7.2.1 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 displaying faults/warnings once the "reset signal" is
input.
To reset a fault/warning, use either of the following 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 or NO.2 fault, turn off the S-ON signal and then set the DI terminal
allocated with function FunIN.2 (ALM-RST) to ON.
To reset NO.3 warning, set the DI terminal allocated with the function FunIN.2 (ALM-RST) to
ON.
