4.11.8. HYSTE - Hysteresis

Acronym
HYSTE HYSTERESIS
IThe parameter shows and sets the hysteresis applied to the alarm setpoint value for the alarm being configured.
Unit of measurement:
Options:

4.11.9. DELAY - Alarm trip delay

Acronym
DELAY DELAY OF ACTIVATION
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.

4.11.10. MSG.AL - Message associated with tripping of alarm

Acronym
MSG.AL SCROLLING MESSAGE AT ALARM ACT
The parameter shows and sets the number of the message associated with tripping of the alarm being configured, i.e.,
the scrolling message shown on the display.
For more information on scrolling messages, see paragraph "3.1.2.2. Scrolling messages" on page 34.
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

4.11.11. BLK.AL - Flashing of PV display

Acronym
