Key Features and Capabilities
- Automatic Start/Stop Control: Initiates generator startup upon loss of mains (standby mode) or according to a programmable schedule (prime power mode). Automatically transfers load and performs cooldown shutdown.
- Mains and Generator Protection: Monitors voltage, frequency, and phase sequence for both utility supply and generator output. Provides configurable over/under voltage, over/under frequency, phase reversal, and loss of mains detection.
- Synchronization & Load Sharing: Supports automatic synchronization to the utility grid or to other generators in parallel operation. Enables active and reactive load sharing in multi-unit installations.
- Advanced Monitoring: Continuously tracks critical parameters including engine speed (RPM), oil pressure, coolant temperature, battery voltage, kW, kVA, kVAR, PF, current, and cumulative run hours.
- Digital I/O Flexibility: Equipped with multiple programmable digital inputs and relay outputs for interfacing with sensors, breakers, alarms, and auxiliary equipment.
- Communication Interfaces: Features integrated Ethernet (Modbus TCP), RS-485 (Modbus RTU), and CAN bus (J1939) for seamless integration into SCADA systems, Building Management Systems (BMS), and remote monitoring platforms.
- User Interface: High-resolution color touchscreen display with intuitive menu navigation, real-time trending, event logs, alarm history, and diagnostic tools.
- Configurable Logic: Supports user-defined logic functions, timers, and interlocks via built-in software tools for custom application requirements.
- Cyber Security: Includes modern security features such as password protection, role-based access control, and secure communication protocols (depending on firmware version).
- Compliance & Certification: Designed to meet international standards including ISO 8528, IEC 60255, UL 2200, and CSA C22.2 No. 107.1.
