Quality Control Process
Every Mk II unit is validated before shipment. We inspect the PCB for conformal coating integrity and terminal torque. Functional testing simulates grid loss and auto-start sequences. Load sharing logic is verified using a multi-genset simulator. Communication ports are tested for protocol compliance. Finally, the industrial automation unit is packed in anti-static shielding with foam inserts.
Replacement Pitfall Guide
❗ Check Firmware Version: Mk II has multiple firmware revisions. Mismatched versions cause communication failures in multi-unit systems.
❗ Verify TDU Compatibility: Not all TDU models work with all firmware. Check the compatibility matrix before ordering.
❗ Save Configuration First: Export all parameters via USB or Insight software before removal. The new unit ships with factory defaults.
❗ CAN Bus Termination: Ensure proper 120Ω termination at both ends of the CAN bus. Missing terminators cause intermittent data loss.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| Mk II | Direct | Drop-in replacement with enhanced features | |
| Mk II | Mk II (New FW) | Needs Adaptation | Verify CAN bus configuration and TDU compatibility |
- Benchmark: Synchronization accuracy typically ±0.1 Hz / ±0.5° phase angle.
- Benchmark: Load step response maintains voltage within 2% deviation.
