2.2 Load Cell Installation V1.2

The load cell must be placed such that the antenna is not in contact with metal as this

will interfere with radio communication between the load cell and the display unit.

Step 1) The load cell has two different pin assembly sizes. Assembly of the load cell and

adapter plates (fish-plates) must be configured to the pin size required by the specific dead end

or hook to which it is to be attached. If the smaller of the two sizes fits the dead end or hook to

which the load cell will be attached, the load cell will be attached to the adapter plates with the

larger pin and the larger adapter plate holes.

If the larger of the two sizes fits the dead end

or hook, the load cell will be attached to the

adapter plates with the smaller pin. In both

cases, the copper bushing must be placed in

the hole of the load cell to which the smaller

pin is destined.

Step 2) The copper bushing must be se-

cured in place by the two hex screws, one to

each side.

Step 3) The spacers should be placed on

the pin linking the load cell to the adapter

plates between the adapter plates and the

cotter pins to inhibit excessive lateral move-

ment of the load cell and the adapter plates

along the pin.

Step 4) If the dead end or hook to be con-

nected to the adapter plates requires a larger

opening, spacers may be placed between the

load cell and the adapter plates.

Step 5) In some cases spacers may also be

necessary on either side of the load cell on

the pin connecting it to the dead end or hook.

In all cases the spacers must be placed

symmetrically such that the load cell is

centered on the pins.

Step 6) Once the pins are correctly placed and spaced, they must be secured with the cotter

pins provided.
