Output Alarm: An output (pump) is programmed to set an alarm if it stays on for

more than 30 minutes (a 30 minute recognition time). The alarm will not be set

unless the pump has been on for 30 continuous minutes. If the pump shuts off

after 28 minutes, the recognition time will start over from 0 the next time the

pump turns on.

Variable Alarm: A calculation within a C program computes the average volume

of material traveling through a pipe. This variable is referenced as the input

source for an alarm. The calculation must result in a value that exceeds the pro-

grammed alarm limits, for the programmed recognition time, before an alarm

will occur.

When an alarm is detected, three things happen: 1) If any of the dialout destinations are pro-

grammed and enabled, the unit will begin dialing. 2) A record of the alarm will be entered into

the event log. 3) The alarm status will be set to reflect the type of alarm (1 for a general alarm;

2 for a low-level alarm; 3 for a high-level alarm). See Chapter 10 for more detailed information

regarding UAFs.
To program alarm information, click on Programming>Alarms, or click on the Alarms button on

the toolbar. The alarm status form will appear:

Figure 7: Alarm Status

Alarm programming includes three screens: Status, Setup, and Notification. The Status screen

shows the current state of any already programmed alarms. To check on them, use the arrow

buttons in the lower left to move through the list.

Alarm Name

Each alarm can have its own name (up to 24 characters) that can be used to describe the alarm.

Since alarms can be set from any source, it is important to enter a name and be as specific as

possible. If you set an alarm from an input, it is recommended that you use the same name for

both the Input Name and the Alarm Name.

State

This parameter describes the state of the alarm. It tells you whether or not the condition has

met the recognition time, if the alarm exists, if it has been acknowledged or if it has returned to

its normal range. A description of each of the possible messages is listed below:

No Alarm: No alarm exists at the present time. The alarm source is within its pro-

grammed limits.

Waiting: The source of the alarm is presently exceeding its limits but hasn’t met

the recognition time yet.

Alarm, Alarm High, Alarm Low: The source of the alarm has exceeded its alarm

limits for the programmed recognition time. If the source is a Normally Open

or Normally Closed alarm type, the word Alarm will display. If the source is an
