● Slide the placement head by hand over the board conveyor (see CAUTION note in Section 7.2 ’Fault Char-
acteristics’).
● Release the clamping lever and lift and using a lift truck move the components changeover table including
fitted feeder modules carefully out of the machine as described in the User Manual.
● Make sure that the mains plug of the components table is pulled out!
● Unscrew and remove the fuse F1 at the transformer T1 (see Fig. 7.3.1).
– If the fuse is defective, first, where possible, remove the cause of the problem, which should be looked
for on the output side of the transformer:
If necessary, remove the communications unit (see Section 7.5) and use the meter at the 5-pin plug
(cable of power supply communications unit) to see whether there is a short circuit in the cable or in
the transformer winding. Please note the following NOTE!
– If you can correct short circuit in another way, replace the fuse, rating 3,16 AT.
NOTE
The transformer T1 and / or the cables Y558-W1 and Y545-W1 at the transformer (see Fig. 7.3.1) will be
replaced only by the SMD Service department of Siemens AG.
● Install the components changeover table back in the machine in the reverse sequence of operations to
removal as described above. Make sure the plug connections (mains plug and X37, and, if applicable,
pneumatic connection) are firmly seated.
● Switch the machine on and start the placement sequence.
