Fig. 22: Fig. 33: Valves
After pressing the key to open the furnace, the valves (V1) and (V2) are energized.
This means that they have across their coils 24V DC coming from the electronic
unit.
Valve (V2) closes the oxygen supply to the furnace.
Valve (V1) opens, releasing the pressure from the furnace through the dust trap
(3), through the moisture trap (4) and through the filter cartridge (1) into the open
air (in the direction of the arrow).
Following this, the pneumatic valve shuts and the furnace opens (lift downwards).
When dust comes out of the furnace after this process this will cause, that the
pressure in the furnace is not sufficiently reduced.
The causes:
–
Too much dust in the dust trap (3),
(a few hundred analyses without cleaning)
–
Saturated moisture trap (4)
–
Clogged paper filter in the moisture trap (4)
–
Clogged filter cartridge (1 and 2) (this would be unlikely though)
–
One of the valves (V1) or (V2) receives no power (24V DC)
NOTE
The valve (V1) will only be supplied with voltage (24V DC) until the lift has reached
the bottom position, then it will be switched off.
The 24V on the coil of this valve can be measured with a digital voltmeter, or with a
light bulb of 24V / 20mA.
One of the valves (V1) or (V2) is jumps, most likely valve (V1)
•
Clean the valves.
