• Weight: approx. 0.44 kg

• Mounting: standard Quantum rack slot

4. LED Indicators

• PWR (Green): ON = module powered and 5 V rail OK; OFF = no power or supply fault

• RUN (Green): ON = active, communicating with main rack; FLASH = initialization or link fault

• FAULT (Red): ON = overvoltage, undervoltage, or short circuit in extension rack; OFF = normal

• LINK (Yellow): ON = backplane link established; FLASH = data activity

5. Installation & Wiring

Rack Installation

1. Insert the 140XBE10000 into an empty slot in the main Quantum rack (typically slot 0 or last slot).

2. Push firmly until the module latches into place.

3. For multi‑rack systems, connect the extension rack backplane cable to the expander’s dedicated port.

4. Secure all cables and ensure proper grounding.

Power Wiring

• External 24 V DC: connect to module’s V+ and 0 V terminals

• Ground: connect module chassis to system earth ground

• Cable: use twisted pair, 18–24 AWG, max length 500 m

System Grounding

• Separate signal ground from power ground

• Single‑point earth ground for all racks

• Shield cables at one end only

6. Configuration (Unity Pro)

1. Open Unity Pro V7.0 or later.

2. In the hardware configuration, add 140XBE10000 to the main rack.

3. Define the number of extension racks and slots per rack.

4. Enable backplane diagnostics and fault reporting.

5. Map I/O modules in extension racks to the CPU I/O image.

6. Download the configuration to the CPU; the expander initializes automatically.

7. Operation & Diagnostics

Normal Operation

• PWR: ON

• RUN: ON

• FAULT: OFF

• LINK: ON (steady or flashing)

Fault Conditions

• FAULT ON: Check extension rack wiring, short circuits, or I/O module failures. The expander shuts down power to the extension rack to protect the main system.

• RUN Flashing: Verify backplane cable connection, seating of the expander, or CPU configuration.

• PWR OFF: Check external 24 V DC supply and wiring.

Diagnostic Data

• The expander provides status words to the CPU, including:

  • Voltage rail status (+5 V, ±12 V)

  • Backplane link quality

  • Overcurrent/short‑circuit flags

  • Module temperature

8. Maintenance

• Monthly: Inspect LED status and cable connections

• Quarterly: Verify torque on terminal blocks; clean module vents

• Semi‑annually: Test fault isolation by simulating a short in an extension rack

• Firmware: Update via Unity Pro as recommended by Schneider Electric

9. Safety & Compliance

• Qualified personnel only for installation, wiring, and maintenance.

• Disconnect all power before servicing the module or rack.

• This module is for industrial control systems only; not for direct life‑safety applications without additional safety layers.

• Follow all local electrical codes and safety regulations.

10. Compatibility

• Quantum CPUs: 140CPU65150, 140CPU67160, 140CPU68060, 140CPU69060 and later

• Software: Unity Pro V7.0+, Concept V2.6+

• I/O modules: all standard Quantum digital/analog I/O, safety, and specialty modules
