📊 Technical Datasheet Parameters

⚙️ Operating Standards & Installation Methods

• Handling Precautions: Observe standard electrostatic discharge (ESD) safety protocols when handling the controller module or connecting programming cables. Ensure all power sources are isolated before servicing.
• Mounting Integration: Mount the controller securely onto a compliant industrial panel or within an approved electrical enclosure, ensuring adequate clearance for wiring terminations and thermal dissipation.
• Wiring Verification: Double-check all terminal screw connections for power inputs, actuator feedback signals, control commands, and communication links to ensure reliable electrical continuity.

🔌 Strict Startup and Shutdown Sequence

• Pre-Power Inspection: Verify that all control wiring, actuator connections, and communication cables are firmly terminated and inspected before energizing the unit.
• Startup Sequence:
  1. Apply the primary operating power to the controller input terminals.
  2. Launch the Woodward Driver Interface Program on a connected PC to establish communication.
  3. Verify internal diagnostic indicators and load parameter configurations.
  4. Enable the control loop once system readiness and actuator response are confirmed.
• Shutdown Sequence:
  1. Command the system to a safe neutral or zero position through normal operational procedures.
  2. Disable the active control loop via software or hardware interlocks.
  3. Disconnect power supplies to the unit only after the actuator has come to a complete rest.

💡 Product Usage Guide & Maintenance Best Practices

• Software Configuration: Use the Driver Interface Program to fine-tune control loops, match varying actuator inertia and friction loads, and save backup configuration files for quick replacement workflows.
• Routine Diagnostics: Periodically check communication links and monitor real-time operating variables through the software interface to detect early signs of mechanical or electrical wear.
