Using a BMK: Setup
8.0 Using a BMK
This section discusses how to set up, operate and troubleshoot the BMK using the ME-RTR router. Refer
to the mini-index below to direct you to the appropriate section.

8.1 ME-BMK Setup (with the ME-RTR)
The BMK SETUP menus can be accessed from the BMK Home screen or the System Home screen
(see Figure 8-4). Two settings are available in the BMK, the fi rst sets the battery effi ciency (05A
Charge Effi ciency) and the second sets the capacity of the battery bank (05B Battery AmpHrs Size).
Info: To access the BMK Home screen, fi rst press and hold the METER button (~3
seconds) to display the System Home screen. From the System Home screen, press
the PORT button, or rotate the SELECT knob to the port# where the BMK is connected.
• SETUP: 05A Charge Effi ciency – The Charge Effi ciency setting allows the battery monitor to
calculate the battery’s charge effi ciency. The charge effi ciency can be calculated automatically
using the Auto setting, or can be calculated based on a fi xed effi ciency value determined by
the user (see Figure 8-1).
Default setting: Auto
Range: Auto, 50-99%

Adjusting the Charge Effi ciency Setting
The battery monitor is shipped with the charge effi ciency set to Auto. This allows the battery
monitor to automatically calculate variables that affect the charging effi ciency such as battery
type, battery age, and how the batteries are maintained—which is not always constant. With the
Auto setting, the effi ciency is recalculated each time the batteries reach a 100% state of charge.
This setting can also be manually adjusted from 50% to 99% if the battery’s charge effi ciency is
known. When using a setting other than the Auto setting, the battery monitor uses the manual
setting to calculate the AH I/O display. For example, if you set the charge effi ciency to 90% and
100 AHrs are removed from the battery, the AH Net display would read 000 only after 111 AHrs
have been returned to the battery. However, if the charge effi ciency is manually set and inaccurate,
the SOC information will be more inaccurate with every charge. Thus, continually monitor the AH
I/O reading (along with the SOC display) under the router’s METER button.
To access the AH I/O reading: From the BMK Home screen, press the METER button. The 05A
BMK SOC display appears. Turn the SELECT knob until the 05D Amps Hours In/Out menu appears.
After several charge and discharge cycles (below 80% SOC), the AH I/O reading should be slightly
positive when the SOC display reads 99%.
To view the SOC display: From the BMK Home screen, press the METER button. The 05A BMK SOC
menu appears. If the AH I/O reading is below 000 (negative number) when the SOC display reads
99%, then increase the charge effi ciency setting. If you fi nd that the AH I/O reading is substantially
above zero when the SOC display reads 99%, then decrease the charge effi ciency setting.
