Schneider Electric (Erie) AT33A030 Actuator
The Schneider Electric (Erie) AT33A030 Actuator is a robust, 24Vac 3-wire floating actuator engineered for precise control within closed hydronic heating and cooling systems. Capable of modulating fluid flow in fan coil units, VAV re-heat, and unit ventilators, this non-spring return actuator is a standard in building automation for technicians who require reliable fluid management without a time-out feature. Its three-wire floating signal allows for exact positioning based on controller input, effectively optimizing regional airflow and temperature stability.
Built with high-temperature plastic and featuring wire lead connections, the AT33A030 is designed for simplified field integration. It is compatible with the Erie PopTop series valve bodies, allowing for a "snap-on" installation that eliminates the need for complex linkages or manual calibration. This allows contractors to mount the HVAC valve actuator even after the valve body is piped into the system. For systems requiring floating control signals from a DDC or thermostat, this unit provides consistent torque and performance in confined spaces or air handling units.
Key Benefits:
- Compatible with Erie PopTop valve bodies for tool-free, snap-on mounting.
- Reliable 24V floating control ensures precise modulation for VAV and fan coil applications.
- Compact, low-clearance design is ideal for installation in tight mechanical closets and units.
- Non-spring return operation maintains last position upon signal loss, preventing sudden system fluctuations.
- Pre-installed wire leads streamline the wiring process for faster field deployment.
Common Questions:
How do I wire this actuator for a 3-wire floating system?
The AT33A030 utilizes a 24Vac common, one wire to drive the motor open, and a third to drive the motor closed. Ensure your controller is programmed for three-wire floating signals to ensure the motor receives power only when positioning is required.
Does this unit require a manual reset?
No. As a non-spring return actuator, it is designed to hold its position. If manual overrides are needed for testing, use the manual lever to position the valve before powering the system.
Why is my actuator not responding to the 24V signal?
Verification of the 24Vac power supply is critical. Use a multimeter to check for voltage at the wire leads under load. If voltage is present but there is no movement, check the valve stem for binding or debris, as excess torque can prevent operation.
