Parameter
Meaning
Typical Range
Alt Current
The electric current in Amperes that is being
generated by the WhisperGen
TM
alternator. Positive
values indicate current generation and negative
values indicate current flow to the WhisperGen
TM
from the battery bank during cranking.
12V: -20 to 75A.
24V: -10 to 37A.
Air %
The power applied to the air blower as a
percentage of the maximum power that can be
applied to it. The higher the air flow rate, the higher
the combustion rate.
0 to 100%.
Bus Voltage
The voltage across the electrical terminals of the
WhisperGen
TM
.
12V: 10 to 15.5V.
24V: 20 to 31V.
Coolant Temp
The temperature in °C of the coolant. The coolant
temperature reflects the temperature of the engine
block.
-10 to 85°C.
Clamp Current
The excess electric current in Amperes being
diverted into the "clamp", an electric water heating
element located inside the WhisperGen
TM
enclosure.
0 to 70A.
Clamp Voltage
The voltage setting of the "clamp" system.
12V: 12.2 to 16.3V.
24V: 24.85 to 32.7V.
Exhaust Temp
The temperature in °C of exhaust gases between
the burner and exhaust heat exchanger.
-10 to 550°C.
FID Current uA
The current in µA flowing between the FID (flame-
ionisation detector) electrode and the burner shell.
A large current indicates a good stable flame in the
burner and correct FID operation.
0 to 10µA.
Fuel Cut Off
The position of the automatic fuel isolation valve
located inside the WhisperGen
TM
. It should be ON
when the WhisperGen
TM
is operating.
ON or OFF.
Fuel Metering
The operating state of the fuel pump. It should be
ON when the WhisperGen
TM
is operating.
ON or OFF.
Fuel Frequency
The rate at which fuel is pulsed into the burner. The
fuel pulse rate is adjusted in relation to power
demand and the air/fuel ratio.
2 to 16Hz
Glow Plug
The operating state of the glow plug. The glow plug
is turned ON as required during the start-up of the
burner.
ON or OFF.
Isolate Relay
The position of the main electrical isolator relay
located inside the WhisperGen
TM
. It should be ON
when the WhisperGen
TM
is operating.
ON or OFF.
Power Relay
The power supply to ancillary components such as
the fuel pump, coolant pump, etc. The power supply
should be ON when the WhisperGen
TM
is operating.
ON or OFF.
O2 Value
The quantity of oxygen in the exhaust. This reflects
the air/fuel ratio.
200 to 2500.
O2 Ave Error
The averaged difference between the air/fuel ratio
set point and the actual ratio. The smaller the
difference, the more stable the burner.
2 to 400.
Software Ver
The version of software the WhisperGen
TM
is
operating on.
A five-digit number.
