2.2Detailed Component Descriptions

2.2.1Controls Hardware

The Series 610 UPS Operator Interface Display System is designed to provide all of the information that is required for the operation of each UPS cabinet (the System Control Cabinet and each module). The following is a list of the hardware features:

1.The control logic performs automatic operations with minimal operator interface. The limited number of manual controls are easy-to-use.

2.Each Series 610 UPS cabinet is equipped with an easy-to-read 640 x 200 pixel backlit liquid crystal display (LCD) screen. It presents information in a way that is easy to understand at an eye-level front panel location.

3.The display is controlled by a dedicated microprocessor with a flash-updatable program, non- volatile static RAM and a battery-backed system clock.

4.The Series 610 System Control Cabinet (SCC) has communication ports (terminal board connections) for:

a.Transmission of present status information to remote terminals via a resident auto-dial communications program and an optional internal or external modem. This port also responds to inquiries of the UPS system status and history from the remote terminal.

b.Reporting UPS system status and history information in response to inquiries from a local terminal (no modem required).

c.Reporting to a local monitor the information requested from the local terminal.

d.Reporting information to a Liebert SiteScan central monitoring system.

e.Relaying selected alarm messages to a Liebert Remote Monitor Panel and to a separate terminal board for customer use.

f.Relaying performance and status information to your network monitoring system via SNMP interface (optional).

Software

The operator interface display system software enables the operator to monitor the UPS system sta- tus, to control the power flow through the UPS, to monitor all of the meter readings, to execute the start-up, shutdown and load transfer procedures, to access the event history files and to make adjust- ments to the programmable parameters. The following is a list of the software features:

1.The menu-driven software prompts the operator for input.

2.Step-by-step instructions assist the operator during the start-up, shutdown and load transfer procedures. This helps to eliminate operator errors.

3.Graphics-based mimic diagrams illustrate circuit breaker status and the power flow through the UPS system.

4.The Present Status screen reports information about the system’s present status. The History Status screen chronicles the events leading up to and immediately after a fault. The Event History screen lists all of the alarm messages that have been logged over a period of time.

5.The Battery Cycle Monitor records information on up to 132 battery discharge events. Information includes date, time, length of discharge, highest current demand, lowest battery voltage and cumulative battery amp hours discharged.

Refer to 3.0 - Operation for a description of the controls and indicators located on the Operator Con- trol Panel.
