Needed interface / component: SHC 312 / SHC 612 / EM-box.
A maximum of 4 batteries or battery banks are displayed per page. Further batteries
can be displayed on subsequent pages. The pages can be changed by pressing the
arrow buttons at the top.
If an active SHC Shunt is connected, the available capacity is shown by the height of
the coloured bar section in the appropriate battery symbol.
The available capacity is shown as a percentage along with the voltage and
charging/discharging current. By tapping the battery symbol, you can switch between
displaying available capacity, the remaining time to the capacity alarm or estimated
time of charging, and – if a temperature sensor is connected at the shunt - the
temperature.
The current is displayed dynamically to 3 digits (e.g. 120A, 45,0 A or 0.01A). A minus
sign before the amperage reading means that the battery is discharging. If no minus
sign is present, then the battery will be charging at the amperage shown
.
The blue area shows the useable capacity before the alarm threshold. The dark blue
area shows the theoretically available capacity until the battery is completely
discharged (deep discharge). A deep discharge should be strictly avoided, as the
battery will almost certainly be permanently damaged. If the shunt SHC determines
that the point of deep discharge has arrived sooner than it should normally be (e.g. by
aging), the unusable part will be displayed in the dark grey area.
Appears in the battery symbol the
message "Not synchronized" then the
shunt SHC was restarted and the display
of the battery capacity does not yet
correspond to the true capacity level. To
synchronize the shunt SHC the
connected battery bank has to be fully
charged with a battery charger. If the
battery is fully charged the message
extinguishes automatically.
If the capacity falls below a set threshold a warning appears on the display. The
remaining capacity is shown in orange and the battery symbol outline is shown red.
If the battery is nearly empty or deeply discharged or if an over-voltage occurs (battery
voltage > 15 V) a warning appears. The remaining capacity is shown in orange and the
battery symbol outline is shown red.
An additional voltage can be supervised (e.g. the voltage of a starter battery). This
voltage will be shown by a symbol with white outline and no colour, together with the
measured voltage. If this voltage falls below the adjusted alarm threshold the battery
symbol is shown red.
