4.5.6.14 Battery Undervoltage (Level 1 & 2)
General notes
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.
If this protective function is triggered, the display indicates "Bat. undervoltage 1" or
"Bat. undervoltage 2" and the logical command variable "08.03" or "08.04" will be
enabled.

Monitoring
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.
3504

Limit
2
8.0 to 42.0 V
3504: [24.0 V]
3510: [20.0 V]
(Hysteresis: 0.1 V)
(Reset Delay: 1s)
The threshold values that are to
be monitored are defined here.
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 initiated.
Notes
The default monitoring limit for
battery undervoltage is 24 Vdc
after 60 seconds.
This is because in normal
operation the terminal voltage is
approximately 26 Vdc (alternator
charged battery).

3511
Delay
2
0.02 to 99.99 s
3505: [60.00 s]
3511: [10.00 s]
If the battery voltage falls below
the threshold value for the delay
time configured here, an alarm
will be issued.
