4. Product Introduction
The ABB AX460/100010/STD is a single input analyzer for pH or Redox (ORP) measurement. It accepts one electrode input with temperature compensation and provides local display, retransmission, and control functions.
Water treatment and process engineers use it for reliable pH monitoring and dosing control in applications such as wastewater, power, chemical, and pharmaceutical plants. The wall-mount enclosure simplifies field installation.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No display/power | Supply voltage issue | ❌ Low | Measure at power terminals | Verify 100-240 VAC input |
| Unstable or drifting reading | Electrode fouling or calibration | ✅ High | Check electrode response in buffer | Clean or recalibrate electrode |
| No 4-20 mA output | Configuration or wiring | ✅ Medium | Measure output current with multimeter | Confirm loop wiring and scaling |
| Relay not activating | Setpoint or logic error | ✅ High | Review alarm/relay parameters | Adjust setpoints in menu |
| Temperature error | Sensor fault | ✅ Medium | Measure RTD resistance | Check or replace temperature sensor |

6. Frequently Asked Questions (FAQ)
Is this a single or dual input unit? This configuration (100010) is single input pH/ORP with PID control option. Dual input variants exist in the AX46x series.
What condition are these analyzers? New Original / New Surplus. Units are tested for display, output, and basic calibration functionality prior to shipment.
What electrodes are compatible? Standard glass pH, enamel, or metal Redox (ORP) electrodes with appropriate temperature compensators. ABB recommends matching reference systems.
How do I calibrate? Use standard pH buffers (4, 7, 10). Follow the on-screen prompts for 1- or 2-point calibration. Temperature compensation should be active.
Does it include PID control? Yes, this model supports integral P, PI, or PID control for dosing or neutralization applications.
What power and mounting options? 100-240 VAC supply. Wall/pipe mount IP65 enclosure with cable glands. Panel mount variants available in the series.
