push button for ON | OFF
| MAINTENANCE. The push
button is a multi-function button
that must be held down for
specified durations to complete
each action.
a. Press the push button for
more than two (2) seconds
from OFF |
MAINTENANCE mode to
turn the battery ON.
ON Solid on LED, will dim after 30 seconds
OFF LED off
M
AINTENANCE
Mode LED will light up every 5 seconds.
OFF -> ON
Press and hold the button for >2 seconds until the LED lights up; LED going
from off to fully bright and back to off every 10 seconds; takes ~45 seconds
to turn on.
NOTE
: If the battery detects an external DC voltage at the DC port, the
battery will turn on.
ON -> OFF
Press and hold the button for >10 seconds until the LED turns off after the
quick flash pattern; LED will go from off to on and back to off every 0.9
seconds repeatedly.
ON -> M
AINTENANCE
Press and hold the button for >~2 seconds or two slow flashes of the LED;
You will hear an audible click as the main contactor disconnects.
M
AINTENANCE
-> ON
Must wait for at least 15 seconds after the battery was put into
MAINTENANCE
mode before the battery will accept input. Press the button for
~1 second.
b. Press and hold the push button for 3-5 seconds during
ON mode and this will put the battery to MAINTENANCE
mode. This disconnects the cells and reduces the idle
power consumption of the battery.
c. Press and hold the push button for more than ten (10)
seconds during either ON or M
AINTENANCE
mode and the
battery will turn OFF.
c
Keep the battery ON after successfully mounting and
integrating it into a power system. The system does not need
to be put into storage if a consistent charging source is
available. If there is no charging source available then follow
the directions in the storage section.
NOTE
: The battery will also turn ON from OFF if a DC voltage
is detected at the DC port.
Cold Ambient Temperature
Operation
During cold temperature recharge, if the internal cell
temperature is below 32 °F (0 °C) the Xantrex Battery BMS will
disconnect the cells from the terminals until the internal
temperature has risen above 40 °F (4 °C). This will prevent
damage to the cells.
During cold temperature discharge, if the internal cell
temperature is below –4 °F (–20 °C) then the BMS will
disconnect the cells from the terminals until the internal
temperature has risen above 5 °F (–15 °C). This will prevent
damage to the cells.
If pin 12 is held high, then the battery shall activate its internal
heater when the cell temperature is below 40 °F (4 °C).
NOTE
: If no charge source is available the battery shall
discharge into itself consuming backup time keeping the cells
warm if pin 12 is kept high.
Hot Ambient Temperature
Operation
The Xantrex Battery can operate up to 133 °F (55° C) while
recharging or discharging the battery.
NOTE
: Discharging and recharging the battery will produce a
limited amount of heat inside the battery. Be aware that in high
ambient temperature environments, repeated disconnections
are likely, especially if the battery is under high loads or
recharge current.
Xtend Mode
When the battery's SOC drops to 10%, the Xtend mode
automatically disconnects the battery from the DC Bus. To
reconnect the battery to the DC bus, press the power
pushbutton* for more than 1 sec.
If pin 1 or pin 12 is high when the battery reaches 10% SoC,
then the battery will not disconnect and continue discharging.
NOTE
: If no charge source is available the battery shall
discharge into itself consuming backup time.
The battery can also be manually put into a very low power state
ideal for storage purposes. The battery automatically goes into
OFF
state if any of the conditions are met:
If the battery has been in any fault state without any interaction
for more than 8 hours excluding the following Faults; B: Serial,
C: UT, P: HEAT, and P: IN-H.
NOTE
: A pin 1 or pin 12 high will override the 8 hour timeout and
will not put the battery to
OFF
state until the pack has reached
85% of nominal voltage (10.2V 12V Nominal, 20.4V 24V
Nominal).
* Also, you may press the pushbutton on the Remote.
