Frequency of maintenance and inspection
Determine an inspection cycle taking into consideration the following factors:
• Type of equipment
• Ambient conditions of installation site (dust, temperature, etc.)
• The effect of burner failure on equipment operation.
(1) Carry out the safety shutoff test described in
Chapter 3, ADJUSTMENTS
FOR TRIAL OPERATION
at least once a month.
(2) Measure the flame voltage at least once a month.
(3) Check the viewing window on the
AUD100
series advanced ultraviolet flame
detector, the flame rod, etc. for dirt, and clean as necessary.
(4) Check the ambient temperature.
(5) If equipment will be seriously damaged by a burner failure, carry out this
inspection more frequently.
WARNING
Before removing, mounting, or wiring the FRS100, be sure to turn off the
power to the FRS100 and all connected devices. Failure to do so might cause
electric shock.
Even after the power to this device is turned off, terminal F continues to hold
an electrical charge. To avoid electrical shock, do not touch terminal F.
To prevent electric shock, turn the power off and discharge terminals F and G
before removing this device from the subbase. Use lead wires to connect
terminals F and G of the flame simulator (FSP300C100) to terminals F and G
of this device for 10 seconds or more.
CAUTION
Installation, wiring, inspection, adjustment, etc. should be carried out by a
trained and experienced technician who has knowledge and technical skills
related to combustion equipment and flame safeguard control devices.
Conduct periodic inspections in accordance with the user's manual of the
equipment manufacturer.
If the safety shutoff has been activated, check all of the items on the check-
lists in Chapter 3, ADJUSTMENTS FOR TRIAL OPERATION before
restarting the equipment.
When doing a maintenance inspection of the burner, be sure to do the pilot
turndown test. Inspection must be done at least once a year.
When cleaning the burner, clean the flame detector as well.
This device has an operating life. Assuming that the operating life of the
combustion equipment used with this device is longer, be sure to do periodic
maintenance and replacement of this device.
In the event that this device is replaced, do all of the checks listed in Chapter
3, ADJUSTMENTS FOR TRIAL OPERATION.
