GE General Electric IC695CPE310 IC695ACC400 IC695CBL001A Controller unit
The IC695ACC400 energy pack preserves RX3i CPU user memory during loss of system power and is supplied with the correct interconnect cable.
Key Information
IC695ACC400 is the PACSystems RX3i CPU Energy Pack used with supported CPE302, CPE305 and CPE310 controllers. During a power loss, it powers the CPU long enough to write user-memory contents to non-volatile storage.
The energy pack is used with the correct CPU cable and does not replace the separate real-time-clock battery. System status reference %S0014 reports whether the pack is connected and functioning.
Functions
- Provides temporary energy for an orderly user-memory save when input power fails.
- Supports battery-less retention of CPU user memory on the compatible RX3i CPE platform.
- Reports connected/failed status through the controller system reference.
- Allows the CPU to complete its non-volatile write before the stored energy is exhausted.
Specifications
| Manufacturer | Emerson / GE Intelligent Platforms |
|---|---|
| Model | IC695ACC400 |
| Product Family | PACSystems RX3i |
| Product Role | CPU Energy Pack |
| Supported CPU Family | RX3i CPE302, CPE305 and CPE310 platforms documented for the energy pack |
| Memory Function | Supplies shutdown energy so the CPU can write user memory to non-volatile storage |
| Status Reference | %S0014 PLC_BAT: 0 connected/functioning; 1 not connected or failed |
| Initial Charge Behavior | A fully discharged pack may require several seconds to reach operating level |
| CPU Indication During Charge | CPU STATUS LED blinks green while the pack charges to operating level |
| Time-of-Day Clock | Maintained by the separate RTC battery, not by the energy pack |
| Companion Cable | Use the approved RX3i energy-pack cable for the installed CPU |
| Documentation | PACSystems RX3i Energy Pack IPI GFK-2724 |
Installation
- Mount the pack and route the approved cable without strain or sharp bends.
- Connect it only to a supported RX3i CPU with system power safely removed.
- Allow a depleted pack to charge before interpreting the CPU STATUS indication as a fault.
- Verify %S0014 and perform a controlled power-loss memory-retention test before returning the controller to service.
Lifecycle
- Inspect the cable, connector latch and enclosure during scheduled controller maintenance.
- Record energy-pack alarms and replacement date with the CPU asset history.
- Keep the RTC battery maintenance plan separate because the two devices protect different data.
FAQ
Which CPU information should accompany an IC695ACC400 order?
Provide the exact CPE302/CPE305/CPE310 catalog number, hardware suffix, firmware, installed cable number and a photograph of the energy-pack connector.
Why can a newly installed IC695ACC400 make the CPU STATUS LED blink?
A fully discharged pack needs time to charge to its operating level; wait for the documented charge behavior and then verify the system status reference before diagnosing failure.
Does IC695ACC400 preserve the RX3i time-of-day clock?
No. User-memory retention and the real-time clock use different mechanisms, so the RTC battery still needs its own maintenance schedule.
How should IC695ACC400 be acceptance-tested after replacement?
With a verified project backup, confirm %S0014, allow full charging, perform a controlled power interruption and verify the CPU restores the intended user memory and operating state.
What supply-scope detail prevents an IC695ACC400 mismatch?
State whether the quotation must include the energy pack, the correct CPU interconnect cable and any mounting hardware; do not assume a loose pack includes those items.
