IC697ACC701 GE Fanuc Series 90-70 Lithium Battery Assembly

The GE Fanuc IC697ACC701, also cataloged as the IC697ACC701 Lithium Battery Assembly, operates as a dedicated hardware component for volatile memory data preservation within Series 90-70 PLC platforms. Configured to supply continuous backup voltage to the central processing unit and programmable coprocessor modules, this unit maintains the structural integrity of the application program registers, system configuration files, and internal hardware clocks during primary power source interruptions.

Hardware Specifications

Firmware Flash Compatibility and Dynamic Register Memory Protection

The component interfaces with the host processing board via low-resistance power rails to protect static random-access memory (SRAM) registers from dropouts. Firmware flash compatibility protocols across the Series 90-70 architecture rely on this battery link to store runtime variables before permanent flash memory commit cycles execute. The internal circuitry of the attached CPU monitors the cell discharge curve through the backplane bus infrastructure, triggering a hardware system fault register bit when the cell terminal potential drops below predefined operating limits.

Frequently Asked Questions

Q: What is the estimated service life of this battery assembly under typical operating conditions?

A: The operational life span typically ranges from 1 to 2 years under continuous unpowered backplane states. When the PLC rack is regularly energized by its primary power supply module, the shelf life extends up to approximately 5 years, depending on ambient thermal conditions.

Q: Can this memory backup cell be replaced while the PLC system remains active?

A: Yes. The replacement procedure allows for hot-swap capability provided the main rack power supply remains fully energized during the physical swap. If the power supply is off when the old battery is disconnected, all uncommitted user memory configurations and logic parameters within the volatile RAM will be cleared.

Field Installation Guidelines

• Connector Orientation: Align the keyed slots of the 2-pin polarized connector with the physical header pins on the CPU or coprocessor circuit board. Do not apply excessive mechanical force, which can distort the terminal terminals or cause reverse polarity contact.
• Securing the Cell: Place the battery housing securely into the dedicated plastic retention clip molded within the module frame or door assembly to prevent mechanical displacement under continuous low-frequency industrial vibration profiles.
• Disposal Protocols: Spent units must be handled in accordance with standard industrial chemical recycling guidelines. Do not incinerate, crush, or expose the cell to temperatures exceeding the specified storage threshold of 85 deg C to prevent structural casing rupture.
