1. Introduction
The Knowtek DSE5220 Auto AMF Generator Controller is designed to automatically start and stop diesel and gas generating sets that include non-electronic engines. This module provides comprehensive engine monitoring and protection features, ensuring reliable operation of your generator.
The DSE5220 controller monitors various critical conditions, including:
- Under speed and over speed
- Charge failure
- Emergency stop activation
- Low oil pressure
- High engine temperature
- Failure to start or stop
- Under/over generator volts and frequency
- Over current conditions
- Low/high DC battery volts
- Low fuel alarm
- Loss of speed sensing signal
Fault conditions are clearly displayed on the integrated LCD screen and via LED indicators on the front panel, allowing for quick identification and response.
The DSE5220 also features RS232 or RS485 communication capabilities, enabling connection to a PC, sending SMS messages, and integration with new and existing building management systems. This controller is suitable for gas and diesel generators greater than 10 KW that are started with a battery.
