detection IC will automatically detect the number and the position of fans
on the board.
should not be relocated before turning off the power. Or, the IC will
identify the fan as malfunction.
The fan LED
will be on all the time when all the fans are well functioned. The LED light
will flash and buzzer
generated the beep sound when there is any fan fails.
Check all the fans and replace the faulty fan
when you hear the beep sound or see the
LED flashing light on the
board. Note that the position of the fan must be identical after
replacement, otherwise, the alarm will keep ringing..
MUST be the 3 pin clock type of fan.

buzzer will generate a beep sound when a thermal sensor fails. SI, S2
LED will be flashing in mean time. (You can
easily identify which set is overheating)
The buzzer will stop beeping when pressing RESET button. If the LED is still
flashing, please change the fan
right away. Once the failure parts have been identified, the function will
be back to normal.
3. When the system is not
functioning, here are the possible problems:
Malfunctioning thermal sensor.
NOTE: Make sure to turn
off the power before moving the control board. It's highly possible to
damage the IC or the circuit board when
unplugging the 4 pin connector without turning off the power.
Some chassis are equipped with an alarm rest
switch and front LEDs that will flash when the alarm goes off. However, the IS-F08 can be
used without those. In which case, the beeper only will make you aware
of a fan or temperature problem, and it will stop when the faulty part is
replaced. However, any standard reset switch can be connected to the IS-F08
to stop the beeper.
