3.14 Alarms Set Up Group
Introduction
This data deals with the Alarms function that is available with your recorder.

There are six alarms available. Each alarm has two setpoints.

You can configure each of these two setpoints to alarm on various recorder parameters. There are two
alarm output selections, high or low.

You can also configure the two setpoints to alarm on the same event and to alarm both high and low, if
desired. An adjustable hysteresis of 0.0% to 100.0% is configurable for each alarm.
Priority of functions that operate relays
During alarm conditions an alarm will deenergize its associated relay unless a higher priority function has
been configured for that relay. See Table 3-11. If you want the alarm to control the relay, do not configure
a higher priority function.
