General
Please read this BM-11-401 Mount installation manual carefully in order to profit fully from its benefits.
Take care that the mounts and load cells are applied within their specifications. Certainly during
installation special attention should be paid to exceptional forces exceeding these specifications.

Assembly
Before installing the mount into the application, the stay rod assembly should be removed. The mount
should be assembled and set to the installation height at which the load cell is not loaded:

Assemble the mount as follows:
•Assemble the mount (without the load cell) as shown in picture 1, taking care that the top and
base plates are correctly aligned (vertically).
•The top plate (see drawing and Part List pos. 10)
should be locked at installation height using the socket
head counter sunk bolts (pos. 9) and the upper nut
(pos. 7, see picture 1).
Note: the long bolts must not protrude above the top
plate. This can cause weight on the long blots and that
will distorts the measured value.
•Then the socket head counter sunk bolts (pos. 9)
should be locked securely by turning the thin nut (pos. 6) Picture 1
downwards to the base plate (pos. 1).
Then the mount is ready to install in the application of the customer.
Installation
Important to know is to install multiple mounts in such a way that all bottom plates are at the same
level and in the same horizontal plane. The same goes for the top plates. Always use shim plates to align
mounts in the same horizontal plane and level. Always check that load cell and/or mount are not loaded
with forces exceeding their specifications.
Install as follows:
•Locate the mount into the application and secure using the four lower and two upper
fixing holes. Two hexagon bolts (1 upper and 1 lower) should be used to secure the earth cable
(shown in Part List drawing pos. 14-15)
•Coat both bearing load surface (pos. 13) (see picture 2) with ‘high pressure’-grease and locate
the rocker pin support . Insert the rocker pin with lower bearing (pos. 11) in the load cell (see
picture 3) and slide the load cell into place, ensuring that the rocker pin (pos. 13) is properly
located (see picture 4).
•Place the load cell in the mount by putting it between the bottom plate and top plate in a half
turned position and put it upright ensuring that the rocker pin is properly located in the right
position
Warning: For safety reasons, always use a tool to align the rocker pin if necessary during
this process, don’t ever use your hands.
•Secure the load cells with the bolts (See Table 2) (pos. 3). Make sure that the washers (pos. 3 &
4) are placed and that the correct torque (see Table 1) on the bolts is used (see picture 5).

•Then rotate the upper nut (pos. 7) counter clockwise by 1/2 turn at a time until the full load is
taken by the load cell. Gradually apply the load to the load cell. This is done by lowering the
upper nut underneath the top plate one-by-one with small steps. This way no exceptional high
forces are introduced to the mounts or the load cells.
Warning: For safety reasons, always use a tool to align the load pin if necessary during this process.
•Check the free movement of the mount and its installation height, whether the socket head
counter sunk bolts are touching the application or not and the free movement of the top plate
If the installation height is correct, the bolts are not touching the application and the top plate is free to
move, then the assembly is ready to be used in the installation.

Use
Routine maintenance includes the optical inspection of bolts, plates and force bearing parts, as well as
the removal of dirt, dust and debris built up near or between the load cell and/or mount in order to let it
move freely.
Finally
A load cell will perform within specifications until the safe load limit or safe side load limit is passed.
Beyond this point, even for a very short period of time, the load cell will be permanently damaged. The
load cell may physically break at the ultimate load limit.
When not working properly remove load cell with care and attach a label with comments relating to the
problem or mode of failure. Return also a copy of the Certificate of Calibration with the load cell if
available.
Don't cut cable at the gland to facilitate removal - please - we cannot test load cells without cables!
