2.9.2 Safety Precautions for Closing Hoods and Process Cham-
ber
In order to eliminate any risk of injury when closing the oven’s hoods and
process chambers, the operating company must require oven operating per-
sonnel to close the hoods and process chambers in accordance with the fol-
lowing instructions only.
During the closing of hoods and process chambers there is a danger of per-
sons’ limbs being jammed in the gap between process chamber cover and
bottom or between hood and frame.
When closing hoods and process chambers the horn sounds as an addition-
al indication of a danger situation.
Description:
• Make sure that nobody is in close proximity to the hoods or process cham-
ber when they are opened and closed.
• For opening or closing press the software button in the main mask.
• Keep the software button pressed until the hoods or the process cham-
bers have been opened or closed completely. If the button is not pressed
any more the hoods or the process chamber stay in the present position.
Danger!
If Hoods and Process Chambers are Closed Incorrectly.
If during opening or closing of the process chamber a failure of the drive
motor occurs (power failure, motor protection tripped), the process cham-
ber remains in its momentary position. Only after rectifying the failure, the
process chamber can be moved into the desired position by means of the
software button.
