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.
When an alarm occurs, the LED for ALARM switches on and the alarm message flashes on the
display. For more information, read Acknowledging alarms on page 62.
