BATTERY CONNECTED IMPROPERLY:
If the battery cables are connected to the wrong posts, the
‘Reversed Polarity’ Red LED will illuminate. If the NexPump
unit is on when the reverse connection is made, an alarm
will also sound and the input power will indicate as off as well
as a FAN error.
Correct by reversing the battery cables.
RUNNING ON BATTERY POWER:
A ‘XXH’ indicates the NexPump is on battery power. ‘99H’ will be
the maximum number displayed as shown above and does not
reflect the actual battery life as this may be much greater. The
number displayed is the approximate time remaining until
the battery is discharged enough that the pumps will no
longer function normally. The Battery Life Monitor calculates
the remaining life approximately 4 times an hour. A close
approximation should be displayed within the first 30 - 45
minutes. When running on battery power you should
closely monitor the Battery Life. Especially at 2 Hours
left, at high duty cycle times the battery can quickly go
to 0 Hours. This can take less than 1 hour, so be aware.
While every attempt to accurately calculate the remain-
ing battery life, fluctuating pump(s) times, battery condi-
tion and battery state before going to battery power will
affect the calculated time throughout the power loss. An
alarm will also sound from the loss of electric power, which
may silenced (See Silencing the Alarm). Once AC power is
restored the display will again display the charge status. A charge
cycle may also be enabled at this time.
IMPORTANT: When the Battery Life is calculated to be 2 Hours,
an alarm will sound to let you know it is low on Battery Power.
When the NexPump calculates there are zero hours left on the
time remaining, the pump(s) will no longer operate. The
pump(s) are disabled to prevent the battery from completely dis-
charging and turning off the NexPump unit. When zero battery
life is remaining the NexPump unit can still operate for hours to
notify there are problems.
Auto Notification Module Installed:
Notification will occur on the initial loss of electric power. If
you silence the alarm before the notification occurs, notifica-
tion is canceled. When the calculated battery life is two
hours, notification will occur with the impending battery life.
Note: If Battery Life is low and Battery Power is still
needed you may connect a spare Battery at this time.
If the NexPump is powered up with only the battery and is
on battery power when the initial self test is scheduled, the
self test WILL NOT run.
