LOCAL USER INTERFACE
The status display at the front side of the ChargeMaster
Plus enables you to control the charger and monitor the
charging process.
3.2.1
Switching on / stand-by
The ChargeMaster Plus is activated by holding the MODE
switch (see figure 2) pressed for approx. 3 seconds. The
MODE LED will illuminate green. If necessary and if AC
power is available, the ChargeMaster Plus will start to
charge the batteries.
Once switched on, the ChargeMaster Plus
automatically resumes operation after it was
disconnected from an AC-source temporarily.
By holding the MODE switch pressed again for approx. 3
seconds, the ChargeMaster Plus will switch back to stand-
by: the ChargeMaster Plus stops and the MODE LED
illuminates red.
WARNING
Switching the ChargeMaster Plus
to “stand-
by” does not cut off the connection to the
batteries or the AC-source. This means that
voltages are still present inside the apparatus.

The ChargeMaster Plus can also be operated

MasterBus remote control panel. See section
