L-350 MECHANICAL INSTALLATION GUIDE
MOUNTING DRIVE-BASE TO PIER
Mounting (Alt-Az-specific concerns):
Leveling:
L-series mounts are fully capable of operating
in Alt-Az when not well leveled. However, the
drive-base being off level will result in the fol
-
lowing challenges (which increase with the ex
-
tent to which it is off level):
- Pointing and tracking, prior to building a
model, will be incorrect and complicate the
process of building an initial model.
- Balancing in Azimuth becomes more critical,
to prevent this axis from wanting to rotate.
Leveling should ideally be achieved through
proper construction of the pier, not through
uneven elevation of the drive-base over a
non-level mounting surface.
Orientation of NoWrap position:
Please note that accuracy of the NoWrap posi
-
tion to the cardinal directions noted below will
effect tracking, prior to building a model. The
L-350’s NoWrap marker is a notch in the base-
flange, adjacent to the Azimuth Lock (visible in
the models on page 12).
Northern-hemisphere:
The “NoWrap” mark on the Aziuth-Motor/Base
should face true-south.
Southern-hemisphere:
The “NoWrap” mark on the Aziuth-Motor/Base
should face true-north.
Before beginning, be sure that cable-routing
has been addressed. The power and communi
-
cation (USB/Ethernet) cables are meant to exit
through the bottom-center of the drive-base.
If a metal pier or extension is being used, it
should have holes available for both entry and
exit of these cables.
If a concrete pier is being used, it should have
had a conduit placed at its top-center (exiting
out some position on the side of the pier) or a
channel in the top (from center to edge) allow
-
ing the drive-base to sit firmly and flush on the
pier without interference from the cabling.
Installing the base motor onto the pier:
1) Lift the drive-base onto the pier (or interface
plate), making sure that the “No-Wrap” marker
is correctly oriented (see above), and that ca
-
bles are properly routed into/over the pier.
2) Secure the drive-base, inserting the bolts
through the hole-pattern around its bottom
flange and lightly tightening them. To ensure
that all go in easily, wait until all are engaged
before fully tightening any of the bolts.
