CAUTION
The AUD300C is specially designed for intermittent burner operation (system is started and stopped
once or more within 24 hours) and 24-hour continuous burner operation (combustion continues
for 24 hours or longer). It must be used with a burner controller having a dynamic self-checking
function.
Only authorized personnel who have the technical skill about the combustion equipment and flame
safeguard control must carry out the mounting, wiring, inspection, adjustment, and maintenance
work.
If this unit is operated in an atmosphere where any steam, smoke, oil mist, dust, and/or organic
solvent exist that hinder the penetration of ultraviolet rays, take appropriate corrective measures.
When using multiple burners, mount this unit at a position where it detects the flame of only the
burner to be monitored.
Carry out the wiring work in conformity with the specified standards.
Always separate the signal cables of this unit from the high voltage cables of the ignition transformer
and power cables, and then always run the signal cables in a different conduit tube.
After the wiring work has been completed, always check that the wiring is correct. Incorrect wiring
may cause damage or malfunction.
Only authorized personnel who have the technical skill about the combustion equipment and flame
safeguard control must carry out the pilot turndown test.
Do not transport this unit with it mounted on the combustion equipment. The impact or vibration
during transportation may cause this unit to malfunction.
Before starting the transportation, remove this unit and put it in the specially designed packing
box.
The service life of the tube unit and shutter unit components of the AUD300C is a maximum of 3
years. To ensure operational safety, be sure to replace them with new ones within this service life
period. For replacement, use the AUD Maintenance Kit (AUD60A1000), which includes the tube and
