During the use of Nihon Kohden Cardiolife TEC-7621C Defibrillator,
if there is a problem with the Relay Unit HV-761V, an error code
will be displayed. Next, take a look at what the different error
codes mean:
1. A501: During standby mode, the HV capacitor has more than 1 J
energy more than one continuous second
2. A512: When charging starts, the high-voltage capacitor energy
does not reach 1J within 2 seconds.
3. A513: The energy did not reach the selected energy within the
specified time.
4. A524: After charging, the capacitor energy drops to the
specified value for each energy.
5. A527: After charging, the capacitor energy is approximately 15%
higher than the selected energy.
6. A529: After charging, the actual charging capacity is different
from the selected capacity.
7. A556: Internal discharge takes more than 20 seconds to complete.
8. A566: 20 seconds after adjusting the internal discharge, the
voltage of the high-voltage capacitor did not reach the target
value.
9. A585: The high voltage capacitor voltage exceeds the specified
voltage.
10. A587: When using disposable pads, 12.5% or more of the charged
energy remains in the high-voltage capacitor after 2 seconds of
external discharge.
