Click on “Communication test”-“Digital outputs”, on the 9th button counting from the left,
to energize the coil cooling valve (11/V8), or start analysis cycle.
- Turn the restrictor (12) counter clockwise until the pressure on the gauge (13) is reduced
by about 0.2 to 0.3 bar (3 to 4 psi) when the coil cooling valve (11/V8) is open.
- Fix the locknut of the restrictor (12).
REMARK:
In case of using valuable gas for operating the pneumatics, the restrictor (12) should be
adjusted for lower flow by turning it clockwise. It can even be completely closed by turning it
clockwise up to the end of its range.
The flow adjusted with this restrictor is for cooling the combustion coil to ensure very long
service life.
According to our experience, the combustion coils of our analyzers don’t need
replacement, even after years of operation.
Check the following :
–
Open the furnace ( piston down ).
–
Hold the piston down by pressing on the horizontal bar of the furnace. ( with the fingers)
–
Press the key to close the furnace.
–
Allow the piston to go up very slowly by controlling the force of your fingers.
If not possible do the pneumatics adjustment, see pages before.
–
About 5 mm before the piston reaches its highest position the force will increase.
–
With your fingers press down firmly to make sure that the piston can not be pushed
down.
–
If the piston starts vibrating by moving up and down with full force, then adjust the switch
higher.
–
If the piston goes down, then adjust the switch lower.
