Check the activation of the LED for the 24 VAC voltage on the connections panel.
●
Check the functioning of the new communications unit using the SITEST program or by component pick-
up from this location. After this, start the placement sequence.

7.6.2 Locating the Electrical Fault
NOTE
Error message No. 43 can point to a fault in the tape cutting unit or in the empty tape channel. Start fault loca-
tion by referring to the section 7.2 "Fault Characteristics".
- In addition, in the section 7.1.4 "Empty Tape Cutting Device" you will find information on the electrical and
pneumatic systems as well as the functional sequence for evaluating the fault situation.
- Use the circuit diagrams from the current circuit diagram folder. Details at to which diagram is needed
in each case will be found in the following text.
- In the course of fault location you will require the SITEST program for performing an individual cutting
stroke or starting continuous operation.
DANGER
OOO
When the SITEST program is being used, particularly with the components changeover table removed (but
connected), there is increased risk of accidents at the tape cutting unit involving the cutter wheel and cutter
strip. When the test program is loaded do not reach into the area of the tape cutting unit, not even for fault cor-
rection or to connect up a multimeter, etc. Cordon off the area of the tape cutting unit correspondingly.
With all work, please read and observe in addition the DANGER note in the section 7.2 "Fault Characteristics"
7.6.2.1 Checking the + 30 V Electric Circuit: Fuse, Plug Connections,
Motor Activation, Solenoid Valve
●
Select from within the track error menu "Abort placement" in order to return in the course of the following
reference run all of the components picked up at the placement heads.
●
Check whether fuse F1 of the connections panel of the communications unit has interrupted the + 30 VDC
electric circuit (see Fig. 7.5.1 and circuit diagram 1710470-Y0069-..-L.., Sh. 1).
●
Fuse F1 is defective:
●
Switch off the machine at the main switch.
●
First correct the cause - such as, for example, a short circuit in the limit switch, in the cable Y637-W1/
W2, etc. (for fault location, see below) or in the tape feeder module - and then replace the fuse F1.
●
Switch the machine back on and carry out a trial placement run with component pick-up from the tape
feeder modules of the previously faulty location.
●
If no error message now occurs (the tapes are being cut), start the placement sequence.
●
Fuse F1 is not defective:
●
Load the SITEST program and start the cutting stroke by making the following selection:
"BE table"
→
"Single function"
→
"Tape cutter". Check whether the cutting stroke is being carried out,
the pressure rod is swinging into position, the cutter wheel carriage returning to its parking position on
the left, the motor current being switched off and the pressure rod swinging away.
–
The motor is being switched off after brief activation: there is stiffness in the performance of the cutting
stroke
→
the + 30 VDC electric circuit has been interrupted by the PTC thermistor:
●
Check whether the longitudinal guide of the slide has been maintained (see User's Manual,
