[Default]
2 [On] Undervoltage monitoring of the battery voltage is carried out according to the
following parameters. Both values may be configured independent from each
other (prerequisite: Level 1 > Level 2).
Off Monitoring is disabled for Level 1 limit and/or Level 2 limit.
2 8.0 to 42.0 V The threshold values that are to be monitored are defined here.
3404: [24.0 V] If the monitored battery voltage reaches or falls below this value for at least
the delay time without interruption, the action specified by the alarm class is
3510: [20.0 V]
initiated.
Notes
The default monitoring limit for battery undervoltage is 24 Vdc after 60 sec‐
onds.
This is because in normal operation the terminal voltage is approximately
26 Vdc (alternator charged battery).
2 0.02 to 99.99 s If the battery voltage falls below the threshold value for the delay time config‐
ured here, an alarm will be issued.
3405: [60.00 s]
3511: [10.00 s]
Notes
If the battery voltage exceeds the threshold (plus the hysteresis) again 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
E/F/Control action should be taken when the limit is surpassed.

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.
The multi-unit parameter alignment functionality requires that the
relevant parameters are all configured identically at all participating
units.
