This practical guide shows you how to complete a signed, QR-verified Data Center Load Bank Test Report certificate in OhmCert Module #18 and how to troubleshoot non-compliant readings on site.
1. Step-by-Step OhmCert UI Workflow
- Open Module #18: Navigate to Data Center Load Bank Test Report from the Dashboard.
- Load a 1-Click Standard Annex Preset: Open the blue Standard Annex banner at the top and click a preset (such as "100% Full Load IST Acceptance Step (1000 kW Class G3)") to populate target limits automatically.
- Enter Your Field Measurements: Fill in the measured inputs (Step Load Applied, Rated Output, ISO 8528-5 Performance Class, Frequency Dip on Step Load, Voltage Dip on Step Load, Frequency Recovery Time, Test Duration at Full Load, Maximum Alternator Temperature, Coolant Temperature Drift in last 15 min). Blank inputs stay neutral
PENDING. - Complete the 16-Point Checklist: Grade each item, attach photos if needed, and export the SHA-256 signed PDF certificate.
2. Worked Numerical Field Case Study
Scenario: 100% Full Load IST Acceptance Step (1000 kW Class G3) (ISO 8528-5 IST) — Full 1000 kW load bank acceptance run for 120+ minutes..
- Step Load Applied:
1000 kW - Rated Output:
1000 kW - ISO 8528-5 Performance Class:
G3 - Test Duration at Full Load:
120 min
3. Engineering Troubleshooting: Corrective Actions When a Reading Fails
- Clean radiator cores, adjust fan belt tension, and check room air-intake pressure drop if coolant temperature drifts > 2 degC/15 min or exceeds 95 degC.
- Adjust electronic governor load-anticipation / turbo boost parameters if block-load frequency dip exceeds Class G2 (12%) or G3 (10%).
- Check fuel filters, day-tank transfer pumps, and injector balance if the set cannot sustain 100% kW without frequency droop.
