5. Operation
5.1 Start Operation
WARNING
Confirm the air is supplied before starting operation.
Confirm that the ventilation system is running before introducing the gas.
n
Introduction of the Sample Gas
l
For town gas use
1) Open V-1 fully.
2) When the pump is attached, turn ON the power supply before proceeding to (3).
3) When the pressure is increased by the pump, adjust the pressure by V-5 so that the
pressure gauge (3-2) indicates 8 to 18 kPa. When the pressure is reduced by the pressure
reducing valve, adjust the pressure by the pressure reducing valve (3-8) so that the
pressure gauge (3-2) indicates 8 to 18 kPa, .
l
For steel mill use.
1) When you use the standard pressure, open V-4. When the pressure is increased by the
pump, open V-1, V-4 respectively.
2) When the pump is attached, turn on the power supply switch of the pump at this time.
3) Use V-3 for standard pressure or use V-2 and V-3 for the pressure raised by pump to make
the pressure gauge indicate approx. 6kPa.
n
Start Operation of the Calorie Detector
Confirm the switch “SAFE EV” is set at “SET” then push the switch “START”.
n
Differential Pressure Readjustment
When the burner is ignited and the output becomes stable (after 20 to 30 min.), adjust again the
differential pressure.
l
For town gas use
1) When the pressure gauge (3-5) does not indicate approx. 3 kPa, adjust the pressure by the
pressure reducing valve (3-4).
2) When the density meter is attached and the flowmeter (5-3) indicates out of 0.5 to 1 l/min,
adjust its indication again.
3) Set the computing station to Input / Output status display. If the indication of “X2 (A-PRESS)”
and “X3 (G-PRESS)” is not ”500”, adjust each with the pressure reducing valve (3-6) and
V-16.
