NOTIFICATION SIGNS - MAINTENANCE
MAINTENANCE
The battery charger does not need any maintenance. To ensure optimum performance from the equipment, once a year
check the cables and the electrical connections.

MESSAGE DESCRIPTION
1
Output short circuit
or overload
Check the output wiring, the battery bank and the equipment connected to the battery charger.
PROBLEMS WITH AUTOMATIC RESET
The notifications of the problems with automatic reset will no longer be displayed as soon as the condition which caused
the problem disappears.
The RED LED will come on steadily and an error will be displayed in the LCD terminal (optional) to signal the following errors
PROBLEM DESCRIPTION
Over temperature The ambient temperature where the battery charger is installed exceeds the max allowable threshold for regular
operation.
Check the installation environment and its placement.
Blocked fan One of the two cooling fans is blocked due to external causes (foreign bodies which block the blades movement) or for
malfunctionig. The battery charger limits the value of the maximum output current.
The problem requires a check by a Quick
®
service center.
AC low The AC mains voltage is lower than 108 Vac.
The battery charger will carry out a reduction of the maximum output current by supplying as maximum value the 70%
of the output maximum rated current, thus reducing the current absorption from the AC mains.
The supply of the maximum output current will start again once the network voltage increase back to a higher value
than 108 Vac.
AC fail The AC mains voltage is lower 83 Vac.
The battery charger suspends the ouput power supply, which will start again once the mains voltage go back to a higher
value than 83 Vac.
Cold battery The temperature measured by the sensor or the optional sensors of the batteries is lower than -15°C.
The battery charger suspends the output power supply which will start again once the temperature will go back to a
higher value than -15°C.
Hot battery The temperature measured by the sensor or the optional sensors of the batteries is highter than +50°C.
The battery charger suspends the output power supply which will start again once the temperature will go back to a
lower value than +50°C.
Sensor fault Failure of one of the two battery charger’s internal temperature sensors. The battery charger limits, if necessary, the
maximum output current value.
The problem requires a check by a Quick ® service center.
CAN error The system detected some communication errors on the CAN BUS. If this message appears frequently, check the CAN
network wiring.
