Safety functions are exclusively handled by dedicated hardware circuits to ensure instant fault clearing, while a secondary microprocessor subframe tracks internal log registers and handles external human-machine interface (HMI) screen communications.

A firmware flash compatibility mismatch or an HMI disconnection will generate a system warning log but will not block the 1 ms hardware arc fault trip loop.\u003c\/p\u003e\n\u003cp\u003eQ: How does the TVOC-2 module execute zone-selective tripping across multiple circuit breakers?\u003c\/p\u003e\n\u003cp\u003eA: Internal zone routing is configured using physical DIP-switches on the main unit faceplate. When a specific optical channel triggers, the hardware decodes the position map and fires only the designated IGBT output contacts assigned to that fault zone, leaving unaffected breakers closed.\u003c\/p\u003e\n\u003cp\u003eQ: Is hot-swapping of optical sensor extensions permitted while the monitor is powered?\u003c\/p\u003e\n\u003cp\u003eA: No. Connecting or disconnecting expansion units or altering DIP-switch states while the 100-240 V supply rail is active can cause configuration errors or unintentional tripping. De-energize the unit completely before changing the detector configuration profile.\u003c\/p\u003e","brand":"ABB","offers":[{"title":"Default Title","offer_id":46021052694701,"sku":"1SFA664001R1001","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0733\/1613\/9181\/files\/1SFA664001R1001-3.jpg?v=1780481050","url":"https:\/\/www.maxwellplc.com\/products\/1sfa664001r1001-abb-arc-monitor-tvoc-2","provider":"Maxwell PLC Ltd","version":"1.0","type":"link"}
