二. “EWD-L-MSJ4-X1”working principle：
With the continuous progress of elevator technology, elevator weighing device on its performance has been
to the point where it can not be ignored. Elevator on the weighing device of high precision, high reliability,
multi-functional needs are imminent. In the sensor technology and micro-computer continues to develop today,
the use of high accuracy sensor to detect the elevator car due to load changes caused by electrical signals.
High accuracy sensor,the use of serial communication technology for its long-distance high-precision
non-destructive transmission; sensor comes with 8 ~ 10m signal transmission cable; at the same time,the
microcontroller is used to carry out scientific calculation and processing,finally, the payload in the cage can be

3.Lift the amount of self-learning process：
After successful completion of the no-load self-learning process,
add 100% of the load weight to the elevator car when the product
"HH-1" is displayed. (For example, this elevator is set to 1000Kg,
The weight of the weight of 1000Kg), press the 【 ■ 】 key to
confirm and save the load data of the car. When the digital
display "1000.0", this time shows the car is the actual load value,
the flag from the self-learning completion.
Digital display of the current load
data, this mark the product from the
successful study, into the normal
working condition.
No
Due to self-learning misuse (elevator load and
weight changes), resulting in digital tube display
weight and car load does not match or the error
is too large, you need to restore the factory
settings, re-self-learning.

Multiplication parameter setting process description (auxiliary function)
）：
Note:Repeated parameter debugging must be in the product after the completion of Chapter 8 product self-learning process before
they take effect. Multiplier parameter adjustment range of "01 ~ 99", that is, the product multiplier for the amount of 1 to 99 times
the amount for customers to choose. The product default multiplier parameter value is 1 times the amount of time to restore the
factory settings after the product multiplier parameters are restored to the product default multiplier parameter value of the rated
load of 1 times.
1.Multiply parameter setting process：
2.for example
：
Has completed the amount of 1000kg self-learning process of the product, into the normal working condition. At this time
digital tube Display "1000.0" for the current car payload value of 1000kg.
According to the above parameter setting process will be multiplied parameter value is set to "bz-05", and successfully saved 5
times
Parameter value. At this point the product light load action load value from the original 1000kg * 5% = 50kg also doubled, this
When the product in the 1000kg * 5 * 5% = 250kg output light load switch signal. And so on, the load signal and
The load value of the overload signal is also increased by 5 times. The output of the product will also be based on the load of the
elevator Suitable for moving car/fixed car bottom elevator
Corresponding to 5 times the value of the analog output changes.
When the system is displayed normally,Press 【 ■ 】 to enter the instruction selection state, and when "00000" is
displayed； press 【 】and【▼】button to change the digital tube display to "00007". "Press 【■】 key to display
"bz - c", press the 【■】 key again to enter the command parameter to modify the state, the product digital hanging
display "bz-01" (after the two digital display "01" That is doubled. For example, when the doubling parameter value is
"05", the frontal load of the elevator doubles 5 times, and the product output switch quantity and analog quantity will
make the corresponding doubling change.) Press the [ ▼ ] key to modify the digital tube display to the required
increment, press the [■] key to confirm and save the doubling parameter.

1. The controller part should be installed in the control box
on the top of the car, and it is best not to be close to the
elevator electronic weighing device transformer, governor
and other equipment. In all cases, sensors and controllers
shall be installed away from heat sources;
2.4 Sensors installed at the bottom of the car, and the
connection between the controller, it is better not to 110V,
220V and other power supply in the same wiring slot;
3. Connect the sensor wiring port to the PG port of the
controller, and connect PV to the power cable according to
the requirements of the weighing device. Be sure to pay
