For industrial crane operators seeking to enhance measurement accuracy and system reliability, integrating the Siemens 6ES7134-4GB11-0AB0 analog input module into Huisman crane controls offers a proven solution. This guide provides step-by-step instructions for wiring and configuring this 2-channel, 4-wire module, which has demonstrated exceptional performance in Nigerian port operations, improving productivity and data precision.  

Pre-Installation Requirements  

1. Safety Compliance: De-energize all power sources before installation. Only qualified personnel trained in Siemens SIMATIC systems and crane safety standards (e.g., ISO 9928-1 ) should perform these tasks.  

2. Components: Ensure availability of the 6ES7134-4GB11-oABo module, a compatible ET 200SP baseplate, shielded cables, and Huisman crane sensors (e.g., pressure transducers or load cells).  

Step-by-Step Wiring and Configuration  

1. Module Mounting and Power Connection  

- Install the module into the ET 200SP rack, ensuring secure seating.  

- Connect the system power supply (24 V DC) to the rack’s power bus. The module draws power via the backplane .  

2. Sensor Wiring for 4-Wire Configuration  

The module supports 4-wire sensors, where two wires supply power, and two transmit signals:  

- Channel 1 (Terminals 1–4):  

  - Connect the sensor’s positive signal wire to terminal 1 (M+).  

  - Link the negative signal wire to terminal 2 (M-).  

  - Supply external power to the sensor:  

    - Terminal 3 (L+) provides 24 V DC to the sensor’s positive supply.  

    - Terminal 4 (Mana) serves as the analog reference ground .  

- Channel 2 (Terminals 5–8): Repeat the same pattern for the second sensor.  

- Shielding: Ground cable shields at one end to prevent noise interference, critical in crane environments with heavy machinery.  

3. Configuration via Siemens TIA Portal  

- Set the module parameters:  

  - Select 4-wire current measurement (e.g., 4–20 mA).  

  - Enable diagnostics for fault detection (e.g., wire break monitoring).  

- Assign I/O addresses aligned with the Huisman PLC program.  

4. Testing and Commissioning  

- Verify sensor readings against the PLC input values.  

- Calibrate zero and full-scale settings to match Huisman crane operational ranges (e.g., load weight limits).  

Benefits for Huisman Crane Applications  

- High Accuracy: 4-wire design eliminates lead resistance errors, vital for precise load monitoring.  

- Reliability: Robust performance in harsh environments, as evidenced by Nigerian clients reporting reduced downtime.  

- Integration: Seamless compatibility with PROFINET networks in Siemens-based control systems.  

Critical Safety Note  

Always engage certified automation engineers for installation. Adhere to Huisman crane manuals and Siemens documentation  to ensure compliance with safety standards like GB/T 17909.1 . Test all functions before operational deployment.  

The 6ES7134-4GB11-0A80 module, with its straightforward wiring and diagnostics, is a trusted choice for optimizing Huisman crane efficiency. Nigerian users have confirmed 15% productivity gains through stable analog signal processing. For tailored support, consult Siemens technical resources or local distributors.
