七、System debugging methods and instructions (self-learning)：
（Here to lift the amount of 1000Kg as an example to describe the load range setting and "no load and the
amount of two self-learning" process）
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
EWD-L-BMSJ4 intelligent elevator weighing device Manual
Page 2 of 30
exceed the total range of the sensor. Otherwise, the sensor will be damaged and the product will not be used.
1.Elevation range setting
：
Note
：①
1. Product digital tube display the default decimal point to
1, the unit is Kg, For example :the case shows "1000.0", that is 1000kg.
2.No-load self-learninocess
：
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
1.Check that the sensor wiring is correct;
2. Confirm the signal grade and polarity of the product terminals,
and after the plug is firmly connected, the product is powered on
and the digital tube is displayed normally。

car at this time。保 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.
yes
NO

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：：
1
Double-click the quick recovery method：Turn on the power，
press same time【 】and 【▼】10slater，when show“

【 】and 【▼】Change the digital tube display to“
00006
”，
press【■】enter“help-”，press again【■】，to restore the
factory settings.

八、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
：
When the system is normally displayed, press the " ■ " key to enter the command selection state. When
"00000" is displayed, press the "【】 key and [▼] to modify the display of the nixie tube to" 00007 ". Press the "
■" key, and when "BZ--C" is displayed, press the "■" key again to enter the command parameter modification
state. Product digital display "BZ-01" (the last two digital tube display "01" is the multiplier multiple, such as the
multiplier parameter value of "05", at this time the elevator load multiplied 5 times, product output switch quantity
and analog quantity will make the corresponding doubling changes) press [▼] the key to modify the digital tube
display to the required times value-added, Press ■ to confirm and save the multiplication parameter.
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
