Common faults and maintenance methods of UVLED curing machines

During the operation of the UVLed Curing machine, various faults may occur due to improper operation, aging of accessories or environmental factors. The following is a comprehensive summary of common faults and their repair methods:

1. The LED beads do not light up or self-extinguish
1. Cause of the malfunction
Aging of LED beads: Long-term use leads to the attenuation of UVLED LED beads.
Poor heat dissipation: Dust accumulation on the fan or insufficient air cooling leads to overheat protection.
Power supply issue: Low voltage or poor contact of the power cord.
Abnormal connection: Loose cable or abnormal power supply of the power cable.

2. Solution
Replace the aged lamp beads (contact the technical support of the manufacturer).
Clean the dust from the fans and heat dissipation channels to ensure the normal operation of the air-cooling system.
Check the power supply voltage. If necessary, configure a voltage stabilizer or replace the power cord.
Reinsert and tighten the cable connection.

Second, the equipment temperature is too high
1. Cause of the malfunction
Cooling system failure: Fan stops rotating or the cooling channel is blocked.
High-load operation: Staying in a high-intensity light exposure mode for a long time.
High ambient temperature: The working environment is not equipped with air conditioning or ventilation facilities.

2. Solution
Check the operating status of the fan, clean the accumulated dust and carry out regular maintenance.
Optimize the usage mode to avoid long-term high-load operation; Upgrade to a water-cooLed UvLED curing machine when necessary.
Improve the ventilation conditions of the working environment or add air conditioning equipment.

Three. The controller fails to start up or the entire machine runs out of power
1. Cause of the malfunction
Power supply issues: Loose power cord, blown fuse or poor socket contact.
Circuit protection trigger: The air switch trips or the time relay setting exceeds the limit.

2. Solution
Check the 220V power connection and replace the blown fuse (the spare fuse is usually located in the socket).
Make sure that the power socket is not blackened or the pins are loose. Replace the socket if necessary.
Check whether the capacity of the air switch matches and adjust the Settings of the time relay.

Iv. Alarm Anomalies (such as ERR-TS, ERR-LED, etc.)
Common alarm codes and their causes
ERR-TS: Loose cables or incorrect channel Settings (such as in a one-to-two model, the channel is mistakenly turned on and not connected).
ERR-LED: Failure of a single LED bead or abnormal power supply.
ERR-OT: Poor heat dissipation triggers overheat protection.

2. Solution
Check if the cable connection is firm. Reinsert or replace the cable.
Replace the faulty light beads or check whether the power output is stable.
Clean the heat dissipation system and optimize the working environment temperature.

Five. The UV lamp will automatically go out
1. Cause of the malfunction
Thermal protection triggered: transformer overheating or exhaust motor failure.
Component aging: Thermistor damage or expiration of the lamp tube's lifespan.

2. Solution
Check the temperature of the transformer, clean the dust and improve the ventilation.
Replace the damaged thermistors or aged lamp tubes.

Vi. Maintenance Suggestions
Regular cleaning: Focus on cleaning the fan, heat dissipation channels and cable interfaces to prevent dust accumulation and oxidation.
2. Environmental control: Keep the working environment dry and well-ventilated, and avoid high-temperature and high-humidity environments.
3. Power management: Use a voltage stabilizer to ensure stable voltage and avoid frequent plugging and unplugging of power cords.
4. Professional support: When it comes to replacing LED beads or repairing circuits, it is recommended to contact the technical personnel of the manufacturer for handling.
