Load weighing device of EWD-RLG-SJ3 controller and EWD- GD load sensor
This system can be adopted to all kinds of fixed car 2:1 traction
drive elevator with three-way programmable switch output.
Main features:
1. Equipped with variety of intelligent sensors: A. Ultrathin “disc” type load sensor to direct detect the changes of the car load, there is no need to change the traction taper sleeve rod；B. Choosing the character B intelligent tension sensor with easier installation；C. The convex stress intelligent sensor is specially suitable for elevator manufacturer. D. Adopting the character D load sensor.
2. All operating parameters can be set at the spot.
3. The unique programmable output signal control method can meet the the requirements of the weighing signal of varieties of fixed car platform.
4. It is easy to operate the self-learning model at the spot. The user can choose 20~100% rated self-learning model or rated set model(for type “A”), quite easy to operate.
5. With the ability to amend the working parameters automatically and
self-adoption intelligent landing compensation.

| 9. | Relative Humidity | 20%-90%RH | ||
| 10. | Reaction Time | ≦0.5 Second, The communication distance between the intelligent and control is 0-400m. | ||
| 11. | Power Supply | AC/DC24(±10%)V/200mA | ||
| 12. | Installation place | Sensor section: A the place of traction rope shackle Controller section: control Cabinet in machine-room. See the figure 3 for installing dimension. | ||
| 13. | Overall size | Sensor section: see figure[3]: controller section: 115×90×40mm3 | ||
Description of the System Controller Terminals:
Working principle and installation method:
With the adoption of highly accurate intelligent ”tension” or ”load” and “stress” sensors, the electric signal produced by elevator car load changing is tested and inspected. System sensor installed at the traction rope hitch: Type “EWD-LG-SJ3”:With the adoption of serial communication technology, the signal can be transmitted remotely,
highly accurately without loss.；Type “EWD-RLG-SJ3”:There is an 8-meter-long signal transmitting cable with the sensor. And the single-chip built-in the controller may do scientific calculations fulfilling the aim of weighing the effective load in elevator car.

The multi-level mine design, mine components imported original, can withstand 10 million times 5000A surge current. Especially for frequent thunderstorms regions. 2. Dual transformer design, make the product last longer (usually uncharged amplifier), while saving energy. 3. Special anti-jamming technology to effectively prevent noise. All kinds of protection: short circuit, thermal protection, high pressure protection. Third,Function 1. 1. arbitrarily adjust the frequency, volume, address code, group code, switch control software and remote control. 2. Preventing illegal signal insertion. |

| 3 | Process | 1.Water treatment. | 1, Waterproof, moisture, corrosion, mildew treatment. |
| 4 | System design costs | Integrated circuit board design. Failure need professionals to the scene investigation, is not suitable for large area. High installation and maintenance costs. | 1, modular structure, the amplifier board, decoders, receiver plates without electric iron to replace the circuit board when servicing. 2, each circuit all with self-test function, you can always see if the device is working properly. In everyday use, greatly reduce the amount of maintenance. 3, each of the circuit boards are highly integrated multilayer design. Notes: Industrial equipment at the time of the purchase cost is slightly higher, but long-term use period advantage gradually revealed, especially in rural areas do not know more advantages for the use of professional and technical personnel. Because each product is an intuitive instrument. |
