PREVENTATIVE MAINTENANCE INSPECTION (PMI) PLAN
The contractor shall develop a PMI plan that includes all of the following items:
Visual Inspection & Cleaning
Technicians shall perform a complete visual inspection and cleaning. Broken or damaged parts shall be replaced as necessary. Drives shall be inspected for at a minimum ambient temperature, dust, dirt, moisture, evidence of overheating, corrosion, integrity. Capacitors shall be checked for leakage. Conductors and parts shall be checked for proper insulation. Drives shall be cleaned using vacuum or compressed air as required. Filters shall be cleaned or replaced. Power connections shall be re-torqued to manufacturer s specifications. Contractor shall check circulating fans for signs of bearing failure or foreign objects internally.
Cooling
Fans shall be energized and tested for airflow. Heat sinks and air passages shall be inspected to detect blockage or broken/cracked components. Fans shall be replaced as necessary. Air conditioners shall be checked for proper cooling.
Line Reactors, DC Link Reactors, Isolation Transformers
Reactors and transformers are inspected for wear, insulation breakdown, connections, and proper conduction. Transformer voltages shall be checked for proper amplitude and balance. Inspect DC bus capacitors for bulging and leakage.
Operator Interface
The keypad or other operator interface shall be checked for display, keypad, proper communication, and fault history log. Contractor shall take action, as indicated, for fault indications.
Power-On Test
With power applied to the drive, the DC bus shall be checked for correct voltages and currents. Incoming AC voltages shall be checked for proper amplitude and balance. The DC bus shall be checked for voltage and excessive ripple voltage. Output voltages shall be checked for amplitude and balance. All values shall be compared with previous results to assess the rate of deterioration. Contractor Technicians shall look for evidence of unusual vibration or noise.
Harmonic Filters
Components shall be inspected for integrity, insulation breakdown, and connections. Line voltages and currents shall be verified for proper balance. Load voltages and currents shall be verified for balance and amplitude. Currents and voltages at the capacitors shall also be checked for balance and integrity. Capacitors shall be inspected for bulging, leakage, loose connections, etc. Current harmonics shall be measured and verified.
Converter Section
Each diode shall be isolated and tested for proper conduction and reverse voltage blocking capability. Connections shall be inspected for tightness and corrosion.
Inverter Section
Each transistor, or other switching device, shall be isolated and tested for proper conduction, commutation, and reverse voltage blocking capability.
Capacitors
Excessive ripple on the DC bus can cause erroneous operation and drive failure. Capacitors shall be isolated and tested to assure that they meet the manufacturer s specifications. Defective capacitors shall be replaced individually, based on Contractor s assessment, all capacitors shall be replaced for extended operating life. Bleed-off resistors are also checked for continuity and integrity.
Parameter Settings
Programming parameters shall be checked, as required, to assure correct settings. Alarm and fault logs shall be viewed to find evidence of previous faults. Change logs shall be viewed to indicate any parameters which have been inadvertently changed since the last maintenance visit. All inputs and outputs, digital and analog Input/Output (I/O), shall be tested for calibration and correct operation.
Pre-Charge Circuit
The pre-charge circuit protects the capacitors and DC bus from damage. A faulty pre-charge circuit can lead to DC bus failure, and even explosions. The pre-charge resistor shall be tested for integrity and proper resistance. The bypass contactor (or solid-state bypass) shall be tested for correct operation and contact wear.
Firing Test
While the drive is running, an oscilloscope shall be used to verify correct wave form on each of the output phases. Control voltage shall be checked and verified.
Load Test
The drive shall be run under load (where practicable). Currents and Voltages shall be measured for proper balance and amplitude. Voltage and current readings shall be verified on the keypad.
Enclosures & Build-ups
Maintenance of enclosures and build-ups varies according to the application. Typical maintenance shall include visual inspection, cleaning, fan inspection and/or replacement, replacing failed pilot lights, rotation verification and contact inspection on bypass contactors, calibration of analog transducers, tightening of electrical connections, damaged terminal blocks, etc. The replacement of fans shall be done on an as needed basis, by separate purchase order, at price indicated on the Price Schedule.
Infrared Scan
An infrared heat scan shall be done on the VFD s and/or associated power equipment. The thermal imaging report shall include an infrared image of the VFD and/or associated equipment along with digital hot-spot temperature, color image showing temperature profile within the cabinet, and a problem report describing any abnormalities found.
