Page 35: Example Sequence
AUR890 stops showing the sequence code [- -]. * The AUR890 turns the main valve ON after the standby process for normal combustion. This feature does not allow the main valve to be turned on immediately after ignition in order to prevent the flame from being blown out. During the standby process for normal combustion, if the time set for external timer TM1 has passed and the contacts are reversed, the supply of power to the pilot valve and main valve may be interrupted for a moment. -

Page 43: Chapter 5. Trial Operation And Adjustment
Chapter 5. Trial Operation and Adjustment WARNING Make sure that the ignition times for the pilot and main burners do not exceed the ignition times specified by the burner or device manufacturer. Excessive ignition times may cause fuel to accumulate in the combustion chamber and form an explosive fuel-air mixture, which can result in a serious explosion hazard. -
Page 44: Ignition Spark Response (Uv Sensor)
Chapter 5. Trial Operation and Adjustment „ Ignition spark response (UV sensor) WARNING Ensure that the UV sensor does not detect ultraviolet rays other than those from the burner. If the UV sensor responds to other ultraviolet radiation, fuel will continue to be supplied even if the burner flame is off, potentially causing an explosion. -
Page 45: Measurement Of Flame Voltage
Chapter 5. Trial Operation and Adjustment „ Measurement of flame voltage This device shows the flame voltage on the 7-segment display. It can be checked by changing the display using the DISP switch on the front of the device. Checking the flame voltage is the best way to determine whether or not the location of the flame detector is appropriate. It should be checked during installation and servicing. Checking it once per month or more can prevent shutdowns due to insufficient flame voltage. -
Page 46: Measurement Method For Flame Voltage
The voltage can be checked on the 7-segment display or by connecting a flame meter to terminals 25 and 26 of the front connector. Analog ame meter Flame voltage display FSP136A100 * Connector for front wiring (81447514-001/002) is required to connect FSP136A100 to AUR890. Handling Precautions • For flame voltage output signal wires, use wire with indoor PVC insulation ("IV wire," JIS C3307) 0.75 mm . Wiring length cannot be more than 10 m. • The input impedance of a measuring instrument used with this device must be 100 kΩ or more. -
Page 47: Pilot Turn-Down Test
Chapter 5. Trial Operation and Adjustment „ Pilot turn-down test WARNING Make sure that the pilot turn-down test is done properly. If the flame detector is able to detect a pilot flame that is too small to ignite the main burner, and if there is a flame failure of the main burner, this device will not be able to recognize the flame failure. -
Page 48: Safety Shutoff Check
Chapter 5. Trial Operation and Adjustment Handling Precautions • If it is necessary to repeat the test, each time it is repeated be sure to stop all the equipment first to prevent an explosion and then discharge all unburned gas that has accumulated in the combustion chamber and exhaust flue. (6) Change the gas pressure from the minimum to the maximum and repeat steps (1) to (5) to check if the main burner ignites properly. -
