The scale is valid only when the actuator is inthe 0 position on clockwise motion.Use the long arm of the cross on the Aux Switch Adjustment (Figure 9) to point to the position ofswitch A. Use the narrower tab on the red ring to point to the position of switch B.Zero Span Control Signal Adjustment (-ZS option)EN44B2-ZS(-S) andEN88B2-ZS(-S) :For sequencing and theelectronic limitation of the angleof rotation.Use the U0 potentiometer to setthe offset (start point) between 0and 5 VDC.Use the ∆U potentiometer to setthe slope between 2 to 30 VDC.NOTE:The ∆U adjustment becomesvirtual when the offset and slopesetting is greater than 10 V. TheY input is limited to a maximumof 10 VDC. Above 10 V, theangle of rotation is reduced,providing the feature ofelectronic limitation of the angleof rotation.Ys [%]100EA0632R102 5 10 30 35 Y [V]∆UwU O1)4)∆U (max. 30 V)Figure 10.Ys Actuator position (100% = angle of rotation 90° *)Y Control input signalU0 Offset (start point)∆U Slope∆Uw Active voltage range (Ys change)* When the mechanical limitation of the angle ofrotation and self-adapt function are ON (100%does not equal 90°).3)2)YsUo U VSLOPE, U2 101630 24OFFSET, Uo0 12EA0633R235 4Figure 11.129-271 EAI/EN4-5 DEI, Inc.
