EWD-L-CAN/M2 Elevator Load Weighing Device introdtion manual V2.2
Notice: In any case, we are only responsible for the quality of the products during the warranty period.
Description:
1. The indicator on the upper left corner of the digital tube is the working status indicator, and has no other
meaning;
2. 2. The nixie tube and button functions are disabled. After power-on, the nixie tube is not displayed normally
● Pruducts apperacne diagram
Note: All wiring ports are strictly prohibited from plugging and unplugging; Do not connect the power cord to the CAN
communication port (port P/N), otherwise the device will be damaged immediately!
●Technical Specification:
⒈
Application
Suitable for all traction, hydraulic, strong drive elevator weighing use (load range depends on the
sensor range).
⒉
Sensitivity
Elevator rated load weight/200 (when rated load 1T the weight is 5.0kg) [This indicator will be
affected by the mechanical properties of the elevator]
⒊
System Error
≤1.5％(-20～55℃)

2.1 Sensor size diagram
Note: ø6 wire rope must be used to connect the safety ring and secure it on the support of the traction
machine to prevent the sensor from falling off during the installation and commissioning of the elevator to
ensure personal safety
2.2 Installation Method
：
Weighing device debugging method：
Step
Project
Specific operation
First step
Study
praperation
1. After the controller and sensor are correctly installed and checked, the elevator is
stopped at the bottom floor and the car is placed in the empty load.
2. After the weighing device is powered on and connected to the weighing device
through the tablet computer, check whether the AD value CAN be communicated with
the weighing device;
(If no or the data is wrong, check whether the sensor connection is good and the ground
cable is firmly grounded)
Second step
"No-load"
self-learning
1. Go to the menu bar of "Weighing Self-learning" in the tablet computer
2. Send no-load self-learning instructions, and the weighing device remembers the
no-load data.

Third step
"Rated-load"
self-learning
1. Load the weight of the elevator to 100% of the load, such as the load of 1000kg
elevator, add 1000kg weight in the car.
2. Through the tablet computer, send the load self-learning instruction, and the
weighing device remembers the load data.
3. After learning is completed, the weighing will enter the normal working state
※note：1.The power supply voltage level must meet the requirements, and ultra-high voltage will cause damage to the
weighing device;
2.CAN-BusThe sequence of signal lines, connected in reverse, may cause self-learning failure.
Promise:
1. The weighing device in the factory within one year of the product quality problems, free replacement
(product seal damage will not be accepted).
2. If the weighing device is abnormal during commissioning or use, please contact us directly
