FFRT Set-Up Description
Using the keypad the scanner flame failure response time can be set by the user to the desired timing.
Each unit comes from the factory preset at 1 second. To change the factory default to a different
FFRT see Set-Up Procedure below. To verify the current FFRT setting, press and hold the UP push
button with the scanner in the normal operating mode. The “flame strength” LED set will display 1st,
2nd, 3rd or 4th LED as appropriate and these correspond to the FFRT in seconds.

Press UP or DOWN push buttons to select required FFRT (the selected FFRT is displayed on the flame
strength LEDs as either 1st, 2nd, 3rd or 4th). Once you have selected the correct value, Press both the
Target Flame Select and Background Flame Select buttons simultaneously to store. The stored value
can be displayed and checked at any time while in the normal run mode. Pressing and holding the UP
