Pneumatics adjusting for correct furnace movement:
When closing the furnace, the piston moves.
Open the right side panel of the analyzer to find the pneumatic valves (9 / V7), (10 / V10) and
(11 / V8) as well as the pressure regulator (8).
-
Turn the restrictor (12) clockwise up to the end for complete restriction.
-
Check the pressure on gauge (13) to be between 4-6 bar (60-85psi).
-
Press F2 to open the furnace.
-
Pull to unlock and then rotate the knob of the pressure regulator (8) counter clockwise for
minimum pressure (zero pressure).
-
Turn the screw (5) counter clockwise until the magnetic switch support (4) is free to move
up and down on the cylinder (6).
-
Shift the magnetic switch upwards up to the end of its adjusting range.
-
Press F2 for closing the furnace. The furnace closing cone (1) won’t yet move or move
very slowly.
-
Turn clockwise the knob of the pressure regulator (8) until the closing cone (1) can rise
smoothly (without shaking) up to the upper end of its stroke. To do this, open and close
the furnace (F2) as often as needed. Take software delays into account.
-
The pressure should be only as high as necessary and low enough for a person to be
able to stop by hand the cone from rising.
-
Push the knob to lock the pressure regulator (8).
-
When the furnace is closed, slowly shift the magnetic switch (3) with its support (4)
downwards until it just switches on. This can be recognized due to the clicking of a
pneumatic valve (10/V10) and the piston moving then slightly higher.
-
Make a marking on the cylinder (6) at the upper end of the magnetic switch holder (4).
-
Shift the switch with holder downwards until the magnetic switch is off (A valve clicks and
the piston slightly moves downwards).
-
Make a second marking on the cylinder (6) at the upper end of the switch holder (4).
-
Adjust the switch holder (4) to have the upper end in the middle of the two markings.
-
Open the furnace and then close it again (F2) to verify the correctness of the adjustment.
-
Adjust the lower cushioning (7), so that the furnace opens without the piston banging at
the bottom.
