Factory setting:
30V span
0 offset
The offset (start point) and span of the control signal can be adjusted. The offset, Uo, can
be adjusted between 0 to 5 Vdc. The span, ∆U, can be adjusted between 2 to 30 Vdc.

NOTE: When the mechanical limitation of the angle of rotation and self-adaptive function are ON, 100% does
not equal 90°.
1.
Uo = 0V, ∆U = 2V: The minimum working range for Ys = 100%
2.
Uo = 5V, ∆U = 30V: The maximum working range for Ys = 100%

Example:
Open the actuator from 0 to 50% (45°) using a control signal of:
Umin= 2V to Umax= 10 V.

Actuator scale: Clockwise
Adjustment range for switches A and B:
Setting interval: 5°
Switching
hysteresis:
2°
Actuator Scale: counterclockwise
Dual Auxiliary Switch
DC24-132-TA,
DCM24-132-ZA
To change the settings of A and B:
NOTE: The scale is only valid when the actuator is in the "0" position on clockwise motion.
•
Use the adjustment tool provided with the actuator
to turn the switch adjustment dials to the desired signal setting.
