The Icom CM-3sO maintenance manual provides detailed instructions for setting up, operating, and troubleshooting the AC battery charger, including specifications for applicable battery packs, power supply requirements, and charging currents. It also describes the control mechanisms, circuit operations, and logic circuits involved in maintaining a constant charging current for different battery packs, ensuring proper functionality and safety during the charging process.
Manual Overview
The Icom CM-3sO AC Battery Charger maintenance manual provides detailed instructions for servicing and troubleshooting the charger. The manual emphasizes the importance of understanding the charging current control, which is managed by a conducting angle control circuit using a sawtooth pulse to regulate the SCR’s gate pulse. This ensures a constant charging current despite variations in battery pack output voltage. The logic circuit, controlled by switches S3 to S5, manages the charging process based on the battery type and state. Error diagnostics involve checking the status of the logic circuit and the charging current selector switches. Calibration and adjustments are primarily focused on ensuring the correct charging current is selected and maintained. Board-level guidance includes removing the cover and PC board for inspection or repair, with specific attention to not damaging internal wiring. The manual also details the specifications for applicable battery packs and provides a schematic diagram for further technical reference.
