Checkpoint 8 FINAL CHECK
The Hot Quickcoder should now be working properly.
If the HQC is still not working properly, the Korthofah service department should be called.
(*) If some time has passed after Checkpoint 4, the control light should flash for at least five minutes.
During this period, the entire text head on the Hot Quickcoder reaches the desired temperature which
is essential for further tests.
Checkpoints: steps to be carried out
1. Press the OFF button and disconnect the system from the mains by removing the mains cord from
the control box.
2. Check whether the wires from the mains connection are fastened properly in the plug and in the
power supply connector.
3. Check whether wire numbers 1 & 2, the sensor, are fastened properly in the plug and in the power
supply connector.
4. Check whether wire numbers 3 & 4, the heating element, are fastened properly in the plug and in
the power supply connector.
5. Check whether fuses F1 & F2 for supplying power to the heating element are still intact.
6. Check whether fuses F3 & F4 for supplying power to the electronic elements are still intact.
7. Check whether fuses F5 & F6 for the secondary alternating voltage for the electronics are still
intact.
8. Check for damage to the flat cable which runs from the power supply board to the control board.
9. Check whether the flat cable which runs from the control panel to the control board is damaged or
has come loose.
10. Check the air pressure. This should be adjusted at around 4 bar.
11. Close the control box and/or coding unit carefully.
12. Connect to the mains voltage by reconnecting the mains cord.
13. Check whether the voltage selection switch, SW2, is switched to the correct voltage: 115 or 230
VAC.
14. Switch it to the correct voltage, 115 or 230 VAC, 50-60 Hz, sinusoidal according to electricity
company requirements.
15. Open the control box using a screwdriver. Handle the cover with care because of the cabling.
16. Test the heating element for continuity. To do so, see Appendix C.
17. Test the sensor for continuity. To do so, see Appendix C.
18. Check the wiring to and in the coding unit. Are they damaged or have they come loose?
19. Check whether the signaldevice entry is properly set using SW1. See Appendix C for instructions
on how to adjust this. The entry needs to be set for the type of sensor; NPN, PNP or 24VDC
voltage pulse.
20. Check whether the wiring of your signal device is properly connected (24VDC, signal, ground,
galv). See Appendix C.
21. Check the wiring of the signal device for damage, such as interruption or short-circuit.
22. Check whether the encoder cable is properly connected to the control box.
23. Check whether wire numbers 5 & 6, the magnetic valve, are fastened properly in the plug and in
the power supply connector.
