Chapter 5 Operator Control And Display Panel
This chapter expands the functions and use of the components on the operator control and display panel of the UPS,
provides LCD display information, including the LCD screen types, detailed menu messages, prompt windows and
UPS alarm list, and tells how to select language and change the current data and time.
5.1 Introduction
The operator control and display panel is located on the front door of the UPS. It is the access point for operator
control and monitoring of all measured parameters, UPS and battery status and alarms. The operator control and
display panel is divided into three functional areas: mimic power flow chart, LCD display with menu keys, control keys,
as shown in Figure 5-1. The components on the operator control and display panel are described in Table 5-1.
