Description
0
Alarm Speed
Read Only
This bit is set to “1” when fan is running at alarm speed. Once read, this bit
will not reassert on next monitoring cycle, even if the fan is still running at
alarm speed. This gives an indication as to when the fan is running full-speed,
such as in a
THERM
condition.
This bit is set to “1” if fan becomes stuck or is running under speed. Once
read, this bit will reassert on next monitoring cycle, if the fan failure condi-
tion persists.
“1” indicates Remote high temperature limit has been exceeded. If the tem-
perature is still outside the Remote Temp High Limit, this bit will reassert on
next monitoring cycle.
“1” indicates Remote low temperature limit exceeded (below). If the tempera-
ture is still outside the Remote Temp Low Limit, this bit will reassert on next
monitoring cycle.
“1” indicates Remote temperature Therm limit has been exceeded. This bit is
cleared on a read of Status Register 1. Once cleared, this bit will not get reas-
serted even if the
THERM
condition persists.
This bit is set to “1” if a short or open is detected on the remote temperature
channel. This test is only done on power-up, and if set to 1 cannot be cleared
by reading the Status Register 1.
“1” indicates Local Temp High Limit has been exceeded. If the temperature
is still outside the Local Temp High Limit, this bit will reassert on next
monitoring cycle.
“1” indicates Local Temp Low Limit has been exceeded (below). If the tem-
perature is still outside the Local Temp Low Limit, this bit will reassert on
next monitoring cycle.

“1” indicates Local temperature Therm limit has been exceeded. This bit clears on a read
of Status Register 2. Once cleared, this bit will not be reasserted even if the

Set to “1” when
THERM
is pulled low as an input. This bit clears on a read of Status
Register 2. The fan also runs full-speed.
