There is no vibrator (= vibratory feeder) defined in this track: see User Manual for the UNIX line com-
puter, under "Conveyor Sector Editor".
The vibratory feeders of an entire conveyor sector or location (1; 3) are not being activated
Possible causes:
No vibratory feeders are defined at this location (see User Manual for the UNIX line computer, under
"Conveyor Sector Editor").
There is no voltage at the components table: the fuse on the input side of the transformer compo-
nents table is defective (leads to error message "Communication with table faulty"): see Section 7.3
’Components Table Power Supply’.
Defect in the vibrator control circuit; interruption within the communications unit: replace communica-
tions unit.
If the fault cannot be corrected despite these measures: SMD Service department of Siemens AG
should be notified.
7.2.1.3 Fault in the Components Table Pneumatic System or Components Table
Compressed Air Supply
An individual compressed air feeder module is not conveying:
Possible causes:
The feeder module has not been positioned correctly; the locking device at the end of the module has
not engaged and closed.
The associated pneumatic adapter in the components table compressed air supply is leaky: replace o-
rings, replace pressure spring see Section 7.7 ’Components Table Pneumatics, Components Table
Compressed Air Supply’.
The solenoid valves in the compressed air feeder module are not switching:
The compressed air feeder module has not been defined on this track (see User Manual for the
UNIX line computer, "Conveyor Sector Editor").
Solenoid valve(s) in the feeder module is (are) defective; electrical interruption in the module or in
the connecting cable of the module (see the Service Manual for the module).
Interruption within the communications unit: replace (see Section 7.5 ’Communications Unit’).
None of the compressed air supply modules of a location is being activated or conveying correctly
Possible causes
At this location (1; 3) no compressed air supply modules have been defined (see User Manual to the
UNIX line computer, under "Conveyor sectors").
Compressed air for the components table compressed air supply has not been set precisely to 5 bar:
for setting, see Section 7.7 ’Components Table Pneumatics, Components Table Compressed Air Sup-
ply’.
Pressure loss in the compressed air branch (5 bar) from the compressed air unit to the components
table compressed air supply.
Break in the components table interface cable (signal not arriving from the control unit). See also:
error message "Communication with table interrupted".

7.3 Components Table Power Supply
DANGER QQQ
Before you start work on the components table power supply, the components changeover table must be dis-
connected from the main power supply (main power plug, on the right-hand side of the machine base).
Please note, with all work in the machine base interior and in particular on the components table power supply
the stricter VDE 0113 safety regulations apply.
7.3.1 Tools and Spare Parts Required
Auxiliary Measuring and Test Equipment
Ohmmeter
Spare Parts
Miniature fuse 5x20/T3,16AT, from item no. 00304938-01
Cable for components table interface Y558-W1, from item no. 00300380-06
Cable for transformer power supply of components table Y545-W1, from item no. 00300379-03
NOTE:
With error message "Communication with table interrupted" the fuse F1 at transformer T1 could be defective.
Carry out preliminary fault location with the aid of Section 7.2 ’Fault Characteristics’.
Details of the components table power supply will be found in the Overview section, the corresponding circuit
diagrams in the current circuit diagrams folder: Plan 1710460-Y0928-...-L-.../ -Y0558-..-L-... / -Y0545-...-L-..
7.3.2 Replacing Fuse F1
Select "Abort placement" to return all picked-up components.
DANGER QQQ
Switch off the machine at the main switch and disconnect it from the main power supply.
Undo the plug connections of the components changeover table at the machine base on the right beside
the components changeover table (mains and interface connector X37 and if applicable the pneumatic
connection).
Open the protective covers and pull cover at the components loading point upwards and away.
