6�3 Change Fine Filter; 6�4 Self-Diagnosis - Renfert SILENT powerCAM EC Traducción Del Manual De Instrucciones Original

⇒ Insert a new waste bag through the holder and fold the ends over the holder
ring�
⇒ Place the waste bag with the holder into the dust drawer� The holder ring is
fixed in place in the dust drawer with magnets. Ensure that the waste bag:
- has contact with the side walls of the dust drawer;
- does not have contact with the seal surface�
⇒ Replace the dust drawer and slide in completely�
⇒ Close the fastening (4A)�
⇒ Press the enter key (25) (the time interval counter is re-set)�
♦ An audible signal confirms the drawer has been replaced.
♦ The dust drawer display (24) goes off�
If the dust drawer is not emptied, the dust drawer display (24) remains on.
After switching the unit off and on again, a 3 x audible signal indicates that
the dust drawer must be emptied.
In case of heavvy materials (for ex. zirconium dust) we recommend to use 2 waste bags for a safe
removal and a safe transport (bag in bag solution).
Only use original Renfert waste bags (see accessories).
6.3 Change Fine Filter
By monitoring the flow velocity (internal press key), it is possible to check the efficiency of the filter clean-
ing function�
If filter cleaning is required several times in succession after less than two hours, this means that the fine
filter is so heavily fogged up that the filter cleaning does not display any sufficient effect and the fine filter
needs to be changed�
This is displayed as follows:
♦ The error message lights up (26, Fig� 2)�
♦ 15 minutes long, acoustic signal 2 x, every 3 minutes�
♦ Output of the message in the CAM interface (see chapter 9�2)�
The error message can be removed by switching off the suction unit�
If a change of the fine filter is requested or the extraction force does not substantially improve
or only improves for a short time in spite of repeated cleaning, the fine filter must be changed
straight away.
Further operation may cause damage to the unit.
When the new fine filter is inserted, check that it is fitted correctly as otherwise leaks may occur. See the
assembly instruction at the end of the instruction manual, which is also attached to the new fine filter.
6.4 Self-diagnosis
The self-diagnosis helps the control system to check the function of the turbine and electronic parts�
If no fault is detected, the suction is ready for operation after the self-diagnosis has finished. If an error is
detected, this is indicated with a signal�
