Press "SW7" on the master unit to confirm fault query.
Select a fault to be queried by pressing "SW1 (UP)" or "SW2 (DOWN)". LED3 alternately displays
the historical fault code and module address in an interval of one second in the sequence of fault records.
LED2 displays the fault sequence number. If there not historical faults, LED2 and LED3 display ―00‖ by
default. Up to five historical faults can be queried. The faults that can be queried are as follows:
