Description

📊 Product Technical Parameters

• Brand: WOODWARD
• Model: 8440-1978 (DSLC-2)
• Series: DSLC-2 (Digital Synchronizer and Load Control) Series
• Product Name: Advanced Digital Synchronizer and Load Control Module
• Country of Origin: USA
• Condition Status: Industrial Factory Original / Brand New In-Stock
• Dimensions: Standard industrial module format (approx. 215.9 mm x 184.2 mm x 58.4 mm)
• Weight: Approximately 1.4 kg (3.1 lbs)
• Original Region: United States
• Power Supply / Rating: 12/24 VDC auxiliary power supply (wide operating range of 8 to 40 VDC)

⚙️ Operation Specifications and Usage Methods

• Installation Preparation: Ensure all power sources to the electrical control cabinet are completely locked out and tagged out. Mount the DSLC-2 module securely inside a protective industrial enclosure, adhering to proper static-safe grounding protocols.
• Parameter Configuration: Connect a configuration PC to one of the communication ports using Woodward ToolKit service software to set up 1A current transformer (CT) inputs, potential transformer ratios, PID loops, discrete I/O, and network communication parameters.
• Operational Control: Monitor real-time system metrics, synchronizing states, and multi-unit load sharing across the network while the module handles automated frequency matching, phase alignment, dead bus closing, and active power distribution.

⚡ Startup and Shutdown Sequence

• Startup Sequence:
  1. Inspect all terminal wiring, confirming correct polarity and secure connections across the 1A CT inputs, potential transformers, and power lines.
  2. Energize the 12/24 VDC auxiliary power supply (8 to 40 VDC range) and verify that the module initializes cleanly without diagnostic fault flags.
  3. Start the prime mover and bring the generator up to rated operating speed and nominal voltage.
  4. Engage the automatic synchronization and load control mode to allow the DSLC-2 to manage breaker closure and active power distribution across the network.
• Shutdown Sequence:
  1. Initiate active load reduction via control commands or network signals to ramp down generator power output smoothly.
  2. Open the generator output circuit breaker to completely decouple the unit from the shared electrical busbar.
  3. Shut down the prime mover engine or turbine according to standard mechanical safety protocols.
  4. De-energize the auxiliary control power supply and measuring input lines once the system is fully offline.
