Before the system debugging：
①：Products must be in strict accordance with the "EWD-L-MSJ4 user manual" for self-learning,
otherwise it will cause the product can not be used and product measurement accuracy is not
accurate.
②：Before commissioning, it is necessary to specify the weight of the car. The weight of the truck
can not exceed the total range of the sensor. Otherwise, the sensor will be damaged and the product
will not be used.

2.No-load self-learning process：
Note
：①
product no-load self-learning before the car must ensure that there is no load and debris,
otherwise it will lead to a greater error in the weighing effect.
② product no-load - the two-point self-learning process, must be "LL-01" first study
no-load, "HH - 1" retraining, otherwise it will lead to the product can not be used
Contact power supply，press【■】Enter the command selection state，

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.
Has been successfully
completed the elevator rated
load range set, the elevator
car weight and rated load no
longer change.
Yes
No
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.

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：：
Double-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。
Instruction parameter confirmation method：Turn on the power，
press【■】，enter“00000”Command selection interface，press

8、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.
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,

Precautions for installing controllers and sensors
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 attention to the voltage level;
4. Power on the weighing device after the check is correct, and the
controller should be displayed in the corresponding working
mode. the corresponding working mode.
