“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 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 lead to a
potentially damaging situation if there is an un-matched battery cell in the
pack! 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 DC power connection
(Battery Pack side) to ensure 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 in the circuit. Never unplug the DC (battery pack side)
Anderson connectors from your charger while it is charging! If the battery pack is
disconnected while the charger is putting out power the charger can be damaged.
Failure to heed these warnings may result in significant internal damage to the
charger which is not covered under your warranty!
