C-12 Description of Self Test Items
If the test result is FAIL, it is recommended to check the power-on of the electrical
ascending/descending control board and the connection among the cables.
C.1.24 Z0802 Lift Control No Load Voltage Test
Top test item
Lift Control Interconnection Test
Test Content
Test software sends the order to get the electrical ascending/descending control board self-tested
via 12C, and reads the idling voltage.
Analysis to Test Failure
If the test result is FAIL, it indicates the idling voltage does not meet the requirement.
Suggestion to Test Failure
It is recommended to replace AC-DC;
C.1.25 Z0901 MF FPGA and PHV ARM Interconnection Test
Top test item
PC Module and MF FPGA Interconnection Test
Test content
Test whether UART communication between MF FPGA and PHV ARM works well. Send the order
through PHV serial port drive, and re-read the data via the port.
Analysis to test failure
The drive goes wrong if the test result appears Error.
UART interconnection between FPGA and PHV ARM goes wrong if the test fails.
Suggestion to failure test
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device if Error re-appears.
C.1.26 Z0902 PHV Board Programmable Voltage Test
Top test item
MF FPGA and PHV ARM Interconnection Test, TRC XCVR Bus Test
Test Content
Three sets of programmable voltages from low to high (PHV voltage and CW voltage). Read the
voltage via PHV board serial port and make the judgment.
Analysis to Test Failure
The drive goes wrong if the test result appears Error.
The error may occur between the PHV and CW voltage if the test fails.
Suggestion to Test Failure
Restart the device to perform the self test if the test result appears Error. It is necessary to restore
the device if Error re-appears.
If the test result is still FAIL, it is recommended to replace PHV power supply board (TR64 error
may lead to PHV or CW voltage failure).
