Preventive Maintenance

AMETEK Solidstate Controls developed a lifetime preventive maintenance schedule based on our testing, field experience and supplier recommendations. Our annual maintenance events provide cleaning, testing, calibration and parts replacement as identified in need or as part of predictive replacement. 

We offer three different PM packages based on the age of your equipment: annual (PM1), five year (PM5) and 10 year (PM10). No matter which service is due, each PM allows you to plan your outages ahead of time, so that you aren't scrambling when the time comes. Below is what you receive when you trust AMETEK Solidstate Controls to perform your preventive maintenance.

Pre and Post Inspection Interviews:
AMETEK Solidstate Controls will meet with the plant personnel to review any observations they have witnessed concerning the system’s performance. Any abnormal conditions or operations will be considered during the inspection and testing.

Detailed Service Report:
We will document the results of the service visit with a detailed service report that will be provided to the client. This report will include all recorded voltage, current readings, thermal imaging, pertinent system photos, as well as any issues found with recommended corrective actions.

System Cleaning:
The entire system will be cleaned using a vacuum cleaner brush attachment and/or dry forced air in order to remove dust and other contaminants that may lead to system malfunction. We will also clean the equipment cabinet and internal components including fans, printed circuit boards, capacitors, transformers and manual switches.

Visual and Thermal Inspections:
We visually and thermally inspect the system for evidence of wear, heat related stress, damage, loose or failed components due to aging, vibration or other environmental conditions. We will either correct abnormal conditions during the PM or review them with the client and schedule them for repair.

Recommended Scheduled Spare Parts Replacements and Software Updates:
To assure optimum performance and reliability of the UPS system, we recommend replacement of critical components as indicated in our brochure.

Battery Offerings:
We offer an array of battery services including testing such as capacity testing, acceptance testing and IEEE load testing. We are able to provide battery bank rentals and assist in the sizing, selection and installation of batteries as well as removal and recycling. Learn more about our full battery offerings. 

24/7 Support:
Our dedicated, factory-trained technical support team is available 24/7 to provide assistance with the operation or service of your systems. Our emergency phone line rings directly to our engineers and from there they will determine whether they can assist remotely or if a Field Service Engineer will need to be dispatched to the client's site. 

System Operational and Functional Testing:
We measure and record all critical system parameters, including input/output voltages and currents for control circuits, alternate and primary power sources, charger, inverter and static switch output. We will either repair abnormal conditions during the PM or review with the client and schedule for repair.

Performed at Every PM1
with client's permission

• General Tests

  • Have all critical components replaced based on their electronic life cycle

  • Be given a full diagnostic reading to ensure all critical system parameters are operating properly

  • Have its voltage and current readings calibrated with a True RMS Meter

  • Receive verification that all AC Caps are functioning correctly

  • Have a ripple current battery test performed to confirm it has less than a 5% amp hour rating

  • Go through a Low DC Voltage Disconnect simulation to test proper performance of the Aux Contact and Shunt Trip Circuit in the DC input Breaker

  • Be checked for balanced currents flowing into the Charger Bridge

  • Have the equipment operate in a simulated power outage to ensure the equipment and batteries function as designed if required to do so in a real unplanned outage

• Battery Chargers - Float/Equalize functions, load share function and alarm functions

• Inverter/Static Switches - Static Switch automatic transfer functions, alarm function, manual bypass transfer function and any other functional test deemed necessary by the service engineer to verify proper operation

• Visual Battery Inspection and Cell Voltage Readings - Comprehensive annual battery inspection and analysis completed in accordance with the battery manufacturer recommendations and applicable ANSI/IEEE standards. All critical parameters are measured, recorded and given in a detailed report

• Battery Continuity Test - Disconnect the battery charger and allow the battery to discharge into the inverter or site load momentarily

Performed at Every PM5

• Includes everything in a PM1 and recommended parts replacement as detailed in our Preventive Maintenance brochure

Performed at Every PM10

• Includes everything in a PM1, PM5 and recommended parts replacements as detailed in our Preventive Maintenance brochure

• Printed Circuit Board Replacement (PCBR) - Many circuit boards have electrolytic capacitors, which typically begin to break down after 10 years and the board functionality can become unreliable
