Configuration within MasterAdjust
First, ensure both the Mass Charger and the MasterBus Interface are both powered and connected, along with a
MasterBus USB in te r fac e , to th e Ma ste rBus network. If a ll o f this has been done th e Ma ss C har g er an d th e MBI w ill b e
listed, with any other MasterBus Compatible devices also connected to the network, in the left column on the
MasterAdjust Screen.
Charger On/Off Control
1. Select the MBI (default name: “INT MBI”) from the list of MasterBus devices, navigate to the ‘Events’ tab and
create a new event using the following se tt ings to allow a control signal from CZone™ to M asterBus to contr o l the
Mass Charger’s On/Off state.
2. Select the Mass Charger (e.g. CHG Mass Charger) from the list of MasterBus devices and create a new event
using the below settings to allow the Mass Charger’s On/Off status to be fed back to CZone™ as a
feedback/’systems in operation’ signal.
Note: For every control even t progr ammed from CZ one™ to M asterBu s, a correspon ding feedb ack even t needs to
also be programmed.

DC Monitoring
To allow AC/DC data, as well as the inverter and charger state (e.g. Bulk, Float, etc.) to be shown in CZone™, the
individual MasterBus data items (voltage, current, state of charge, etc.) need to be selected in order to populate
standard NMEA2000 AC/DC/Charger Status PGN messages which are to be transmitted and monitored within the
NMEA2000/CZone™ network. Each of these sets of AC/DC/Charger Status data items are configured within the MBI
Configuration tab using data item index values retrieved from the Monitoring tabs of devices presenting the
information.
Charger Status
Select the MBI (INT MBI) from the list of MasterBus devices and go to the Configuration tab.
1. In the first available Metering field (in this example Metering 1) click on the ‘Type’ dropdown and select
Inv/Charger Status. (The same data type is used for both Charger and Inverter Status items)
2. Click the ‘Device’ dropdown and select the Mass Charger (e.g. CHG Mass Charger). This indicates that the data
item being configured will come from the Mass Charger.
3. Click the ‘Charger status’ dropdown and select ‘Monitoring’. This indicates that the data item being configured will
come from the Monitoring tab of the Mass Charger.
4. To figure out the correct ‘Charger statu s’ inde x to ente r, clic k on the ‘Mass Charger’ in the device list on the left of
the screen. Navigate to the ‘Monitoring’ tab. Hover the mouse pointer over the Charger State parameter. The
Index Number will appear beside the mouse pointer – note this number down.
Return to the ‘Configuration’ tab of the MBI and en ter the inde x number just noted down in to the ‘Charger st atus’
number box.

Configuration within CZone™
Open the CZone™ Configuration Tool.
Controlling the Charger
The control mechanism between CZone™ and MasterBus functions by configuring virtual loads (MasterBus Event
Sources) within CZone™ which subsequently function as virtual switches (Control to MB) within MasterBus. To control
one of these virtual switches, a load must first be configured within CZone™ and programm ed to turn on/off within a
CZone™ circuit. The corresponding switch within MasterBus will then follow the state (on=closed, off=open) of this
virtual load (MasterBus Event Source).
The virtual load (MasterBus Event Source) can be configured within CZone™ as follows.
Ensure that the MBI has been added to the configuration within the ‘Modules’ tab.
Charger Load Configuratio n
1. Go to the ‘Loads’ tab and then click ‘Add’.
2. Enter a name for the virtual load/MasterBus Event Source (e.g. “Charger Control”).
3. Click the ‘Module’ dropdown and select the ‘MBI’ previously added in the Modules tab for this example we are
using ‘MBI 01’).
4. Click the ‘Channel’ dropdown and select the Event Source number configured above in MasterAdjust to control the
charger On/Off state (for this example we are using ‘Event Source 1’).
5. Tick the box ‘Follow MB Target State’ checkbox. This ensures that the virtual load (Event Source) on/off state
follows the on/off state of the Mass Charger. This is important when the Mass C harger is also controlled fr om
outside of CZone™ – if the virtual load remains off when the Mass Charger is turned on externally, turning the
virtual load off in order to turn the charger off will have no effect. The virtual load (Event Source) state must
therefore follow the target device state in order for on/off commands from the user to always function correctly.
6. Tick the ‘Use MB Target Systems-On’ checkbox. This ensures that the systems in operation indicators for any
circuits in which this virtual load are used will follow the on/off state of the target MasterBus device (which needs
configured in MasterAdjust to be fed back to the MBI, as above). If this checkbox is not ticked, the systems in
operation for the virtual load will follow the state of the virtual load, which may not correctly indicate the state of
the target device (this would be like indicat ing the state of a switch rather than indicating the state of what the
switch controls).
The advantage to having this box not ticked is that the systems in operation feeds back instantly, which can be
preferable when there is a significant delay in the feedback event from the target device within MasterBus. For
the Mass Charger there is a delay of 2-3 seconds in the systems in operation feedback from the charger, so it may
in fact be preferable to leave the ‘Use MB Target Systems-On’ checkbox not ticked.

1. Go to the ‘Circuits’ tab. Under ‘Configured Circuits’ select ‘Add’. Create a standard circuit, in this example called
‘Charger Control’.
2. Under ‘Circuit Controls’ set up an ‘All Display Interfaces’ switch as a Double Throw Momentary On/Off.
Note: If control is only required within the CZone™ ‘Inverter/Charger Con trol’ page and not within the standard
‘Circuits’ menu, there is no need to add this ‘All Display Interfaces’ circuit controller.

a single diagram within the CZone™ Inverters/Chargers Control menu.
1. Go to the ‘Mastervolt’ tab and then under the ‘Configured Mastervolt Inverter/Chargers’ section click ‘Add’.
2. Enter a name for the device (e.g. ‘Mass Charger’).
3. Click the ‘Inverter/Charge Status Metering Item’ dropdown and select the metering item number used for the
Inverter/Charger status configured in the MasterAdjust section above (i.e. Metering 1).
4. Click the ‘Device Type’ dropdown and select ‘Mass Charger’.
5. Click the ‘Charger Instance’ dr opdown an d select a un ique NMEA 2000 Ch arger In stan ce (these in stance nu mbers
must be different for each charger added to the system).
6. Click the ‘Inverter Instance’ dropdown and select ‘None / Charger Only’.
7. Click the ‘Inverter Output AC Instance’ dropdown and select the preconfigured AC Meter item (i.e. MassCombi AC
Out)
8. Click the ‘Battery/DC Instanc e 1’ dropdown and selec t the precon figured DC M eter ite m to be associated w ith this
device on the CZone™ Inverters/Chargers Control page. In this example we will use the ‘MassCharger’ DC
Metering item we configured earlier. For charger with multiple DC outputs up to three DC Metering items can be
associated – in this example we will only use one.
9. Click the ‘Charger Control Circuit’ dropdown and select the ‘Charger Control’ circuit configured above (i.e. Charger
