Common Equipment Failures Solved

• LCD no screen after power on: Check DC battery positive/negative wiring looseness, confirm DC8-36V normal voltage range
• ATS fails auto start when mains lost: Verify AUTO mode activated, re-calibrate mains voltage detection threshold via USB software
• PC cannot connect via USB cable: Confirm USB driver installation, check cable wiring integrity
• Need remote APP/web monitoring: Replace with DC42DR MK4 model with RS485 Modbus port
• Grid-connected genset reverse power fault alarm: DC42D MK4 has no ABF anti-backfeed function, upgrade to DC42DR-ABF MK4
• Cannot read EFI engine ECU fault codes: No CAN bus, select DC42CR MK4 for electronic injection engines
• Need independent power kWh display: Match GV59R 3-phase multi-function power meter for separate energy statistics
• Marine cabinet long-term high humidity environment: IP65 waterproof design meets standard marine land cabinet use requirements
