It is critical to note that the BK2010 provides a maximum of 0.5 A on the internal K-bus. If your physical I\/O configuration (total energy demand of connected KL terminal modules) exceeds 0.5 A, you must integrate a KB1112 or similar auxiliary power supply terminal, or upgrade to the standard BK2000 to avoid system drops. Parameterization can be verified and modified using the KS2000 serial configuration interface.\u003c\/p\u003e\n\n\u003ch3\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eBecause Lightbus utilizes fiber-optic links (polymer optical fibers), signal attenuation can occur if bend radiuses are too sharp. Always maintain a minimum bending radius of 30 mm for standard fiber optic lines during cabinet installation. Additionally, keep optical connector faceplates clean; airborne dust in industrial spaces can settle on the transmitter and receiver optics, leading to communication errors or complete link degradation.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eEnsure that the 24 V DC system supply is routed through appropriate line filtering if deployed alongside high-frequency AC variable speed drives.
