Attention
：
Before using, be sure to read the following sections carefully.
The weighing device has strict payload limit, please be sure to install reasonably; Otherwise,
personal and equipment damage may be caused.The company is not responsible for the loss.
Notice：
In any case, our part is only responsible for the product own quality within the warranty period.
● Declaration：
Due to technological progress, the company reserves the right to change the product; For technical
parameters, please refer to the manual delivered with the product.
Product Appearance, Installing Method and Relevant Structure
● Technical Specifications：
：Intensity exceeding the above listed parameter limits may cause the system abnormality or its permanent damage.
● Main Features：
1.The system is of the structure of sensor with the domination of loading cell and controller, which
can be installed at the car-side rope hitch；
2.Directly outputting full-load or overload signal depending on the change of elevator car payload
；
3. Simple adjustment, high precision of measurement and quick and easy installation.
●
Debugging of weighing device under other circumstances:
If the following reasons occur, it is necessary to re-modify the working parameters of the weighing
device, and the modification method is the same as the above.
