Operation
5.2 LED Indicator
There is a bi-color LED indicator on the front of the sense module to indicate
the Battery Monitor’s status. When the Sense Module is
fi
rst powered-up, the
LED blinks red and green while going through a self test. Once the self-test
is complete, use the table below along with the
04 BM: Status
display on the
ME-RC to determine the operating status of the ME-BMK.

1. No power to Sense Module. Check for correct DC
voltage (7 to 70VDC) and correct polarity from pin 3
(-) to pin 4 (+) on the terminal block; or
2. Ensure the terminal block is correctly seated into
the Sense Module.

The Sense Module is transmitting and receiving correctly
with network devices.

BLINKING
Not able to communicate with remote display.
A. If the remote display is off; refer to the remote’s
operation manual for troubleshooting. Ensure inverter
is on and the correct remote communication cable is
connected to the “REMOTE” port on the inverter.
B. If the remote display is on; ensure the remote display
is revision 2.0 or higher. Remote displays with revision
prior to 2.0 are not compatible with the ME-BMK.
Red
ON
The power-up sequence failed.
Unplug the 4-port terminal block from the sense module
and check for correct DC voltage on pins 3 and 4 (must
be between 7 to 70 volts DC depending on the nominal
voltage of the inverter.
Red
BLINKING
No communication or unrecognizable communication
on the network.
1. Check the communication cable; ensure it is con-
nected correctly. If the ME-BMK communication cable
is missing, a standard 2-conductor telephone cable may
be temporarily substituted.
Important: Ensure the RJ11 connector is pushed into the
correct port; you should feel/hear “click” when the con-
nection is made.
