6.2Setup System - Overview

The Setup System screen displays six options that allow you to configure zones with cable, alarm outputs, the re-alarm delay time, log points to create a map and system details, such as changing the login password or the system date and time:

Setup ZN1 Zone 1

Setup ZN2 Zone 2

Setup Alarm Outputs

Setup Re-Alarm Delay

Setup Mapmode

6.3Setup System - Setup ZN1 Zone 1

The Liqui-tect panel has two independent zones—ZN1 and ZN2—that may be configured individually. Each zone can monitor up to 5,000 ft. (1524m) of cable.

If neither zone is configured as connected, the screen displays the message:

WARNING! NO ZONES ARE INSTALLED

To configure the first zone:

Log In and Choose Setup System

• From the Main Menu, use the arrows ↑↓ to choose System and Control, then press Enter (see 6.1 - Login for help).

• Enter your password at the Login screen.

• From the System and Control Menu, use the arrows ↑↓ to choose Setup System, then press Enter .

• From the Setup System Menu, shown at right, use the arrows ↑↓ to choose Setup ZN1 Zone 1 and press Enter .

• Use the steps following Table 8 to change the default settings for Zone 1.

Table 8 shows the features you may change for Zone 1, along with the default settings. By default, Zone 1 is not connected.

To activate Zone 1, you must specify it as connected. Other features that may be altered include the name of the zone, the measurement units, and the sensitivity for detection of water and of contamina- tion. You may also initiate automatic calibration, during which the Liqui-tect panel determines the length of cable and parameters.
