3.5 HISTORICAL DATA
Press INFO shortly to scroll through the levels as
described below. When no button is touched during 20
seconds, or if you hold SOURCE pressed for at least two
seconds, the display returns to the initial readings.
See section 5.2 if you want to reset the below
mentioned historical data.
Number of completed cycles
Total number charging cycles that were
entirely completed, i.e. from bulk to float.
See section 3.4 for detailed information of
the three step charge algorithm.
Number of aborted cycles
Each time the charge cycle was not entirely
finished, this counter is increased by 1.
Operation of the Chargemaster might be
interrupted because of AC grid failure. A
large number of aborted cycles may indicate
too short charging periods or an undersized
charging system. Be aware that incomplete
charges can reduce the expected lifetime of
your batteries dramatically.
Total Ampere hours charged
Total amount of charged Amphours or kAh
for battery bank 1, 2 or 3 (press SOURCE to
select the battery bank).
Total runtime in charger mode
Total number of hours that the
Chargemaster was charging.
Highest AC input voltage
Here the highest recorded AC input voltage
is shown. To avoid damaging the charger
this value may never be higher than the
absolute maximum AC-input voltage (see
figure 9). High AC-input voltages are often
caused by generator sets that have a poor
voltage regulation. Have your electrical
installation examined by a qualified installer
if this value is higher than 260VAC.
Number of temperature shutdowns
If the internal temperature of the
Chargemaster is too high, it shuts down
automatically. After cooling down, the
Chargemaster will switch on again. A large
number of temperature shutdowns might
indicate too hot environmental conditions or
bad cooling due to obstruction of the air flow
around the charger.
Number of low DC voltage shutdowns
If the battery voltage is too low the
ChargeMaster will limit the charge current to
25% of the nominal charge current (see
specifications). This counter shows the
number of times that this happened. Have
your electrical installation examined by a
qualified installer if this has happened more
than once.
Number of high DC voltage shutdowns
Also if the battery voltage is too high the
ChargeMaster shuts down automatically.
This counter shows the number of times that
this happened. Have your electrical
installation examined by a qualified installer
if this has happened more than once.
Number of high AC voltage shutdowns
This value shows the number of times that
the Chargemaster was shut off due to too
high AC input voltage. High AC-input
voltages are often caused by generator sets
that have a poor voltage regulation. Have
your electrical installation examined by a
qualified installer if this has happened more
than once.
Number of low AC voltage shutdowns
Number of times that the Chargemaster was
shut off due to too low AC input voltage (see
figure 9). Low AC-input voltages may be
caused by generator sets that have a poor
voltage regulation or by thin AC-wiring. In
some marinas or camping sites the AC
power supply sometimes drops too low
when there is a large demand of electric
power.
