Alarm settings worksheet
The alarm settings for your PEC Plus determine which alarm conditions are enabled, which are
disabled, and their settings. All these work together to determine how and when the alarm relay
activates (in other words, signals an alarm condition).
The alarm relay activates if an alarm condition (one that is enabled) is present for longer than the
minimum duration of one minute. The one minute minimum duration prevents alarms from
occurring when the temperature rises or drops for just a few seconds.
For more information, read Programming alarm settings on page 58.
