1.6 Safety information and preventive measures
NOTE •When completing repair work and tests, please note:
- the product-specific safety information in the document,
- the safety information in TD00-000.860.01... ,
•When the system is switched off via the operating panel or
S2/D711, line voltage is still present at the line voltage connec-
tion for the generator, at line voltage filter Z1, at transformer T1,
at transformer T10, and on board D711 (refer to circuit dia-
gram).
•After switching off the system, approximately 380 V DC may be
present in the intermediate circuit as indicated by the V24 LED
on board D710. Within 3 minutes, the voltage will drop to less
than 30 V, and the LED will go out.
•Tests or adjustments that must be made with the radiation
switched on are identified by the radiation warning symbol.
During these types of adjustments, radiation protective cloth-
ing must be worn.

2.1 Checks
Fig. 1: MAMMOMAT checks
PMP Radiation protection
•Check the radiation protection shield for possible damage (1/Fig.1/p.13).
•Information regarding the lead equivalent value must be legible.
SIM Swivel arm/PPS tube attachment
•Check the swivel arm/PPS tube attachment by pulling on both support rails
(a minimum play of approximately ± 2° is correct). (2/Fig.1/p.13).
SIM Basic table
•Check the mounting of the basic table as well as the locking mechanism for the expo-
sure system (3/Fig.1/p.13).
SIM Flying wing (MAMMOMAT 3000 Nova only)
•Check the "Flying Wing" locking mechanism (wing basic table). Swivel "wing 1"
("wing 1" is the table with the stereo connector) toward "wing 2" and back
(6/Fig.1/p.13).
SIM Level
•Verify that the system is level with respect to the floor. Check the level screws
(4/Fig.1/p.13)with a water level and, if available, the floor mounting (optional).

3.1 Checks
SIM Steel ropes
•Do the steel ropes (balancing and flap), the drive belt, the suspension, or the pulleys
have any damage (e.g. fraying or splitting) or show signs of wear?
PMA Oil and grease
•If they are OK, lightly oil the wire cable, grease the rails, and then remove the protective
strips.
SIE Limit switches
•System ON. Move the lifting carriage up and down several times, the lifting carriage
should be in an upright (0°) position.
NOTE It is normal to hear some noise from the rotation of the radiation
filter in the collimator when switching the system ON.
•Do the limit switches stop carriage travel at the top and at the bottom?
•Activate safety switch S882. System movements must be blocked.
PMF Vertical travel
•Is the vertical travel smooth and noiseless?
•Switch OFF the system and attach the protective strips once again.
SIM Safety catch and rotation safety catch
•Do the safety catch (1/Fig.1/p.17)and rotation safety catch (2/Fig.1/p.17)have any
visible damage? Are the springs in good condition?

SIM Ball bearings
•Depending on the serial no. of the MAMMOMAT, the lifting carriage is equipped with ei-
ther ten or twelve ball bearings (refer to (Fig.2/p.18)). The two ball bearings that are
missing in MAMMOMATs with ten bearings are only indicated in the figure. Check that
all ball bearings are in place and that they show no sign of damage.

4.1 Testing the "Compression" function
Fig. 1: Compression
•Attach the spring scale as shown in (1/Fig.1/p.20)and be careful not to damage the
compression plate during the following tests: Tolerance: ±1 kp.
4.1.1 Switching off
•System ON
PMF Presetting
•Select any value (e.g. 6 kp) on the potentiometer (2/Fig.1/p.20)and compress. Does
the compression unit switch off at this setting?
SIE Max. value switch off
•Select the maximum value (20 kp) with the potentiometer (2/Fig.1/p.20). (20 kp).
Does the unit switch off when it reaches the maximum value?
•Correct display (7/Fig.1/p.13).
PMF OPCOMP
•Position your forearm between the object table and the compression plate and check
the OPCOMP function.
¹Typically, the cutoff value is between 6 and 10 kp at the factory setting.
