TM 9-6115-666-13The exciter voltage and therefore the phase/line voltages are adjusted with the VOLTAGE ADJUST po-tentiometer (R3) to 120/208 V, and displayed on the VOLTAGE meter (P6). They are applied to recep-tacles L1 (0A), L2 (0B), L3 (0C) and N.The temperature of the stator winding is monitored by a thermistor (control line), which is connected tothermistor relay F12 in the control cabinet. If the stator winding reaches or exceeds a temperature ofapproximately 302 °F (150 °C), F12 shuts down the Generator Set 150 kW and the GENERATOR OVERTEMPERATURE illuminated pushbutton switch (H10, S6) lights up. The alarm signal is applied to PAR-ALLEL OPERATION receptacle J9, and is sent via the EPP III to the ECS.Key to Figure 1-4MonitoringSetpointActual valuePreheatFigure 1-4 Generator Set 150 kW, Block Diagram.1 - 1 7
