Basic Troubleshooting (1). Error Code And Measurement - Siruba C007K Manual

7. Basic Troubleshooting :
(1). Error Code and Measurement:
Error Code
1. When power on, detected high voltage
ER0. 4
2. Connect the wrong voltage, too high.
1. Bad connection at the motor connector.
2. Synchronizer (sensor) signal error.
ER0. 7
3. Synchronizer is a single position type, and parameter set wrong type.
4. Machine locked or object stuck in the motor pulley.
5. Sewing material is too thick.
ER0. 8
Operation Box linked to CPU interface had communication error
1. Machine solenoid shorted.
ER0. 9
2. Main board's power transistor is faulty.
1. If parameter 【121.ANU】 is set ON, but Auto Needle Up is malfunction
ER0. 11
when the power turned on.
2. Machine locked or motor pulley have object stuck in it.
Motor rotation icon in LCD is halting and not moving.
1. Safety switch is either faulty or bad connection. (For interlock stitch or
.
blind stitch machine).
2. Parameter【075. SFM】setting not match the machine head model.
Cause of The Problem Status and Measurement
Motor and machine will be shutting down.
Please check the AC power. (Too high)
＊If control box is AC 220V system, don't use the AC 380V power voltage,
otherwise the LED will display ER0. 4 after 2 second of power ON. If continue
supply the 380V power, the electrolytic capacitors (C3,C4) of main board will
burst open over a period of time and cause the fuses (F1,F2) of power input
open circuit.
Please check the main pc board.
Motor and machine will be shutting down.
Please check the motor or motor connectors' connection.
Please check the Synchronizer (sensor) and its signal.
Please check machine head to see if objects stuck in the motor pulley, or rotate not smoothly.
Motor and machine will be shutting down.
Please check the Operation Box.
Motor still can run, but all output signals and Operation box's pattern sewing function will be invalid..
Please check machine's solenoids or the resistance value is 2 Ω less.
Please check all the power transistors which related to solenoid.
Motor still can run, but it automatic starts the clutch mode. All Constant-stitch sewing pattern and
trimmer wiper function will be invalid.
Please check Synchronizer's up position's signal.
Please check main board's Synchronizer circuitry.
Please check machine head to see if objects stuck in motor pulley, or rotate not smoothly.
Motor stops.
Please check the safety switch.
Please check parameter table on【075. SFM】 setting, make sure it match machine head
safety switch
