The days are growing longer as the flowers start to bloom in the midst of seasonal showers and spring is officially here. With spring in the air, you may be catching those spring-cleaning vibes. Believe it or not, your AMETEK Solidstate Controls’ Uninterruptible Power Supply (UPS) system can benefit from spring cleaning. Below is our spring-cleaning checklist:
- Clean your systems – Is your system collecting a dust bunny or two? It is good practice to vacuum and clean your assets on a regular basis. Our systems are built to withstand harsh environments but keeping the environment of your systems as clean as possible will help ensure their longevity.
- Check to see if you’ve scheduled your annual Preventive Maintenance (PM) – No time to vacuum and do the required annual preventive maintenance on every unit? No worries, let our factory trained field engineers with over 250+ years of combined experience handle the dirty work. As part of your scheduled PM, we make sure the system is clean, but cleaning isn’t the only services your AMETEK Solidstate Controls’ assets require. Below are just a few of the key things we do during your scheduled maintenance:
- Test:
- Aux Contact and Shunt Trip circuit in the DC input breaker by simulating low DC
- All alarm setpoints to ensure proper alarming and verify they are set at the correct setpoints and time delays
- Free running frequency of the Inverter to ensure it is within +/- 2% of 60 HZ to ensure proper sync reference to bypass source feed, if not adjust the frequency
- A simulation of full loss of power to the UPS (black plant) to make certain UPS doesn’t transfer and maintains load as required in an emergency
- Over temperature thermal couple to make certain the inverter shuts down and seamlessly transfers to bypass and opens the DC input breaker
- Ripple current on battery to ensure less than 5% Amp hour rating of battery
- Check:
- Perform Infrared imaging of all magnetics and bridges
- Measure and record system voltage, current and frequencies
- 480 input voltage for balanced currents into the charger bridge
- All AC caps are functioning by taking the voltage reading across the cap bank
- Loose connections, signs of overheating and/or other harsh environmental impacts on the system
- Fans for proper rotation and air flow
- Output power is a true Sinusoidal clean sinewave
- Alarm history
- Replace
- Critical PCB relays
- Pilot lights (incandescent)
- Fans (10-year service – PM10)
- Fuses (PM10)
- Capacitators (PM10)
We’ve developed this lifetime annual preventive maintenance schedule for our equipment through our testing, field experience and supplier recommendations. This maintenance ensures your systems are running at peak performance and ready to protect your critical loads that your facility requires to operate safely and consistently. Equipment maintained per our recommended schedule benefit from an extended warranty coverage that helps keep unplanned maintenance costs to a minimum.
- Take inventory of your spare parts – Does your spare parts inventory need some TLC? Let our experts help you purge and organize. They can help you conduct an inventory assessment of your spare parts and recommend what you can dispose of, what parts remain viable for each of your assets and let you know what spares you may need to purchase.
- Consider a Comprehensive Service Agreement (CSA) – Spring cleaning checklist have you feeling overwhelmed? We’ve designed three levels of multi-year service agreements to support your preventive maintenance schedule and ensure your critical power equipment functions as intended.
