•
During the burn if the temperature in the waste chamber exceeds programming
for SP1 on lower FDC the “B1” burner fuel will be shut off until the temperature
drops 90 degrees (90 degrees difference is the maximum the control can be set
for on any FDC output). Then the burner will automatically refire.
•
During the burn if the temperature in the waste chamber exceeds programming
for SP2 on lower FDC the “B2” burner fuel will be shut off until the temperature
drops 90 degrees (90 degrees difference is the maximum the control can be set
for on any FDC output). Then the burner will automatically refire.
•
During the burn if the temperature in the secondary chamber exceeds upper FDC
SP3 (HI limit) all burners fuel will be shut off until the temperature drops 90
degrees. Then the burners will automatically refire.
•
During the burn if the temperature in the waste chamber exceeds programming
for SP3 on lower FDC the water spray will activate until the temperature drops 90
degrees (90 degrees difference is the maximum the control can be set for on any
FDC output).
•
Note on some models any FDC output not used can be utilized by the customer.
This is a dry light duty amp load contact.
•
As the waste burns the temperatures rise and then taper back over time.
•
When the Timer expires or power is turned to OFF all burners will stop firing.
•
Note on gas burners; a thermal sensor monitors temperature in the burner body.
When the burner power is off for any reason and heat trips this sensor it will start
the burner’s fan to cool the burner. This is to counter heat that may backflow
from the internal chambers for any reason.
•
Note on gas burners; a manual switch is on their housing box. The switch can
be used to over-ride the FDC settings and shut off the burner’s fuel. Manually
using the toggle switch may be done with the two lower burners if the waste gets
the chamber burning positive pressure, rumbling, smoke or other things that
indicate the waste loaded was too high a heat value and not able to burn
properly. The burners can be restarted after the waste calms down.
For future reference you may want to record all the SP settings on the FDC’s, ask your Dealer
to show you. (Note that some models do not use all the settings in their operation.)
