13A and 13D. Fan Speed Sensor Constant
The Fan Speed Constant is the number of pulses the fan speed sensor
generates in one revolution of the monitored fan. This is typically the
number of teeth (sense points) on the fan. The fan speed constant can be
entered as a decimal with 0.01 resolution. Entering a value of zero (000.00)
disables the fan speed function. The Fan Speed Sensor Constant is
accessible only if the Number of Fan Speed Sensors has a value other than
0. (
Figure 32 ) shows the display with a Fan Speed Constant of 34.00
pulses per revolution.

enabled or disabled by selecting the ON or OFF message. Use the
SELECT switch to advance one step to the right of the right most digit, then
press the SET switch to toggle between ON and OFF. (
