4. Compatibility & Installation

4.1 Compatibility

• Exclusively compatible with Motoman XRC series robot controllers.

• Not compatible with NX100, NXC100, DX100/DX200, or Yasnac CNC systems.

4.2 Installation Steps

1. Power off the XRC controller and wait ≥5 minutes for capacitor discharge (prevents electric shock).

2. Wear an ESD wristband connected to a grounded metal surface (avoids static damage).

3. Insert JANCD-SP17B into the designated backplane slot; ensure edge connectors are fully seated.

4. Secure the board with mounting screws.

5. Connect the LCD cable to the 20-pin LCD port; connect the keypad/LED harness to the 12-pin header.

6. Power on the controller and verify: LCD initializes, LEDs light correctly, and buttons respond.

5. Maintenance & Safety

5.1 Routine Maintenance (Every 3 Months)

• Inspect cables/connectors for looseness, dust, or oxidation.

• Clean the board surface with a dry, lint-free cloth only (no liquids/solvents).

• Check for physical damage (cracks, burnt components).

5.2 Critical Safety Rules

• ESD Protection: Always ground yourself when handling the board (static damages ICs).

• Power Safety: Disconnect all power before removal/inspection/maintenance.

• Qualified Personnel: Installation/service must be done by trained technicians familiar with XRC systems.

6. Troubleshooting

6.1 LCD No Display

• Causes: Loose LCD cable, poor backplane connection, faulty LCD module.

• Fix: Power off, reseat cables/board; test LCD module if issue persists.

6.2 Buttons/Panel Unresponsive

• Causes: Disconnected/damaged keypad harness, faulty switches, board trace damage.

• Fix: Power off, verify harness continuity; inspect switches and board traces.

6.3 All LEDs Off

• Causes: Abnormal 5 VDC supply, faulty board power circuit.

• Fix: Check backplane power output; inspect board power connector/circuitry.

6.4 Board Not Recognized by CPU

• Causes: Improper insertion, dirty/oxidized edge connectors, bus fault.

• Fix: Power off, remove/reinstall board; clean edge connectors with dry cloth.
