Description

The setup procedure steps of 9907-135 Digital Speed Control Module

9907-135 Configuration Procedure‌

‌Initial Power-Up‌
- Apply 18–35VDC power to terminals ‌TB1-1 (+) / TB1-2 (–)‌.
- Verify ‌STATUS LED‌ illuminates solid green (indicates boot completion).
‌Communication Setup‌
- Connect RS-485 interface to ‌TB2 terminals (A/B/Shield)‌ using shielded twisted-pair cable.
- Set baud rate via DIP switch ‌SW1-1/2‌:
  - OFF-OFF = 9600 bps
    ON-OFF = 19200 bps
  - OFF-ON = 38400 bps (default)
    ON-ON = Reserved

‌Parameter Initialization‌
- Launch Toolkit™ Software → Establish connection to module.
- Navigate: Configuration > Speed Control Settings:

  a. Set [Engine Type]: Diesel/Gas (select per prime mover) b. Adjust [Droop] = 0–10% (4% typical for generators) c. Configure [Speed Range]: 500–6000 RPM (match engine spec)
‌PID Tuning‌
- Access Tuning > PID Gains:

  Proportional (Kp): Start at 2.0 Integral (Ki): Start at 0.5 Derivative (Kd): Set to 0 (unless transient response required)
  
  ‌Execute step-test‌ → Refine values until overshoot <±1%.
‌Critical Safeties‌
- Enable Protection > Overspeed Shutdown:
  textCopy Code
  
  Set [Trip Level] = 110% of rated speed Set [Trip Delay] = 0.3 sec
- Activate Fail-Safe Mode via SW2-1: ON = Enable (force relay de-energize on fault).

️ ‌Safety & Validation‌

‌Grounding‌: Ensure chassis ground resistance ‌≤1Ω‌ (terminal ‌TB1-3‌).
‌Calibration Check‌:
- Run at 50%/75%/100% load → Confirm speed deviation ‌<±0.25%‌.
- Trigger overspeed test → Verify relay ‌K1/K2‌ opens instantly.
‌Environmental Limits‌:
- Operating Temp: ‌–40°C to +85°C‌
  Humidity: ‌5–95% non-condensing‌

‼️ ‌Fault Recovery‌

‌LED State‌	‌Action‌
‌Red Flashing‌	Communication error → Check RS-485 wiring
‌Red Solid‌	Critical fault → Review Toolkit event log
‌Off (Power On)‌	Verify input polarity; test supply voltage
