A08: HIGH TEMPERATURE (CB) – HIGH TEMP (CB6,
CB9, QE, QE9, QE6, QL)
- CB, CB9, QE, QE9, QL:
Blocking alarm. This error occurs whenever the internal
temperature of the battery charger, in the power compo-
nents section, is too high. When this happens, ZnCanCon-
sole will show also which PTC sensor has detected the
problem (identified by a number – note: some products
have only one PTC sensor
- CB6, QE6:
Temporary alarm. The alarm is detected in the same way
as above, except the user can manually control this alarm
through TEMP. WAR LEVEL and TEMP. ALL LEVEL. The
alarm is detected with temperatures above TEMP. ALL
LEVEL and it causes the charger to stop. The alarm is
cleared when the temperature falls below the temperature
given by TEMP. WAR LEVEL – 9°C. In this case, the char-
ger resumes the charge from the point it was interrupted.
Troubleshooting: check the fans to work properly (if your
product is ventilated). Turn off the charger and remove any
obstruction in the grid of the cover. If the problem persists,
the problem may be in the power section. Change the
product or contact Zivan.
A09: BATT. DISCONNECT (QE6 only)
Temporary alarm. Our chargers are provided with a spe-
cial 2-channels battery voltage reading system. This error
occurs whenever the readings from the two channels dif-
fer from each other exceedingly, meaning that for some
reason the charger no longer has a correct voltage read-
ing. This alarm has a blocking behaviour in order to pro-
tect the battery from being charged improperly. When this
alarm clears, the charger resumes the charge from the
point it was interrupted.
Troubleshooting: turn off and turn the charger. If the prob-
lem persists, check for the firmware version of your prod-
uct and eventually update it. In some of the latest releases
(CB - 0.24, CB9 - 0.44, or higher) the tolerance between
the two channels readings has been relaxed. If this is not
your case, change the product or contact Zivan.
A10: TIMEOUT (CB, QL) – TIMEOUT PHASE #1 (CB9)
Blocking alarm. This error occurs when the charger
reaches the phase 1 timeout. This time is calculated as the
total charging time (which in its turn depends on the pro-
grammed capacity) minus two hours, except when this
timeout is manually programmed via the ZnCanConsole.
Troubleshooting: in case of programming via ZnCanCon-
sole, ensure that the special adjustment TIME PH. #1 MIN.
is programmed correctly. As a reference, you should use
the rule given above. If you happen to have the special
adjustment setting completely messed, you can restore
the factory setting by using the values supplied with Tab.2.
Check also that the programmed capacity is adequate to
the battery capacity (specifically, it doesn’t have to be infe-
rior)
A10: NO MAINS PRESENCE (QE6 only)
Temporary alarm. This error occurs when the charger is
not able to detect the mains voltage. When this happens,
the charger stops. Then, if the charger detects the mains
voltage for 2 consecutive seconds, the charge resumes
from the point it was interrupted
Troubleshooting: check the mains voltage. Try to turn off
and turn on the charger. If the problem persists. Change
the product or contact Zivan.
A11: TIMEOUT (CB6 only)
Blocking alarm. This alarm occurs in the same way as
described above for CB products, except that it works for
all the phases of the charge.
Troubleshooting: see A10 CB, CB9 and QL products.
A11: DEEP DISCHARGE (G9, QL)
Temporary alarm. This error may be detected at the turn
on if the battery has a voltage included in the 1.5 – 1.7 V/
cell range. When this happens, the charger waits for the
pressure of the MODE button. Once the button is pressed
the charger starts a 72 hours reduced current state
(employing 1/12th of the nominal current), at the end of
the which the programmed charging curve finally starts.
Troubleshooting: push the mode button to enter the
reduced current mode. If the charge doesn’t start, the
problem may be in the MODE button, so check if it is actu-
ally working by trying to program the charger at the turn on
via the button. Change the product or contact Zivan.
A12: OVER DISCHARGE (G9, QL)
Non-blocking alarm. This error may be detected at the
turn on if the battery has a voltage included in the 1.7 – 1.9
V/cell range. This alarm, when detected, will be displayed
only for 2 seconds before the charger actually starts.
Troubleshooting: when using your batteries, make sure
you don’t reach excessive levels of depth of discharge.
