ELECTRIC ROTARY GEAR MOTOR Series AB1... The AB electric rotary gear motors are newly conceived and have been specially designed to be installed on industrial and residential combustion systems. They are particularly suitable for the control and regulation of modulating valves, butterfly valves, dampers and other fluid regulation systems requiring an angular positioning within 90° or 180°. The electric motor is unipolar and bidirectional with high static and maintaining torque for 3- position operation.

CAM ADJUSTMENT For cam adjustment the proper lever supplied with the gear motor equipment is to be used. Use the lever from the right side, introducing the pin into one of the bores on the sides of the blue cam and lever it to the desired position. If the blue cam is in a behind position, use the lever on its curved side to move the blue cam to a more suitable position to perform adjustment. Adjustment is possible in both directions along the whole rotation angle of the cam shaft. Remove the lever before servicing. Note If a potentiometer is installed it is necessary to reset its friction...
