LED Status Indicator Lights:
 Green NORMAL VOLTAGE (V Normal) indicator — signals when output voltage is available to the
customer load. This indicator activates when the SW200 toggle switch is set to the RUN position
and stays on as long as there is voltage available to the customer load.
 Yellow LOW VOLTAGE ALARM (LV Alarm) indicator — signals that the customer output voltage is
low, with thresholds based on the Sentinel model. It remains unlit when there is no alarm. Low
Voltage Alarm parameters vary between models as follows:
o 12V Models — alarm turns on when output voltage falls below 11.0 Volts and turns off when
voltage rises above 11.5 Volts.
o 24V Models — alarm turns on when output voltage falls below 22.0 Volts and turns off when
voltage rises above 23.0 Volts.
 Red PREHEATER (Preheater) indicator — indicates when the preheating element is turned on and
when to apply fuel gas to the Sentinel TEG. Refer to Section 4.2 for full start-up procedures.
