YES, BUT IT IS NOT PERMANENT REMOVE THE MAIL LINE (FORM THE
POSITIONER)TO THE CV AND GIVE THE SUPPLY PRESSURE.
TUNNING IS REQUIRED FOR EXACT PERFORMANCE(Eg. YOUR CV HAVING
2% ERROR ,YOUR CONTROLLER IS GIVING 23% CLOSE BUT YOUR CV
WILL CLOSE 25% IT WILL AFFECT THE PROCESS) AND PERFECT
SEATING OF GATE.
