limits. For a value to register as having returned to the permissible limits, the
monitored value must rise above or fall below this value for the hysteresis.
The format for entering the hysteresis depends on the monitored analog input
and corresponds with the one of the threshold listed in param‐
eter
2 00.02 to 327.00 If the monitored value exceeds or falls below the threshold value for the delay
s time configured here, an alarm will be issued. If the monitored value falls

2 Yes The control unit automatically clears the alarm if the fault condition is no
longer detected.
[No] The control unit does not automatically reset the alarm when the fault condi‐
tion is no longer detected.
The alarm must be acknowledged and reset by manually pressing the appro‐
priate buttons or by activating the LogicsManager output "External acknowl‐
edgement" (via a discrete input or via an interface).
2 Yes Monitoring for fault conditions is not performed until engine delayed moni‐
toring is enabled. The engine monitoring delay time (param‐
eter
parameters assigned this delay.
[No] Monitoring for this fault condition is continuously enabled regardless of engine
speed.
