Battery Maintenance; Battery Disposal - Honeywell WEB-600E Manual

CAUTION
Use only NiMH battery packs approved for use
with the WEB-600E.
Installing/replacing a NiHM batter assembly on a WEB-600E:
1. If replacing an existing battery in a controller not cur-
rently configured for SRAM usage, backup the control-
ler's configuration to your PC using the appropriate
WEBs-AX software tool (for example, Workbench).
2. If a station is running, stop it using the platform Applica-
tion Director view.
3. Remove all power from the controller. Wait for all LED
activity to stop (if a battery is already installed, this may
take a minute or two).
4. Remove the cover. See "Removing and Replacing the
Cover" on page 5.
Note the Option Slot area where the NiMH battery
assembly mounts.
5. If a battery assembly is already mounted, unplug the
battery from the connector on the controller board (see
Fig. 9).
6. Remove the four screws that secure both option slot
end plates (and if installed, the existing battery assem-
bly bracket). Set the screws aside.
7. Remove any existing battery assembly (if applicable).
8. Plug the battery connector plug of the new battery
assembly into the battery connector on the controller
(see Fig. 9).
9. Set the new NiMH battery assembly on top of the option
card slots, over the option card end plates. Ensure the
bracket mounting holes are aligned with the standoffs.
10. Place the four screws through the battery bracket,
option card end plates, and into the standoffs on the
controller's base board. Using a screwdriver, hand
tighten these screws.
11. Replace the cover.
12. Restore power to the controller and verify normal opera-
tion.

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 NiMH battery should see relatively few
discharges. Therefore, ambient temperature has more to do
with the life expectancy of the battery than does any other
factor. If the controller is installed in a conditioned space, this
battery should provide dependable service for approximately
three years (average). In an environment where the operating
temperature reaches the highest range (50ºC or 122ºF), you
should only expect the battery to last around one year.
A new NiMH battery is typically only partially charged when
shipped. Additionally, NiMH batteries lose charge over time if
not kept trickle-charged (for more details, see "NiMH battery
pack" on page 13). Therefore, even a new or replacement
battery will require up to 18 hours of powered operation before
it can provide reliable backup power (is at full charge).
The controller monitors the NiMH 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 "Standard Replacement
Parts" on page 16.

Battery disposal

Please dispose of the used NiMH battery in accordance with
local, state, and federal regulations.
WARNING
Do not incinerate or mutilate the battery, as this
may cause it to burst or release toxic materials.
If regulations specify returning the old battery to a recycling
center, but no acceptable recycling center can be found,
please return the old NiMH battery pack to Tridium for proper
disposal.
