Freedom units produced prior to serial #100,000 have temperature compensation only
for warm or cool environments. The temperature setup sets the voltages as per below:

TOGGLE DISPLAY BETWEEN AHR AND KWHR
DEFAULT OFF = Ah DISPLAY MODE
ON = Ah/kWh ALTERNATING DISPLAY MODE
When this function is selected the A hrs display alternates between the normal amp-
hour mode and the kilowatt-hour counter that the LINK 2000 uses to determine if 100%
of the energy consumed from the battery has been returned. A recalculation of the CEF is
not permitted unless this counter is greater than 0.00 kWh. This counter counts down during
discharge and the kilowatt hours consumed are displayed with a negative number. During
charging it counts back up with 100% efficiency. Not allowing a recalculation of the CEF
and an Ah reset until a positive number is in the counter ensures that there will not be
a premature reset. See page 21 for conditions required for a recalculation of the CEF and
an Ah reset.

ALTERNATIVE ENERGY MODE
DEFAULT: OFF
ON = USE ALTERNATIVE ENERGY DEFAULTS
Turn this mode on if your Link 2000 is used in Alternative Energy Systems.
This function 1) reduces the time necessary to satisfy the charged parameters from five
minutes to one minute; 2) sets Batt #2 discharge floor to 100%; 3) prevents Batt #2 from
doing Ah resets; 4) changes Charged V parameter to 13.5 V (27 V). If you're using a semi-
mechanical photovoltaic controller, we strongly suggest you also consider changing
Charged Current to 4%.

MANUALLY SET CEF (NOT RECOMMENDED)
DEFAULT OFF = AUTO RECALCULATION OF CEF
DISPLAY = A87 OR A90 (DEPENDS ON BATTERY TYPE)
RANGE = 65–99 STEP = 1
Allows manual set up of CEF (Charge Efficiency Factor). Default display A87 or
A90 (depending on battery type selected—see F02) indicates automatic CEF recalculation
feature. Returning to A87 or A90 from a user CEF restores the automatic CEF feature.
If a user-setup CEF has been selected it will appear as a U## ( U preceding a number) in
the DATA mode—see page 15. A different CEF may be set up for each battery; only the
selected battery's CEF will be changed.
F07 - SET TEMPERATURE COEFFICIENT
DEFAULT = 0.5 RANGE = 0.1–0.9 STEP = 0.1
This factor compensates for capacity change with temperature. Typical value 0.5%
Capacity/°C. This coefficient must be supplied by the battery manufacturer. The default
value is typical for lead acid liquid or gelled batteries. Normally this value is not changed.
