The air velocity sensor calibration cycle begins within three minutes of an application
start-up or initialization, depending on the controller’s address.
Setting Display Units
Set ENG UNITS to English or System International (SI) units (default is English units)
depending upon which unit (fpm or m/sec) you want displayed at the Operator Display
Panel.
NOTE:
All measurements entered during the start-up sequences may be entered as either
English or SI values (listed in parentheses after the English unit), depending upon
which unit has been selected using the Metric/English Units button on the appropriate
tool.
Testing the Operator Display Panel
Test the Operator Display Panel (ODP) as follows:
1. Set LAMP TEST to ON.
2. Verify that all visual display functions of the ODP appear and that the audible alarm
sounds continuously.
3. Set LAMP TEST to OFF.
Setting Duct Area
If provided, enter the duct area (sq ft or sq m) into DUCT AREA.
If you do not know the duct area, use the appropriate tool to calculate it, or use one of
the following equations to calculate it manually:
Area =
Round Duct
Rectangular Duct
Area in Sq. Ft.
(Dimensions in inches)
π x R
2
/144
(where R = radius of duct)
Width x Height/144
Area in Sq. M
(Dimensions in centimeters)
π x R
2
/10,000
(where R = radius of duct)
Width x Height/10,000
NOTE:
When entering the controller definition for a controller at the field panel, do not enter a
duct area. (Choose
N
for none when prompted for the duct shape.) This controller
does not send the value of air volume to the field panel in velocity (fpm). Instead, it
uses volume (cfm) so a conversion is not necessary.
