• It simultaneously tracks bus voltage levels throughout the system
• Potential transformers scale high voltages to measurable levels safely
• Continuous oversight maintains electrical system stability and reliability
• Voltage deviations trigger immediate alerts for preventive actions

Protection Relay Control System

• Three coordinated relays (K25, K25P, K25A) control main breaker operations
• These relays supply 125V DC power to close the main 52G breaker
• Automatic generator synchronization occurs through this relay system
• Jumper settings select between SMX and TMR relay driver configurations
• The system ensures proper sequencing for safe breaker closure

Signal Connectivity & System Integration

• Speed signal cables connect through the JR5 connector interface
• Other critical signals route through the JR1 connector primarily
• TMR systems use six connectors for complete signal redundancy
• Terminal blocks TB1 and TB2 handle all I/O wiring connections
• Shield termination strips provide proper chassis grounding points

Installation & Configuration Guide

• Identify all magnetic pickups and shaft sensors before installation
• Secure terminal blocks TB1 and TB2 using two mounting screws each
• Set jumpers JP1 and JP2 for either SMX or TMR operation modes
• Use TB3 terminal block for optional TTL speed pickup connections
• Simplex systems require JR5 and JR1 connector configurations
• TMR systems need all six cable connectors for full functionality
• Verify all wiring against system specifications before power application
• Conduct comprehensive testing to ensure proper system operation
