Introduction
GFK-2741C March 2015 1
1. Introduction
Many PACSystems CPUs require a battery or energy pack to back up volatile memory. This memory is separate
from the non-volatile flash memory. This manual covers the technologies used to back up volatile memory on
PACSystems RX3i and RX7i CPUs, and RXi Controllers. Other GE Intelligent Platforms manuals and documents
discuss memory retention technologies in passing. However, when it comes to energy sources used by PACSystems
to back up volatile memory, this manual should be considered the definitive source.
Other methods of retaining volatile memory, such as real-time clock batteries, are not covered by this manual.
Note, however, that RX7i CPUs use the same battery mechanism to back up the calendar clock and user memory.
This manual includes:
A battery selection guide, information on battery life and usage, disposal instructions, and agency
compliance
RXi Energy Pack specifications, installation, operation, and service and maintenance

2. Batteries
2.1 Battery Selection
2.1.1 Conventional Coin-Cell Lithium Battery (IC698ACC701A, IC698ACC701B)
The conventional coin-cell lithium batteries are relatively small and have the advantage of fitting inside the battery
compartment of compatible CPUs. The disadvantages are limited memory retention time, limited CPU compatibility,
and no support for low battery detection.
2.1.2 Conventional Auxiliary Battery (IC693ACC302)
The conventional auxiliary battery should be used where maximum memory retention time is desired. It is
compatible with all PACSystems CPUs requiring a battery for memory retention and no other battery has a better
memory retention time. The disadvantages are that external mounting is required due to battery size and it does
not support low battery detection.
2.1.3 Smart Coin-Cell Lithium Battery (IC698ACC701, revision C & later)
The smart coin-cell lithium battery is an improvement on the conventional coin-cell lithium battery and adds
reliable low battery detection for compatible CPUs at the expense of reduced memory retention time. The improved
battery is slightly larger, but is still able to fit into the battery compartment of compatible CPUs. The disadvantages
are reduced memory retention time as compared to conventional batteries and limited CPU compatibility. For CPUs
that do not support low battery detection, the conventional coin-cell lithium battery may be a better choice as it will
provide longer retention time.
2.1.4 Smart Auxiliary Lithium Battery (IC695ACC302)
The smart auxiliary lithium battery is an improvement on the conventional auxiliary lithium battery and adds
reliable low battery detection for compatible CPUs at the expense of a slight reduction in memory retention time.
The disadvantage is that external mounting is required due to battery size. For CPUs that do not support low
battery detection, the conventional auxiliary lithium battery may be a better choice as it will provide longer
retention time.
2.1.5 Rechargeable Battery (IC690RBT001)
The rechargeable battery is designed for customer applications that use memory retention on a cyclical basis.
Customers who shut down equipment and rely on battery backed memory on a daily or weekly basis should
consider the use of this battery. It is compatible with all PACSystems CPUs requiring a battery for memory retention
and is slightly larger than the auxiliary lithium batteries. The disadvantages are that external mounting is required
due to battery and charger size, no support for low battery detection, limited temperature range (0°C –50°C), and
inability to charge in a hazardous location.

2.3 CPU Support of Low Battery Detection
For low battery detection to work reliably, a smart battery (IC695ACC302 and IC698ACC701 revision C or later) must
be used with a CPU that supports low battery detection, such as the following:
IC695CPU3104all hardware and firmware versions
IC695CPU315 all hardware and firmware versions
IC695CPU320-Fx and later hardware revisions with firmware revision 6.02 or later
IC695CRU320-Cx and later hardware revisions with firmware revision 6.02 or later
IC698CPE0104all hardware and firmware versions
IC698CPE0204all hardware and firmware versions
IC698CRE0204all hardware and firmware versions
IC698CPE030-Jx and later hardware revisions with firmware revision 6.75 or later
IC698CPE040-Jx and later hardware revisions with firmware revision 6.75 or later
IC698CRE030-Hx and later hardware revisions with firmware revision 6.75 or later
IC698CRE040-Hx and later hardware revisions with firmware revision 6.75 or later
The use of a non-smart battery or a CPU not on the above list will result in the low battery detection bits being
unreliable.
Low/failed battery conditions are indicated by CPU LED operation and %S status bits. For details, refer to
Diagnostics in the PACSystems CPU Reference Manual, GFK-2222.

2.4 Smart Batteries
2.4.1 Smart Battery Operation
The battery output voltage is > 2.5 V when the battery is operating in its good state. At the end of the battery good
period, the battery output drops to <2.5 V for the battery low state. The period for the battery low state is 15 days
for all CPU models. Once battery output voltage drops to <2.5V, compatible PACSystems CPUs detect this as a
battery low condition; a Low Battery fault is logged in the Controller fault table and the red Battery LED on the CPU
starts blinking.
Once the low battery state is active, the user has 15 days of accumulative battery backed energy left for CPU RAM
retention during power loss. Since the low battery period may start while the PLC is powered down and faults
cannot be logged in this state, the low battery fault date is unlikely to indicate the starting point of the 15 day count
down. System power downs should not exceed 15 days as the battery voltage may drop to 0V, resulting in the loss
of CPU RAM memory contents.
Consider the following example:
Battery Good
Battery Low
Controller Power Down
Controller Power Up
T1
T2
Battery Low period starts
Battery Low fault logged
Time
Controller
State
15 days
T3

2.5V

The Battery Low period of 15 days starts at Point T1, but the low battery fault is logged at Point T2, when the
controller is powered ON. The user should be aware that the Low Battery fault timestamp does not indicate the
start of the 15 day Battery Low period.

