Chapter 10 Troubleshooting Symptom Power voltage upper or lower limit error occurs. Only a certain head does not operate. Jump motor does not operate. Wiper motor does not operate. Measures • Is the voltage set on the panel? → If not, set it according to the power supply voltage of the area where the machine is used. • Is the tap voltage in the control box (connector connection) adjusted to the power voltage of the area where the machine is used? → If not, switch the connector connection. • Check the input voltage values in the power/voltage check test mode. Measure the power supply voltage with the tester and compare them. → If the voltage value is significantly out of the normal range (± 5v or more), calibrate it with the voltage calibration in the test mode. • When you cannot enter the test mode because this error frequently occurs, set the voltage to a relatively high value with the machine controller if it is E-D2 and to a relatively low value if it is E-D3 to avoid errors. Check and calibrate the voltage in the test mode. • Check to see the connection of connector P2 of the power supply PCB to connector P10 of the power supply PCB in the control box is proper. • Is the power supply abnormally low because a machine with a large capacity (compressor and the like) is used? → Change the power to the other system. Use a stabilizer. • Replace the power PCB with a new one. Replace the main PCB with a new one. • Is the head out of action with either the head switch or the machine controller? • Refer to the block diagram showing cable connections and check to see that other cables are connected to the head switch PCB and the head PCB and the head PCB properly. • Check to see if connection from the jump motor to connector P11 and P12 of the head PCB is proper. • Check to see if connection from the wiper motor to connector P8 and P9 of the head PCB is proper. • Replace the head PCB with a new one.
