G0 System Neutral (SN)
G System Potential (SP)
Y Positioning signal for 0 to 10 Vdc/4 to 20 mA
M Measuring neutral
U Position feedback 0 to 10 Vdc
Z Positioning signal forced control
If the application requires a reverse-acting, modulating actuator (a control
signal of 0V corresponds to the valve being closed, and 10V to the valve
being open), then the Function Module (AZX61.1) must be ordered and
installed in the VA-045PNX024P with DIP switch 1 set to ON.
Parallel Control of Actuators
Up to 10 actuators can be driven in parallel from a single controller output
with a rating of 1 mA. Modulating actuators have an input impedance of
100KΩ.
Use either a Phillips head screwdriver or a flat-blade
screwdriver to remove the wiring compartment housing
cover for access to the terminal block and DIP switches.

Manual Override

Automatic Mode
When the motor drives the manual adjuster turns. In Automatic Mode, the
manual adjuster is used for indication of travel. If the manual adjuster is
held firm in this mode, there is no transmission of power to the gear train.
Manual Operation
When pushing the manual adjuster down (1), it engages and the actuator
can be manually operated.
When turning the manual adjuster in a clockwise/counterclockwise
direction (2), the actuator's stem extends/retracts. See Figure 15.
An overload protection prevents damage to the manual adjuster.
Setting the Position
When the black slide switch is pushed out, the manual adjuster remains
engaged.
When in this mode, do not turn the manual adjuster.
