Lowest detected DC voltage
Shows the lowest DC-voltage that was
recorded for battery bank 1, 2 or 3 (press
SOURCE to select the battery bank). This
value should never be below the final
discharge voltage as specified by the battery
manufacturer.
Highest detected DC-voltage
Shows the highest DC-voltage that was
recorded for battery bank 1, 2 or 3 (press
SOURCE to select the battery bank) This
voltage should never be higher than the
maximum charging voltage as specified by
the battery manufacturer. Too high voltages
may also damage the connected DC-loads.

Lock - Unlock
To protect the ChargeMaster against
unintended adjustment of set points, the lock
mode is activated every time you leave the
Settings menu. When activated (“ON”), it is
not possible to change settings.
Default setting: ON
Press SOURCE to toggle the lock mode.
3.6 MASTERBUS (OPTIONAL)
The Chargemaster is compatible with the MasterBus
network: a fully decentralized data network for
communication between the different Mastervolt system
devices such as the inverter, battery charger, generator,
batteries and many more. See chapter 6 for details.
3.7 MAINTENANCE
No specific maintenance to the Chargemaster is required.
Examine your electrical installation on a regular base, at
least once a year. Defects such as loose connections,
burnt wiring etc. must be corrected immediately.
If necessary, use a soft clean cloth to clean cabinet of the
Chargemaster. Never use any liquids, acids and/or
scourers.
3.8 FAILURES
The Chargemaster is protected against overload, short
circuit, over heating and under and over voltage. If a fault
condition occurs, text FAILURE is shown on the LCD-
display. The cause of the failure is displayed by means of
an error code. See section 7.2 for explanation.
CAUTION!
The Chargemaster is not protected against
reversing polarity of the DC-output and
serious over voltage (>265VAC) on the AC-
input .
As long as FAILURE isn’t shown, no failure is
detected: the Chargemaster is operating
normally!
