8.7 Adjusting & Resetting Dryer Set Points
Dryer Set Points are simply limits programmed for a specific reading. Once this limit
is reached (or exceeded) this results in an alarm for that reading. Each of these set
points is factory programmed with a default value based on typical usage of the air
Dryer. Many of the set points for Dryer alarms can be modified to levels more
closely based upon your specific application.
