Fault phenomenonFault causeSolution
Ejector leakageDust inside the ejectorCyclic test of the ejector
ejector has been damagedReplace ejector
Ejector fails to operate.Poor contact between the plug behind ejector 
and the socket
Re-plug, repair the poor contact position
Disconnection occurred to the valve coreReplace the ejector
Color sort board has been damagedReplace color sort board
Ejector with small spray
volume
Dust inside the ejectorCyclic high frequency test of the ejector
Low air pressureCheck pressure gauge and relevant air circuit
Material flyingBig difference in temperature between the 
material and the material chute
Adjust temperature of the chute to approximate that of the material.
Dust agglomerationClean the chute with soft cloth
Chute with scratchSand papering or replace it
Frequent operation for solenoid valveWrong ejectorCorrectly select sort mode
Position of background plate not properly setReadjust background plate
No color separationLow sensitivityReadjust sensitivity
haven't been power onPower on the solenoid valve power supply
Poor Color Separation EffectDust on the sorting glassRemove dust manually or by soft cloth
Incomplete for the color sorterCheck or replace rubber strip
Poor Separation Effect of 
Complete Machine Side
Incomplete or poor ash removing for the rodless cylinderAdjust ash wiper and the ash wiping speed
Color sorter stops working 
frequently
High sensitivityReadjust the sensitivity
Improper adjustment of background plateReadjust the background plate
Raw material with high quantity of impurityReduce the yield
Color sorter is under pressureCheck pressure; readjust if the gas circuit is too far away from the sorter
Frequent pressure protectionClean and open the pipeline by cleaning or replacing the filter element
Motor three-phase winding is damagedReplace the motor
A.C. contactor damaged or poor contactMaintain or replace A.C. Contactor
Thermorelay damaged or poor contactMaintain or replace thermorelay
380V power supply phase shortageMaintain charging line
Three-phase voltage imbalanceAdjust transformer to achieve three-phase voltage 
balance
Control switch circuit damaged or with 
problem
Check the control switch and circuit
