Section 9). Correction: Replace cutter blade and cutter wheel; after this, pretension the cutter wheel
(see Section 7.6 ’Empty Tape Cutting Unit and Empty Tape Channel’).
– The pretensioning of the cutter wheel is inadequate which means the tape is not being cut.
– The pressure rod is not swinging in far enough: the tension springs are fatigued or have detached.
– The setting of the swivel movement is incorrect: see Section 7.6 ’Empty Tape Cutting Unit and Empty
Tape Channel’.
● At cycling on, the tapes will not move; or the tape pressure rod does not swing away
Possible causes:
– The 5.6 bar compressed air branch (= operating pressure) from the compressed air unit to the tape
cutting unit is leaky or the compressed air hose is pinched.
– The compressed air cylinder is defective: replace.
– The solenoid valve at the tape cutting unit is not being actuated; there is a break the cable (plugs X3ak
→ solenoid valve); the solenoid valve is defective; there is a fault in the communications unit.
– The swivelling movement of the pressure rod is being restricted by a mechanical obstacle or it has
been adjusted incorrectly: (see Section 7.6.12.4 ’Adjusting the Swivel Movement, Replacing the Ten-
sion Springs’).
● Individual tapes are not being cut or are backing up in the empty tape channel
Possible causes:
– The fins in the empty tape channel are bent or are no longer touching the outer guide plate an: replace
and adjust the "inner guide plate" or the complete empty tape channel.
– The tapes of the outer tracks (1 and/or 120) are not being cut:
– The switching point of the corresponding limit switch has been set incorrectly (the cutting stroke
should be 656 mm; see Section 7.6 ’Empty Tape Cutting Unit and Empty Tape Channel’).
– Only the tapes of the first tracks (from 1 upwards) are not being cut correctly:
– The pressure rod is swinging in too slowly or bounces: adjust the exhaust air restrictor at the sole-
noid valve (see Section 7.6.15 ’Concluding Work’).
– The empty tape channel was not aligned symmetrically with the pressure rod when it was refitted.
7.2.1.2 Fault in the Vibrator Activation
● An individual vibratory feeder (vibrator) in the activated conveyor sector/location (1; 3) is failing to
convey components
Possible causes:
– The vibratory feeder will not activate (Check: "Refill track" → select linear feeder): electrical interrup-
tion in the vibratory feeder or in the power supply cable; poor contact in the plug connection at the
connections panel.
– Interruption in the 24 VAC supply voltage at the corresponding connection socket (LED on the connec-
tions panel illuminates) or the vibrator controller of the communications unit: check the plug connec-
tions ; if necessary, replace the communications unit.
– The period of time for vibrator activation has been input incorrectly (see User Manual for the UNIX line
computer, Section 5, under "Coordinates Correction").
– The vibration intensity has not been set correctly at the potentiometer rotary button (on the connec-
tions panel of the communications unit): see Section 7.2.1.2 ’Fault in the Vibrator Activation’.
– The basic calibration of the vibratory feeder needs readjusting.

– 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".
