Safety Precautions
WARNING
Do not use this unit with a burner controller that is not made by Azbil
Corporation.
Make sure that this device does not detect ultraviolet rays other than those of
the burner flame. If it responds to other ultraviolet radiation, flame failure in the
burner will not be detected.
As a result, the outflow of fuel will continue, causing a very serious explosion hazard.
Before removing, mounting, or wiring this device, be sure to turn off the power to
the device and all connected devices. Failure to do so may cause electric shock.
Before doing any wiring work, be sure to disconnect the power to prevent elec-
trical shock.
To prevent explosion, carry out the pilot turndown test carefully. If this device
detects a pilot flame that is too small to ignite the main burner, the burner con-
troller will not be able to recognize flame failure of the main burner, allowing
the outflo
w of fuel to continue, leading to a serious explosion hazard.
If the pilot turndown test is carried out repeatedly, completely shut down all
equipment each time the test is finished, and completely discharge unburned
gas or fuel that has accumulated in the combustion chamber and flue. If un
-
burned gas and oil are not discharged completely, an explosion may occur.
Do not touch terminals F or G on this device or on the burner controller imme-
diately after the power to the burner controller has been turned OFF. There is a
danger of elec
tric shock because terminals F and G retain a charge for up to 1
minute after the power has been turned off.
When measuring the voltage between terminal F and terminal G of this device in
order to check the wiring, do not touch any part of the terminals. Doing so may
result in an electric shock.
Do not use this device with the cover removed. Doing so may result in an electric
shock. If the cover has been removed from this device, be sure to reattach it and
tighten the four mounting screws completely before use.
CAUTION
This device is designed for both batch operation of the burner (at least one start
and stop in a 24-hour period) and continuous operation (nonstop combustion
for 24h or longer). It must be used with a burner controller having a dynamic
self-checking function.
Mounting, wiring, inspection, adjustment, maintenance etc., should be carried
out by a trained and experienced technician with knowledge and technical skills
related to combustion equipment and flame safeguard control devices.
