Using a BMK: Monitoring
8.2.4 BMK Remote Status Messages
A BMK status message may be an operational or fault message. Access the METER: 05A BMK Sta-
tus menu to view the BMK’s current operating status. The status is important when determining
if the BMK is working correctly, or for troubleshooting a BMK installation.
8.2.4.1 BMK Remote Operational and Fault Statuses
Refer to Table 8-1 for a brief description of the BMK operational and fault statuses that may dis-
play on your remote. Refer to Section 8.3.2 “Resolving BMK Faults using the ME-ARC” for help in
diagnosing and resolving BMK fault conditions.
Table 8-1, BMK Remote Operational and Fault Statuses
Status Description
BMK Ready Indicates the BMK is correctly communicating with the inverter/charger.
No Comm The BMK is not communicating with the inverter/remote. This is a nor-
mal status if there is no BMK connected in the system.
BMK not present If a BMK is installed, view the BMK sense module’s LED.
a) If the LED is green, disconnect the terminal block for 5 seconds, and
then reconnect it to ensure the terminal block is correctly seated into
the sense module.
b) If the LED is blinking red, there is no communication or there is an
unrecognizable communication on the network. Check the communi-
cation cable—ensure it is connected correctly. If the ME-BMK commu-
nication cable is missing, a standard 2-conductor telephone cable may
be temporarily substituted.
Factory Fault The BMK has lost its factory-set internal calibration reference.
Power-up Fault A fault occurred during the BMK’s power-up sequence.
Unknown Fault ## A fault code that is not recognized by the remote.
8.2.4.2 BMK Remote SOC Statuses
The following “SOC” statuses indicate the battery’s current state of charge. Access the METER:
05B Battery SOC menu to view the BMK’s current SOC status.
Note: If a fault condition (i.e., Factory, Power-up, or Unknown fault) is present and appears on
the 05A BMK Status display, it will also appear on the 05B Battery SOC display as well until it has
been resolved.
Table 8-2, BMK Remote SOC Statuses
Status Description
Think’n When the BMK sense module is first connected, the batteries need to
be fully charged (i.e., SOC = 100%) to establish a SOC reference point.
The BMK sense module is disconnected from power and the batteries
require a full charge before the remote display begins providing SOC
percentage information.
###% The batteries are fully charged, the display has changed from “Think’n”
to “100%” and is ready to provide accurate SOC percentage values.
Factory Fault
The BMK has lost its factory-set internal calibration reference.
Power-up Fault
A fault occurred during the BMK’s power-up sequence.
Unknown Fault ## A fault code that is not recognized by the remote.
No Comm Refer to Table 8-1 above.
