Error No. 388: "Checksum error in the table program"
The SMD Service department should be notified: the table program must be reinstalled.
Error No. 397: "Checksum error during communication with table"
Possible causes:
Transmission error: Select from within the machine errors menu "Continue".
Error No. 399: " Program loss of the table or trolley control"
Possible causes:
Back-up battery of the processor board (communications unit) must be replaced: See Section 7.5
’Communications Unit. Note: With a cold restart the components table is automatically loaded; how-
ever this can also be effected by means of the single function "Load table" reached .
Error No. 400: RAM of the trolley control system is defective
Possible cause:
Hardware fault: replace the communications unit (see Section 7.5 Communications Unit’).
Error No. 407: "Communication with table interrupted"
Possible causes:
Fuse F1 on the input side of the components table-transformer is defective: determine the cause and
replace the fuse (see Section 7.3 ’Components Table Power Supply’).
Interface connector or voltage supply plug has been pulled or there is a bad contact or cable break-
age: check plug connection, if necessary, replace cable.
7.2.1.1 Faults in the Empty Tape Cutting Device
Tape back-up in the empty tape channel / tapes are not being cut
Possible causes:
The motor of the tape cutting unit is not being activated:
The +30 VDC fuse of the communications unit (connections panel) has blown.
Bad plug connection at the tape cutting unit or at the communications unit.
Motor current being switched out by the overload protection (PTC thermistor, communications
unit):
Cutter wheel is stiff-running; pretensioning of the cutter wheel is too strong; continuous or cut
toothed belt is overtensioned; guide rail and carriage for the cutting movement have not been
maintained (see User Manual section 9).
Break in the motor cable (motor plug X3ak); motor is defective (for replacement see Section
7.6 ’Empty Tape Cutting Unit and Empty Tape Channel).
The carriage has driven onto the right-hand stop: right-hand limit switch is defective, or there is a
break in the limit switch cable (leading to the motor current being switched out by the PTC ther-
mistor).
The cutter wheel carriage does not return to the parking position (after reaching the right-hand
limit switch it remains where it is): break in the "Home position" cable or in the left-hand limit
switch.
The carriage has driven onto the left-hand stop: left-hand limit switch is defective, or there is a
break in the limit switch cable (leading to the motor current being switched out by the PTC ther-
mistor).
The cutter wheel is worn out (it was not inspected in the course of maintenance - see User Manual

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".
