9905-134 woodward Part NEW

Description

9905-134 woodward Part NEW

The ‌2301A Full Authority Speed Control‌ regulates the speed or load of diesel/gas engines or steam/gas turbines based on process demand or computer control signals (4–20 mA or 1–5 Vdc). Housed in a sheet-metal chassis with a single printed circuit board, all adjustment potentiometers are front-accessible.

‌Operational Modes‌:

• ‌Isochronous Mode‌: Maintains constant prime mover speed under load variations. Compatible with Woodward load sensors for load-sharing applications.
• ‌Droop Mode‌: Adjusts speed proportionally to load (via external potentiometer), ideal for infinite bus operations or parallel prime-mover configurations.

‌Integration & Safety‌:

• Seamless ‌PLC compatibility‌ via 4–20 mA speed-setting input. Engine shutdown prevention is ensured through configurable low-limit settings.
• Supports reverse-acting controls for compatibility with EGB/PG-EG governors’ ballhead backup/actuator systems.

System Requirements‌:

• 2301A electronic speed control unit
• External power supply
• Magnetic Pickup (MPU) for speed sensing
• Proportional actuator for fuel/steam metering

‌Voltage & Actuator Options‌:

• ‌High Voltage‌: 88–132 Vac / 90–150 Vdc
• ‌Low Voltage‌: 10–40 Vdc
• Forward- or reverse-acting actuator compatibility (see Table 1-1 for application-specific configurations).

‌Speed Configuration‌:

• Internal DIP switches (under steel cover) set the speed range based on MPU frequency.
• ‌Sensor Frequency Formula‌:Hz=(Teeth on Gear × RPM × Engine/Sensing Gear Ratio)60Hz=60(Teeth on Gear × RPM × Engine/Sensing Gear Ratio)​
• Select switch positions (1–4) to match MPU frequency ranges:
  • ‌Switch 1‌: 500–1500 Hz
  • ‌Switch 2‌: 1000–3000 Hz
  • ‌Switch 3‌: 2000–6000 Hz (default)
  • ‌Switch 4‌: 4000–12,000 Hz

Advanced Features‌:

• Process sensor/computer interface for demand-based 4–20 mA or 1–5 Vdc signal integration.
• Signal converter compatibility enhances system efficiency and operational flexibility.
• Configurable high/low limits for load limiting, minimum output, or failsafe operation during signal loss.

A ‌4-pole mini-switch‌ (lower-left PCB quadrant) aligns the MPU-sensed speed range with engine RPM. Prioritize the highest frequency within the desired speed range if exact governor-engine alignment is unachievable.
