App
all eddy current dynes
Warning
Do not drop the load cell or subject it to harsh shocks.
Note
The load cell cable will have extra length. Coil and store
in dyne under brake cover, away from the EC brake.

1. There will be
a dummy spacer in the load cell location (at the EC brake) during shipping.
Remove it.
2. Install load cell, either side up, with supplied bolts, onto the
torque arm.
3. Adjust eye length so that torque arm is level.
4. Loctite mounting bolt nuts. (located next to the eddy current brake)
5.Connect male screw-in
connector on black speed sensor to female connector on the gray main
