Installation of the control board (optional)
To install the optional control board with rotary
encoder next to the display, holes must be
drilled. To do this, remove the steel profile on
which the display is located. First you must
remove the left end block with the drawbars. It
is attached to the base with four wood screws
from above and two long plastic screws from
below. Disconnect the cable to the front panel
from the slot on the end block.
To place the drill holes precisely, they must be punched. For this
purpose, print out the drilling template shown opposite.
Check
the dimensions
to ensure that the printout is on a scale of 1:1,
i.e. that it has not been enlarged or reduced. Cut out the drawing
along the contour lines.
Place the metal profile upside down on a soft
surface so that it does not get scratched.
Attach the drawing with adhesive tape in the
center of the metal surface, about 6cm next to
the display, with some distance to the screwed-
on strut.
Center punch the five drill holes at the
positions marked with crosses. Pre-drill all five
with 3.2mm. Then enlarge the two drill holes
for the buttons to 7mm. Enlarge the drill hole
for the encoder to 14mm with the step drill.
Deburr the holes on both sides with the step
drill.
Now fasten the control board with the two black screws and connect the 6 core cable. Reassemble the
steel profile with the display and the left end block. When doing so, do not neglect to reattach the ground
connection under the screw on the left and restore the cable connection between the two assemblies.
