Read and record allinstrument readings.(i)NOTEThis step is not applicable to generator sets having governors that utilize a threadedshaft and lock (nuts) or other operator speed alignment.Repeat 4-16c (1) and 4-16c. (2) (a) through (f) for each frequency.d. Results. The data sheet shall show the maximum and minimum frequencies attained at rated 109d, themaximum and minimum attainable frequencies at no load and actuation of the protection devices (if applicable).Compare these results with the requirements of table 4-1.4-16. OVERSPEED PROTECTIVE DEVICE TESTa. General. To assure that adequate protection is afforded the generator set against overspeeding, theoverspeed protective device must operate properly.b. Apparatus. A frequency meter or tachometer as described and illustrated in MIL-HDBK–705, Methods104.1 or 109.1 shall be required.c. Procedure.(1) Preparation for Test. Connect the frequency meter in accordance with the applicable figure ofMIL-HDBK-705, Method 205.1, Paragraph 205.1.9 or utilize the tachometer in accordance with themanufacturer’s instructions. Electronic governor and throttle stops must be deactivated.(2) Test.(a) Start and operate the generator set at rated speed (frequency), rated voltage and no load.(b) Slowly increase the engine speed until the overspeed protective device actuates. Record the speedof the generator set at this point, and the malfunction indicator light indication.CAUTIONDo not operate the set in excess of 125 percent of rated speed or as otherwise limitedin the procurement document. Failure to observe this caution could result in damage tothe equipment.(c) Attempt to start the set. Record if starting is achieved. If the set did not start, reset the overspeedprotective device.(d) Compare the test results with requirement of table 4-1.4-16
