Schneider Electric (Erie) AT23A00T Actuator Motor

The Schneider Electric (Erie) AT23A00T Actuator Motor is a high-performance floating signal actuator designed for precise fluid control in closed hydronic systems. Engineering a reliable three-wire floating control architecture, this 24Vac unit integrates time-out logic that automatically terminates the control signal after three minutes of continuous operation at 60 Hz, preventing motor burnout and gear train fatigue. The normally open spring return mechanism provides a critical fail-safe, ensuring the valve returns to its default position upon power loss, a vital feature for PopTop zone valve applications in fan coils and VAV reheaters.

Constructed with a magnetic clutch, the AT23A00T minimizes internal wear and maximizes the lifecycle of the gear assembly. This Erie PopTop actuator is specifically designed for seamless field installation; it can be quickly snapped onto compatible VM series valve bodies without the need for complex linkages or calibration. The motor operates within an ambient temperature range of 35°F to 125°F and includes a manual operating lever that doubles as a position indicator, allowing contractors to verify functionality during initial setup or system troubleshooting.

Key Benefits

• Fail-Safe reliability: The normally open spring return functionality ensures system safety during power interruptions.
• Enhanced Durability: Integrated magnetic clutch reduces mechanical stress on the actuator motor components.
• Simplified Installation: The PopTop design allows for tool-free mounting to the valve body after piping is complete.
• Operational Efficiency: Built-in three-minute time-out logic prevents unnecessary motor operation and energy waste.
• Field Monitoring: Manual lever and position indicator provide immediate visual confirmation of the floating signal status.

Common Questions

How do I wire the AT23A00T for a 3-wire floating system?
The AT23A00T requires a continuous 24Vac supply. The OPEN and CLOSE control signals share the COM terminal with the power supply. Always ensure your controller’s time-out logic matches the actuator's internal 3-minute sequence to avoid hunting.

Can this actuator be used on steam applications?
While the Erie AT23A00T is optimized for hot and chilled water systems up to 200°F, it is typically rated for 15 psig steam when paired with specific high-temperature valve bodies. Check the fluid temperature limits for your specific configuration.

What happens to the valve position if 24Vac power is lost?
Being a spring return normally open model, the actuator will mechanically drive the valve to the open position if the 24V power supply is interrupted for more than two seconds.
