7320MKII Auto Start Controller – Advanced AMF Control for Modern Generator Systems

1. Advanced Automatic Mains Failure (AMF) Logic
The 7320MKII Auto Start Controller is a professional-grade control unit designed for seamless generator automation, featuring industry-leading AMF functionality. It continuously monitors grid voltage, frequency, and phase balance, automatically starting the generator within seconds of a mains failure and transferring critical loads without interruption. When grid power is restored, the controller executes a smooth retransfer to mains power and initiates a controlled generator shutdown after a programmable cool-down period, eliminating the need for manual intervention. This makes it ideal for data centers, hospitals, and industrial facilities where downtime is not an option.

2. Comprehensive Multi-Parameter Monitoring & Protection
At its core, the 7320MKII provides robust protection for both engine and electrical systems, with real-time monitoring of:
Engine Parameters: Oil pressure, coolant temperature, RPM (via magnetic pickup, 70V/10kHz max), fuel level, and starter health.
Electrical Parameters: Generator voltage (up to 600Vac, 50/60Hz, 1-3 phase), current, frequency, and battery voltage (DC supply 8-35V).
System Faults: Over/under voltage, overcurrent, short-circuit, overspeed, and low oil pressure, with graded protection actions (alarms for minor faults, emergency shutdown for critical issues).
All fault events are logged with time stamps, enabling technicians to quickly diagnose and resolve issues, reducing maintenance downtime.

3. Intuitive User Interface & Flexible Programming
The 7320MKII features a clear backlit LCD display paired with a dedicated keypad (navigation keys + function buttons) for intuitive operation:
Status Display: Real-time readings of generator performance, mains status, and fault codes.
Function Buttons: Quick access to manual start/stop, auto mode, alarm reset, and system tests.
USB Programming: A front-panel USB port allows for easy configuration of over 100 parameters (start/stop delays, load transfer thresholds, protection setpoints) via dedicated software, with support for saving/loading configuration files for batch deployment.
This user-friendly interface reduces training time and minimizes operational errors, even in high-stress environments.


4. Robust Industrial Design & Connectivity
Built to withstand harsh industrial and marine environments, the 7320MKII features:
Heavy-Duty Enclosure: A rugged black plastic casing with IP54 front protection, resistant to dust, moisture, and vibration (operating temperature: -20°C to +70°C).
Secure Terminal Blocks: Rear-mounted green terminal blocks (labeled 1-55) provide stable, vibration-resistant connections for sensors, actuators, batteries, and auxiliary outputs, simplifying installation.
Expandable Connectivity: RS485/RS232 communication ports enable integration with SCADA, BMS, and remote monitoring platforms, while support for ECU and SCR interfaces ensures compatibility with modern engine technologies.

5. CE & ISO 9001 Certified Quality Assurance
Every 7320MKII controller is manufactured in an ISO 9001 certified facility and meets CE EMC and LVD directives, ensuring compliance with global electrical safety standards. Rigorous pre-shipment testing includes functional validation, environmental simulation, and vibration testing, guaranteeing consistent, failure-free performance in critical applications.

1. Critical Facility Backup Power
The 7320MKII is the backbone of backup power systems for data centers, hospitals, and industrial plants, ensuring zero downtime during grid outages and protecting sensitive equipment and life-saving services.

2. Commercial & Industrial Standby Generators
Widely used in commercial buildings, manufacturing facilities, and retail stores, the controller provides reliable backup power with automatic operation, even when facilities are unoccupied.



3. Remote & Off-Grid Power Systems
Ideal for telecommunications towers, remote mining sites, and agricultural installations, the 7320MKII operates reliably in harsh environments with minimal maintenance, while remote monitoring capabilities reduce operational costs.

4. Generator Parallel Cabinet Systems
In parallel systems, the controller coordinates multiple generators to share loads evenly and start/stop based on demand, ensuring efficient and redundant power delivery for large-scale industrial applications.

5. Retrofit of Legacy Controllers
The 7320MKII is a direct drop-in replacement for outdated manual controllers, upgrading existing generator systems with advanced automation and protection without costly overhauls.

6. OEM Integration for Generator Manufacturers
Leading generator OEMs integrate the 7320MKII into their products to meet global safety and performance standards, enhancing product competitiveness in international markets.

The 7320MKII Auto Start Controller sets a new standard for generator control, combining advanced AMF functionality, comprehensive protection, flexible programming, and robust industrial design. Whether used in critical backup power systems, remote off-grid applications, or modern parallel generator setups, it delivers reliable, uninterrupted power when it matters most. Backed by global certifications and rigorous quality control, it is a trusted choice for operators and manufacturers worldwide.
