⚠ No continúe hasta que la frecuencia y el voltaje de CA del generador sean correctos y estén dentro de los límites.

Tools: Voltímetro de CA calibrado, Medidor de frecuencia calibrado, Manómetro de combustible

  1. Verifique que el generador esté en modo OFF y el MLCB del generador en OFF (ABIERTO).
  2. Apague todos los disyuntores y cargas; abra el suministro de energía eléctrica al interruptor de transferencia.
  3. Con un voltímetro de CA verifique N1 a N2 (debe ser 240 V CA) y N1/N2 a neutro (120 V CA).
  4. Presione MANUAL; el motor girará y arrancará; registre la presión de arranque del combustible.
  5. Deje calentar cerca de cinco minutos, luego cierre el MLCB del generador y registre la presión de funcionamiento.
  6. Con voltímetro y medidor de frecuencia verifique E1 a E2 (238 a 242 V, 59.5 a 60.5 Hz) y E1/E2 a neutro (119 a 121 V CA).
  7. Ajuste el MLCB del generador en OFF y presione OFF; el motor se apagará.
