System overview
一
.
“EWD-L-MSTJ4”The main features of the weighing device:
1. When the product is working normally, the internal payload of the cage can be directly displayed. The self-study
process is simple to operate.
2. Intelligent programming and control process, according to different customer needs, can adjust the percentage of
load corresponding to any of the 4-way switch signals output by the controller and the output of turn-off/turn-off, and
modify the output mode of analog quantities.
3. Intelligent sensor: choose high-precision XCL-YL-C tension sensor to directly detect the change of load of the car;
4. Wide measurement range (the payload can be set manually according to the demand), high positioning accuracy and
intelligent temperature compensation.
5. The electrical performance conforms to the standard requirements of "international electrotechnical commission
(IEC)";
6. The core is composed of a high-precision load sensor and a high-performance monolithic microcomputer.All
working parameters can be set on site.
7. Output full-load and overload signals directly according to the change of cage payload;.
8. With the ability of manual fine-tuning correction of working parameters, the error of elevator after decoration can be
manually corrected to achieve the purpose of accurate measurement.
9. Unique sensor + controller design structure, simple wiring.
10. From the perspective of the user, it is easy to install and debug, reduce the additional cost in the user's use, and the
performance price is higher.
二. “EWD-L-MSTJ4”working principle：
With the development of elevator technology, the influence of elevator weighing device on its performance
cannot be ignored.The elevator is in urgent need of high precision, high reliability and multifunction of weighing
device.With the continuous development of sensor technology and microcomputer, a high-precision c-type 25Kg
sensor is used to detect the electrical signals generated by the elevator cage due to the change of load.High precision

2.Elevator no-load self-learning process：
Attention:①Before the no-load self-learning of the product, there must be no load and debris in the car,
otherwise it will lead to a large error in the weighing effect.
② Product no-load - load two points self-learning process, must be "LL-01" to learn no-load, "HH--1" and then load,
otherwise it will lead to the product can not be used.
Yes
Has been successfully completed the
elevator rated load range set, the elevator
car weight and rated load no longer
change。
Yes
Elevator due to late decoration, car
weight has changed, or because the
customer needs to modify the rated
load.
Follow the first step to complete the elevator scale
setting operation.

the command parameter modification state ，when
show “LL-01”，In the car when no load，press【■】
to confirm and save the load data of the empty car
at this time。Save success show "HH - 1", thus no
longer successful learning.

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.
Restore factory default method：
①Double-click the quick recovery method：Turn on the
power，press same time【 】and 【▼】10slater，when
show“HELP-”，The internal setting has been restored
to the factory settings。
②Instruction parameter confirmation method：Turn on
the power，press【■】，enter“00000”Command selection

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,Corresponding to 5 times the value of the analog output changes.
