► Remove the Vision processor subboard from the gan-
try head distributor. (See "4.2.13 Replacing the Vi-
sion Processor Subboard [03040460-xx]" [ ➙ 80].)
► Unplug all electrical connections from the top (upper
side) of the gantry head distributor and label these for
easier reconnection, later.
► Loosen the 5 screws fastening the gantry head dis-
tributor.
► Detach all electrical connections from the bottom (un-
derside) of the gantry head distributor and label these
for easier reconnection, later.
► Remove the gantry head distributor.
► Remove the TQM module (2) from the old gantry
head distributor and fit it on the new one. You may
need to loosen a screw on the TQM module.
► Where necessary, remove the hexagon spacer bolt
from the old gantry head distributor and fit it on the
new one.
► Fit the new gantry head distributor and the Vision pro-
cessor subboard by following the instructions in re-
verse order.
► Fix the cables, so that they are not subject to vibra-
tions or shearing.
► Set the jumper S1 (1) correctly. (See "6.2.3.1.1 DIP
Switch on Gantry Head Distributor" [ ➙ 208].)
CAUTION
Do not damage the fixture clips!
To disconnect the component and PCB camera connections, you need to open the fixture clips
by applying pressure to the side of the connector.
► For details see "4.4.22 Press Fit Connections with Fixture Clips on the Vision Board (D Se-
ries)" [ ➙ 157]
