1. Fault judgment
When the electronic scale presents the following phenomena, it is necessary to see whether the load cell presents a problem.
1) If the electronic scale does not show zero, the display screen continues to shine or show zero in the future, and the weighing number does not appear when weighing.
2) When the electronic scale is unloaded or loaded, the displayed number is unstable, drifting or jumping.
3) The weighing of the electronic scale is not accurate, and the weighing number displayed is inconsistent with the number of weights added.
4) The repeatability of the electronic scale is not good, and the same weight is added, sometimes the weighing is accurate, and sometimes the weighing is inaccurate.
2. How to replace
Once a load cell is faulty, it needs to be replaced, which can be done by following these steps:
1) Open the cover plate above the sensor, jack up the weighing platform with a jack, and remove the ground wire of the sensor.
2) Flip open the junction box and get rid of the damaged sensor cable from the junction box. Pull out the cable at the sensor end. Note: When drawing the cable, attach a lead wire through the scale body so that when the sensor is replaced, the cable can pass through the scale body and enter the junction box.
3) Thread the sensor cable through the scale body into the junction box.
4) According to the wiring diagram, fix each core of the cable on the corresponding binding post of the junction box.
5) Loosen the jack, lay flat on the weighing platform, and cover the cover.
6) After the sensor is replaced, the scale must be reset and calibrated.
7) After the sensor is installed, its excess cables should be bundled and placed not directly on the ground.
8) In order to ensure the consistency and interchangeability of the sensor, the sensor cable shall not be cut at will.
9) During the installation and disassembly, the sensor should not be scratched or bumped, and the cable should be protected.

Precautions during the installation of safety barriers
1. The safety barrier should be installed in a safe place, and the environmental conditions meet the requirements of the "application conditions" in the "Safety Gate Selection Sample".
2. The connecting wires of the intrinsically safe end (blue end) and non-intrinsically safe end circuits of the barrier safety barrier should be laid separately in the wiring slot.

Features and functions of photoelectric switches of the sensor
Photoelectric switches are what we generally call sensors. The national standard GB7665-87 defines the definition of the sensor: a device or device that can sense the measured part of the rule and convert it into a usable signal according to the certain rules, which is generally composed of a sensitive element and a conversion element.

Sensor Selection Considerations – Benefit Us
In order to carry out a detailed measurement operation, it is necessary to first consider the principle of the sensor, which needs to be determined after analyzing many factors. Since, even if the same physical quantity is measured, there are multiple principles of sensors to choose from, which principle of sensor is more suitable, ...

Application features of rotary incremental encoders
The rotary incremental encoder outputs pulses when it rotates, knows its orientation by the counting device, and remembers the orientation by relying on the internal memory of the counting device when the encoder does not move or the power goes out. In this way, when the power goes out, the encoder can not have any movement, and when the call is working, the encoder ...

P+F proximity switch selection points
1. Select the proximity switch type according to the detected object. If the detection object is metal, the inductive proximity switch is preferred, and if the detection object is a non-metal such as wood, plastic, paper, water, etc., or a smaller and finer metal, a capacitive proximity switch should be selected.
