cal Close Open Cal Close A/M Display LED Close Open Calibration

2 PROCEDURE: Make all the connections properly i.e. Motor feedback and current input. Now switch ON the instrument, the display reads the present value. To calibrate press and hold CAL (A/M) button for about 5 seconds, now the display reads CAL and starts flashing slowly. Then give Input of 4 ma and press CLOSE button on Servo the actuator starts rotating in close direction and display starts flashing little fast. After complete close Position the motor stops and again the display starts flashing slowly. Now give Input of 20 ma and press OPEN button on Servo, the actuator starts opening and the display flashes little fast again. After complete open position the motor stops and display reads CAL without flashing. Now press and hold CAL(A/M) button for about 5 seconds to come out of the calibration mode. The output current of 4-20mA will be calibrated automatically during this calibration process. For Setting the Hysteresis switch off the power and press the CAL Button and switch on the power servo will display H01 Increases the Hysteresis by pressing the open Button after setting the Hysteresis press the CAL Button to set the value what you have selected and if you want the pulse operation Switch off the supply and press the Close Button and switch on the supply the servo will read NO1 then to increase the pulse operation press the open button and set the value and press the CAL button to fix the value and you can see the pulse operation.

5 Operating Instructions Servo Controller controls Opening/Closing function of the Valve fitted with Electrical Actuator. Supply, Feed Back, Motor and Input connections should be properly wired as per the terminal details mentioned in the back panel. One key is provided to select Auto or Manual mode. Selected mode is indicated by LED. In manual mode valve can be operated by pressing the Open/Close feather touch keys provided on the front panel. In Auto mode valve operates depending upon the 4-20mA input variation. At 4mA the valve closes fully and at 20mA the valve opens fully. Accordingly for 4-20mA input variation valve operates close to open 0 to 100% linearly. The display indicates the percentage opening position of the valve from 0 to 100% accordingly. While valve opening/closing takes place the corresponding LED glows. 4-20mA feedback output is available for 0 to 100% valve operation. Calibration To calibrate the valve with controller auto calibration facility is provided. Connect the controller with actuator and confirm the feedback, motor and input connections are ok. To calibrate press and hold the CAL (A/M) key for about 5 seconds. The display reads CAL with flashing slowly. Now give input of 4mA and press Zero (close) key. The display flashes little fast and the valve starts closing. After full close the display flashes again slowly, now give the input of 20mA and press Span (open) key, the valve starts opening and after full open the display reads CAL without flashing. Now press and hold the CAL key for about 5 seconds to come out of the calibration mode. Now the valve is calibrated with controller and starts to operate as per the input given. Fault Indications If the feedback is not connected properly or the value of the feedback input is exceed the range the instrument displays FB with flashing. While calibrating if the feedback is not proper or input 4-20mA is exceed the range or input is not given as explained in the calibration procedure then display reads Err with flashing.

6 Troubleshooting Symptom Cause/ Check Point Remedy Actuator not functioning Check power supply Check power supply Actuator wiring not proper Correct wiring Incorrect Voltage supply Check the input supply voltage suitable for actuator Overload Check operating thrust and rated thrust Control Signal not available Check control signal and provide 4-20 ma Fault in electronics/ failure of electronic Consult Factory card Actuator does not open or Check limit switch settings Calibrate Limit close completely switch settings High valve torque required Select actuator having higher torque rating Valve choked/ locked Open and Clean valve internally Motor runs but valve does Mechanical connection between actuator Repair or contact not move and valve stem broken sdtork. Motor does not run Incorrect voltage Provide correct voltage Improper wiring Correct wiring Valve does not open or Disturbance in setting of travel limit Reset Travel Limit close completely switches switches with cam
