1.2.2.1. Part Non-placement Error

E0300 Parts are blown because the vacuum pressure became low due to a defective

component of the head’s pneumatic system.Parts are blown because the vacuum

pressure became low due to a defective component of the head’s pneumatic system.

[Cause]

1) Defective solenoid valve

2) Defective Vacuum Pump (Applied only to the SM471, 481, DECAN F2

machine)

[Measures]

1) Perform solenoid valve operation test. If a problem occurs, contact or our local agent.

(Replace the solenoid valve.)

2) Check whether the vacuum level of the front vacuum gauge is -90kPa. If a problem

occurs, contact or our local agent. (Replace the Vacuum Pump.)

E0301 User parameter setup error (part thickness, illumination brightness, etc.)

[Cause]

1) Part transfer speed was set incorrectly

2) Part thickness was set incorrectly

3) The nozzle end does not come into contact with the upper surface of the PCB when the

spindle is moved down to the level at which the Z-axis height is '0' (zero)

[Measures]

1) Find and set the speed suitable for the corresponding part manually while changing

the part transfer speed little by little.

2) Lower the Z-axis to the placement height manually and set the height correctly.

3) Calibrate the Z-axis offset again referring to the Administrator's Guide.

E0302 Excessive fluctuation range of main pneumatic pressure (4.5 Mpa ~5.5 Mpa)

[Cause]

1) Incorrect setup of the main air regulator (0.45 Mpa ~0.55Mpa)

2) Large amount of moisture has entered the air pipes

3) Defective air compressor

[Measures]

1) Check whether the main air regulator gauge has any problems and replace it if

necessary. (Replace Air Regulator )

2) Check the air line. If it has too much moisture, clean it.

3) If the air compressor operates abnormally, replace it. Air Compressor

System Messages of the MMI and Solutions

E0303 Parts are blown in a certain machine model

[Cause]

 Unstable blow pressure

[Measures]

 Supply a stable blow pressure by separating the screen printer and blow pressure.

(Blow Gauge 1.0 Bar) (Blow Gage 1.0 Bar)

E0304 Abnormal vacuum was generated due to a defective connection cable of the vacuum

solenoid valve

[Cause]

 The solenoid valve power supply cable is not connected properly

[Measures]

 Check whether the solenoid valve power supply cable is connected properly. If it has a

problem, contact our designated C/S company or local agent. (Replace the head

vacuum solenoid power supply cable)

E0305 The Z-axis height of the placement point becomes incorrect due to a PCB clamp setup

error

[Cause]

 The nozzle end does not come into contact with the upper surface of the PCB when the

spindle is moved down to the level at which the Z-axis height is '0'(zero)

[Measures]

 Contact our designated C/S company or local agent. (Adjust the PCB clamp)

E0306 Parts are blown since the blow pressure is excessively high

[Cause]

 Blow pressure becomes excessively high due to incorrect setup of the blow solenoid

valve

[Measures]

 The solenoid setup value is different depending on the machine. Regarding the

method to control the solenoid valve, contact our designated C/S company or local

agent.

 SM411/ 421/ 411F/482/168

Adjust the regulator pressure so that the blow set pressure becomes -60 ~ -100

mmHg

 SM471/481/DECAN F2

Adjust the needle valve of the manifold so that the regulator pressure becomes -50

~ -70 mmHg

1-30

Next Generation, Multi-Functional Placer DECAN S1 Troubleshooting Guide

When the regulator pressure is 0.1Mpa, adjust the needle valve of the manifold so

that the blow set value becomes -40 ~ -60 mmHg.

E0310 A PCB warps up and down

[Cause]

 The placement height has deviated as the PCB has warped downwards.

 The part bounces out since the PCB is warped upward.

[Measures]

 Check the flatness of the PCB using a 'ruler' with the PCB fixed. Replace the PCB

causing the problem.

E0320 A part adheres to the nozzle since the blow pressure is excessively low

[Cause]

 Blow pressure becomes excessively low due to incorrect setup of the blow solenoid

valve

[Measures]

 Control the blow solenoid valve so that the lower limit value of blow becomes -

50mmHg when the regulator pressure is 0.06Mpa. Regarding the method to control

the solenoid valve, contact our designated C/S company or local agent.

E0321 A part drops since the vacuum pressure is low due to a fouled vacuum filter

[Cause]

 The generation of blow and vacuum pressure is delayed due to a fouled filter

[Measures]

 Check the filter for discoloration. If it has a problem, replace the vacuum filter. (The

vacuum filter is a consumable part, replace it every 6 months)

E0322 Air leaks from the vacuum filter since its case was assembled incorrectly or damaged

[Cause]

 Filter case was damaged

[Measures]

 Replace the head vacuum filter case.

E0323 A part adheres to the nozzle since the blow pressure becomes low due to a defective

solenoid valve

[Cause]

 Defective solenoid valve

[Measures]
