Chapter Troubleshooting Power supplies within the equipment ..........2-1 Power supplies for ECG AMP (EE-20, EE-21) ........2-2 Symptoms and remedies..............2-3 The equipment is not started even if the power is set to “ON.”2-4 Operation with battery cannot be performed ......2-4 Troubleshooting on the power supply voltage on the main board ................
Chapter 2 Troubleshooting Outline Even if troubleshooting is performed, the trouble or the failure may not be solved. Refer to the description in this chapter as guidelines for repairing the equipment. Power supplies within the equipment As shown below, DC power voltages to be used for various devices (+24V, +12V, +5.0V, +3.3V, +2.0V, +1.8V, -5.0V, and -8.0V) are created within the equipment using AC power or DC battery power.
Chapter 2 Power supplies for ECG AMP (EE-20, EE-21) Since the ECG AMP is insulated, the power is supplied through a push/pull circuit using a pulse transformer (FT-2155). +5VF (+2.5VF): Main power supply for ECG AMP generated with the pulse transformer (FT-2155) and the regulator. VREF: Used as the reference voltage for ADC.
Troubleshooting Symptoms and remedies CAUTION If the parts mounted on the boards such as the MAIN BOARD (PCB-7085) is considered to have failed, do not replace the parts only but replace the entire board unit. If a trouble related to the power supply should occur, we recommend you to replace the power supply unit.
Chapter 2 The equipment is not started even if the power is set to “ON.” Check item Procedure/Remedy Place of check Power cable Check that the power cable is inserted into the Power cable receptacle and the AC adaptor. Check also that the DC plug DC plug is connected to the equipment.
Troubleshooting Troubleshooting on the power supply voltage on the MAIN BOARD Power supply voltage Procedure/Remedy Place of check +3.3V Check that +3.3V is supplied between C21 terminals on the MAIN BOARD. Check also that D2 stays on. If power is not supplied, the power supply unit may P5-5, 7 be faulty.
Chapter 2 Troubles related to charging operation Power supply voltage Method of Checking and Corrective Action Place to Check Power cable Check that the power cable is inserted into the Power cable receptacle.

Chapter 2 The keys cannot be operated. Power supply voltage Method of Checking and Corrective Action Place to Check Cable Check that the key panel relay cable is connected to Key panel relay cable the operation panel and the INTERFACE BOARD. Check the cable for break.
Troubleshooting Speaker does not sound. Power supply voltage Method of Checking and Corrective Action Place to Check Program setting Check the program setting to make sure that the Speaker program setting speaker is not set to OFF and that the volume is not set to extremely low level.
Chapter 2 Recording paper is not fed. Power supply voltage Method of Checking and Corrective Action Place to Check Connector Check that the motor cable is connected to the power Motor cable supply unit securely and that the motor cable is not P5-34 broken.
Troubleshooting Detachment of electrode cannot be detected with some leads. Since ECG input is of high-impedance circuit configuration, measurement of the part before the buffer IC is hard to be performed with a measuring instrument. It is therefore effective from the viewpoint of saving time to replace devices, thus locating failed parts.
