Set up of FC electric limit switches
WITH POTENTIOMETER OPTION, FIRSTLY ADJUST THE POTENTIOMETER, THEN ADJUST THE LIMIT
SWITCHES CAMS.
The cams that actuate the limit switches start from the rotation of the acme / ball screw inside the actuator.
The following figure shows the relationship between the direction of advance of the push rod and the
direction of rotation of the shaft on which the cams are fixed.
AVOID ANY PUSH ROD ROTATION, CAUSING CHANGES OF ITS AXIAL POSITION!
IF THIS HAPPENS, THE RELATION BETWEEN AXIAL POSITION OF PUSH ROD AND SWITCHES SETTING
WILL BE LOST. IF A WRONG ACTION OCCURS, OR IN CASE OF DOUBT, PLEASE REPEAT THE SET UP OF
THE LIMIT SWITCHES FOLLOWING THE SET-UP INSTRUCTIONS BELOW.
FC 2 – open position
FC 1 – closed position
