SBS MicroSMART Battery Charger Technical Handbook
5.4.2.
Charger
Run time (h)
Total time in operation since reset of statistic information. The time
is calculated when the power unit is active.
Charged Ah
Totally charged ampere hours since last reset of statistic
information.
Charged kWh
Totally charged kilo watt hours since last reset of statistic
information.
AC OVP
Number of mains over voltage protection (
OVP
) activations. The
OVP
is counting if a main over voltages is detected during charging.
5.5.
Service
The service menu is used to edit or view parameters stored in the charger.
5.5.1.
Charger info
HW S/N
Production serial number of the control board. This number can
also be read on the control board sticker.
Main FW type
Part number of the main microprocessor firmware.
Main FW ver
Version of the main microprocessor firmware.
Radio FW type
Part number of the radio microprocessor firmware.
Radio FW ver
Version of the radio microprocessor firmware.
5.5.2.
Charging param
In the
Charging param
menu parameters used for charging can be edited.
If
Source
is set to
BMU
and a BMU is connected to the charger, the parameters uploaded from
BMU are shown. If these parameters are edited while the BMU is connected new parameters
will be written to the BMU when
Esc
is pressed.
Source
The source of the charging parameters. The possible values are:
•
User def
, user defined parameters in the service menu.
•
BMU
, parameters will be uploaded from the separate product
Battery Monitoring Unit. When battery connected, the charger
will try to communicate with the BMU. This is done in two steps
BMU Init 1 and BMU Init 2. BMU Init 1 takes up to 15 seconds.
If BMU Init 1 fails BMU Init 2 will start. BMU Init2 can take up to
50 seconds. If BMU Init 2 fails a
BMU Init fail
alarm will be shown
and charging stopped.
