4.5 Connection to a CAM interface
Only ever use the CAM interface which is provided for remote control of
the extraction unit.
For CAM systems which only provide a switched mains voltage, it is
essential to use "interface cable type F".
If the suction is frequently switched on or off via the CAM power supply,
it may cause electronic damage to the CAM system as well as to the
Silent compactCAM.
The electrical connection for communication with the CAM device is provided
by the interface socket (8) and an optional interface cable (see accessories)�
For information on interface cables available for the CAM device or producing
an individual interface cable see chapter 9�1 CAM interface�
Check with your CAM manufacturer, that the interface for the connection
of the extraction is energy limited according to the IEC 61010-1.
Please also see the CAM device instructions for use�
4.6 External Exhaust Air Route
An external exhaust air route (see accessories) allows the extracted air to leave the laboratory�
The installation details are supplied with the external exhaust air route�
When the extraction unit is used in conjunction with an external ventilation system, a significant
quantity of air is extracted from the room per hour. This can create negative pressure within the
room which, when using an air dependent naked flame fed by gas, liquid or solid fuel, can cause
poisonous gasses (e.g. carbon monoxide) to be drawn into the working area.
It is therefore essential to ensure that the fresh air supply is sufficient and that the environmental
air pressure is maintained, this should then be monitored by an authorized specialist (e.g. a certi-
fied Gas Service Engineer).

Operation

The extractor unit is operated via the buttons on the key-pad (Fig� 2)�
5.1 Switching the Unit On
The extractor is switched ON and OFF at the On / Off switch (3)�
When the unit is switched on:
♦ The suction unit performs an automatic filter cleaning sequence (for approx.
8 seconds, loud vibrating noise) (see chapter 5�4)�
Then the unit returns to the last set operating mode�
5.2 Select Mode: CAM-mode / Continuous Operation
The extraction unit has two operating modes�
The set operating mode is shown in the display (20) / (22)�
• CAM-mode (20):
The extraction unit is controlled by the signals provided by the CAM device�
The control signals can be used to:
- trigger filter cleaning;
- extract with suction level 1 *);
- extract with suction level 2;
- stop the suction turbine�
(see chapter 9�2)
• Continuous operation (22):
The extraction unit runs continuously�
⇒ Press the operating mode key (21)�
♦ To change the operating mode�
*) Suction at different suction levels is only possible if the CAM system supports this�
In CAM systems, which only have an ON/OFF signal for activation, the suction will always function at level 2�
The extraction unit is for use with dry dust only!
When connected to a CAM device with wet and dry function, ensure that no residual moisture
from the CAM device enters the extraction unit.
Check that the extraction unit is in full working order for every milling procedure:
► Display error (26, Fig. 2) is off.
► Suction turbine operates correctly without producing any peculiar noise or odor.
