The Display Master4 is a microprocessor-based engine/generator controller for monitoring and control of diesel or gas powered engine-generator sets. It provides a complete array of operational, protection, automation and display features for automatically controlling and monitoring an engine/generator set. All standard and optional features of the Display Master4 are configurable from the front panel keypad and LCD display and are security password protected. The 2 row 16 character LCD display screen prompts are in plain English, providing a user-friendly operator interface. The solid-state microprocessor design provides high accuracy for all voltage monitoring, current monitoring and timing functions as well as providing many standard features which are normally only available with expensive add-on equipment.
