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 first 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.
Table 5-1, LED Indicator Guide
LED
Status
Meaning
OFF
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.
Red ON, Green
ON, Red On,
Green ON
Power-up sequence (1 second interval between each
color). The Sense module is performing a self-test
and occurs when first connected to power.
Green
ON
Normal operation
The Sense Module is transmitting and receiving correctly
with network devices.
Green
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.
