Semi-Auto Controller EEPL-666R Microprocessor Based DG Engine Protection Controller

Semi-Auto Controller EEPL-666R is a microprocessor-based controller made for diesel generator sets. It helps operators monitor the engine and identify common operating faults.

The controller is designed for semi-automatic DG set operation. It provides useful information on the LCD display and helps control important engine functions. The unit can be used with a wide range of generator sets and supports programmable water or air cooling options.

Key Features

• Microprocessor-based DG engine controller
• 2-row, 16-character LCD display
• Engine protection and fault indication
• Oil pressure and water temperature monitoring
• Fuel level monitoring
• Battery voltage monitoring
• Manual and automatic fuel pump control
• Engine idle control for start and stop
• Fault history logging
• 3 resistive-type analog inputs
• 6 digital inputs
• Programmable water or air cooling selection
• Programmable single-phase or three-phase selection

Applications

The EEPL-666R can be used for monitoring and controlling diesel generator sets where semi-automatic operation is required.

Typical applications include:

• Diesel generator panels
• Industrial DG sets
• Commercial power backup systems
• Generator control panels
• Factory backup power systems
• Institutional generator installations
• Engine monitoring systems

Technical Benefits

The controller uses a 32-bit processor with a 21-bit sigma-delta ADC design. This supports accurate measurement and repeatable operation.

Its LCD display makes important readings and fault information easier to check. The controller also supports engine protection functions, fuel control, battery monitoring, and fault history. These features help operators identify problems during generator operation.

The documented controller family supports a wide DC supply range, while the EEPL-666R has a compact panel-mount design. Available documentation lists the EEPL-666R/EEPL-333 mechanical size at 96 × 96 × 65 mm, with a 92 × 92 mm panel cutout.

Industry Usage

The DG engine controller is suitable for industries and facilities that depend on diesel generators for backup power. It can be integrated into generator control panels for monitoring engine conditions and managing basic operating functions.

It is useful where operators need simple display-based monitoring and semi-automatic engine control without a highly complex control system.

Performance Advantages

The Semi-Auto Controller EEPL-666R combines engine monitoring, protection, display, and control functions in one compact unit.

Its key advantages include:

• Easy-to-read LCD information
• Continuous monitoring of important engine parameters
• Fault history for easier troubleshooting
• Battery voltage monitoring
• Fuel pump control
• Engine start-stop control
• Flexible configuration for different DG applications
• Compact panel installation
