Introduction 1
Section 1: Introduction
Many PACSystems CPUs require a battery, an energy pack or a supercapacitor array 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 RSTi-EP,
RX3i and RX7i CPUs, and RXi Controllers. Other manuals and documents published by
Emerson may 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.
•A list of CPUs which rely on supercapacitor technology.

Section 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; no other battery has a better memory retention time. It is compatible with all
PACSystems CPUs requiring a battery for memory retention. 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 and 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 external mounting is required
due to battery and charger size, no support for low battery detection, limited temperature
range (0 to 50°C, 32 to 122 °F), and inability to charge in a hazardous location.

Note:
•Due to the higher capacity of auxiliary and smart auxiliary battery packs, the estimated life of
these battery packs approaches their shelf life (7years) in applications where the CPU is never
powered down.
•Unscheduled power outages and temperature changes will reduce the number of days and
should be considered when calculating the duration of the battery life.

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
shutdowns should not exceed 15 days as the battery voltage may drop to 0 V, resulting in
the loss of CPU RAM memory contents.
Figure 1: Low Battery Countdown Example
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.

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.

Nominal Battery Life
The nominal battery life at 50ºC (122 ºF) 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, 77 ºF). 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 (77 ºF) and will help improve battery life. Do not operate the battery at less
than 0ºC (32 ºF) or greater than 50ºC (122 ºF).
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 (68 ºF) chart will no longer be valid.
Battery Mounting
With power removed from the equipment, drill four #29 (0.136”) (3.45mm) holes in the
panel mounting surface, and tap for #8-32 threads, according to the hole pattern shown in

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 blinking 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.

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.
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
