04A BMK Status – This menu selection offers read only displays that give the

current operating status of the battery monitor. This selection also provides

information to determine if there is a power-up fault condition.

BM: Pwr-up Fault – The battery monitor faulted when it was powered-

up. The fault occurred because the power-up self-test failed. See the

Troubleshooting section.
BM: No Comm – The battery monitor is not communicating with the

remote. This typically means a ME-BMK is not installed in the system.

If installed, view the Sense Module LED and use Table 6-1 to help de-

termine the issue.
BM: Ready – The battery monitor is connected and actively monitoring

the battery system.

04B SOC – This display is the best way to monitor the actual state of the

battery. The read only display shows the State Of Charge (SOC) for the con-

nected battery bank. The SOC represents the condition of the battery as a

percentage of the available capacity left in the battery. The range is 0% to

100%, where 100% represents a fully charged battery and 0% means the

battery is completely discharged.
When the Sense Module is fi rst connected, the batteries will need to be fully

charged (i.e., SOC = 100%) at least once to establish a SOC reference point.

While this reference point is being calculated, the display will show “Think’n”,

to indicate that the SOC reference point is being calculated. After the batter-

ies are fully charged, the display will change from “Think’n” to “100%” and

begin to provide accurate SOC percentage values.
If the Sense Module is disconnected from power, this display resets to “Think’n”

and the batteries will require another full charge before this display begins

providing SOC percentage information.

Info: Try to limit battery discharging to 50% of capacity (keep

battery above 50% SOC). If batteries are allowed to be continually

discharged below 50% SOC, their effective service life will be con-

siderably shorter. This 50% rule has been determined to be the best

compromise between available energy and the maximum number of

discharge cycles a battery can provide.
