Posted by Xwk Tech on
078-301 HCF Docking interlock Open RAP
BSD-ON: BSD 1.11 DC Power Distribution - HCF
078-301 HCF1 side out switch open. The HCF and the IOT were undocked.
Initial Actions
WARNING: Ensure that the electricity to the machine is switched off while performing tasks that do not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause death or injury. Moving parts can cause injury.
• Check that the HCF and the IOT are correctly docked.
• Switch off, then switch on the machine, GP 10.
Procedure
Refer to the procedure that follows as necessary:
• GP 9 How to Check a Switch.
1. Enter dC330 code 078-301. Dock then undock the HCF to actuate the HCF1 side out switch. The display changes. If YES, go to 7. If NO, go to 2.
2. Undock the HCF. Actuate the HCF1 side out switch, PL 70.60 Item 8. The display changes. If YES, go to 6. If NO, go to 3.
3. Measure the voltage between JF08 pin 2 on the HCF PWB and ground. The voltage drops to less than +1VDC when the switch is actuated. If YES, go to 5. If NO, go to 4.
4. Check the wiring between:
• JF08 pin 1 on the HCF PWB and FS003 on the HCF1 side out switch.
• JF08 pin 2 on the HCF PWB and FS004 on the HCF1 side out switch.
If the wiring is good, install a new HCF1 side out switch, PL 70.60 Item 8.
5. Install a new HCF PWB, PL 70.60 Item 9.
6. Check the alignment of the HCF docking base and the IOT.
7. The fault may be intermittent. Check HCF1 side out switch wiring. If the fault persists, install new components as necessary:
• HCF1 side out switch, PL 70.60 Item 8.
• HCF PWB, PL 70.60 Item 9.
