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 6041/30, PR 6041/40 are intended for weighing tasks, and must
only be used as such.
The mounting kits PR 6041/30, PR 6041/40 are designed for installing the load
cells PR 6241.
The dimensions of all mounting and structural components must be calculated so that
sufficient 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/qualified personnel.
The mounting kits reflect 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 filed with the carrier immediately. The
Minebea Intec sales or service organization must also be notified.
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
3 Recommendations for installation Mounting kits PR 6041/30, PR 6041/40
Minebea Intec EN-5

-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 sufficient stability.
3.2 Mounting aid
Example: PR 6041/30
The auxiliary mounting plate (1) is intended to facilitate installation of the mounting kit
and load cell.

3.3 Additional lift-off protection
For safety reasons, a lift-off protection has to be generally provided on vessels.
For this purpose, the simplest version requires the following components:
-1× threaded bar (1)
-3× nut (2)
-1× washer (3)
Assembly:
-Mount the threaded bar (1) so that it has sufficient free moving space in the drill hole.
-Lock the nuts (2) so that there is a remaining distance A* from the washer (3).
* A = 1–2 mm
This distance is essential to avoid force shunts.
The required tightening torques are given in the following table.

5 Installation
5.1 Prior to mounting
5.1.1 Preparing the foundation/substructure
-The foundation for the mounting kit must be horizontal (use spirit level), flat, and
rigid for the intended loads.
-The load distribution on the available load cells must be as even as possible to
prevent overload of the individual load cells.
-The substructure foundations/supporting surfaces for the mounting kits should be at
the same level, and the supporting surfaces of the weighing object (e.g. vessel feet)
must be arranged in parallel.
- For screw mounting of the upper and lower plates:
-Generate the drilling pattern of the upper plate of the mounting kit (see
Chapter 4.2) according to the weighing system arrangement for each vessel lug
or vessel foot.
-If soft filler layers (e.g. made from rubber or plastic material) are used between the
mounting kit and vessel/or between the mounting kit and substructure for vibration
dampening or for temperature insulation, a load compensating plate must be
provided between this soft filler layer and the mounting kit to ensure even load
application into the mounting kit.
The design of the insulation and compensation plates depends on the respective
application.
The maximum permissible inclination must be strictly observed in order to keep the
impact on the measuring accuracy to a minimum (see figure).

5.3 Assembly
5.3.1 Safety instructions
WARNING
The vessel may turn over during mounting.
Securing the vessel against tipping is imperative.
Use an appropriate lifting jack.
NOTICE
Welding or lightning strike current flowing through the cell can damage it.
All electrical welding on the weighing system must be finished before mounting the load
cells.
When installing the load cell, immediately bypass the load cell with a flexible copper
strap (included in the load cell equipment).
Mounting kits PR 6041/30, PR 6041/40 5 Installation
EN-12 Minebea Intec

During any additional electrical welding work near the load cell:
-Disconnect the load cell cables.
-Bypass the load cell using the flexible copper strap.
-Make sure that the grounding clamp of the welding set is fitted as closely as possible
to the welding joint.
5.3.2 Installing the mounting kit and inserting the load cell
Note:
Screw mounting of the upper and lower plates is described below.
The operations must be performed at all supporting points (e.g., vessel) of the weighing
object.
Requirements:
All threaded holes for the upper plate are available in the vessel lug/vessel foot (see
Chapter 4.2).
Procedure:
Example: PR 6041/30
1. Fit the mounting kit to the vessel foot (2). It is essential to observe the property
classes and tightening torques of the screws (4) and washers (5) (refer to Chapter 5.2).
5 Installation Mounting kits PR 6041/30, PR 6041/40
Minebea Intec EN-13

Note:
If required, the threaded bar, washers, and nuts can be mounted as additional lift-
off protection (see Chapter 3.3).
CAUTION
Do not damage the membrane at the load cell side.
Carefully insert the load cell.
The load cell must be seated centrally between the pins.
* PR 6041/30: O-ring, PR 6041/40: silicone ring
2. Place the vessel and mounting kit in the required position on the foundation/
substructure (7). Always make sure that the plates are parallel and seated vertically
above each other.
3. Mark mounting holes for the lower plate (6).
4. Position the vessel with the mounting kit so that the drilling can be performed.
5. Secure the mounting kit to the foundation/substructure (7). Make sure to use the
correct tightening torques (see Chapter 5.2).
6. Connect an equipotential bonding conductor (1) (not included) between the upper
plate (3) and the lower plate (6).
7. Once all welding near the load cell and mounting work on the weighing object is
complete, clean the recess for the load disc (10) in the upper plate (3) and the recess
for the load plate (9) in the lower plate (6).
8. Position the lifting gear on the weighing object.
9. Remove the auxiliary mounting plate (12).
10. Remove the spacer (see Chapter 4.1).
11. Insert load plate (9) into the lower plate (6).
12. Use appropriate lifting gear to lift the weighing object so that the load cell (11) can be
positioned vertically with the two load discs in the mounting kit using the supporting
ring (8)*.
13. Load the load cell slowly. It is essential to ensure that the load cell is vertical and not
jammed after loading.
14. If necessary, re-adjust the upper plate (3) and the lower plate (6).
15. If necessary, adjust the additional lift-off protection (see Chapter 3.3).

5.4 Check mounting
When all mounting kits have been installed, check them for proper mounting.
In particular, force shunts should be avoided.
It is essential to check:
-whether the auxiliary mounting plate has been removed.
-whether the load cell has been inserted in the mounting kit vertically and without
being canted.
-whether the upper and lower plates are mounted in a horizontal position.
-whether free moving space and the required play for thermal expansion are provided.
To avoid force shunts, all incoming and outgoing lines (hoses, pipes, cables) must be
connected to the measured object with the greatest flexibility possible.
The entire load must be supported by the load cells!

6 Cleaning
The mounting kit is easy to clean. It can be spray-washed with water.
For this purpose, spray the water jet from top to bottom and around the mounting kit.
NOTICE
Some cleaning agents may not be compatible with the mounting kit material.
When using cleaning agents, ensure that their compatibility with the mounting kit
material has been tested and approved (see Chapter 4.3).
