PROBLEM DESCRIPTION
Over temperat 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
AC low The AC mains voltage is lower than 207 Vac (mod. SBC 1450 NRG+ HR, SBC 1950 NRG+ HR, SBC 2450 NRG+ HR)
or 108 Vac (SBC 1100 NRG+ FR, SBC 1200 NRG+ FR).
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
207 Vac (mod. SBC 1450 NRG+ HR, SBC 1950 NRG+ HR HR, SBC 2450 NRG+ HR)
or 108 Vac (mod. SBC 1100 NRG+ FR, SBC 1200 NRG+ FR).
AC fail The AC mains voltage is lower than 161 Vac (mod. SBC 1450 NRG+ HR, SBC 1950 NRG+ HR HR, SBC 2450 NRG+ HR)
or 83 Vac (SBC 1100 NRG+ FR, SBC 1200 NRG+ FR).
The battery charger suspends the ouput power supply, which will start again once the mains voltage go back to a higher
value than 161 Vac (mod. SBC 1450 NRG+ HR, SBC 1950 NRG+ HR HR, SBC 2450 NRG+ HR)
or 83 Vac (mod. SBC 1100 NRG+ FR, SBC 1200 NRG+ FR).
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 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 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
CAN error The system detected some communication errors on the CAN bus.
If this message appears frequently, check the CAN network wiring.

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.
