Single Point load cell PR 57 1 Introduction

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 load cells are designed for use in table scales, counting scales, and checkweighers.
The load cells PR 57 may only be used as intended for weighing tasks.
In intrinsically safe circuits, only load cells PR 57/..E may be used.
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 load cells 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 load cell
visually for signs of mechanical damage.
The load cell should not be commissioned if it displays signs of visible damage and/
or is defective.
