Setting AFMS Parameters  

Before Beginning  

Before setting an AFMS's parameters in AFMS, ensure that the Prerequisites on page 3 have been met.  

Caution: Select the appropriate application on the AFMS controller before configuring other settings.  

Changing applications after configuration will restore most parameters to their defaults. See "Selecting  

an Application" in the AFMS NetSensor Application Guide, found on any AFMS controller's product  

page.  

Setting the Parameters  

Select the Configure tab.  

1.  

For Supply Area, enter the measurement (in square feet) of the cross section where the supply airflow pickup  

2.  

tubes were installed.  

Note: For guidance about the location of the pickup tubes, see "Mounting the Supply Airflow Pickup Tubes"  

in the Airflow Measurement System Installation Guide, found on any AFMS controller's product  

page.  

Choose to either leave Enable Low Limit set to ON (the default), or to turn it OFF.  

3.  

4.  

Warning: ON is recommended to prevent freezing of equipment. If not needed (due to your  

equipment's particular nature), you might choose to turn it OFF.  

Either leave Low Temp Limit set to the default (37°F), or adjust the value.  

Note: If the mixed air temperature reaches the Low Temp Limit set here (and Enable Low Limit is set to  

ON) the outside air damper will modulate toward closed to prevent freezing of the equipment.  

For Stroke Time (Seconds), enter the time (in seconds) that it takes for the damper to go from 100% open to  

100% closed.  

5.  

6.  

For Damper Reverse Action:  

o

Select NORMAL if the greater the output signal to the damper actuator is, the more the damper opens (if  

10 volts = 100% open).  

o

Select REVERSE if the greater the output signal to the damper actuator is, the more the damper closes (if  

10 volts = 100% closed).  

For Actuator Voltage, select the voltage range of the damper actuator (2 to 10 volts or 0 to 10 volts).  

7.  

8.  

Select ON for Learn Damper Span.
