4.7.2 Mounting the 2AP as Positioner
There are several methods of mounting the 2AP as Positioner. The difference is in the desired
display of the given azimuth and zenith readings in the positioner software:
• If you mount the 2AP such that the arrow on the bottom flange (middle of the Azimuth
range) is aligned due North, the displayed azimuth readings will then be a given as True
Azimuth readings, see figure 4.36 a).
•
If you mount the 2AP such that the arrow on the bottom flange (middle of the Azimuth
range) is aligned with your Centre-of-Travel reference, the displayed azimuth readings will
then be a given rotation amount (in degrees) away from this arbitrary centre line, see figure
4.36 a).
•
Or mount the 2AP such that the arrow on the bottom flange (middle of the Azimuth range) is
aligned opposite your Centre-of-Travel reference. With the 2AP in the Home Position,
mount the instruments on the Side Zenith Plates opposite to the arrow on the 2AP bottom
flange, see figure 4.36 b). This allows a Zenith range in a downward direction. As the
instruments on the Side Plates are mounted opposite for a downward Zenith range, the only
consequence is that with respect to True Zenith, the Zenith readings have a 180º offset.
With the determined direction of the arrow on the bottom flange taken into account mount the 2AP
as per sections 4.3 and 4.4. Refer to section 4.5 regarding any 2AP accessory installation, such as
for the optional Tripod Floor Stand and the Large Side Mounting Plates.
