C-20 Description of Self-diagnosis Test Items
Check if 4D board is in place, read the ID of 4D board and logic version.
Analysis when test failed
If prompt “4D Board is not on the site.”，states that the 4D board is not in place or in –place detection
circuit is failed; if prompt “4D Driver Board logic version and board ID read error.”，there may be
communication malfunction between 4D board and DSP board.
Suggestion when test failed
Replacing 4D board is recommended.
C.1.42 Z1402 4D Driver Board Driver Circuit Test
Test Content
The super stratum test item：Z1301 4D Driver Board ID Test.
Set the Sin+ and Sin- driver circuit to output sine signal . after amplification ,AD will sample the
signal to judge the frequency and amplitude .Also include Cos+ and Cos- driver circuit.
Analysis when test failed
If prompt “Sin+ Cos+ Sin- Cos- driver circuit test FAIL.”，there may be malfunction on driver circuit.
Suggestion when test failed
Replacing 4D board is recommended.
C.1.43 Z1403 4D Driver Board Programmable Voltage Test
Test Content
The super stratum test item：Z1301 4D Driver Board ID Test.
Set the program high voltage PVPP and NVPP to output corresponding voltage, AD will sample the
voltage to judge the amplitude after amplification.
Analysis when test failed
If the test is FAIL，the theory value and sampling value of PVPP and NVPP will be prompted. You
may judge which power channel signal is failed according to the values.
Suggestion when test failed
Replacing 4D board is recommended.
C.1.44 Z1501 ECG Module Information Read Test
Test Content
The super stratum test item：Z0701 PC Module and DSP Interconnection Test.
Check if ECG board is in place and read ID of ECG board, logic version and software version.
Analysis when test failed
