The green receive LED indicates that the EC-BOS-6
AX
is receiving data from a connected device.
These LEDs provide a fixed on-time when data is detected on the port. If these LEDs are on constantly, this
indicates a problem with the communications channel, such as a shorted wire or reversed wiring.

Cleaning
If dust or metal filings are present inside the unit, clean with vacuum or compressed air. Otherwise, no cleaning
inside the unit is required. Optionally, if the cover becomes dirty, you can wipe it with a damp cloth and mild
detergent.
Required Battery Maintenance
Battery life expectancy is a function of its discharge cycles (the number of discharges and their depth) and the
ambient temperature of the battery during normal operation. In most applications, the battery should see
relatively few discharges. Therefore, ambient temperature has more to do with determining the life expectancy
of the battery than does any other factor. If the EC-BOS-6
AX
is installed in a conditioned space, the battery
should provide dependable service for approximately three years (average). In an environment where the
operating temperature is higher (that is, 50ºC or 122ºF), you should only expect the battery to last approximately
one year.
The NiMH battery in the EC-BOS-6
AX
controller is fully discharged when factory shipped. Additionally, NiMH
batteries lose charge over time if not kept trickle-charged (for more details, see “About the Battery,” page 18).
Therefore, even a new unit (or replacement battery) will require up to 18 hours of powered operation before it
can provide reliable backup power (is at full charge).
The EC-BOS-6
AX
monitors the battery and periodically loads the battery to test its ability to maintain
battery-backed functions. Investigate any battery trouble message, and check the battery connections to the unit.
Replace the battery as required. To order a new battery, see the
“Standard Replacement Parts” section on
page 22.
Replacing the Battery
A replacement battery is a complete assembly, that is a battery pack pre-attached to a battery bracket. See
Figure 6 on page 17.
Caution
Use only battery packs approved for use with the EC-BOS-6
AX
.
To replace the battery, proceed as follows:
