Eaton 93T — is a three-phase online double-conversion UPS designed to provide reliable power to critical facilities: data centers, industrial enterprises, hospitals and telecommunications systems. The model is characterized by high efficiency (up to 96%) and a flexible architecture with the possibility of parallel redundancy and battery capacity expansion. Eaton 93T diagnostics provide timely detection of technical faults and help maintain stable operation in conditions of load changes and network outages.
What diagnostics include
Inspection / audit
- Visual inspection of the housing, display, keyboard, indicators, ventilation systems.
- Assessment of UPS installation, correct connection of power, load, battery modules.
- Analysis of operating parameters: temperature, humidity, dust pollution of the room.
Electrical tests
- Measurement of input voltage, frequency, harmonics, checking the stability of the mains power supply.
- Control of output voltage and frequency in various UPS operating modes (online, bypass, autonomy).
- Simulation of loss mains power supply with assessment of the transition to the inverter and the stability of the output voltage.
- Checking the double conversion mode at different loads and frequencies.
Inverter / bypass / charge
- Inverter testing: output signal shape, harmonic level, operating temperature under load.
- Static and service bypass diagnostics: continuity of power supply, switching speed, presence of failures.
- Checking the charger: voltage, current, battery charging modes parameters.
- Analysis of event logs, accidents and system logs via display or software.
Battery system (battery system)
- Inspection of battery modules: physical condition, absence of corrosion, swelling, traces of leakage.
- Measurement of the voltage of each cell, control of charge uniformity and temperature.
- Autonomous operation test: determining the actual power supply time under load.
- Assessment of the degree of battery wear (SOH) using a battery monitor or by manual measurements.
Cooling
- Checking the operation of fans: speed, noise, possible bearing failures.
- Monitoring temperature sensors in the area of power modules, inverter, charger.
- Assessing the condition of air filters, determining contamination, ensuring sufficient air flow.
Communications / monitoring
- Testing the LCD interface: correctness of parameter indication, access to logs, control.
- Checking the operation of network interfaces: USB, RS-232, SNMP, Modbus (if available).
- Integration with Eaton Intelligent Power Manager, Power Xpert, SCADA systems.
- Checking dry contacts and alarms.
Technical report
- Full report with measurement results, analysis of the condition of batteries, inverter, cooling and communications.
- Fixing detected deviations, possible problems, recommendations for troubleshooting.
- Proposals for firmware updates, battery replacement, scheduled service.
When diagnostics are needed
- Regularly, at least once a year, to prevent and prevent emergency shutdowns.
- After replacing or adding battery modules, changing the system configuration.
- When error messages, unstable operation or reduced autonomy time are detected.
- Before conducting scheduled audits or power supply modernizations.
