Open the physical hardware topology configuration tree inside B\u0026amp;R Automation Studio, select the specific slot containing the X20AO4632 module, and navigate to its channel parameter tab.

If a current loop channel detects an open circuit (broken wire or disconnected actuator terminal), a fault indicator will activate. Verify line continuity using a digital multimeter, check the external loop resistance to ensure it falls within permissible limits, and verify that the auxiliary 24 VDC potential feed module is active.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this module output negative voltage signals for bidirectional servo drive control?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The X20AO4632 is calibrated specifically for unipolar industrial signaling standards, providing 0 to 10 VDC or 4 to 20 mA. For application loops requiring bipolar voltage ranges (such as -10 V to +10 V) for hydraulic valves or bidirectional servo controllers, utilize a dedicated B\u0026amp;R bipolar analog output module.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch3\u003eField Commissioning and Wiring Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eShield Termination and Noise Suppression:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eAlways utilize high-quality shielded twisted-pair cables for all analog signal runs.
