FAN_FAULT1 & FAN_FAULT2
Threshold Registers
(FAN_FAULT1 & FAN_ FAULT2)
The Fan Fault Threshold Registers (FAN_FAULT1 and
FAN_ FAULT2) are used to set the fan fault threshold
levels for fan 1 and fan 2, respectively. The Fan Fault
Registers are 8-bit, read/writable registers that allow
the fan fault RPM threshold to be set in 50 RPM incre-
ments. The default setting for both Fan Fault registers
is 500 RPM (
0000 1010
). The maximum set point
value is 12750 RPM. If the measured fan RPM (stored
in RPM1 and RPM2 Registers) drops below the value
that is set in the Fan Fault Registers for more than
2.4sec, a fan fault indication will be given. F1F (bit
0<0>) and F2F (bit 1<0>) in the Status Register indi-
cate fan fault conditions for fan 1 and fan 2, respec-
tively. The FAULT output will also be pulled low in a fan
fault condition. Changing FFCLR (bit 7<0>) in the Con-
figuration Register will reset the fan fault bits in the Sta-
tus Register as well as the FAULT output. See
Register 6-2 for the Fan Fault Threshold Register 8-bit
format.
