7.2.3 Troubleshooting tank sensors
If the tank monitor shows wrong values or “---“, first check that the sensor is connected
properly. Next check the wiring between the sensor and the tank interface CMT2, as
this has shown to be the main source of errors.
If the shown values are obviously incorrect, check that the voltage of the power supply
of the CMT2 and the sensors is above 10V.
7.3 Submenu Energy
Needed interface/component: SHL312 / EM-box
This menu shows the energy balance of the on board DC system. Depending on the
deployment of shunts SHL or an EM-box, the current flow can be analysed in detail.
The Energy page shows, which energy sources are feeding the system, and at what
amperage, and which loads are taking energy and at what rate. It is also possible to
see if the batteries are being charged or discharged, and arrows show the direction of
the current flow.
The charging sources are shown in the
upper part of the display, the loads in
the lower part. A “Combi” Inverter/
Charger will appear on the bottom line
and will show amps being charged or
consumed, but will show only
accumulative charging Ah.
In this menu, all batteries are combined
and shown as one battery in order to
give a clear overview. A detailed
analysis of the battery systems can be
obtained by opening the battery page.
7.3.1 Features Energy
By touching the symbols, the display can be switched to show the accumulative
Ah consumed or delivered since the counter was last reset.
If an ACE charger is connected to the network, there is more information available
which will appear in a new window after tapping the symbol “Charger”.
The availability of this additional information in shown by an “i” in the upper right corner
of the charger symbol.
