5.1View Cable Status

The Cable Status screens display the overall status of the cable con- nected to each of the two zones monitored by the Liqui-tect panel, as well as the length of the cable being monitored and the amount of cur- rent present in each cable.

To view the status of the cable:

• From the Main Menu, use the arrows ↑↓ to choose View Status, as shown at right, and then press Enter .

• From the View Status Menu, use the arrows ↑↓ to choose View Cable Status and press Enter .

5.1.1Cable Status Screens

Each Cable Status screen displays the zone name (ZN1 or ZN2) and its label (for example, ZONE 1 or ZONE 2) at the top.

Viewing Additional Screens

There are four Cable Status screens—two for each zone.

To view additional screens, use the arrows ↑↓ .

To return to the previous screen, press the ESC key.

When finished viewing the last screen, press Enter .

Overall Condition

The first screen for each zone shows:

the zone name (ZN1 or ZN2) and its label (for example, ZONE 1 or

ZONE 2)

the current overall condition of the cable (for example, NORMAL)

The cable conditions tracked by the Liqui-tect panel appear in Table 5.
