Why is the motor rotation icon halting on my HO HSING Engine?
If the motor rotation icon in the LCD is halting and not moving on your HO HSING Engine, it may be due to a faulty or poorly connected safety switch, especially in interlock or blind stitch machines. Inspect the safety switch. Also, verify that the parameter setting ?075. SFM? matches the machine head model and safety switch configuration.
What to do if HO HSING Engine displays error ER0. 7?
If your HO HSING Engine displays error code ER0. 7, it could be due to several reasons: * A bad connection at the motor connector. * A synchronizer (sensor) signal error. * The synchronizer is a single position type, and the parameter set wrong type. * The machine is locked, or an object is stuck in the motor pulley. * The sewing material is too thick. Check the motor and its connectors, the synchronizer and its signal, and inspect the machine head for obstructions. Ensure smooth rotation.
What does error ER0. 4 mean on a HO HSING Engine?
If your HO HSING Engine displays error code ER0. 4, it indicates a high voltage issue. This could be due to detecting high voltage when powering on or connecting the wrong, excessively high voltage. Check the AC power supply. If the control box is designed for AC 220V, avoid using AC 380V, as it will trigger the ER0. 4 error. Continuing to supply 380V can damage the electrolytic capacitors (C3, C4) on the main board and cause the power input fuses (F1, F2) to open.
What causes error ER0. 9 on my HO HSING Engine?
If your HO HSING Engine displays error code ER0. 9, it suggests either a shorted machine solenoid or a faulty power transistor on the main board. Inspect the machine's solenoids, ensuring the resistance value is not less than 2 ?. Also, examine all power transistors related to the solenoid.
What does error ER0. 8 mean on a HO HSING Engine?
If your HO HSING Engine displays error code ER0. 8, it indicates a communication error between the operation box and the CPU interface. Please check the Operation Box.
