The platter is 16 Inches (406mm) in diameter and contains (20) 1/4-20
tapped holes for mounting. These are located on bolt circle diameters of:
(8) - 15.0 In BCD, (8) - 9.0 In BCD, (4) - 3.0 In BCD.
The platter is strongest in the center, and weakest at the rim. The fixture
being attached to the platter should have its own rigid surface strength and
not depend on that of the platter. It is always best to concentrate the load
in the center region of the platter.

Analog Input
This selection will enable/disable the Analog Input feature.
When enabled, the LT360 will respond to the DC voltage at
the analog input BNC connector. When it is disabled, it will ignore that
input. If you are not using the analog input, this input
must
be disbaled.
Otherwise the LT360 will be controlled by any noise received at the input.
■
Pulse Input
This selection will enable/disable the TTL Pulse Input feature.
When enabled, the LT360 will respond to TTL pulses at the
BNC connector. When it is disabled, it will ignore any pulses. If you are not
using the Pulse Input, it is probably best to keep this feature disabled to
prevent false triggering due to any noise pickup at the open connector.
■
Pulse Direction
This selection controls the behavior to a pulse at the
Pulse Input
BNC connector. Values are CCW or CW,
meaning Counter ClockWise or ClockWise. When a pulse arrives at the
Pulse Input
BNC input, the platter will rotate either CCW or CW as defined
by this setting.
■
Pulse Trigger
This selection controls the trigger for the
Pulse Input
BNC
connector. RISE or FALL means that triggering will occur
on the rising or falling edge of the pulse.
