Vacuum Tooling for HS-50 Retrofit Instructions / User Manual

5 Preconditions and Restrictions Edition 12/00

– As customary in the entire working area of the placement heads, the option “vacuum too-

ling”, in particular its vacuum plate (top plate of the tool) and suction cups must be kept free

of components or other foreign bodies.

 5HVWULFWLRQV

– Use of the vacuum tooling must be coordinated with Siemens insofar as the spectrum of PCBs

to be populated is concerned.

– The suction cups subjected to vacuum must be completely covered. Vacuum branches of suc-

tion cups which are not covered must be shut off by hand with manual shut-off cocks.

– It is not permissible to use the width adjustment without conveyor bracing.

– The vacuum tooling option automatically cancels the "decrease width" function of the conveyor

width adjustment feature.

– Details on setting the time interval for reducing the vacuum are contained in the chapter "Set-

ting the Time Interval for Vacuum Reduction", Section 3.

The position of the stopper is restricted to a middle position by the opening in the tool of the va-

cuum tooling. 

DANGER

The doors in the machine base are only to be opened by personnel authorized to do so!

– Check the position of the option on the lifting table (see Section 5.1, subitem: "on the option:").

There must be assurance that the PCB is optimally drawn against the suction cups and the

vacuum tooling must be outside admissible ranges of disturbances.

– Connect the "vacuum tooling" to the conveyor control TSP 100 (item no. 00329219) or TSP

200/200M (00349302 / 00359302).

WARNING

Not until this electrical connection is established is it no longer possible to adjust the width. If this

electrical connection is not made and the automatic width adjustment unit is triggered in this con-

dition, the machine will be damaged (see Section 5.2)! 

– Connect the 5.5 bar compressed air branch inside the machine to the vacuum generator of the

vacuum tooling (see Fig. 3 - 1).

– When the vacuum tooling has manual shut-off cocks, the vacuum branches must be closed or

opened in accordance with the length of the PCB to be populated (see Fig. 3 - 1).

NOTE:

All of the suction cups of vacuum branches which are switched on must be completely covered.

If the vacuum is to be maintained, suction cups not covered by the PCB are not to draw any air!.

– Place the stopper in the middle of the conveyor by width (= middle of the PCB).

The positioning range of the stopper is restricted by the opening in the tool of the vacuum too-

ling.

– Make certain that the vacuum plate is clean and free of foreign bodies, such as components

(see "Maintenance", section Section 9).

7 Troubleshooting Edition 12/00

 7URXEOHVKRRWLQJ

NOTE

Error message 232 can be triggered by either errors on the part of the option "vacuum tooling" or

by errors during the lifting table sequence itself.

As in the standard transport sequence, errors during the transport sequence for the PCB or the

check for presence trigger the appropriate error messages.

NOTE:

This error can not be caused by the vacuum tooling.

NOTE:

The lifting table does not move down until the time set for the reduction of the vacuum has elap-

sed.

If the waiting time for the lifting table is exceeded (about 3 sec), this results in a time-out with

error message no. 232.

–

Situation 1: "Lifting table d i d actually move down" (visual inspection):

There is an error in the lifting table sequence which does not involve the option

-> Further troubleshooting: see service manual.

Situation 2: "Lifting table did n o t move down" (visual inspection):

NOTE:

First check for one of the following error situations involving the option “vacuum tooling”. If

not, the error is lies with the lifting table (signal: “Lifting table down” is not issued)-> Further

troubleshooting, see service manual.

– Time interval for “Reduce vacuum” too long / set wrong -> Set time interval (setting to be

made only by persons especially trained for this work by Siemens (see section 4).

– Wiring error the drive "vacuum tooling" (after problem resolution work) -> Check wiring and

correct problem or notify Siemens SMD Service.

– Drive faulty -> Exchange appropriate “Drive for vacuum tooling” (see “Spare Parts”) ->
