Menu Item Description
Set Point
Enters the engineering unit value where the alarm trips. It may be negative and trip
when monitored values fall out of range in this direction. A3 has a default negative
5% of range Set Point with Low Trip set for YES. This makes it function as a
FAULT alarm and trip when the monitored value is more than 5% “out of range”.
Dead-Band
Has a minimum value of 1% and a maximum value of 10%. It is useful for
preventing alarm cycling of 0-100 ppm, if Dead-Band equals 5% and the set point is
20 ppm, after tripping at 20 ppm the value must drop below 15 ppm to reset.
ON Delay
Allows entering a maximum 10 second delay before this alarm becomes active.
This is useful for preventing nuisance alarms caused by brief spikes beyond the set
point.
OFF Delay
Allows entering a maximum 120 minute delay before clearing an alarm after the
alarm condition is gone. This is useful for continuing an alarm function, such as
operation of an exhaust fan, for a period of time after the alarm condition clears.
Low Trip
(Default set to YES) Causes the alarm to trip as the value falls below the set point.
Latching
(Default set to YES) Causes the alarm to remain active even after the condition is
gone and only reset when the UP/RESET key is pressed from a data display.
