AMF EMS927V4 GREAVES GENSET CONTROLLER

AMF EMS927V4 GREAVES GENSET CONTROLLER

The Greaves AMF EMS927V4 is a state-of-the-art Automatic Mains Failure (AMF) controller designed for superior management and protection of diesel generator sets. Engineered for reliability and ease of use, this microprocessor-based controller ensures your backup power system operates seamlessly during mains power outages, safeguarding your critical operations in industrial, commercial, and infrastructure applications.

This robust controller provides comprehensive monitoring, automatic start/stop functionality, and critical alarm protection, making it the intelligent heart of your Greaves genset.

Key Features & Benefits

1. Automatic Mains Failure (AMF) Functionality

• Benefit: Ensures uninterrupted power supply. The controller automatically detects a mains (utility) power failure, starts the generator, and transfers the load without any manual intervention. When mains power is restored, it automatically retransfers the load and shuts down the genset.

2. Intuitive LCD Display

• Benefit: Clear and comprehensive visibility of all vital generator parameters at a glance. The backlit display shows essential data like voltage, current, frequency, engine speed, oil pressure, coolant temperature, and operating hours.

3. Comprehensive Monitoring & Alarms

• Benefit: Proactive system protection. The EMS927V4 continuously monitors the generator set for critical faults, including:

  • Low Oil Pressure

  • High Coolant Temperature

  • Over-speeding / Under-speeding

  • Over Crank

  • Fail to Start

  • Overload

  • Battery Low Voltage
    Immediate alerts and automatic shutdown prevent costly damage to your engine and alternator.

4. User-Friendly Control Interface

• Benefit: Simple operation for all users. The keypad and display allow for easy start/stop commands (Auto/Manual/Test modes), parameter configuration, and viewing of historical fault logs for simplified troubleshooting.

5. Robust Construction & Design

• Benefit: Built to last in demanding environments. The controller is housed in a durable enclosure, designed to withstand the vibrations, temperature variations, and humidity typically found in generator operating conditions.

6. Precise Engine Parameter Management

• Benefit: Optimizes engine performance and life. The controller manages pre-heat timer, cool-down timer, and number of crank attempts, ensuring your generator starts reliably and shuts down properly every time.
