How do I correctly wire the SAS61 Series Electronic Valve Actuator?

[VictoriaAnn]

Wiring the SAS61 Series Electronic Valve Actuator correctly is crucial for its proper function. Here's a step-by-step guide: First, remove the actuator cover by unscrewing the cover screws with a No. 2 Phillips or flat-blade screwdriver to access the terminal block. Second, connect the wires to the terminal block following the connections in Figure 2 of the manual. These connections are: G0 for Neutral (-), G for Hot (+), Y for Positioning signal (0 to 10 Vdc/4 to 20 mA), M for Measuring neutral, U for Position feedback (0 to 10 Vdc), and Z for Positioning signal forced control (AC/DC ≤ 24V, 0 to 1000 Ω). After wiring, secure the actuator cover by replacing it and tightening the cover screws. It's important to verify that G0 and G are correctly wired for the actuator to function properly and for its longevity. If you notice a buzzing noise when the actuator reaches its setpoint, the G and G0 wires might be reversed; if so, switch them. For all possible wiring connections, consult the wiring diagram in Figure 3 of the manual. The specific connections you use will depend on your application. By adhering to these steps and referring to the manual's diagrams, you can ensure your SAS61 Series Electronic Valve Actuator is wired correctly for optimal performance.
