[1]
This test checks if the ADC hardware is functional. The main controller U10 establishes communication
with the ADC and checks if there are any error bits set for the ADC's status reporting.
624 Unable to sense line frequency
This test checks that the LSENSE logic input U17 is toggling. If no logic input is detected, the power
supply will assume a 50 Hz line operation for all future measurements.
625 I/O processor does not respond
This test checks that communications can be established between U17 (U10 for serial MY53xx6xxx) and
U4 (U752 for serial MY53xx6xxx) through the isolated (U6 and U7) (U751 for serial MY53xx6xxx) serial
data link. Failure to establish communication in either direction will generate an error. If this condition is
detected at power-on self-test, the power supply will beep and the error annunciator will be turned on.
626 I/O processor failed self-test
This test causes the earth referenced processor U4 (U752 for serial MY53xx6xxx) to execute an internal
ram test. Failure will generate an error.
630 Fan test failed
This test checks if the fan current is flowing. If the current is not detected at power-on self-test, the
power supply will beep and the error annunciator will be turned on. Fan test failure could likely induce
overtemperature condition in the power supply.
631 System DAC test failed
This test checks if the DAC hardware is functional. The main controller U17 (U10 for serial MY53xx6xxx)
sends a reference voltage data to DAC and converts the DAC output to digital data to see if the digital
data is within a valid range.
632 Hardware test failed
This test checks the status of voltage and current error amplifiers for the power circuit of output1. If
both amplifiers are not operational, the power supply will beep and the error annunciator will be turned
on.
[1] This error message is only applicable for serial MY53xx6xxx.
