Chapter 4 Operator Control And Display Panel

This chapter expounds the functions and use of the components on the operator control and display panel of the HIPULSE U UPS, and provides LCD display information, including the LCD screen types, detailed menu messages, prompt windows and UPS alarm message list

4.1 Introduction

The operator control and display panel is located on the front door of the UPS. The panel is the access point for operator control and monitoring of all measured parameters, UPS and battery status and of event and alarm logs.

The operator control and display panel is divided into three functional areas: mimic power flow chart, graphic LCD monitor with menu keys, control buttons, as shown in Figure 4-1.
