Battery charger fault codes
A01: LOGIC FAILURE #1
Blocking alarm. This error occurs whenever the battery
current exceeds the current setpoint plus a given safety
limit for more than 10 seconds, which means that the cur-
rent is out of control.
Troubleshooting: try to turn off and turn on the charger. If
the problem persists, the problem may be in the logic
board or the shunt resistor. Change the product or contact
Zivan.
A02: CANBUS KO
- CB, CB9, QE, QE9
Temporary alarm. This error may be detected in a MAS-
TER-SLAVE connection if the MASTER does not receive
any message from the SLAVES for a certain period of time
(around 8 seconds) or, likewise, if a SLAVE no longer
receives any messages from the MASTER. Moreover, QE,
QE9 products may detect this error if they do not receive
any message from the external device. When this alarm is
shown in ZnCanConsole, it is also followed by a number
or an acronym that is used by Zivan to understand how
the alarm was generated. If the display is present, this
alarm will be shown in the data roll, after the charged
amperehours (or eventually the number of slave devices,
if there are any). When the error clears, the charger
resumes the charge from the point it wa interrupted.
- CB6, QE6:
Temporary alarm. This alarm may be detected only in
some products designed to work in conjunction with a
PLC when the charger does not receive any message
from it.
Troubleshooting: make sure that the CANBUS wiring is
done properly and that the relative connectors are tightly
connected together.
A03: WATCHDOG
Blocking alarm. This error occurs whenever the micropro-
cessor of the logic board fails to complete properly its
internal tasks within a certain period of time, typically
because it has encountered an unpredictable state.
Troubleshooting: try to turn off and turn on the charger. If
the problem persists, the problem is in the logic board.
Change the product or contact Zivan.
A04: OPEN OUTPUT (SG6, QE6) – obsolete alarm: no
longer implemented in latest firmware versions
Temporary alarm.
A05: HIGH TEMP. BATT. (NG1/NG3, G9, QL) – BATTERY
TEMP. (SG6, QE6)
- CB, CB9:
Temporary alarm. This error occurs whenever the battery
temperature exceeds 55 °C. This control is performed by a
MASTER or STANDALONE charger only. When this alarm
is reached, the charger stops and waits for the tempera-
ture to drop below 50 °C before resuming the charge from
the point it was interrupted.
- CB6, QE6:
Temporary alarm. This error occurs whenever the battery
temperature falls below -20°C or when it exceeds the tem-
perature set by the STOP BATT. TEMP. parameter. In this
case, the charger stops and waits for the temperature to
below the temperature given by STOP BATT. TEMP – 10
°C. When this happens, the charger resumes the charge
from the point it was interrupted.
Troubleshooting: if the problem persists even when the
battery temperature is below the threshold temperature,
the sensor may have some defects. You may try (at your
own risk) to remove the temperature sensor and turn off
and turn on the battery charger. Contact Zivan.
A06: MISSING PHASE (CB, CB9, QE9, QL)
Temporary alarm. This error occurs whenever the charger
detects the absence of one of the three input phases for at
least 2.5 seconds (5 seconds in QE9 products). This con-
trol is performed only in 3-phase systems. When this
alarm condition is met, the charger stops and waits for the
error to clear before restarting the charge from the point it
was interrupted.
Troubleshooting: check for the three phases to be con-
nected to the charger. Make sure that all the three power
fuses are not broken. Verify whether the neutral is wrongly
connected to one of the three phases. If problem persists,
change product or contact Zivan.
A07: OVERCURRENT
Temporary alarm. This error occurs whenever the charger
detects an anomalous current absorption in the primary
section. When this happens, the charger stops and waits
for the primary current for drop below a safety threshold.
After that, the charger waits for another 2.5 seconds (the
fan will restart in 1.5 seconds), then it clears the alarm and
tries to resume the charge from the point it was inter-
rupted.
Troubleshooting: wait for the charger to try the restarting
procedure. If the problem persists, the problem may be in
the primary section. Change the product or contact Zivan
