FUNCTIONAL DESCRIPTION:

IC693ACC301 is a Lithium Backup Battery manufactured and designed by General Electric as part of the 90-70 Series used in PLC Systems. It is a long-life lithium backup battery designed to maintain the memory contents of the CMOS RAM located beneath the cover plate at the bottom of the power supply plate. This battery is crucial for preserving system data and configuration settings when the PLC (Programmable Logic Controller) is powered off. The battery connects to the power supply’s printed circuit board (PCB) via a pair of wires attached to a small Berg female connector. This connector plugs into a corresponding mating connector on the PCB. The battery itself is mounted on a plastic clip affixed to the inside of the cover plate, ensuring stable placement and connection within the PLC system.

BATTERY LOW WARNINGS:

• Red BATT LED: The power supply module features a red BATT LED that illuminates when the battery level is low. However, in cases where the PLC is housed within an enclosure, this visual indicator may not be easily visible.

• PLC Fault Table: The PLC Fault Table is updated with a battery-low message. This requires a programmer to be connected to the PLC to review and address the alert.

• System Reference Bits: Certain system reference bits are set to logic 1 when the battery is low. These bits can be monitored, and if the condition is detected, a warning light on an operator panel can be activated, or a warning can be communicated to an operator interface terminal.

BATTERY REPLACEMENT AND MEMORY PROTECTION FACTORS:

• When planning battery replacement and memory protection in a PLC system, it is essential to consider the criticality of the application. In high-stakes operations, even brief downtime can lead to significant losses. Frequent battery replacement is advisable in such scenarios to minimize risks. The cost of a battery is relatively low compared to the potential impact of a shutdown.

• Another key factor is the ease of accessing and loading a backup program. Ensure the backup program is readily available to maintenance personnel and that they are trained to load it. Having a computer or device equipped with GE Fanuc programming software on-site is essential for seamless recovery in case of failure.

• A preventive maintenance program is also crucial. Regularly scheduled maintenance helps ensure batteries are replaced on time, reducing the risk of unexpected disruptions. Many users align battery replacements with annual shutdowns, maintaining a log to track battery life and replacement schedules.

• The physical accessibility of the PLC is another important consideration. If the PLC is located in a remote or hard-to-reach area, additional planning is required to manage battery replacements effectively. These factors should be taken into account during system design or maintenance planning.

• Compliance with safety codes is mandatory, as some regulations may not permit battery replacement while the system is powered. Adhering to safety standards and ensuring personnel follow proper procedures are vital to prevent accidents during maintenance.
