USING YOUR
LINK 20
STATUS LIGHTS
These green lights tell you
what units are displayed.
Volts
is the electric
potential to do work
. Voltage is useful to
assess the approximate state-of-charge and to check for proper
charging. Examples: An at-rest, fully charged battery will show
about 12.8 V. A 20-hour rated battery is 100% discharged
when it reaches 10.5 volts with a 20-hour rated load applied.
Typical charging voltages may range from 12.9 to 14.9 volts.
Amps
is the present
flow
of current into (or out of) the battery.
For example, a refrigerator may draw 6 amps of current. This
is displayed as
- 6.0
(6 amps are being
consumed from the
battery
). Discharge is shown as a negative number. Charging
is shown as a positive (unsigned) number.
Amp hours
(Ah) consumed represents the
amount of energy
removed from
the battery. When a 10-amp load is on for one
hour, 10 amp hours are consumed. If you started this discharge
with a full battery, your
Link 20
will show
-I0
in the
display. During charging the
Link 20
compensates for charging
inefficiency and counts back up toward
0.
Time
is an
estimate
of how many hours the battery will sus-
tain a load before it reaches a settable discharge floor. The
estimate may be based on the instantaneous load or averaged.
Four-minute load averaging is the default. During charging
the
Time
display reads
CCC
CCC
CCC
CCC
CCC
, indicating the battery is charg-
ing. When charging, amps is a positive number.
For the
TIME
function to operate correctly, you must correctly enter your battery
capacity, type, and check that an appropriate Peukert Exponent has been selected through
the
SET UP
routines.
