5.1 Fault and Warning Grading
Fault and warning grading
Faults and alarms are graded into the following three levels based on degree of severity: NO.1 > NO.2 >
NO.3.
NO.1 non-resettable fault
NO.1 resettable fault
NO.2 resettable fault
NO.3 resettable warning
"Resettable" means that the keypad stops displays of faults/warnings once the "reset signal" is input.
To reset a fault/warning, use one of the following two methods:
Set 200D-02h=1 (fault reset enabled).
Enable the rising edge of the control word 0x6040 bit7 on the host controller.
To reset a NO.1 fault and a NO.2 fault, turn off the S-ON signal and input the fault reset signal.
To reset a NO.3 warning, directly input the fault reset signal.
