📖 Product User Guide
To install the Hyundai HIMAP-BCS, secure the relay into the designated panel cutout using the included mounting hardware. Connect current transformer (CT) and potential transformer (VT) inputs at the rear terminals, ensuring correct phasing and polarity to maintain accuracy. Configure the protective settings (such as pickup current, time-multiplier, and curve type) using the front-panel interface or the dedicated setup software. After installation, perform a secondary injection test to verify that the relay operates within the expected time parameters. Monitor the “Status” LED to confirm the device is healthy and ready for operation.
❓ Frequently Asked Questions (Q&A)
What does the “BCS” designation stand for? The HIMAP-BCS series is part of Hyundai’s “Basic & Comprehensive” protection relay line, designed to provide a balance of essential protection functions and modern monitoring capabilities for standard distribution systems.
Can this relay be used with SCADA systems? Yes, the HIMAP-BCS features an integrated communication port (RS-485). By configuring the device ID and communication parameters, it can be easily integrated into larger plant automation systems for remote monitoring and centralized control.
What is the best way to extract event records after a fault? Event logs are stored in the internal memory of the relay. You can view the last several fault events, including timestamps and measured values (current/voltage at time of fault), directly on the front-panel display or download them to a PC via the communication interface for detailed analysis.
