EQ Wave Configuration
This guide covers the configuration parameters for EQ Wave v1 sensors. Refer to the Installation Guide for hardware setup.
Network Settings
EQ Wave v1 ships with fixed network settings:
- IP Address: 192.168.10.10
- Subnet Mask: 255.255.255.0
- TCP Services: Port 1534 (CPOW waveform data), Port 1535 (PMon power metrics)
These settings are factory-configured and cannot be changed in the field with current firmware. The gateway’s sensor-facing interface must be configured on the same subnet (default: 192.168.10.2).
Future firmware updates will support automatic network configuration.
Power System Parameters
The following parameters are set at the factory based on your order specifications. Contact support@eq.systems to request changes.
System Type
- Number of phases: 1, 2, or 3
- Nominal frequency: 50 Hz or 60 Hz
- Nominal voltage: Typically 120V, 208V, 240V, 277V, or 480V
Current Sensor Setup
- Default configuration: Voltage-output current transducers (333 mV at full scale, e.g., Socomec Accu-CT)
- Alternative sensors (must be specified when ordering): Split-core CTs (5A secondary typical), Rogowski coils (100 mV/A output typical)
- CT ratio (e.g., 150:5 for 150A primary, 5A secondary)
- CT direction (ensure power flow polarity is correct)
Polarity Convention:
- CT Arrow: Points toward load
- Primary Current: Flows from source to load
- Secondary Connection: I+ connects to CT terminal marked with arrow
- Power Factor: Positive for inductive loads when properly connected
Voltage Scaling
Voltage Division Factor: 1335.833333
System Compatibility:
| System Type | Recommended PGA Setting | Overvoltage Margin |
|---|---|---|
| 600V Delta (L-L) | 1 | 57.4% |
| 480V Delta (L-L) | 1 | 96.8% |
| 600/346V Wye (L-N) | 2 | 36.3% |
| 480/277V Wye (L-N) | 2 | 70.4% |
| 240V Single-phase | 2 | 96.8% |
| 240/120V Split-phase | 4 | 96.8% |
Measurement Specifications
- Input Impedance: 68 kOhm differential
- Current Accuracy: +/-0.14% (excluding external sensor error)
- Phase Accuracy: +/-0.2 degrees typical
Sampling Parameters
- PMon update period: 12 cycles at 60 Hz / 10 cycles at 50 Hz (200 ms)
- CPOW frame rate: 500 packets/second (64 samples per packet at 32 kHz)
Verifying Configuration
After installation, verify the factory settings are correct for your site:
- Voltage readings: Compare displayed RMS voltage against a known reference meter. If readings are off by a fixed ratio, the voltage scaling may need adjustment.
- Current readings: Apply a known load and verify current magnitude and sign. Negative power indicates reversed CT polarity.
- Phase sequence: Confirm phase angles are approximately 120 degrees apart for 3-phase systems.
- Frequency: Should match your local grid (50 Hz or 60 Hz).
If any readings are incorrect, contact support@eq.systems with your measurements and the expected values.
