Actuator Install Instructions

VA9104-xGA-3S Series Electric Non-Spring Return Valve Actuators Installation Instructions 7
VA9104-GGA actuators are factory set for Direct
Acting (DA) mode and for a DC 0 to 10 V input control
signal. In DA mode, a minimum control signal drives
the actuator to the full Counterclockwise (CCW)
position, and a maximum control signal drives the
actuator to the full Clockwise (CW) position.
For Reverse Acting (RA) operation, a minimum control
signal drives the actuator to the full CW position and a
maximum signal drives the actuator to the full CCW
position. To change the factory settings, remove the
actuator cover and adjust the switches on the circuit
board as shown in Figure 14.
