ARMY TM 9-6115-464-34AIR FORCE 35C2-3-445-2NAVY NAVFAC P-8-624-34(e) Slowly raise output frequency of power source GI until test lamps transfer. Test lamps shall transferat 46 ± 1 Hz (375 Hz for 400 Hz units).(f) Adjust output voltage of power source G1 to 132 Vac. Check for test lamp transfer points. Transferpoints shall be within 1 Hz of those of steps (d) and (e).(g) Adjust output voltage of power source G1 to 108 Vac. Check for test lamp transfer points. Transferpoints shall be within 1 Hz of those of steps (d) and (e).(h) Open switch S1 and repeat steps (d) through (g). Transfer points shall be 55 ± 1 Hz and 58 ± 1 Hz(380 ± Hz and 385 ± 2 for 400 Hz units).(10) Test permissive paralleling relay as follows:(a)(b)(c)(d)(e)(f)(g)(h)(i)(j)(k)(l)Install permissive paralleling relay into test circuit shown in figure 3–126.Check that switch (S1) is open, then energize power sources G1 and G2.Adjust power source G1 to obtain reading of 15 Vac on voltmeter (M1).Adjust power source G1 to obtain reading of 50 Hz on frequency meter (M2).Close switch (S1) and observe test lamp (DS1) and (DS2). DS1 shall be dark and DS2 shall beilluminated.Slowly reduce the voltage of power source G1 until the relay drops out (DS1 extinguishes and DS2illuminates). Drop out shall occur at 8 ± 1 Vac.Slowly increase the voltage of power supply G1 until relay pickup occurs (DS1 illuminates and DS2extinguishes). Pick up shall occur at a voltage not greater than 1 Vac greater than drop out.Open switch (S1) and adjust frequency of power source G1 to 60 Hz.Repeat steps (e) through (g) above. Relay drop out and pick up shall occur at the same voltages.Open switch (S1) and adjust the frequency of power source G1 to 400 Hz.Repeat steps (e) through (g) above. Relay drop out and pick up shall occur at the same voltages.Increase the voltage of power source G1 to 300 Vac for 2 seconds. There shall be no damage as aresult of this test.(11) Replace relays which fail to perform as specified.(12) Test electronic components assembly as follows: (See schematic diagram in figure 3-127).(a) Check resistance across terminals 1 and 2 and across terminals 3 and 4. Resistance should be asspecified. If it is not, replace the defective resistors as necessary.(b) Test capacitor (terminals 5 and 6). Replace, if defective.(13) Replace defective components of electronic components assembly using figure 3-127 as a guide,and Appendix A references for detailed soldering and replacement procedures.(14) If the wiring harness has sustained damage and requires repair or rebuild, refer to figure 3-128(50/60 Hz) or 3-129 (400 Hz) for layout, identification and material requirements and Appendix A fordetailed soldering and replacement procedures.3-262
