● Conversion Criteria (if nozzles are missing)
1. The additionally required nozzles are assigned to the free compartments of the Nozzle Changer.
2. Setup Optimization attempts to place all the other required nozzles into compartments which are
occupied by a nozzle type which is available in the Nozzle Changer several times.
Example: If compartments 2 and 4 have been assigned nozzle type "316", Setup Optimization
tries to place the required nozzle type into compartment 2 or 4.
3. Setup Optimization replaces all nozzles that have been allocated to the Nozzle Changer but are
not required, with nozzles that have not yet been set up but are required for the particular setup.
Setup of Waffle-Pack Changer
Waffle-pack magazines (WTs) require waffle-pack tray carriers (WTCs).
The allocation of WPTs to WPCs is performed with the aid of the Feeder Editor.
WTCs are automatically included in the setup created by the Setup Optimization (just as modules are set up if,
for example, a 4.5 mm or 9.5mm linear feeder is required).
NOTE
Empty WTCs set up at a configured station or as part of a fixed setup are not
assigned waffle-pack trays
by Setup Optimization.
For each WTC a maximum of one waffle-pack tray is set up.
(The assignment of several waffle-pack trays to a particular WTC can be specified in the fixed setup).
Manually loaded WTCs are automatically included in the setup.
Feeders are only placed underneath a manual WTC of the HS-180 if a fixed setup has been preset in which
feeders are to be set up underneath the WTC.
Head camera and CRDL Tester are not set up automatically
NOTE
Head camera and CRDL Tester must have been configured at the station by means of the Configuration
Editor prior
to the use of the Setup Optimization (see chapt. 12) if components are present that have to be
centered optically or require CRDL measuring.

11.3.3.5 Machine Restrictions Taken Into Account
In the Setup Optimization the following restrictions relating to the IC head or turret head have been taken into
account for the following procedures:
IC Head
● External mechanical centering
If a component is to be centered by means of the external mechanical centering station it may only be placed
by the IC head if an external mechanical centering station is available that can be accessed by the head.
● External optical centering
If a component is to be centered by means of the external optical centering station, it may only be placed
by the IC head if an external optical centering station is available that can be accessed by the head. Moreover,
at least one sensor type contained in the package form description of the component (see chapt. 6) must
be identical to the sensor type of the optical centering station.
● Coplanarity Measurement
If a coplanarity measurement is to be performed on the component, and if a coplanarity module is available
on the line, the component may only be placed by the IC head if the coplanarity module can be accessed
by the head. Moreover, at least one sensor type contained in the package form description of the component
(see chapt. 6) must be identical to the sensor type of the coplanarity module. If no coplanarity module is
available on the line, the component may be placed by the IC head without these restrictions applying.
● IC Disposal by Means of Disposal Belt
If in the case of faults the component is to be disposed of on a disposal belt and if such a device is available
on the line, the component may only be placed by the IC head if the IC disposal belt can be accessed by
the head. If no IC disposal belt is available on the line, it may be placed by the IC head without this restriction
applying.
Turret Head
● Centering on the head by means of jaws
If the component is to be centered on the head, it may only be placed by the turret head if the head is
equipped with jaws.
● Centering by means of head camera
If the component is to be centered by means of a head camera, it may only be placed by the turret head if
a camera is available on the head. Moreover, at least one sensor type contained in the package form
description of the component (see chapt. 6) must be identical to the sensor type of the head camera.
● CRDL Test
If the components requires electrical testing, it may only be placed by the revolver head if a CRDL measuring
system (measuring jaws, measuring board) is available at the head. If no CRDL measuring system is
available on the line the component can be placed without any restrictions to be observed. A corresponding
warning will be displayed.

● Nozzle Changer and Manual Tray
A nozzle changer for the revolver head and a manual tray must never be set up simultaneously on one side.
● Feeders at the Border Regions of Feeder Parts
Certain feeders must not be set up in the border region of feeder parts as otherwise the component
pick-up divisions are located outside the travel range. This is taken into account.
11.3.3.6 Capacities Taken Into Account For Setup Optimization
● For setup optimization the following capacities are taken into account:
● All feeder types known to the system are supported irrespective of the head type.
● The space available (track allocation) to the feeder parts must not be exceeded.
● Allowance is made for the individual space requirements of each feeder and each module. Each
compartment of a feeder can be assigned components. Feeders requiring modules for their setting
up in the feeder part are placed into modules.
Waffle-pack magazines are placed onto waffle-pack tray carriers.
IC Head
● The IC head can access all feeder parts that lie within the reach of its portal.
Turret Head
● The turret head can access all feeder parts that lie within the reach of its portal with the exception of the
Waffle-Pack Changer feeder part.
11.3.3.7 Inclusion of Feeders in Clustering
As soon as more than one setup is calculated, setup changeover operations between setups play a role.
Optimization takes these setup changeover operations into account. Each feeder of the initial setup which is
not set up in the follow-up setup with the same component type on the same track, is considered a feeder setup
changeover operation. In this case, the time expended for the setup changeover is merely the time required for
exchanging the previous feeder for the new feeder. The feeders themselves are considered as having been
preset with the respective component type.
The setup changeover time per feeder can be entered together with the optimization parameters (see section
11.4.3.1).
Effects:
- Short setup changeover time: More feeders are set up in the fixed feeder part.
- Long setup changeover time: Fewer feeders are set up in the fixed feeder part.
