Gap voltage validation logic continuously samples the DC bias level against a nominal -10 VDC reference, ensuring correct probe standoff before enabling trip signaling. This prevents false machinery shutdown due to probe contact loss or target surface anomalies.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the module support hot-swap replacement in the 7200 rack?\u003c\/p\u003e\n\u003cp\u003eA: No. The 7200 system backplane does not support live insertion; power must be removed before removing or installing the 18745-02 to avoid transient faults.\u003c\/p\u003e\n\u003cp\u003eQ: Can both channels operate with different probe types?\u003c\/p\u003e\n\u003cp\u003eA: Both channels must use compatible eddy-current transducer types within the same module. Mixing 5 mm and 8 mm probes requires separate configuration verification for each channel's scale factor.\u003c\/p\u003e\n\u003cp\u003eQ: What is the relay switching delay in danger condition?\u003c\/p\u003e\n\u003cp\u003eA: Relay activation occurs within milliseconds after exceeding the configured danger setpoint, subject to any user-set time delay jumper configuration.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 18745-02 into the designated 7200 rack slot, ensuring correct alignment with guide rails and backplane connectors. Apply even pressure during insertion to avoid connector pin damage. Use shielded twisted-pair cable for probe signal wiring, grounding the shield at the rack end only to minimize ground loops. Verify gap voltage at each probe prior to enabling monitoring functions. Perform functional testing by simulating probe displacement and confirming proportional output change and alarm relay operation.\u003c\/p\u003e","brand":"Bently Nevada","offers":[{"title":"Default Title","offer_id":44319619678296,"sku":"18745-02","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0670\/2039\/0488\/files\/18745-02-3.jpg?v=1783067911","url":"https:\/\/www.industriaxplc.com\/products\/bently-nevada-18745-02-7200-series-monitor-module","provider":"IndustriaX Limited","version":"1.0","type":"link"}
