In order to make the electronic belt scale better play its excellent performance, reduce the occurrence of faults, often to its maintenance and debugging is necessary, xuzhou sanyuan automation technology co., ltd. for you to sort out the relevant information, hope to provide you with some help.

Environmental protection of metering conveyor and scale area

Conveyor should as far as possible in indoor, for outdoor conveyor, at least at the site of the installation of belt scale, and take the corresponding measures from the rain, open-air belt scale is difficult to ensure the accuracy of measuring the length of the weather for scale area before and after for at least 12 m, the height of the weather facilities, from the date the conveyor frame foundation surface, at least 1.7 m above.

Maintenance of belt weigher parts

To regularly remove the scale area dust, material block, especially the lever, scale area idler, measuring drum on the material to often clean;

Symmetrical heavy idlers are lubricated regularly, at least twice a year, and reset to zero after lubrication;

Always keep the belt running along the center line of the conveyor. If the belt is out of tolerance due to material deviation, the feeding mechanism must be adjusted.

Weighing rack to prevent overload, impact, strictly prohibited in the weighing rack station, when conditions can be protected;

Check the contact between the measuring drum and the belt regularly, and deal with the slippage or the dip in time.

Adjust the balance of 17A/B belt scale

17A/B belt scale used for a period of time, generally 2 to 4 months should check the sensor output balance, the sensor balance changes are caused by: belt deviation; The conveying frame material strength is not enough and the rigidity is poor; Scale mounting problem.

Methods to adjust balance:

Turn off the meter power

Remove two wires of the sensor output signal (two wires do not move)

Feed meter power

Measure the output voltage of the two weight sensors separately. If they are different, adjust the nut under the boom to make the output consistent.

Tighten the nut, measure again and adjust if there is a change. We need to reset the balance.

Instrument maintenance

Wipe the meter case clean with a clean damp cloth;

Use a cold air blower to blow off the dust inside the instrument;

Visually inspect all wiring, connectors and integrated circuit connectors of the instrument.

The instrument should be far away from the strong electric field, strong magnetic field and strong pulse source as far as possible, and there are dust prevention measures in the machine room to ensure that the electronic circuit of the instrument works in a clean air environment, to prevent the static interference of dust.

Prevent damage to belt balance by lightning strike

Lightning strikes can cause damage to a variety of devices inside the weighing sensor and instrument. For frequent lightning areas, especially in the rainy season, pay more attention to belt scale protection. The main methods are: the power supply grounding quality is good; In the weather where lightning and thunder may occur, the power of the instrument can be turned off if allowed. Increase necessary lightning protection equipment; With certain spare parts.
