IDDX Flame Detector Amplifier Manual
IDD Analog Output Low and High Points
The analog output value corresponds to the average of the last five instantaneous counts of signal
intensity.
The IDD ANALOG OUTS screen shows the programmed values for the IDD analog output low and high
points. Plus, it displays the pick-up and dropout points that were just programmed in the last section for
reference. The Analog Output HI and LO will set the 0-10V and 4-20mA outputs and can be set to yield
the most information to almost nothing more than ON/OFF. To convey the most information, set the HI
to the actual high displayed on the IDD Signal screen and the low to a value lower than the dropout (DO)
value, which would be 1100 & 300.
To change the programmed values for IDD Analog Outputs on the Termiflex/SmartDisplay:
Press F1 - HI – type in “1100”
F4 - OK
F2 - LO - type in “300”
F4 - OK
F4 – NXT
Note:
The 4-20 output is not to be considered a calibrated output, to this end the output scale from the
factory is set at a default value of 3000 well beyond the usable range. In order to acquire a reasonably
linear output for display purposes, after the amplifier is properly set up and tested for proper flame
discrimination adjust these ranges as described above.
