Pre-Operational Checks

1. Hardware Inspection
   • Verify LED indicators:
     • PWR (Green): Steady = 24-250V DC supply OK
     • ALARM (Yellow): Flashing = Self-test in progress
   • Check terminal tightness:
     • Power terminals (X1:1-2): 0.8 Nm torque
     • Binary inputs (X3:1-8): 0.5 Nm torque
2. Software Configuration

   Required files: - PCM600 project file (*.prj) - CID file (CRC32 verified) Connect via USB/LAN port (192.168.1.10 default)

   

Operation Sequence

Step 1: Power-Up Procedure

1. Apply auxiliary voltage (Range: 24-250V DC) 2. Observe startup sequence: • 0-2s: Hardware self-test • 3-5s: Firmware checksum verification • 6-8s: Parameter loading from NVROM 3. Confirm "READY" status on LCD

Step 2: Functional Testing

Step 3: Event Logging

1. Press NAVIGATE button → Select "Event Recorder" 2. Trigger test events → Verify timestamps (μs accuracy) 3. Export via USB: • COMTRADE format for Disturbance Recorder • CSV format for sequence-of-events

Safety Protocols

Critical Warnings

• Never disconnect CT circuits under load (risk of 10kV arcing)
• Maintain 50mm clearance from high-voltage conductors
• Disable autoreclose function before testing (Parameter 8531)

Lockout/Tagout Requirements

1. Isolate all CT/PT inputs 2. Apply safety ground (X1:PE terminal) 3. Tag with "TEST IN PROGRESS"
