6.6.5 TRLYS1D Diagnostics

Diagnostic tests to components on the terminal boards are as follows:
• The solenoid excitation voltage is monitored downstream of the fuses and an alarm is latched if it falls below 12 V dc.
• If any one of the outputs goes unhealthy a composite diagnostics alarm, L3DIAG_xxxx occurs.
• Each terminal board connector has its own ID device that is interrogated by the I/O pack. The connector ID is coded into
a read-only chip containing the board serial number, board type, revision number, and the JA1/JR1/JS1/JT1 connector
location. When the chip is read by the I/O pack and mismatch is encountered, a hardware incompatibility fault is created.
• Details of the individual diagnostics are available in the configuration application. The diagnostic signals can be
individually latched, and then reset with the RSTDIAG signal if they go healthy.
