7.2 Fault Characteristics
Carry out preliminary fault location with the aid of fault characteristics listed below and their possible causes.
The order in which the possible causes are given here represents the best way of proceeding as far as the
amount of work and the probability of the fault are concerned.
For detailed information on further location and correction of the fault please refer to the corresponding sec-
tion of this Service Manual.
DANGER OOO
Please note with all fault correction work the safety instructions in the User Manual.
Please note in addition:
In the machine base interior the 400 VAC operating voltage is still present in certain modules even when the
main switch is switched off.
All work in the machine base interior must therefore only be carried out by authorized persons who have had
the appropriate training.
During all work in the machine base interior you must comply with the special VDE 0113 electrical safety reg-
ulations and disconnect the machine as soon as possible from the mains supply.
This also applies to all work on the power supply unit of the components changeover table (transformer T1
below the components table).
7.2.1 Faults with Error Message
– With "Track error" the corresponding placement head moves over the board conveyor so that the feeder
modules can be topped up.
– In the menu "Components feed" after you select the function "Display track errors" you will be provided
with a complete overview of all errors which have occurred. These errors will be accumulated if they are
not deleted after correction (setter function "Set all full").
– The current error is displayed on the top line.
– More detailed information on track error menus 1 and 2 will be found in the User Manual.

NOTE
Please note the following, before you switch the machine off in the course of fault location and correction
work, or make a change in the compressed air circuit:
First quit the track error menu with "Abort placement" so that all components picked up at the revolving head
in the course of the reference run can be dropped into the rejects container.
After this switch off the machine at the main switch, or subsequently modify the compressed air circuit or the
compressed air unit (for example, in connection with the "components table pneumatic system"). Otherwise
the components will drop uncontrolledly into the machine and will there be the cause of further faults!
If you are however able to correct the fault without taking the steps just mentioned - for example, by correcting
a feeder module fault - then the components will remain picked up. Once you have corrected the fault, select
from within the "Track errors 1/2" menu the function "Continue placement".
CAUTION OO
After "Abort placement" the placement head will be in the stand-by position above the corresponding compo-
nents supply unit!
Before removing the feeder modules or moving out the components changeover table you must therefore
always first move the placement head by hand to a position within the PCB conveyor.
To do so without damaging anything, hold the placement head (when the machine is switched off) only by the
handle or press against a suitable part of the gantry carriage.
Please note: A minimum separation of the axes must be complied with (crash switch!) or restored before the
machine is switched back on! For this reason when the conveyor width is narrow always position only one
axis by hand above the board conveyor.
● Error No. 43: "Component not at nozzle after pick-up" ("Track empty" after the 3rd attempt to pick up)
Possible causes:
– Fault in the tape feeder module: the pick-up position was not correctly adjusted, the tape is not being
transported: See Feeder Modules’ user manual.
– The power supply to the module is interrupted at the connections panel or the control signal for tape
feeding is not being given: fault in the communications unit.
– Fault in the tape transport caused by faults in the empty tape cutting unit (tape jams, etc.): See Sec-
tion 7.2.1.1 ’Faults in the Empty Tape Cutting Device’.
– The vibrator feeder (vibrator) in the activated feeder sector (location 1 or. 3) is not conveying or is
doing so incorrectly: See Section 7.2.1.2 ’Fault in the Vibrator Activation’.
– Fault in the compressed air feeder module or in the actuation of this module (output from the commu-
nications unit) or in the 5 bar compressed air branch for the components table compressed air supply:
See Section 7.2.1.3 ’Fault in the Components Table Pneumatic System or Components Table Com-
pressed Air Supply’.
– Machine data for tracks 1 or 120 are not correct: Check this with the SITEST program.
– Faults in the placement head (faults: vacuum, nozzle, etc., see Service Manual, Section 9).

● 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
