[Default]
2 0.02 to 99.99 s If the monitored battery voltage exceeds the threshold value for the delay time
configured here, an alarm will be issued.
3455: [5.00 s]
3461: [1.00 s]
Notes
If the monitored battery voltage falls below the threshold (minus the hyste‐
resis) before the delay expires the time will be reset.
2 Class A/B/C/D/ Each limit may be assigned an independent alarm class that specifies what

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.
There are two battery undervoltage alarm levels available in the
control. Both alarms are definite time alarms. Monitoring of the
voltage is done in two steps.
