Trouble Shooting - A.T.I.B. 3N Série Manuel D'utilisation Et D'entretien

Here is a list of information that starting from LEDs signals or coming from the "single parameter/Guide" offers some
typical faults.
ATTENTION: chargers can provide slightly different information depending on the fact they are single or three phase.
These depends on components presents in the electrical circuit

Without the AC network , the display switches to standby mode ( -___ ) after one minute .
Pressing any key it turns on for another minute .

6. TROUBLE SHOOTING

Display
DC is missing: Battery is not connected to the charge or voltage is very low
(7V). Vac mains might be present.
-- The fuse protecting the diode bridge is burnt.
the battery plug is damaged , a battery cable is interrupted
Electronic board not powered or faulty.
DC under voltage: Battery is connected to the charger but voltage is below
bAt
min threshold (1,7Vel o 85% Vnom).
AC Mains is missing: Charger has attempted to start charging but detect that
Vac Mains is missing. Please check input plug connection, the main switch of the
cur
grid and related input AC fuses. When AC power is back the system restarts
automatically
AC and DC are missing: Both battery and input Vac Main are missing.
If Vac is present problem is connected to the auxiliary transformer or to its
connections.
--
The fuse protecting the diode bridge is burnt.
the battery plug is damaged , a battery cable is interrupted
The electronic card is not powered or is faulty
DC under voltage: Battery voltage is present, but the battery "is not"
bAt
connected to the charger or below min threshold (1,7Vel o 85% Vnom).
AC Mains is missing: Battery is present but Vac is missing. Please check input
Stop plug connection, the main switch of the grid and related input AC fuses. Problem
is connected to the auxiliary transformer or to its connections.
Stop : Charger has been stopped through the push off button placed on the
Stop
front door.
ATTENTION: Charger is supplying current but nominal voltage has not yet
bAt1 reached (between 85-100% Vnom). Battery capacity is probably too big (Ah).
After some minutes the charger might stop automatically for over-current alarm
Under current: The current in the battery is below the minimum threshold (2-
3 A). Charger will try to restart every minutes on.
1) There might be a possible bad contact or a connection problem .
cur Check AC mains plug connection, the main switch of the electric line and the
input AC fuses
2) Battery is sulphated
3) The ammeter sensor or its connection cables are damaged.
Thermal fault: If the power transformer is hot one or more thermal probes are
open ( tEr ) or preventive intervention of the board to reduce the temperature
of the power transformer ( TERC ) .
tEr
When the temperature drops probes are restored and the system restarts .
tErc
If the transformer is cold check the electrical circuit of the probe and of the stop
button (see the wiring diagrams ) . One or more probes on the transformer are
not working or possible damage of related wirings
TiME : Maximum charging time Phase 1has been exceeded: 11h (<2,4Vel)
t_t2 : Maximum charging time Phase 2 has been exceeded: 9h (>2,4Vel)
tout : Maximum global charging time has been exceeded: 18h (total)
Any of these alarms can be caused by following cases:
TiME
1) AC Mains is too low
2) Vac tapping on power transformer is not in the correct position
3) Battery is not suitable: too big or damaged. Battery does not reach 2,4Vel
4) Wrong card setting
