Payload Attachment - FLIR PTU-5 User Manual

3. Remove the top mounting bracket by removing the two screws and one clamp at either side of the
bracket.
4. Orient the side bracket so the horizontal mounting arm is on the bottom.
5. Attach the bracket using one clamp secured with two screws torqued to 32 inch-pounds. The thread
holes in the hub come with thread locking compound applied to them. Reapply thread lock to the
hub whenever you remove the bracket using a compound such as Loctite® 242.
6. Reset the PTU and ensure that the bracket moves properly throughout the entire range of motion.
Note: If you ordered your PTU with a top bracket, the unit will arrive with the bracket
already attached.

4.8.2 - Payload Attachment

The following guidelines apply to all payload
attachments:
• Mount all payloads as close to the PTU as
possible. This minimizes the distance between
the payload Center of Gravity (CG) and the
center of rotation of the axes, which reduces
stress on the PTU and mounting. It also
improves performance by reducing the
amount of torque required to move the
payload.
• Verify that the payload will clear the PTU
housing and all surrounding objects
throughout the entire range of motion.
• Your PTU is rated for the loads specified in
"PTU-5 Features" on page
distribution affects the actual weight that the
PTU can safely move. The amount of torque
needed to move a payload depends on a number of factors such as (but not limited to) payload
weight, distance from the payload CG to the center of rotation, acceleration and speed settings,
power levels, and environmental factors.
• The PTU allows full control over acceleration, speed, and power levels. Mount your payload and
configure these parameters appropriately to ensure reliable operation.
• If your installation is not usable across the full range of motion, use the TXU, TNU, PXU, and/or PNU
commands to set software motion limits. When resetting a PTU-5 that is positioned near those
limits, the PTU may briefly move outside those limits.

Top-mounted
payload CG is above
the tilt axis center of
rotation and requires
more torque.
Side-mounted
payload CG is closer
to the tilt axis center
of rotation and
requires less torque.
