Test shall be performed by the manufacturer using certified flow measurement devices and shall be witnessed by a representative of the Test and Balance Firm. Demonstrate deflection limit of 1/200th and confirm fan/motor vibration limits. The cost of testing shall be borne by the manufacturer.
After assembly, fan and motor shall be given an electronic vibration analysis along with the variable frequency drive) either at the air handling unit or VFD manufacturer's factory, while operating over the entire speed range.
Vibration amplitude and frequency shall be recorded in the horizontal, vertical and axial planes.
Maximum allowable variation amplitude is 1.0 mil. Full range of frequencies (500 to 50,000 cycles per minute) shall be scanned to detect misalignment, bearing defects, mechanical looseness or foundation weakness.
Each bearing shall be tested.
Fans with VFDs shall be checked from 15 percent to 100 percent of the rated speed.
"Lock-out" ranges may be used to correct up to two ranges of excess vibration. The span of each "lock-out" range shall be limited to an effective fan speed of 50 RPM. Any "lock-out" ranges used shall be clearly identified in the test report and shall be prominently displayed on a typed, laminated legend mounted inside the VFD controller cabinet.
