Acronym Scrolling message Submenu Attributes
HYSTE HYSTERESIS ALARM R W
IThe parameter shows and sets the hysteresis applied to the alarm setpoint value for the alarm being configured.
Unit of measurement: Scale points
Options: 0...999 = For absolute (A.r.x = ABSLT) and symmetrical alarm (n.S.x = SYMMT)
-999...999 = For other types of alarms
4.11.9. DELAY - Alarm trip delay
Acronym Scrolling message Submenu Attributes
DELAY DELAY OF ACTIVATION ALARM R W
The parameter shows and sets the alarm trip delay for the alarm being configured, i.e., the time that the value of the process
variable has to exceed the alarm setpoint for the alarm to trip.
This parameter prevents repeated alarms due to instantaneous and insignificant exceeding of that value.
If the parameter is set to “0.00” the alarm will be instantaneous, regardless of the time in which the process variable exce-
eds the alarm setpoint.
For a detailed explanation of this behavior, see paragraph “5.6.1. Generic alarms AL1...AL4” on page 142.
Unit of measurement: Minutes.seconds
Options: 0.00...99.59

If the parameter is set to “0” no message will be displayed when the alarm trips.
The same message number can be assigned to different alarms
Unit of measurement: Message number
Options: 0...25
