When the battery pack voltage hits the peak limit the yellow LIMITS LED will come on along with the flashing
blue TIMER LED and the charger will cut back.
NOTE: If the battery pack is not heated for any reason such as outdoors in a cold climate, the peak charging
voltage threshold will likely need to be raised in order to assure a complete charge. This is especially true for
lead acid batteries. Many users turn the volts trim to the absolute maximum safe level for the batteries during
the winter and then back down to normal during the summer months. Always consult your battery manufacturer
for information on the peak “fully charged” voltage specifications and how they change based on temperature.
Use caution on the first charge cycle and make sure to check that the point at which the charger volts trim limit
is reached is really the correct voltage for your specific batteries.
“REG BUS”
This is the 6 pin RJ jack where the BMS communication line plugs into the charger.
This port allows the individual battery regulators to communicate with the charger.
For more information on the specific reg bus pins refer to the “Reg Bus Wiring”
section later in this manual.
NOTICE! If your vehicle is equipped with a Manzanita Micro Battery Management
System, ensure that the reg bus data cable is fully plugged into the charger
whenever the vehicle is charging. The communication data cables are hooked to the
regulators in a daisy chain fashion. Make sure that each of the smaller data cables
are all plugged in where they should be before charging. If there is an unplugged
portion of the reg bus, the charger cannot communicate with the regs and this
could cause overcharging and potential fire! The RJ connectors are similar to
phone cord connectors and they are designed to snap into place and stay
connected. If a cable is disconnected insure that it is fully reconnected. An audible
*click* should be heard when the RJ plug is fully inserted and it should not be able to
be pulled out without first pinching the small plastic tab underneath the plug. For
more information on reg bus cables refer to the “Reg Bus Wiring” section later in this
manual.
“POWER
” - Green LED
The bright green POWER LED indicates when the charger is on. Input power is
being supplied to the unit and the main breaker is in the ON position.
“WARN
” - Red LED
The red WARN LED should blink briefly when the charger is first powered up and
then remain off for the duration of the charge. If this indicator stays on, turn down
the AMPS knob immediately, turn off the charger’s breaker switch and consult
Manzanita Micro or a qualified service technician. This LED could indicate an over
voltage or over temperature condition. It could also be indicative of an open circuit
condition in the pack. Turn down the AMPS knob and check to make sure there is
no open circuit condition in the battery pack. Check the gray SB-50 Anderson
connector to insure that it is tightly connected and look for other disconnected
battery cables. If the charger will not work and the circuit is complete, contact
Manzanita Micro.
NOTICE!
DO NOT let the charger try to put current into the battery pack if there is
an open circuit condition anywhere in the circuit. Never unplug the gray SB-50
