Installation
X Insert the tubes into the new raceway but do
not yet tighten the grub screws which fasten
these tubes.
ATTENTION:
Take care not to bend the tubes.
X Fit the raceway onto the front of the head.
X Fit the raceway gauge onto the motor axis, as
shown in the diagram. Tighten the gauge with
the three screws (1) provided, so that you can
reach all the screws (2) for the raceway and
the Z axis.
X Fit the 0.01 mm feeler gauges (3) on both side
of the Z axis (or the Z axis mechanics gauge).
X Fasten the circular arc guide with the three
screws (2).
X Dismantle the gauge for the raceway.
X Remove the feeler gauges and test the Z axis
for ease of movement.
X With the help of the feeler gauge, adjust the
metal tubes for the air kiss supply to 0.7 mm
higher than the circular arc guide and fix into
place with the grub screws (Allen key,
0.71 mm).
X Attach the silicon hose to the metal tubes and
fix this to the housing with the hose holders.
X Fit the star back into the head. (See section
"Replacing the Star" in the Service Manual.)
Set the zero position with the power pack and
determine the zero point correction value.

Preparatory steps
X Remove the Twin Head from the machine (see service manual).
WARNING: The safety instructions in the chapter Operational Safety in the operating and
service manual take priority.
X The SIPLACE machines are supplied with line voltage.
Parts of the system therefore carry dangerously high voltages! In specific modules the
voltage is present inside the machine base even when the main switch is turned off.
Handling the machines improperly or touching parts thereof which conduct high voltage may
result in death or serious physical injury as well as extensive property damage.
Before you perform any work on the machine, shut down the operating system and then
ensure that the machine is switched off at the main switch and is disconnected from the power
supply .
X In addition, the compressed air supply must be turned off at the main valve of the compressed
air unit, in the machine base, and the compressed air lines must be bled by actuating the
needle valve on the compressed air unit.
X The area around the linear motors presents a risk of lethal injuries to persons wearing heart
pacemakers. Observe the instructions in Chapter "Special safety instructions for working in
the vicinity of powerful magnetic fields" in the operating and service manuals.
X Observe the applicable accident prevention regulations, DIN standards and special safety
codes of your country at all times.
X Read and observe the instructions about residual voltages in Chapter "Operational Safety".
X Always observe the ESD regulations described in Chapter "Operational Safety" of the
operating guide.
X While performing retrofitting work, always secure the machine to prevent unauthorized
reactivation or access by unauthorized persons, as described in Chapter "Locking the
Machine... ".
X There is an additional, high risk of accidents when working with the SITEST program.
SITEST may therefore only be started by specially authorized and trained persons.
