2 Safety instructions
2.1 General notes
NOTICE
Warning of damage to property and/or the environment.
The product was in perfect condition with regard to safety features when it left the
factory.
To maintain this condition and to ensure safe operation, the user must follow the
instructions and observe the warnings in this manual.
2.2 Intended use
The mounting kits PR 6012/02, ../32, ../42 are intended for weighing tasks, and must only
be used as such.
The mounting kits PR 6012/02, ../32, ../42 are designed for installing the load
cells PR 6212 (500 kg–10 t).
The dimensions of all mounting and structural components must be calculated so that
sucient overload capacity is ensured for all loads which may occur while taking the
relevant standards into account. In particular, upright weighing objects must be
safeguarded against the weighing installation turning over or being shifted, thus
eliminating danger to people, animals, or goods even in the case of a break in a load cell
or mounting element.
Installation and repair work must only be carried out by expert/qualied personnel.
The mounting kits reect the state of the art. The manufacturer does not accept any
liability for damage caused by third-party system components or due to incorrect use of
the product.
2.3 Initial inspection
Check the contents of the consignment for completeness. Check the contents visually to
determine whether any damage has occurred during transport. If there are grounds for
rejection of the goods, a claim must be led with the carrier immediately. The
Minebea Intec sales or service organization must also be notied.
2.4 Before operational startup
NOTICE
Perform visual inspection.
Before operational startup as well as after storage or transport, inspect the
mounting kit visually for signs of mechanical damage.

3 Recommendations for installation
3.1 Load cell and constrainer arrangement
Examples:
Key
Do not constrain this position.
Constrainer
Load application
Possible direction of movement
Maxi FLEX and Maxi FLEXLOCK mounting kits PR 6012/02, ../32, ../42 3 Recommendations for installation
EN-6 Minebea Intec

-To ensure the required free moving space of the weighing facility, a maximum of
3 mounting kits with constrainer may be used to constrain a weighing object.
Round containers are the exception (image ① and ②). In this case, any number of
constrainers can be installed, provided that they are tangentially aligned.
Special mounting kits are available for weighing points without constrainers.
Alternatively, the constrainer can simply be removed.
With elastic constructions, it may be necessary to deviate from this recommendation
in order to guarantee the weighing object has sucient stability.
3.2 Mounting aid
Example: PR 6012/32
The auxiliary mounting plate (1) is intended to facilitate installation of the mounting kit
and load cell.

3.3 Internal lift-o protection with integrated jack-up

2 Screw
3 Retaining plate

5 Threaded bush
6 Lower plate
7 Screw (2×)
8 Nut
9 Washer
The mounting kits are equipped with an internal lift-o protection, i.e. no additional
borings apart from the mounting holes in the vessel foot are required.
Moreover, the vessel can be lifted by turning the threaded bolt (4) (see Chapter 3.3.2),
e.g., when inserting the load cell.
The two screws (7) are screwed into the lower plate (6).
The screw (2) is screwed into the upper plate (1) and locked with the nut (8).
That way, the safety clearance "A" can be adjusted (see Chapter 3.3.3).
Maxi FLEX and Maxi FLEXLOCK mounting kits PR 6012/02, ../32, ../42 3 Recommendations for installation
EN-8 Minebea Intec

The threaded bush (5) of the jack-up is cemented rmly into the lower plate (6).
3.3.2 Jack-up
WARNING
The vessel can tip over.
The threaded bolt (4) must only be turned upwards until the recess is visible.
Lift the vessel as follows:
Use the load cell as follows:
1. Loosen the nut (8).
2. Alternately turn the threaded bolt (4) upwards at the hex and turn the screw (2)
downwards to avoid jamming/wedging the upper plate (1).
3. Repeat until the load cell is unloaded and can be removed together with the load
disc.
4. Insert the load disc into the load cell.
5. Insert the load cell into the mounting kit.
6. Load the load cell slowly and adjust the built-in lift-o protection as described in
Chapter 3.3.3.

3.3.3 Adjusting the built-in lift-o protection
1. Alternately turn the threaded bolt (4) downwards at the hex and turn the screw (2)
upwards to avoid jamming/wedging the upper plate (1).
2. Turn the threaded bolt (4) downwards until the load cell is loaded.
3. Turn the screw (2) upwards until the safety distance "A" of 1.5–2.5 mm has been
established between the washer (9) and retaining plate (3).
4. Secure the screw (2) with the nut (8).

3.4 Additional lift-o protection
To increase the permissible lifting force for the mounting kits with constrainer, an
additional lift-o protection can be installed.
PR 6012/53S (M12) is provided for use in PR 6012/02 and PR 6012/32.
PR 6012/54S (M16) is provided for use in PR 6012/42.
For ordering information, see Chapter 8.2.
Assembly:
-Mount the threaded bar (1) so that it has sucient free moving space in the drill hole.
-Lock the nuts (2) so that there is a remaining distance A* from the washer (3).
* A = 2 mm
This distance is essential to avoid force shunts.
The required tightening torques are given in the following table.
