Core Functions

1. Data Retention: Preserves critical control data, recipes, and parameters during power failures for up to 10 years.

2. Power Backup: Supplies stable 3.6 VDC to the controller’s memory and RTC during mains interruptions.

3. Low‑Battery Monitoring: Provides status signals to the CPU for early warning and scheduled replacement.

4. Hot‑Swap Capability: Enables battery replacement without stopping the control process.

5. Redundant Operation: Supports dual‑battery setup to eliminate single points of failure.

6. Long‑Term Reliability: High‑energy‑density lithium chemistry ensures long service life and wide temperature tolerance.

Application Scenarios

• Process Control Plants: Chemical, water/wastewater, food/beverage, and pharmaceutical facilities requiring uninterrupted data integrity.

• Manufacturing Lines: Packaging, assembly, and material handling systems with critical recipe and parameter storage needs.

• Industrial IoT & Remote Monitoring: Unattended sites where power reliability is low and data loss must be avoided.

• Legacy AC31 System Upgrades: Replacing aged backup batteries in existing Procontic CS31/AC31 installations.

• High‑Availability Systems: Redundant control setups for maximum uptime and data security.

Usage and Maintenance Instructions

• Installation: Mount on DIN rail, connect to the CPU’s dedicated backup port; allow 10 mm clearance for ventilation.

• Wiring: Use the supplied cable; avoid bending or damaging the connector pins.

• Commissioning: Verify battery status via controller software; confirm low‑battery alarm functionality.

• Routine Maintenance: Inspect annually; replace every 8–10 years or when low‑battery alert activates.

• Replacement: Perform hot‑swap if supported; disconnect old module, install new one, and verify data retention.

• Environment: Operate within -20°C to +60°C; avoid direct sunlight, moisture, and corrosive gases.

• Disposal: Dispose of used batteries per local regulations for hazardous waste; do not short‑circuit or incinerate.
