ALARM STATUS
The ZT indicates an alarm as follows:
•
The warning signal (
s
) flashes to the right of the Display Indicator dot (
l
) if the system operating
values are in alarm.
•
The On/Off Status bar ( | ) or circle (
m
) flashes when an On/Off status is in alarm.
•
The red alarm light to the right of the Mode Selector Panel flashes when any of the above items
are in alarm.
Alarms cannot be cleared with the ZT. The problem must be corrected by maintenance or repair of
the affected item.
MAKING ZONE TERMINAL ADJUSTMENTS
Adjusting Control Settings
1.
You can adjust only a flashing number with the ZT. If the number does not flash, that item is a
monitor only item. Adjust Control Settings in Display 1, 2, or 3 as follows:
2.
Press the Mode Selector Button until the green Mode Indicator Light moves next to the word
Adjust.
3.
Press either Display Button 1, 2, or 3 to locate adjustable items, which are indicated by flashing
numbers.
If you continue pressing the display buttons, the dot (
|
) in each display changes positions and the
corresponding number appears.
4.
Press the Up (
) or Down (
) Arrow key until you reach the number you want to enter. If you
hold down the Up (
) or Down (
) Arrow keys, you can speed through the numbers more
quickly.
Press Enter. After you press Enter, the numbers stop flashing for a few seconds. This pause tells
you the ZT has processed your adjustment.
5.
Press any of the Display Buttons to make other adjustments, and repeat Steps 2 and 3.
