Model DSE7420MKII Controller A dedicated electric control module for diesel generator sets that detects mains failure and performs automatic selfstart and stop. Designed to improve transfer performance and overall reliability of generatorbased standby systems. Key benefits Automatic mainsfailure detection and selfstart: Quickly starts the generator when utility power fails and returns to standby when mains is restored, minimizing downtime. Simplifies installation and operation: Centralizes control functions for generator set starting, stopping, and status monitoring to reduce wiring complexity and setup time. Improves transfer performance: Electric control logic optimizes the handover between mains and generator supply to support stable power delivery. Reliable system control: Provides consistent, repeatable responses for emergency and standby applications, helping maintain continuity of critical loads. Primary functions and attributes Function: Mainsfailure detection, automatic selfstart and stop control for diesel generator sets, basic monitoring and engine control interface. Compatibility: Intended for use with diesel generator sets and standard engine and alternator control signals. Suitable for integration with existing transfer switches and control wiring. Form factor and mounting: Compact controller module designed for installation in generator control panels or enclosures where space for a dedicated control module is required. Construction and durability: Electronic control module built with standard industrial components for dependable operation in engine room and plant environments. Performance: Fast detection and response to mains loss, stable control of start/stop sequences, and repeatable performance under routine standby conditions. Practical applications Commercial building standby power: Automatically starts backup generators when utility power fails to protect lighting, HVAC, and critical systems. Remote or temporary sites: Controls portable or fixed diesel gensets on construction sites, outdoor events, and temporary installations where unattended automatic start is needed. Industrial and manufacturing plants: Provides dependable automatic starting and control for standby generators that support production lines or essential process equipment during power interruptions. What to expect A control module that focuses on mainsfailure selfstart functions for diesel generator sets. Straightforward compatibility with standard generator control arrangements and transfer switch systems. A practical solution for improving reliability and reducing manual intervention in standby power applications. Model reference: DSE7420MKII
