Media to the chamber
Before media can be admitted to the chamber, all the requirements
below must be met:
A Emergency stop not activated
B Door(s) closed.
C Door seal pressurized.
D Control system giving a control signal to open the media valves.
Checking the door action
The speed of motion of the door can be changed with the variable
restrictor in the air line to the door cylinder. Changing the closing speed
has an equal effect on the opening speed.
1. Check that the door closes in 10-15 seconds. Adjust the restrictor if
necessary (see pipework diagram).
2. Check that the motion is even and smooth.
3. Check that the door does not scrape against anything during its
motion. Adjustment advice is given under “Adjusting the door
position”.
Checking and adjusting the door position
A. VERTICALLY
This adjustment may be necessary of the 3 mm dimension between the
top edge of the door and the bottom of the chamber is not maintained,
or if the door does not fully cover the seal groove.
1. Measure the door adjustment required.
2. Open the front.
3. Raise the door by activating its pilot valve by hand.
Always disconnect the compressed air supply before
removing to door or adjusting its position. This ensures
that the door does not move accidentally.