2.4.2 IC695ACC302
The IC695ACC302 Auxiliary Smart Battery Module is an enhanced version of IC693ACC302. In addition to providing
an extended backup time for volatile memory on PACSystems CPUs compared to the standard memory backup
battery (IC698ACC701), the smart battery module has a battery monitoring circuit that enables the user to detect
the low battery state before it is completely drained. Once an IC695ACC302 Auxiliary Smart Battery Module is
connected to a CPU model, it must be used with only that specific CPU model for the remainder of its life to insure
proper Low Battery indication. IC695ACC302 Auxiliary Smart Battery Modules should be replaced every 2 years or
once a Low Battery fault is logged in the CPU, whichever occurs first.

2.5.1.2 Nominal Battery Life
The nominal battery life at 50ºC is 12 months or 60 charge/discharge cycles. Battery life is negatively affected by
higher temperatures, and can be significantly improved by operating closer to room temperature (25ºC). When
deciding where to mount the battery, consider how the mounting location will affect the battery temperature. For
most industrial installations, mounting the battery below the PLC rack will result in a temperature closer to 25ºC
and will help improve battery life. Do not operate the battery at less than 0ºC or greater than 50ºC.
The battery will continue to operate after 12 months or 60 charge/discharge cycles, however the battery capacity
will decline and the times listed in the Battery Compatibility and Memory Retention Time in Days at 20°C chart will no
longer be valid.
2.5.1.3 Battery Mounting
With power removed from the equipment, drill four #29 (0.136”) holes in the panel mounting surface, and tap for
#8-32 threads, according to the hole pattern shown in the following figure. Use care to keep metal chips from

2.5.2.2 Operation
Charging begins when a battery pack is connected to the charger. The LED is initially orange, and changes to red
when the fast charge starts. When the cells are fully charged, the charger goes into top-off charge mode before
switching to trickle charge mode. During the top-off charge, the LED is green with short, intermittent orange
flashes. When the top-off charge is complete, the charger goes into trickle charge mode, and the LED color
changes to green.
If the charger detects a fault, the charger will stop the fast charge current and switch to trickle charge mode. The
LED will then indicate error by flickering green and red. The fault condition can be caused by the battery pack,
wiring, or the charger.
If input power is turned off, the charger will reset. The charger starts a new charge cycle when the power is turned
back on.

2.6.2.3 CPU Battery Low Indication
The IC693ACC302 Auxiliary Battery module will not reliably provide the CPU with a battery low indication. User logic
should not rely on any of the battery status bits when using this battery.
2.6.2.4 Diagnostics
This unit is not user-serviceable. The unit has a built-in 1-Amp fuse that will open if the unit is subjected to a short
circuit or severe overload condition. This fuse is sealed inside the battery pack and is not replaceable.
To test the unit if you suspect that the fuse has opened, turn off PLC power, unplug the battery unit, and carefully
check the battery cable connector pins for presence of voltage with a volt meter. If voltage is present, the fuse is
not open. If no voltage is present, the internal fuse has probably opened and the unit will have to be replaced. Only
perform this check in a non-hazardous environment.

2.7 Battery Installation Instructions
Warning
Explosion Hazard - Do not add, remove, replace or recharge a battery unless the area is
known to be non-hazardous.
2.7.1 Installation in Hazardous Areas
1. Install the CPU in a system that is located outside the hazardous area.
2. Apply power to the system and install the battery.
3. Power the system down.
4. With the battery still attached, remove the CPU and install it in the system that is located in the hazardous area.
2.7.2 Preparation and Mounting
If installing an auxiliary battery (IC693ACC302 or IC695ACC302), securely mount the battery to the panel
mounting surface before attempting to connect the battery to the CPU. For mounting instructions, see the
previous sections.
If using a Smart Battery (IC698ACC701C or later, or IC695ACC302), connect the Enabling Cable to the Battery
using the 4 pin connectors.
Note: Disconnect the enabling adapter cable from the battery pack when the battery is not attached to a CPU
(when the enabling adapter cable is connected, the battery drains to support the smart circuitry, even if
it is not attached to the CPU).
If using the rechargeable battery (IC690RBT001), securely mount the battery and its charger (IC690CRG001) to
the panel mounting surface before attempting to connect the battery to the CPU. For mounting instructions,
see the previous sections. Insert the charging jack into the threaded connector on the side of the battery and
hand-tighten the screw lock to secure it.
2.7.3 Installation and Replacement
1. Access the battery compartment on the CPU by opening the door (RX3i) or removing the battery cover (RX7i) -
(refer to the battery installation figures below)
2. Turn on power and wait for the CPU to complete its initialization. Initialization is complete when the OK LED on
the CPU remains on.
3. Connect the battery to either of the battery connectors on the CPU. If replacing an existing battery, connect the
new battery to the other connector before disconnecting the old battery (be careful to not disconnect the old
battery until the new battery is connected). Properly discard the old battery per the disposal instructions (See
Safe Handling & Disposal).
4. For Coin Cell batteries, secure the battery in the compartment and close the compartment door (RX3i) or install
the battery cover (RX7i).
5. For auxiliary batteries and the rechargeable battery, route the battery cable through the notch in the base of
the battery compartment (RX3i) or the slot in the bottom of the battery cover (RX7i) and close the compartment
door (RX3i) or install the battery cover (RX7i).
Be careful not to pinch the battery cable when closing the battery compartment cover.
