Running On Battery Power
When AC power is out the system will alert of an AC power
problem. It will then indicate how many hours are remaining on the
battery. ‘999’ hours is the maximum number displayed. The battery
life monitor calculates the remaining life about four times an hour.
When running on battery power you should closely monitor the
battery life when the hours indicated are ten or below. Battery life
will not be accurate if the battery amp hours are not set correctly
before the power outage began. You can silence this alarm by using
the up, down arrows until the menu silence alarm (24H) appears. To select press ENTER. Once AC power is restored the display
will again display a normal status.
IMPORTANT: When the battery life is calculated at two hours or below, a 'Low Battery' alarm will sound, in addition a
notification will take place if this is the only critical alert. When zero hours are calculated, the pump(s) will no longer operate
to prevent total battery discharge.
Note: If battery life is LOW and battery power is still needed you should connect a replacement battery at this time.
Battery Maintenance:
Check fluid levels, if applicable for each installed battery at least once every six months. To fill fluid levels:
Remove the cell caps of battery. Add distilled water to each cell. If distilled water is not available, tap water with a low mineral
content may be used. NEVER ADD MORE ACID. Fill the battery cell so water is just below the fill cap.
Clean battery posts as needed with a 50/50 solution of water and baking soda or a wire brush. Do not allow any cleaning solution
to enter the battery. Thoroughly dry the terminals and apply petroleum jelly to terminals as needed.
Battery Replacement
The NexPump is constantly monitoring the battery state and will fail
a battery if any one of several tests are not passed within tolerance.
IMPORTANT: Review the safety instructions before proceeding to
replace the battery or batteries.
1. Disconnect each battery, you DO NOT need to power off the
NexPump system unit.
2. Remove each battery and dispose of properly.
3. Connect each new battery. Attach the battery cables to the battery - the BLACK wire to the NEGATIVE (-) post, the RED wire
to the POSITIVE (+) post and tighten securely.
IMPORTANT: Verify the ‘Battery Reverse’ LED is NOT illuminated. If so, reverse connections.
5. Verify battery type and amps under the configuration menu.
6. Turn ON Charger under the configuration menu.
Charger Operation
Charger System Operation:
Charge Rate: 20 Amps
The charging circuit is disabled anytime the battery or electric power
is disconnected or if both pumps are operating. The charge status can
be ‘Full’, ‘Trickle’, ‘Maintain Mode’ and ‘Disabled’. When the
charge is started the display will show ‘Fxx’, where the ‘xx’ is the
actual charge rate in amps. The charge is automatically monitored at
all times. After a full charge is complete the NexPump unit will go
into a trickle charge mode. The display will show ‘Txx’ where the
‘xx’ is the charge rate. When the Trickle mode is complete, the NexPump will go into the ‘Maintain Mode’. In the ‘Maintain
Mode’ charge rates can be very low and may even display ‘M00’ for extended times. It is normal for the 'Maintain Mode’ to run
for multiple days. When the battery is disconnected the charging mode will go into the ‘Disable mode’. The display will show
‘D00’.
