4.4.1 Rejecting hoisted components
If the component sensor measurement finds out that a component is still attached to the nozzle after
placement operation, the system attempts to reject the component. A component sensor measurement
rechecks the component rejection.
- If an error is detected, the placement operation is interrupted with a fatal error.
- If a component is detected with the component sensor, the segment concerned is deactivated.
- If the component sensor measurement does not detect any component still attached to the nozzle, a
vacuum check is additionally performed. If a bad vacuum difference should be detected (delta too
small between vacuum open/closed), the segment will be deactivated as well.
4.4.2 Deactivating and activating segments
The software treats a deactivated segment like a segment without nozzle and it will not be used for
placement anymore.
A nozzle is deactivated if the component sensor detects a component after placement and this
component cannot be rejected.
- This component sensor measurement is performed for all components (that are accordingly
configured in SIPLACE Pro) before pickup.
- The measurement is also performed for components whose size and availability have to be checked
before placement, if no further component shall be picked up with this nozzle after placement.
The target and actual states of the nozzle configuration are displayed in the individual functions.
In this way, the deactivated segments may be identified. The nozzles concerned have to be replaced at
the head and activated by confirming the nozzle configuration.
Note:
If a segment is deactivated, a warning lamp flashes to display this state. This flashlight signal
will be overwritten by other lamp states that might follow. Starting to place a PCB will reactivate
the flashlight signal.
The placement performance decreases with deactivated segments.
If the PCB cannot be completely placed due to the deactivation of a segment, the machine
stops with a track empty error.
4.4.3 Automatic change of deactivated nozzles
The nozzle configuration is checked at each start of a PCB processing. Thereby, deactivated nozzles
are detected and dropped into the reject box.
Deactivated nozzles can automatically be replaced, if the "Change deactivated nozzles" button ist
activated in the machine options. New nozzles are picked up automatically as long as the same type is
available in the nozzle changer. After a height reference run, the placement process continues again.
If no further nozzles are available, a nozzle configuration error occurs and the "15520 Automatic nozzle
change is not possible" error message is displayed.

4.4.4 Restrictions
- Placement levels are not supported.
- Repair placement may be performed several times on positions without considering that thus the flux
media thickness reduces.
- Before a setup change, deactivated segments must be activated or the nozzles have to be removed
from the deactivated segments. Otherwise the system would probably try to pick up a new nozzle,
although a nozzle is still available.
- No automatic change of deactivated nozzles will be performed during the replacement operation.
- If the PCB cannot be completely placed due to the deactivation of a segment, the machine stops
with a track empty error. In this case, no automatic nozzle change is possible.
4.5 Integration of the "Deactivating Tape Cutter" Special Design
In this software version the tape cutter can be deactivated via the Software Options (please refer to the
Online Help system for the station software).
If the tape cutter is deactivated, the tape cutter task is not triggered by the software anymore. This
applies for all requests such as placement process and SITEST.
The option dialog has been adapted correspondingly as follows:
- The options are now customized to locations instead of gantries.
- The "With placem. of comp." and "Stop if Vision error" options can only be selected for the entire
machine.
- The "With comp. table" and "Disable tape cutting unit" functions are available for all locations.
This adaption was necessary to enable the individual selection of these options for each loacation on a
machine with one location per placement area.
4.5.1 Activating the function
¾ Select "Options / Software Options" in the Main menu to change into the options dialog.
¾ Select the corresponding location, click on "Disable tape cutting unit" and confirm the selection with
the "Accept" button.
Subsequently, the Software Options icon appears in the Main menu.
The "Disable tape cutting unit" option is stored in the registry, so that the state remains after a reboot.
4.5.2 Restrictions
After a reconfiguration (component table / MTC) possibly all locations might not be available in the
Software Options before the first reference run.

5 Features
5.1 The new features of a 505 system controller
The table below shows all the new features of the 505 station computer software for the different
machine types. A distinction is made between the basic version and the full version of the 505 station
computer software.
