Compact controller with a 4.3 inch color LCD for clear, realtime monitoring in five selectable languages. Designed to simplify automatic transfer switch control and generator management while providing flexible integration and robust fault protection. Key benefits Fast situational awareness: Color LCD shows status and alarms at a glance, reducing response time and helping prevent extended outages. Flexible control options: Builtin automatic start and stop plus ATS switching make it suitable for standby power and mains changeover applications. Remote integration: Native MODBUS support enables easy connection to building management systems and remote supervisory platforms. Reduced downtime and maintenance costs: Blackbox fault logging and a maintenance timer simplify troubleshooting and planned servicing. Adaptable I O and wiring: Seven relays including five programmable outputs and three sensor inputs allow customized configurations for a wide range of installations. Main features 4.3 inch color LCD for realtime monitoring and clear alarm display Five language options, user selectable Auto start and stop control for generator or engine driven equipment Automatic transfer switch switching logic for reliable power changeover Remote control and telemetry via MODBUS protocol Blackbox fault logging to record events for diagnostics Maintenance timer to schedule service intervals Seven relay outputs, five of which are programmable for custom logic Three sensor inputs for temperature, pressure, or other monitored signals Flexible wiring options to fit different panel layouts and installation practices Safetyoriented protection routines to limit incorrect operation and support safe recovery from faults Compatibility and performance Intended for use with ATS systems, generator sets, and control panels that support standard relay and sensor interfaces MODBUS connectivity enables integration with SCADA, building automation, and remote monitoring gateways Display size and layout suit panel mounting or operator console installation where clear local feedback is required Common applications Emergency standby power: Manage automatic transfer between mains and generator, track runtime, and log faults to ensure reliable backup power for critical loads. Remote equipment sites: Use MODBUS to report status and alarms to a central monitoring system, enabling remote start stop and fault diagnosis without site visits. Commercial and industrial control panels: Program relays for sequenced starts, interlocks, or alarm outputs while using sensor inputs to monitor key system conditions. Technical note Display: 4.3 inch color LCD Languages: Five user selectable Control: Auto start stop and ATS switching Remote: MODBUS protocol support Protection: Event logging and maintenance timer I O: Seven relays including five programmable, three sensor inputs This controller is designed for installers and system integrators who need a compact, flexible control interface with clear local feedback, remote integration capability, and reliable fault logging to keep systems operating with minimal disruption.
