* do not constrain this position

1 Safety Instructions

The PR 6201 with the relevant mounting kits must be used only for the weighing applications for which it is intended. The dimensions of all mounting and structural components must be calculated so that sufficient overload capacity is ensured for loads which may occur while taking the relevant standards into account. In particular, upright weighing objects (vessel etc.) must be safeguarded against the weighing installation turning over or being shifted, thus eliminating danger to humans, animals or goods even in the case of a break in a load cell or mounting element.

Installation and repair work must be carried out only by qualified personnel.

2 Design Recommendations

2.1 Positioning of Load Cells and Constrainers

The supporting structure of the scale (i.e. the load cell support) and the vessel must be stable enough to withstand the maximum design loads, horizontal (check with spirit level!) and flat. Vessels should preferably be supported by 3 load cells, platforms and weigh bridges by 4 or 6 load cells (see figure).

Parasitic forces, horizontal forces and torques are disturbances which can generate measuring failures and in case of exceeding the specified limits may damage the load cell.

An accurate constraining of the object prevents of damages and measuring errors without affecting the required space for movement. Therefore special attention should be paid to the design, arrangement and condition of the constrainers. Thermal expansion and contractions of the object are to be taken into account which may affect the required space for vertical movement and thus influence the measuring results.

Sartorius EN-3

Compression Load Cell PR 6201 Installation Manual

2.2 Location of Load Cells and Pivots

2.3 Lift-off Protection

For safety reasons, a lift-off protection has to be provided generally in all systems of tank and hopper weighing. It can be realized separately or with the help of mounting kits. The simplest design requires a threaded rod, three nuts, one serrated lock washer and one washer.

2.4 Capacity Selection

The load cell PR 6201 has a high overload capacity due to the fact that the stress in the measuring element is low (1 mV/V). Forces which are exceeding the max. load without damage limit may change the characteristic of the load cell or in the worst case damage the electrical part. If an exceeding of a.m. limit is possible, e.g. falling loads, a mechanical overload protection (limit stop) is strongly recommended.

4 Installation

4.1 General

Caution! All electrical welding at the weighing facility must be finished before mounting the

load cells! Directly when installing the load cell, bypass the load cell with the flexible copper

strap provided for this purpose (see figure), to prevent welding or lightning stroke current from passing through the load cell and damaging it!

In case electrical welding is required subsequently in the neighborhood of the load cell

• disconnect the load cell cable from the measuring instrument,

• bypass the load cell carefully with the above-mentioned flexible copper strap,

• take care that the grounding clamp of the welding set is fitted as closely as

possible to the welding joint in order to prevent a current flow through the load cell.

• Do not lift the load cell on its cable.

• Avoid shock stress (falling down, hard shocks)

• The load cell must be installed so that its axis is vertical.

• The load direction must be as close as possible to measuring axis of the load cell.

• All contact points between load cell and load disc must be adequately greased.

Caution! Changes of temperature >15 K/h may influence the measuring accuracy. To prevent

the load cells from direct heating or cooling effects (sun, wind, heat radiation) heat protection shields or heat protection housings are to be installed if necessary.

all dimensions in mm

To prevent force shunts, all connections of the weighing facility to the surrounding construction (pipes, cables, bellows) must be coupled as flexibly as possible.

Even the best load cells must be handled carefully and installed correctly in order to permanently guarantee good weighing results. It is therefore extremely important to comply with the rules described here!

5.1 General

Caution!

The load cell cable end is protected against contamination and moisture by a protective sheathing.

Remove the protective sheathing only shortly before connecting!

• Protect the cable ends against contamination. No moisture must penetrate into the open cable end.

• Do not shorten the load cell cable. Connect the prepared cable end and roll up the remaining cable.

• The screen of the load cell cable and the screen of the connecting cable must not be connected

electrically inside the junction box, if connection of both ends is not permissible according to the regulations for installation in the explosion-hazarded area.

• The measuring cables should be kept away from power equipment.

• The distance between the measuring cables and the power cables should be at least 1 m.

• The measuring cables should be laid in separate cable conduits or steel pipes.

• Power cables should be crossed at right angles.

6 Preparing for Calibration

Note:

For calibration of the measuring system, please refer to the manual of the weighing instrument.

Caution!

A warming-up time of at least 30 minutes for the load cell is required before calibration of the weighing installation.

6.1 Mechanical Height Adaptation

Before starting calibration it has to be ensured that the load cells are equally loaded. Therefore a height adaptation has to be performed.

• Place the dead load (e.g. empty hopper) on the load cells.

• Energize the load cells by means of a stabilized voltage of e.g. 12 V DC.

• Measure the output voltage of each individual load cell by means of a high-accuracy digital voltmeter and

compare the individual values.

The load cell output with the lowest voltage must be increased by putting shims between mounting plate and weighing construction.

• Lift weighing facility near the load cell.

• Put a thin, deburred sheet of metal (0.5 mm to 2 mm thick) between the upper mounting plate and

weighing construction.

• Measure the output voltage of the load cells again and correct the height of this load cell or another one.

7 Fault finding hints

The following hints will enable a technician for a first diagnostic or help in case of wrong or not reproducible weighing results after commissioning and calibration.

7.1 Visual check

Weighing facility Are all pipes, hoses, and cables connected as flexibly as possible? Are devices which are rigidly connected to the weighing facility in direct

contact with the surrounding installation?

Is there friction between the weighing facility and its surrounding (e.g. dirty

apertures etc.)?

Do the screw connections show a good contact?

Has moisture penetrated the cable end? Mounting kit Is there a contact between lift-off protection and the weighing facility

itself? Are the constrainers stuck? Load cell Does the load cell stand vertically? Is the housing damaged? Is the sheath of the cable damaged? Has moisture penetrated the cable end?

8 Repair/Maintenance

8.1 Repair

Caution! The load cells PR 6201 are designed as robust as possible for the required

measuring accuracy and have a high reliability. In case of an electrical or mechanical defect the load cell must be replaced.

A load cell repair is not possible.

8.2 Maintenance

Load cell PR 6201 needs no maintenance. Pollution on the load cells and on the moveable parts of the weighing installation have to be cleaned in

due time

- if the pollution influences the weighing or

- if the pollution is aggressive against the different materials of the installation. The contact surfaces between load cell and load discs are to be protected by grease. The load cell is

surrounding with off shore all weather protection spray in aggressive pollution.
