MAMMOMAT compression unit 1

Calibration after an exchange (replacement) 1

General Remarks 1

The mechanical work not described here includes the removal of the swivel arm covers, the disconnection of the connectors X 872, X 873 and X874, and the removal of the bolts holding the compression unit in its place (there are three such bolts in MAMMOMAT 3000/ 3000 Nova, but in MAMMOMAT 1000 there are four of those bolts holding it). This work can be done basically without an additional written instruction.

It is important, however, that the newly installed compression unit be fixed within the possibilities given by the tolerances of the holes in such a manner that the front edge of the compression plates is parallel with the breast-wall edge (thoracic edge) of the object table.

At the same time one should comply with the adjustment procedure as is described in the corresponding Chapter 3 of the currently valid instructions "Replacement of parts - Compression plates", Print no: SPB7-230.841.01. The adhesive gauge block mentioned there has the material number 6483775.

NOTE

When positioning the exchange (replacement) compression unit to its place, especially at the MAMMOMAT 3000/3000Nova, make sure that the two little isolating shrunk-on hoses fixed on the backside of the electromotor do not get entangled in the upper part of the arc (or dome, also called "church"). The electromotor has to move freely under that arc. Several checks moving it by hand are necessary! See attached pictures.
