Safety Precautions
WARNING
Before mounting, removing, or wiring, be sure to turn off the power to this device and all
connected devices. Failure to do so may result in an electric shock.
This device has functions that are extremely important for the safe operation of combustion
equipment. Use it correctly in accordance with the user’s manual.
This device does not have a prepurge and sequence function. Use this device as part of
a system whose design gives careful consideration to the function established safety
guidelines. If the combustion chamber and gas flue are not ventilated to remove any
unburned gas, the ignition process may cause an explosion.
Make sure that the AUD flame sensor does not detect UV rays from a source other than the
burner.
Do not touch terminal 14 (F) after turning the power off. An electric charge may remain on
terminal 14 (F) and may cause an electric shock.
Carry out the pilot turn-down test carefully. If the flame detector is set so that it detects a
pilot flame that is too small to ignite the main burner, this device will not be able to detect
a flame failure in the main burner. In that case, fuel will continue to be supplied, causing a
serious explosion hazard.
Do not use the event output or alarm output as safety output.
This device has a limited product life. Replace this device within its product life. Beyond the
product life, the risk of device failure becomes higher.
Do not disassemble this device. Doing so may cause malfunction, device failure, or electric
shock.
Do not operate this device without first completing its adjustment and testing, and also the
testing specified by the combustion equipment manufacturer.
Never short-circuit the start contact in order to start and stop this device by switching the
power on and off. This is very important for reliable activation of the self-check circuit at
device startup. Failure to observe this warning could lead to an explosion.
Before doing the pilot turn-down test or ignition spark response test, make sure that all
manual fuel valves are closed.
If the pilot turn-down test must be carried out repeatedly, completely stop all combustion
equipment each time the test is finished, and completely discharge unburned gas or fuel oil
that has accumulated in the combustion chamber, ducts, and flues. Otherwise, an explosion
may result.
After completing the pilot turn-down test, turn off the power switch. Restore the original
state of all test jumpers and limit switches and reset the controller settings. If operation
begins without the above steps, damage to the equipment, gas leak, or explosion may result.
Close the fuel valve before using the flame simulator for a check while this device is attached.
If you use the flame simulator during normal operation, since a flame will seem to be present,
fuel will continue to be supplied even if the pilot burner or main burner is off, possibly
causing an explosion.
