11.10.4 Transistor regulator errors

All errors generated by or within the transistor regulator [A1] are communicated to the main control card [A2]. The fault conditions are then displayed as error or caution codes according to the List of error codes on page 28. However, there is a status LED on the transistor regulator which displays the current status of the regulator.

The table below depicts the error codes that may be shown by the STATUS LED or read using the hand-held terminal.
