Interlock error
Detection Description
No detection of Interlock (24 V) although all the Doors (Front Cover and Right Cover) of the host
machine were closed.
Remedy
[Related parts] R1.00
- Harness between the DC Controller PCB (UN04/J24) and the Interlock Switch 2 (SW03)
- Harness between the DC Controller PCB (UN04/J20) and the Low-voltage Power Supply PCB
(UN01/J315)
- Front Cover/Right Cover
- Low-voltage Power Supply PCB (UN01)
- DC Controller PCB (UN04)
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Check that the Front Cover/Right Cover is closed.
2. Visually check that the Interlock Switch 2 are turned ON/OFF by opening/closing the Front
Cover/Right Cover.
3. Check that the harness between the Interlock Switch 2 and the DC Controller PCB is not short-
circuited (the harness does not come in contact with the plate while the cable sheath is peeled).
4. Disconnect the connector (J24) of the DC Controller while the Front Cover and the Right Cover
are closed, and measure the resistance value between the connectors J24/1-pin and the J24/3-
pin on the J24 harness side using a tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the DC Controller PCB.
2. Replace the Low-voltage Power Supply PCB.
b. If the measurement value is 1 ohm or higher (non conduction state), replace the harness
between the Interlock Switch 2 and the DC Controller PCB.
5. Check the harness between the Low-voltage Power Supply PCB and the DC Controller PCB.
6. Replace the DC Controller PCB.
7. Replace the Low-voltage Power Supply PCB.
[Reference] Before replacing the DC Controller PCB, back up the service mode data (approx. 2
min) and restore the backup data after the replacement so the data may be able to be protected.
