System and Control Options

7.0SYSTEM AND CONTROL OPTIONS

NOTE

For ease of understanding, this section uses the LCD interface to illustrate most instructions, except for features that are available only through the Service Terminal Interface. All Service Terminal Interface screens appear in Appendix A - Service Terminal Interface.

The System and Control menu allows you to configure the Liebert AC4—setting up inputs and outputs and system features such as date and time. This menu also provides a vehicle for manually changing the state of an output to ON or OFF, clearing active alarms and deleting records from the Liebert AC4’s alarm and event logs.

The arrows ↑↓ are used to scroll through the menu. The Enter ↵ key is used to select the menu item and enter new information. Table 12 shows characters that may be entered in labels and values.

The System and Control options require a password to prevent unauthorized users from making changes to the system.

This section presents step-by-step instructions for each of the following:

•Login - enter the password

•Setup System - configure inputs, outputs, system features

•Override Output - manually override automatic control of outputs; release the override

•Clear Alarms & Logs - clear active alarms; delete records from the alarm and event logs

NOTE

If an alarm occurs while a user is logged on, the LCD backlight will flash and the audible alarm will sound. To obtain specific information about the alarm, you must access the Active Alarm screen (see 5.1 View Active Alarms) or the Alarm Log (see 5.2 View Alarm Log).
