Replacing the Cooling Tubes for the Y Axis Motor Cooling System [03003704 -xx]
General Notes
When only one gantry is installed, there are two different cooling tube sets. Make sure that the cooling
tubes are always replaced with ones of the same type: replace black tubes with black tubes and white
tubes with white tubes.
Parts
▪ Cooling air set (black) [03003704-xx]
▪ Cooling air set (white) [03030955-xx]
Overview
General installation
1. Cooling tube connections on the Y axis motor
2. Trailing cable console
3. Trailing cable profile
4. Cooling tubes
► Depending on the trailing cable used, the two tubes
(1) may need to be shortened to the required length:
⇨ Trailing cable for 1 gantry = 1011 mm
⇨ Trailing cable for 2 gantries (1/3) = 921 mm
⇨ Trailing cable for 2 gantries (2/4) = 1086 mm
CAUTION!
Both tubes must be exactly the same length.
To be on the safe side, compare the length of the new
tubes with the length of the old tubes.
► Cover existing stationary cameras with suitable ma-
terial to prevent contamination.

► Use cable ties to fix the two tubes at the top.
► Push the two cooling tube fixtures (3) onto the tubes.
For easier fitting, you can apply a little grease (Molykote) to the spacer of the black cooling tube.
► Fit the two cooling tube fixtures (3) to position 5 (4) and 10 (5) in the trailing cable profile (6).
Installation of black and white cooling tubes
Observe the following for white cooling tubes!
CAUTION
Observe the preferred direction during installation!
► Observe the curvature (preferred direction) of the tube.
► Push the two cooling tube fixtures (1) onto the tubes
(2).
► Fit the two cooling tube fixtures (1) to position 5 (3)
and 10 (4) in the trailing cable profile (5) - from below.
► Note: For black cooling air tube only:
Carefully lubricate the cooling tubes with a small
amount of grease (Molykote).
► Push the gantry into the first end position (the long
part of the trailing cable is at the top).
► Check how the tubes are run in the trailing cable pro-
file. Make sure the tube is neither too short nor too
long - depending on the relevant travel range. The
following photos should help you to assess how well
the tubes have been run.
► Insert the two support rollers into the holes (1) provid-
ed in the power track chain.
► Push the gantry into the first end position (the long
part of the trailing cable is at the top).
CAUTION!
Do not lubricate white cooling tubes!
Do not apply grease to the white tubes.
► Check how the tubes are run in the trailing cable pro-
file. Make sure the tube is neither too short nor too
long - depending on the relevant travel range. The
following photos should help you to assess how well
the tubes have been run.

Checking and assessing how the tubes are run
(1) Good condition – the tubes are run along all positions
of the axes in the trailing cable profile.
► Move the gantry to the second end position and then
back again to the first end position. The long trailing
part will be at the bottom for the second end position
and at the top again for the first end position.
(2) Poor condition – the tubes are run in a slight loop .
► Shorten the tubes by approx. two to three mm.
► Move the gantry to the second end position and then
back again to the first end position. The long trailing
part will be at the bottom for the second end position
and at the top again for the first end position.
CAUTION!
Extract tubes carefully
If you need to extract the tube again, never pull it out of
the connection tubes with force (this could stretch the
tubes).
Gently lever the tube out with a screwdriver or similar
tool.
