Operation

CHARGER OPERATION

The backup pump will activate automatically when the
backup sump water level rises far enough to trip the float
switch.
If the power to the charger circuit is interrupted, the
length of time that the backup pump will run depends on
the Ampere-hour capacity of the battery used, the battery
charge level, and the required vertical pumping distance.
Extended periods of operation (for example, during an
extended power outage) may exhaust the battery. The
battery charger will begin charging the battery as long as
the battery has a voltage differential of 3 Volts or more.
Recharge Time:
MBSP: Approximately 100+ hours to fully recharge a
27M battery in a "dead battery
condition". The approximate recharge time for the 24M
battery is 75 hours.
MBSP-PLUS-18T: Approximately 19 hours to fully
recharge a 27M battery in a "dead battery condition".
The approximate recharge time for a 24M battery is
15 hours. Industrial standards define a "dead battery
condition" as 9 Volts or less.
The 5 Stages of the Charging Process for
Model MBSP:
NOTICE: The LED's will only illuminate once the AC
power has been applied. They will not light up if the
charger is not plugged in.
1. Yellow LED light flashing on and off indicates:
Prequalification test stage is in progress. Normal
duration of this stage ranges from 18 minutes to 27
hours. If a battery has been left in a state of discharge
for long periods this stage may require 27 hours to
determine if the battery will even accept a charge.
2. Yellow LED light continuously on indicates:
Constant current charge stage. Charger is charging
battery at the full rated output. This stage ends when
the battery terminal voltage reaches the factory preset
voltage level.

3. Yellow LED light continuously on also indicates:
Constant voltage charge stage. Battery cells are being
equalized.
4. Green LED light on indicates:
Float charge stage. Battery is charged and ready
for use. Charging has stopped. To maintain a full
charge on the battery, the yellow and green LED may
alternately turn back on. This means the charger is
briefly turning back on to keep the battery voltage
from falling below a preset voltage level.
5. Recycle charge stage:
The charger automatically initiates a charge cycle that
begins with the prequalification test stage. This occurs
once the battery has been in the float charge stage for
84 days.
The 5 Stages of the Charging Process for
Model MBSP-PLUS-18T:
NOTICE: The LED's will only illuminate once the AC
power has been applied. They will not light up if the
charger is not plugged in.
1. Yellow "charging"(bicolor) LED flashing slowly
indicates:
A. Prequalification test stage is in progress. The normal
duration of this stage is 20 seconds to 3 minutes.
However, if a battery has been left in a state of
discharge for long periods or if the initial voltage is
less than 10.5 volts, this stage may require 5 hours
to determine if the battery will even accept a charge.
2. Yellow (bicolor)"charging" LED continuously on
indicates:
Constant current charge stage. Charger is charging
battery at full rated output.
3. Yellow (bicolor)"charging" LED flashing quickly
indicates:
Constant voltage charge stage. Battery cells are being
equalized. This could last up to 14.5 hours.
4. Green (bicolor) "charging" LED indicates:
Float charge stage. Battery terminal voltage is reduced
to a regulated voltage and battery is being maintained
at full charge.
