CAUTION
Follow all applicable regulations when doing the wiring work.
Connect the blue signal lead from the AUD100 series Advanced
Ultraviolet Flame Detector to terminal 5 and the white lead to terminal
6. Turning on the power when the flame detector is incorrectly wired
could damage the AUD15C tube unit.
Run the high-voltage ignition transformer cable separately and keep it
at least 10 cm away from this device.
Make sure that ignition transformer high-voltage cables are properly
connected to prevent faulty contact. Faulty contact might generate
high-frequency radio waves which can cause malfunction.
The ignition transformer ground lead should be connected directly to
the burner body or to a metallic part electrically connected to the
burner body.
Keep power lines and ignition transformer high-voltage cables
separate from the flame detector wires.
Always supply electric power at the voltage and frequency stated on
the model label of this device.
Always connect the power supply last. Otherwise, touching a terminal
accidentally could result in electric shock or damage.
In keeping with technical standards for electrical equipment, the burner
body must have an earth ground connection with a resistance of less
than 100
Ω
.
After the wiring is complete, be sure to check that it is correct.
Incorrect wiring may cause damage or faulty operation.
Make sure that the flame detector does not detect the ignition spark. If
the flame detector can detect the spark, change the detector's line of
sight or change the ignition electrode's position.
Only an experienced technician who has knowledge and technical
skills related to combustion equipment and combustion safety should
carry out the pilot turndown test.
This product is equipped with functions that are extremely important
for the safe operation of combustion equipment. Carefully follow the
instructions for its use that are given in this user's manual.
