5. Installation & Replacement Procedure

5.1 Pre‑requisites

• Qualified personnel only: Requires Yaskawa‑certified technicians

• ESD protection: Anti‑static wristband and mat mandatory

• Power OFF: Disconnect controller main power; wait 5 minutes for capacitor discharge

5.2 Step‑by‑Step Replacement

1. Locate the CPU slot: Identify Slot 0 on the XBB01/XBB02 backplane.

2. Disconnect cables: Unplug CN1（power）, CN3（Ethernet）, CN4（RS‑232C）.

3. Remove old board: Loosen upper/lower screws; spread board levers; pull forward to extract.

4. Install new board: Align with Slot 0; insert firmly until seated; tighten screws.

5. Reconnect cables: Restore CN1, CN3, CN4 connections.

6. Power ON & verify:

   • PWR LED ON

   • RUN LED blinking

   • ALM LED OFF

   • COM LED blinks on network activity

5.3 Post‑Installation

• Battery check: Replace lithium battery if >3 years old.

• Program restore: If SRAM data lost, restore from CompactFlash backup.

• System initialization: Re‑load CMOS file and user programs if required.

6. Troubleshooting

6.1 ALM ON / RUN Not Blinking

• Check 24 VDC at CN1; verify backplane power supply.

• Re‑seat CPU board in Slot 0; clean gold‑plated contacts.

• Replace lithium battery; check SRAM integrity.

6.2 Ethernet Communication Failure

• Verify Ethernet cable and RJ45 connection.

• Check IP address settings; ping controller from host.

• Re‑seat XIF03‑1 daughter card; inspect for damage.

6.3 User Program Loss

• Replace lithium battery（every 2–3 years）.

• Restore programs from CompactFlash backup.

• Check for loose battery holder or damaged wiring.
