Balancing The Payload
DO NOT ATTEMPT TO BALANCE THE PAYLOAD
UNLESS YOU HAVE AT LEAST TWO OTHER PEOPLE
TO HELP YOU.
For proper operation of the HS-2010MED pan/tilt heads it is very important that
the payload is mechanically balanced horizontally (forwards and backwards)
and vertically. This ensures that the center of gravity is exactly on the tilt axis
and the load on the servos is balanced.
Horizontal Balance
Make sure that the head power switch is Off.
1.
If the payload stays in the horizontal position without support it is already
balanced.
2.
If it is not balanced, have two or more people support the payload, release
the Slide Lock and move the payload forwards or backwards until it is bal-
anced.
3.
Tighten the Slide Lock and recheck the balance. It is best to move the pay-
load in small increments even though this may require several steps until
the balance is achieved.
Vertical Balance
Once the horizontal balance is set, you can adjust the vertical balance.
1.
Manually tilt the camera approximately 45° upwards and release it. If it
continues to move upwards, the payload is mounted too high. Or, if it
moves back towards the horizontal position when you release it, the pay-
load is mounted too low. If the camera stays in the same position when
released, the payload is properly balanced vertically. Tilt the camera 45° in
the other direction and release it and check balance again.
2.
Mark the starting position of the tilt cradle so that you can keep track of
how far you move it as you set vertical balance.
3.
This step requires several people, since it is impossible and unsafe for just
one or two people to accomplish it. While two or more people support the
weight of the payload, use a 1/4” right angle hex key to loosen the four tilt
cradle mounting screws.
4.
Based on the test in step 1, raise or lower the payload and tilt cradle a small
amount. Tighten the four screws securely.
5.
Repeat the test in step 1 and repeat steps 3 and 4 until vertical balance is
achieved.
