An alarm is65 triggered if the rotation speed has dropped below a programmable limit. F AN64 Fan rotation speeds are reported in RPM (rotations per minute). An alarm is 65 triggered if the rotation speed has dropped below a programmable limit. Fan 66 66 readings can be divided by a programmable divider (1, 2, 4 or 8) to give 67 the readings more range or accuracy. This is important because some FANs 68 report only one 'tick' each rotation, while others report two - making 69 all readings twice as high. Not all RPM values can accurately be represented, 70 so some rounding is done. With a divider of 2, the lowest representable 71 value is around 2600 RPM. 67 the readings more range or accuracy.
