F02 - DISPLAY SLEEP
DEFAULT: ON RANGE: ON, OFF
Turns off all lights on the front panel except for the light bar, AC indicator, charging
status lights, and invert and charge status lights.
F03 -
SET OR DISPLAY AMBIENT BATTERY TEMPERATURE
THIS FUNCTION DEPENDS ON THE SETTING OF F16, PAGE 23.
IF F16 IS
ON, F03 DISPLAYS PRESENT BATTERY TEMP. (
O
F.)
This function is only available if your Freedom inverter/charger is equipped
with a Heart Interface TC2+2 temperature sensing unit. Turn off scanning (F01) to
see the reported temperature continously.
After time out, the time indicator light
will blink during this continous
display .
IF F16 IS
OFF, F03 DISPLAYS DECLARED BATTERY TEMP. (
O
F.)
DEFAULT = 70F RANGE = 30-120F STEP = 10F
The
Link 1000
default ambient temperature setting is 70
0
F. The ambient tempera-
ture of the battery may be set up to select the appropriate Charge and Float Voltages for the
Freedom
inverter/charger. The temperature may be set in 10
0
F increments.
Setting up a different value should only be done if the battery operates at a tempera-
ture significantly different from 70
0
F when they are being charged from the
Freedom
Inverter/Charger. If the batteries are located in a hot engine room, but are not normally
charged from the
Freedom
charger when the engine is running, do not adjust the tem-
perature to the engine room level. You may need to adjust engine alternator output volt-
age. Remember: Temperatures above 100
0
F are damaging to batteries. Relocate them
or supply forced fresh air ventilation. Charge hot batteries at a lower voltage.
CAUTIONS!
1)Do not adjust to extremes unless the battery is normally at that
temperature. Destructive over or under charging may occur.
2)Multiply values by 2 for 24 Volt systems.
3)Voltages are typical, charger regulation
+ 0.2 Volts DC.
NOTE
At temperatures of 120 degrees F or above , either reported
by the Heart Freedom TC2+2 or if manually set, the Freedom
Charger will go to a high temperature, voltage limited charge
mode to protect the battery.
