Vacuum Test

Service Manual SIPLACE Placement Heads DLM3/DLM4 77

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 position "nozzle open" the

vacuum area is sealed by two seal rings against the

atmosphere.

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

vacuum area is sealed by only one seal ring (at the

rear next to the motor).

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

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

Replacing the DLM4 head

The DLM4 head can be replaced as part of service work.

► If the DLM4 head is fixed to an adapter plate, this will need to be taken off the old head and

fitted to the new one.

Adapter plate DLM4

The adapter plate hardware is designed for quick head

replacement (e.g. for maintenance). It has captive screws

and an eyelet for initial fixation of the head to the head

mounting plate of the gantry.
