SW1:Prioritycircuit
The slider switch SW1isusedtosetthedirectionoftheprioritycircuittoincreasing/increas-
ing(>>)orincreasing/decreasing(<>).
SW2:Directionofaction
The slider switch SW2 is used to set the direction of action of the actuator.
SW3andSW4:Positionfeedbacksignal
The slider switches SW3 and SW4 are used to determine the position feedback signal.
The position feedback signal can be used for the following ranges:
− 4to20mAor2to10V
− 0to20mAor0to10V
