LF-LA151Instructions for using the type powder detector
LF-LA151The material powder detector is an innovative product developed by Langfeng Electric using imported specialized chips, which is reliable in performance, stable in quality, and easy to install and use,LF-LA151The type powder detector can completely replace imported similar products and is mainly used for detecting various metal or non-metal powders. At present, it is widely used in the production equipment of various ceramic factories (such as tile presses, etc.) to produce ceramic raw materials—The detection of mud powder plays an important role in achieving automation of powder batching and improving product quality.

Product Features:

1StandardDINCard rail installation, easy and fast wiring.
2The power supply adopts a military style fully sealed transformer forAC-DCConversion, good security, strong anti-interference ability.
3Sensitivity adjustment adopts a dedicated imported potentiometer with good dust-proof sealing performance.
4The signal output contacts are selected with high-capacity relays, and the capacity of the contacts can reach10ASuitable for various control requirements.

5All products undergo packaging before being packaged24Power on simulation testing for more than hours to ensure stable quality.

6This product can be used for water level and all machines and equipment that rely on the principle of resistance for detection.

Instructions for Use:

Indicator lights: When the red indicator light is on, it indicates that the working power supply is normal, when the green indicator light is on, it indicates that there is powder, and when the green indicator light is off, it indicates that there is no powder.

Potentiometer: Used for adjusting the sensitivity of powder detection. Clockwise adjustment increases sensitivity; Adjusting counterclockwise reduces sensitivity.

Terminal function introduction:

1：L N Power supply terminal,AC220v(Except for special customization).

2：C1 C2 C3Output relay for status,C1 C2For normally open contacts,C2 C3It is a normally closed contact.

3：A0 A1 Probe terminals.

Common problem handling methods:

1、Why are two powder probes buried in the powder but unable to detect the level signal?

Solution: This is usually due to the low moisture content of the powder. Please try rotating the sensitivity adjustment knob on the operation panel clockwise to increase the detection sensitivity. If the problem cannot be solved, please check if there is an open circuit in the wiring of the probe, or replace it with a known and reliable powder detector to confirm if the powder detector is faulty.

2 Why does the powder drop below the probe, but the detector still detects the level signal?

Solution: This is usually caused by a short circuit at the input end of the powder detector. Please check the insulation condition between the powder probe and the hopper wall to see if there is powder accumulation on the surface of the probe, causing the two probes to short circuit through the material box wall. Please check if there is a short circuit in the wiring of the probe and try to supply power to the detector with an independent power source, or use substitution method to confirm if the powder detector is faulty.
