6.5.11 Performing a Vacuum Test on the C&P 6/12 DLM Heads Collect&Place Head

Service Manual SIPLACE D1/D1i/D2/D2i 241

Vacuum test with closed nozzle

► Start SITEST and perform the first reference run, if

required.

► Select the gantry for the required vacuum test on the

C&P6/12 placement head.

► Place all the nozzles for the placement head in the

nozzle changer.

► Replace the full magazine at one magazine position

with the magazine holding the test nozzles

[03067029-01].

► Go to the Nozzle on head for segment 1 menu and

select the nozzle type which was originally configured

for this magazine position.

► Select the checkbox All segments as segment 1

► Pick up the vacuum test nozzles with all segments.

► Select the vacuum test menu and perform a vacuum

test.

► The error message Vacuum difference open/closed

too low can be ignored here.

▪ As you can see in the measurement values here, the

Open values deviate by up to 3mbar from the Closed

values.

▪ However, this is within the tolerance of 5 mbar, in

which correct function can be reliably assumed.

► If this tolerance value is exceeded, check the valve

plunger and vacuum plate and replace these a a pre-

caution, if necessary.

Scenario 1

Example of faulty vacuum values, which indicate a dam-

aged vacuum plate at segment 2 here.

NOTICE! Irreparably damaged vacuum plate

If both measurements for a particular segment are

around 640mbar, this indicates that the vacuum plate is

irreparably damaged.

Maintenance recommendations:

▪ Use the valve plunger ONLY when greased. (Isoflex topas).

▪ Replacing the valve plunger also means:

– Clean the valve plunger housing! Otherwise good plungers with new grease are installed in the

old, contaminated environment.

– Grease the valve plunger: Use the appropriate tool [03049689-01] to grease the valve plunger.

– Perform vacuum tests with the red SOKO nozzles, vacuum test DLM [03067029-01].

▪ Regularly check the sleeve-nozzle vacuum plate "blue" (available from 10/2008, white) and replace

when necessary (with 1.5mm Allen key).

▪ Set the air blast tube so that it overlaps the circular guide frame by 0.7 mm.

Scenario 2

Example of defective vacuum values, which indicate a

damaged silicone hose on segment 1 and an open nozzle

at segment 3.

NOTICE

Silicone hose defect

Under certain circumstances, silicone hose defects might only be detected when the segments

are moved out. It could therefore be advisable to release the Z axis and to perform a vacuum

test of the segment in its lowered state (single measurement run).

NOTICE

Missing valve plunger

If both measurements for a particular segment are only around 210mbar, this indicates that the

valve plunger is missing.

Vacuum values and valve plunger positions

▪ If the valve plunger is in the position "nozzle open",

the vacuum area will be sealed against the environ-

ment with two seals.

▪ If the valve plunger is in the position "nozzle closed",

the vacuum area (at the rear, near the drive) will be

sealed against the environment with only one seal.

If the "vacuum value closed" is too low, this indicates that

the seal is not sufficiently greased or that it is damaged.
