caution to be sure that the positive and negative terminals are on the same jar. Tighten the terminal bolt to the jar
manufacturer’s recommended torque setting (typically 100-120 inch/oz). At this point, the green LED on the sensor will
flash at about a one second rate. If the LED is not flashing confirm that the sensor is connected with the correct polarity.
NOTE:
NOTE: The sensors can be connected to the daisy chain in any order. Choose an order that is
aesthetically pleasing and minimizes the cable clutter.
Be sure that you have read the general sensor installation section above before proceeding. Every High Voltage sensor
module has a unique factory-programmed address built into it. At installation and system initialization time, the site
controller ‘discovers’ each sensor module’s factory address and assigns the sensor to a jar. The specific jar that the sensor
gets assigned to depends on the order in which the sensors were discovered, but the user can change the assignments from
the Site Controller web page after the installation is complete. Refer to the Site Controller Manual to see how this is done.
If the jars are in a cabinet start with a top shelf and work down, one shelf at a time. In most cases it will be necessary to
remove the jars from the UPS cabinet to gain access to the Jar terminals. As each jar is reinstalled connect a sensor to each
jar, as described above in the general installation
instructions. Pay particular attention to the sensor LED,
tightening torque, and be sure to record the sensor
address and jar number since it may require removing
several jars to correct a problem. The LED should be
flashing green when the jar is reinstalled.
As the sensors are installed record the jar number and
address of each sensor. The jars can be numbered in any
order. This information will be required later to put the
batteries in the proper order on the Web page.

Sensor LED
Once the sensor is installed successfully on the jar the green LED on the sensor will begin to blink periodically (roughly once
per second). When the interconnection daisy-chain containing the sensor string is connected to the site controller, the auto
discovery process will begin. As each sensor is discovered by the site controller, its LED will stop the 1 second green
flashing, flash red momentarily, and will illuminate solid green. Shortly after the sensor is discovered and its LED changes to
solid on green, the sensor will make an admittance measurement. During this measurement the LED will be switched off
until the measurement is complete. (Early sensors flashed the green LED very rapidly during the measurement).
After this initialization sequence, the sensor’s LED will stay on green until it is polled by the Site Controller. Upon receiving
a poll the sensor LED flashes off briefly and then comes on solid green.
The sensor LED will flash red if the sensor is reporting an alarm as defined by the Site Controller configuration.
The sensor LED will flash alternately red and green if the sensor flash function is activated from the Site Controller Web
page.
The state of the LED can also be controlled through SNMP by the SNMP Manager.
