Alarms
Code
Alarm text
Description
Recommended actions
1
Low battery voltage
Battery voltage below low limit.
Defined by charging curve.
Check battery for damages cells.
Check charging parameter cell
count.
2
High battery voltage
Battery voltage above charging
algorithm high limit. Defined in
charging curve.
Check charging parameter C
ells
.
3
Time limit exceeded
Time limit defined in charging
curve exceeded.
Check battery for damaged cells.
4
Ah limit exceeded
Ah limit defined in charging curve
exceeded.
Check battery for damaged cells.
Check
charging
parameter
Capacity
5
Invalid charging
parameters.
Charging parameters not set
correctly in charger.
Check charging parameters in
menu.
6
Charger not in upright
position
Charger is not in upright position. Place the charger in vertical
position.
7
High battery voltage power
unit shut off
Battery voltage above charger high
limit. Defined in charging curve.
Check battery voltage.
Check charging parameter C
ells
.
8
Battery error
General battery charging error.
Check battery.
Check charging curve specification
for error details.
9
Low air pump pressure
The monitored air pump pressure
is below 3 kPa.
Check air pump installation for
leaks.
10
High air pump pressure
The monitored air pump pressure
is above 12 kPa.
Check air pump installation for
blockings.
17
Mains feed phase error
A phase is missing from mains
supply.
The charger has been restarted
more than three times within a
time period.
Check mains supply fuses.
If the failure cause is restored the
alarm will reset automatically.
Wait 1 minute for the alarm to
reset.
18
Regulator error
Error in power unit control.
Current has been below 1 A for
one minute and set current is
greater than 1 A. Error is triggered
the third time this happens during
one charging cycle.
Check secondary side fuse.
Make sure power unit parameter
is according to used power unit.
19
Low charger temp
Heat sink temperature is below
low limit.
Place the charger in heated
environment.
20
High charger temp,
derating output
Heat sink temperature is above
high limit. This alarm is trigged
when the temperature reaches the
derate end threshold and is kept
active until the derate start
threshold is reached.
Check cooling fans.
21
Low board temp
