Remedy: 1. Check the assembly position of linear scale and encoder PCB assy. 2. Check linear scale (scratches or dirtiness or so.) 3. Replace the linear scale with a new one. 4. Replace the encoder PCB assy. with a new one.
Code: 511
Display: ERROR 511 Z ORIGIN
Description: Z-origin error (Origin of Z-axis can not be detected)
Remedy: 1. Execute and confirm [#TEST SENSOR TEST]-> [Z-ORG]. 2. Check the connector connection of Z-origin sensor. 3. Replace the Z-origin sensor with a new one. 4. Check the assembly and connector connection of Zaxis motor. 5. Replace the Z-axis motor with a new one. 6. Replace the HDC2 PCB with a new one. 7. Replace the main PCB with a new one.
Code: 519
Display: ERROR 519 NEGATIVE P.SENSOR
Description: An error of the negative pressure sensor has been detected.
Remedy: 1. From [#TEST AGEING] -> [AIR PUMP] -> [: NegativePressure], check whether the pressure value at SPEED [0] and VALVE [__] is around ± 0 kPa. 2. Replace the negative pressure sensor PCB with a new one.
Code: 51a
Display: ERROR 51a POSITIVE P.SENSOR
Description: An error of the positive pressure sensor has been detected.
Remedy: 1. From [#TEST AGEING] -> [AIR PUMP] -> [: NegativePressure], check whether the pressure value at SPEED [0] and VALVE [__] is around ± 0 kPa. 2. Replace the positive pressure sensor PCB with a new one.
