IUa

7.1.2.

Stage 1 Current

Percentage of the nominal charger
current (set in the configuration) that
is used for the bulk charge stage,
normally set to 100%.

Stage 1+2 Timeout

Maximum total elapsed time in minutes
that the charger will deliver charge to
the battery. In an IU profile it is
normally required to limit the total
time in stage 1&2

Stage 2 Voltage

Setting for the constant voltage stage,
set in accordance with the battery
technology depending on when a
particular battery type starts to gas.
This is an important voltage and should
take into account temperature, ideally
with active compensation of the
battery voltage with the measured
battery temperature.

Stage 2 Timeout

This gives the ability to limit the
maximum time the charger will stay in
the constant voltage stage of the cycle.
Normally set to 0 with the combined
Stage1+2 Timeout being used.

Minimum Current

Once the charge current in Stage 2
drops below this value the charge cycle
will terminate and the battery ready
light will be illuminated. This gives the
ability to promptly terminate the
charge should the battery be in a high
state of charge without having to wait
for the Stage1+2 timeout before
indicating the battery is ready.

EQ/Refresh Current

The percentage of the nominal charger
current (set in the configuration) that
is used for the refresh, second constant
current stage, actual setting depends
on the battery type and application.

EQ/Refresh Duration

The duration of the Refresh charge, be
it only constant current or a
combination of constant current and
constant voltage.

EQ/Refresh Max Cell Voltage

The maximum charger output voltage
during the refresh charge. Can either
be a trip or a second constant voltage
stage depending on the setting of
EQ/Refresh Constant Voltage.

Stage 1 Timeout

Gives the ability to have a separate
timeout for Stage1, normally not used.

Auto EQ/Refresh After

Time that the battery needs to remain
connected to the charger to initiate a
Refresh cycle. The actual setting
depends on the battery and the
application.

EQ/Refresh Lockout

Gives additional protection against a
Refresh charge starting without
adequate battery cool down time.

Temp Comp Factor

Factor used to adjust the chargers
voltage setting to allow for different
battery temperature in
mV/(°C/°F)/cell. In high rate
applications the setting of temperature
compensation is quite important and
may need to be adjusted to suit the
battery type and application.

Auto EQ/Refresh options

Some profile type selections allow the
following Auto Equalize options. Auto
Equalize must be enabled in the
Configuration tab.

Profile Auto Equalise Enable

When selected, the equalize options
are enabled, operating with the
EQ/Refresh Current, EQ/Refresh
Duration, EQ/Refresh Lockout and Auto
EQ/Refresh After parameters.

Bulk Charge Only, Full Charge
on Equalise only

Select when opportunity charging using
battery modules. Initiates a full charge
whenever an equalise charge is set to
occur.
