• Complete a resistance check per the instructions in the manual.
• NOTE: SGCTs may not have completely shorted, and still could read in the kΩ range – Any devices with low suspect readings should be changed.
• Check the LED status of the SGCT gate driver card for abnormal readings.
• Complete a Gating Test mode check on the devices.
• Verify the associated 20V power supply is powered and active.
• Verify all the power connections to the SGCT firing card are seated properly.
• For nuisance faults, contact the factory about extending the Diagnostic Delay

The advantages and disadvantages of three types of UPS power batteries:
1. Open lead-acid battery:
Advantages: Less investment, longer lifespan compared to maintenance free batteries, and lower temperature requirements.
Disadvantages: Maintenance is complex and requires a dedicated battery room. Corrosive gases are discharged and must be initially charged on site for 50-90 hours, requiring dedicated maintenance personnel.
2: Maintenance-free batteries:
Advantages: No need for maintenance such as adding liquid, can be transported in a fully charged state, and does not require dedicated maintenance.
Disadvantages: Failure to recover charging in a timely manner can damage the battery, make it more sensitive to temperature, have a shorter lifespan, and be more expensive than lead-acid batteries.
3: Nickel chromium batteries:
Advantages: Low maintenance requirements, long lifespan, insensitivity to temperature, and no harmful gas emissions.
Disadvantage: The most expensive among the three types of batteries.
