CONTROL PANEL FUNCTIONS
Fig. 11
1 Mammomat 3000 Nova ON/OFF
2 Exposure release buttons with green lights. Both buttons must be pressed during the entire exposure. This is
to ensure that the operator is standing behind the radiation shield during the exposure.
3 +/- kV selection and display
4 +/- mAs selection and display. In AEC mode (Automatic Exposure Control), the display remains dark before
exposure. After the exposure, the mAs value reached during radiography is indicated.
5 +/- film density adjustment and display.
6 AEC. These buttons are used to activate AEC mode (Automatic Exposure Control) and to select screen/film
system. H stands for high speed and D for detail screens.
7 Buttons for selection of anode/filter combination in manual mode.**
8 Buttons for selection of one of four pre-programmed exposure parameter settings.*
9 Button for storing exposure parameter (see 8).*
10 Button to select/deselect auto mode.*
11 Button to select/deselect automatic decompression after exposure. When off, use foot switch or the knobs for
manual decompression.
12 Limit button (acknowledgement). Serves to reset the system after errors, indicated by an error code, or faulty
exposures (limit errors), indicated also by the limit lamp and acoustic signal (e.g limit mAs, dose monitoring,
interrupted exposure).
13 Limit lamp. Flashing: Tube temperature is above normal. Lit: Limit error (see 12).
14 Cassette is missing or needs to be replaced (it has already been exposed).
15 Object table or object table arm is not locked in position.
16 Risk of collision between tube head and floor (limit switch is actuated).

17 AEC detector not in chest wall position (only in stereotactic mode).
18 Diaphragm not in correct position. In stereotactic mode: External diaphragm not in position.
19 Focal spot indication. Indicates focus in operation. Small focus is automatically selected, when a magnifica-
tion table is used.
20 Green light indicates that the unit is ready for exposure. This indicator has the same function as the green
