The manual for troubleshooting Chipper Check power supplies covers the setup and operation of the Input Side Supply and Output Side Switching Supply, detailing how to measure voltages and waveforms using specific ground references. It also provides guidance on isolating problems within the power supply using conventional measurement techniques and includes diagrams showing the location of power supply components on different versions of the circuit board.
Manual Overview
The manual for troubleshooting the Sencore Chipper Check power supplies provides detailed guidance on diagnosing and resolving issues within the device’s power supply systems. The Chipper Check includes two main power supplies: the Input Side Supply and the Output Side Switching Supply. The Input Side Supply is filtered by capacitor C28908 and should measure approximately 5 volts, indicating a good supply when referenced to S1 ground. The Output Side Switching Supply, driven by IC U28904, produces an isolated 5 volts, with voltages referenced to S ground. Troubleshooting involves using conventional voltage and waveform measurements, with reference points provided in Figure 2 for accurate diagnostics. The manual also highlights the importance of using correct grounding points: S1 ground for the input side and S ground for the output side. Component locations for both old and new circuit board versions are illustrated in Figures 3 and 4, aiding technicians in identifying parts for calibration and adjustments.

Troubleshooting & Error Codes
The manual provides guidance on troubleshooting the Chipper Check power supplies. It describes the power supply system as consisting of an Input Side Supply and an Output Side Switching Supply, both providing approximately 5 volts to different parts of the Chipper Check circuitry. The Input Side Supply voltage is filtered by C28908, and voltage measurements are referenced to S1 ground. The Output Side Switching Supply uses a more complex switching power supply, with voltages referenced to S ground.
For troubleshooting, conventional voltage and waveform measurements can be used, with reference voltages and waveforms provided in Figure 2. It is important to use S1 ground for measurements on the input side of the transformer and S ground for the output side. The manual also includes diagrams showing the location of power supply components on both old and new circuit boards, with input and output ground locations identified.
