Chapter 5. Trial Operation and Adjustment
• Incorrect flame detector mounting angle (AUR355C)
• Dirty flame detector sensing surface (AUR355C)
• Tube unit deterioration (AUR355C)
• Incorrect flame rod installation (AUR355B)
• Area in contact with flame is insufficient.
• Position of flame rod in flame is incorrect.
• The flame rod insulator is at a high temperature (315°C).
• Flame rod is affected by the ignition transformer.
If the ignition transformer is close to terminal F of the flame rod, electrons
in the flame will be absorbed into the ignition transformer, and as a result,
sufficient flame voltage will not be achieved.
The voltage can be checked on the 7-segment display or by connecting a flame
meter to terminals 25 & 26 on the front connector. It is necessary to obtain a
monitor/communication connector (81447514-001) to connect the FSP136A100
and the AUR355.

Handling Precautions
• For the flame voltage output signal wires, use 600 V PVC-insulated cable (IEC
60227-3), 0.75 mm
2
or more in cross-sectional area. The wiring should be no
longer than 10 m.
• The input impedance of a measuring instrument used with this device must
be 100 kΩ or more.
