A The “REFRESH DISPLAY” momentary button can be pressed and held to update the display
during normal operation.
During normal operation, the display is updated automatically at
intervals of three (3) minutes. The REFRESH DISPLAY button must be pushed and held until
the home page is completely repopulated. If the button is released too soon, the display will
not populate. If this happens, wait five (5) seconds, press and hold button until home page is
repopulated.
B A timestamp for the last “refresh” is updated and displayed, whether it occurred automatically or
by pushing the refresh button.
C The SOC is reported visually by a five-segment “fuel gauge”. Each segment represents 20%
increments up to 100%. Each segment fills completely when the SOC reaches the lowest
percentage for that segment. For example, the segment on the right will fill completely when the
SOC reaches 81%.
D If the ESM 2000 is connected to a battery bank, the voltage reported ( D ) is bus voltage.
If the battery is not connected to any other equipment, the value reported here is battery voltage.
Nominal voltage = 26.4 VDC; voltage @ 100% SOC ≈ 30.4 VDC; voltage @ 0% SOC ≈ 20.0 VDC.
E The current (Amps) value is positive when the ESM is charging and negative when the ESM is
discharging.
F If/when a battery fault occurs, the word “FAULT” appears in the upper right corner of the display.
If the fault is unattended for three (3) minutes, “FAULT” appears in large font, filling the screen
(Figure 17). If the fault is not corrected within 60 minutes, the ESM will enter storage mode even
with the POWER switch in the ON position.
Additional information about the fault can be found on the second “page” (Diagnostic Screen) of the
Battery Status Indicator, accessed by pressing the Refresh Display button twice.
