4.5 Errors
Service Manual SIPLACE LDU-X Linear Dipping Unit 11/2017 75
Errors: A significant amount of flux is leaking from the dip plate, on the left and /or
right.
Display: normal
Status display: normal
Cause: The flux tank is not sealed properly where it meets the plate. There may be un-
evenness, scratches, components on the plate or in the tank.
Solution: Check the zero position of the dip plate.
Check the contact pressure for the flux tank.
4.5.3 Insufficient Flux Layer
Errors: A significant amount of flux is leaking from the reverse position of the LDU-X.
Display: normal
Status display: normal
Cause: The flux tank is not sealed properly where it meets the plate. There may be un-
evenness, scratches, components on the plate or in the tank.
Solution: Check the zero position of the dip plate.
Check the contact pressure for the flux tank.
4.5.4 Flux Tank Blocked
Errors: The flux tank collides with the dip plate (rubbing marks, sounds)
Display: Normal
Status display: Normal
Cause: The dip plate is not standing level with the home plate and forms a difference in
height as the interface. The flux tank scrapes over this "step" or hits in when
moving.
Solution: Check the Z height.
Check the gap at the interface.
Check whether there are contaminants (components) at the interface.
4.5.5 Initialization not Successful
Errors: The initialization run was not completed successfully. A significant amount of
flux is leaking from the reverse position of the LDU-X.
Display:
Status display: Red LED lights up
Cause: The flux tank is not sealed properly where it meets the plate. There may be un-
evenness, scratches, components on the plate or in the tank.
Solution: Check the sensors for the axes.
Check whether the switching flags for the axes still cover the sensors after the
initialization run.
Check the communication with the placement machine.
Check the USB port address.
Check whether the end position switch in the Z direction is reached during X
direction movement (green LED on the LDU control board). If needed, increase
the distance from the end position switch to the zero position.

4.6 Maintenance: greasing the spindle and guidance
76 Service Manual SIPLACE LDU-X Linear Dipping Unit 11/2017
4.5.6 The axes won't move
Errors: The axes suddenly stop while moving.
Display: X axis or Y axis error
Status display: Red LED lights up
Cause: The control circuit for positioning is overloaded and the control system stops
the movement.
Solution: Reduce the speed of the axis concerned (see "Parameters").
Increase the "tracking error" parameters.
4.5.7 Position Error
Errors: The axes suddenly stop while moving.
Display: Position error
Status display: Red LED lights up
Cause: The control circuit for positioning is overloaded and the control system stops
the movement.
Solution: Reduce the speed of the axis concerned (see "Parameters").
Increase the "tracking error" parameters.
4.5.8 Step Loss
Errors: The axes suddenly stop while moving.
Display:
Status display: Red LED lights up
Cause: The control circuit for positioning is overloaded and the control system stops
the movement.
Solution: Reduce the speed of the axis concerned (see "Parameters").
Increase the "tracking error" parameters.
4.6 Maintenance: greasing the spindle and guidance
All LDU-X guides and spindles must be greased every 6 months or more often if required.
Grease with ISOFLEX Topas 5051 (03078517-04).
► Grease the guidance(1) and the
spindle(2) evenly and along the whole
length.
► Also grease the spindle and guidance on
the other side of the LDU-X.
