SPT - Konica FT1

Comprehensive service manual for the Konica FT-1 motor system, providing in-depth technical documentation on the motorized functions of this classic SLR camera. The manual delivers detailed mechanical and electrical guidance for technicians servicing the camera's drive train and automation circuits. Multiple sectional views—front, bottom, and rewind side perspectives—illustrate motor construction and layout. The documentation covers the EE control circuit operation, release magnet function, and full technical specifications including AE coupling range (EV 0.7 to EV 19 at ISO 100 with f/1.8 lens) alongside precision calibration data for VO2 voltage adjustment, automatic exposure control, and shutter curtain timing. Film transport mechanics, diaphragm drive assembly with its gear train, and mirror motor and film wind motor relay circuits are explained in operational detail. The disassembly section offers systematic removal and reinstallation procedures for critical motor components, while the calibration procedures cover VO2 voltage tuning, exposure compensation, and shutter curtain travel time measurement. Circuit schematics pinpoint component locations, amplifier configurations, and electrical contact paths throughout the system. A troubleshooting guide addresses practical repair scenarios—mirror motor faults, shutter resistor anomalies, and contact deterioration—with clear symptom identification and corrective steps to restore proper motor function.
