WOODWARD PEAK200-HVAC (8200-1501) – Digital Speed/Actuator Controller for HVAC Fans, Blowers, and Engine-Driven Air-Handling Systems

The WOODWARD PEAK200-HVAC 8200-1501 is a compact digital governor and actuator controller typically used to keep rotary equipment—fans, blowers, small compressors, and engine-driven HVAC units—running at a stable, precise speed. From my experience, this model is chosen when you need tight isochronous or droop speed control, clean transitions, and a reliable current drive for Woodward electric actuators without overcomplicating the panel. You might notice that it fits well in retrofit scenarios where older mechanical governors need a robust, low-maintenance upgrade.

Company’s Order Placement Process and Guarantees

• Payment: 50% advance payment, full payment for delivery
• Express options: FedEx, UPS, DHL

Key Features

• Digital speed control (isochronous or droop): Keeps fan or blower RPM steady under varying load; tuning is straightforward in most cases.
• Magnetic pickup speed input: Works with standard MPU sensors typically used on engine flywheels and rotating shafts.
• Actuator current drive: Directly drives Woodward electric actuators (commonly 0–200 mA current output), reducing interface hardware.
• Analog setpoint and discrete commands: Accepts a 4–20 mA or 0–5 V setpoint plus raise/lower or run/stop inputs for quick on-site adjustments.
• Soft start and acceleration ramps: Smoother fan starts help protect belts, couplings, and bearings—especially valuable in HVAC air handlers.
• Alarm/relay output: A simple status output typically used for panel annunciation or system interlocks.
• Service/configuration port: Local service access (commonly RS‑232) makes commissioning faster.
• Rugged operating range: Built for industrial control cabinets with wide temperature tolerance.

Technical Specifications

Application Fields

In many cases the PEAK200-HVAC is used on:

• AHUs and large ventilation fans driven by gas/diesel engines in remote facilities
• Industrial blowers for dust collection, furnaces, or process air where stable RPM is critical
• Retrofits of older mechanical governors on small compressors or fan drives
• Packaged engine-driven HVAC units where simple, reliable speed control is preferred over full PLC complexity

“After replacing a worn mechanical governor, the PEAK200 stabilized our fan speed within minutes of tuning, and nuisance trips basically disappeared.” — Maintenance Supervisor, food processing plant

Advantages & Value for Procurement

• Reliability that reduces downtime: Solid-state control with proven Woodward actuator drive stage; fewer mechanical wear parts.
• Compatibility with installed base: Works with common Woodward actuators and MPU sensors, which typically simplifies retrofits and spares.
• Lower lifecycle costs: Stable control helps avoid belt slippage, bearing stress, and overspeed events—saving parts and labor over time.
• Straightforward commissioning: Service-port tuning and clear I/O reduce on-site hours; less dependency on custom PLC logic.
• Support and documentation: Widely deployed, which means technicians are usually familiar with setup and typical fault patterns.

Installation & Maintenance

• Cabinet standards: Mount in a dry, ventilated industrial control cabinet; keep away from heat sources and high-vibration zones.
• Power and grounding: Provide a clean 24 VDC supply (18–32 VDC range). Use proper chassis grounding and observe reverse-polarity protection practices.
• Wiring: Use shielded, twisted-pair cable for the MPU input; route low-level signals away from motor leads and contactors. Tighten screw terminals to the specified torque.
• Commissioning: Set base speed, choose isochronous or droop mode, then tune PID gains with the load you expect in operation. Enable soft-start to protect the drive.
• Routine maintenance: Periodically check connectors and grounding, clean dust from the cabinet, verify setpoint/feedback signals, and back up configuration via the service port.
• Safety: Lock out power before servicing. Confirm actuator travel is clear and interlocks are functional before live tests.

Common Supporting Components

• WOODWARD magnetic pickup sensors for flywheel speed sensing
• WOODWARD electric actuators (e.g., ProAct series, EG/EPG family) for throttle or vane control
• Engine throttle bodies or fuel racks compatible with Woodward actuator linkage kits
• Shielded signal cabling and panel power conditioning (24 VDC)

Quality & Certifications

• Manufactured under ISO 9001 quality systems
• CE compliant; UL/cUL recognition typically available for control equipment
• RoHS compliant design
• Manufacturer’s standard warranty: 12 months (365 days)
