Little or no compressed air pressure, the furnace cannot close.
This pressure is shown on gauge (13), on the front-side of the analyzer.
It must be between 4 to 6 bar (60 to 90psi).
The screw (2) must be turned counter-clockwise, as much as possible.
Adjust regulator (8), so that the furnace floor can rise completely, without shaking;
while a person still can stop the moving furnace floor with only one hand.
This is a safety precaution.
Repeat above instruction, until the adjustment is completed. Now, the upward
speed is fast enough, yet safe for the operator. The pressure regulator (8) is found
on the inside, on the right-side section of the analyzer, installed on the rear panel.
One of the pneumatic valves (V7) or (V10) (or both) is malfunctioning.
The magnetic coil of the pneumatic valve (V7) or (V10) is not powered. The
furnace floor goes up, when valve (V10) receives 24 VDC.
The 24 V DC comes from the microcontroller board; if not, replace the electronic
drivers.
