Setting Display Weight
Set DISPLAY WT to a value of 0 through 100% (default is 100%). The suggested value
is 30%.
NOTE:
If DISPLAY WT is set to 100%, the exhaust volume displayed at the ODP may
fluctuate rapidly. This rapid fluctuation is due to the constant adjustments of the FHC.
When DISPLAY WT is set to a value less than 100%, the exhaust volume displayed
at the ODP is a weighted calculated value. This value is used to stabilize the ODP
displayed value only; it has no effect on the control sequence.
If you set DISPLAY WT to zero, the Operator Display Panel will “freeze” at the last
read value. Setting DISPLAY WT to a value other than zero (suggested value is 30%)
allows the Operator Display Panel to update the displayed exhaust volume.
Setting Display Resolution
Set DISPLAY RES to a value of 0 through 255 cfm (0 to 120 lps). The default is 20 cfm
(9.4 lps). This value is used as a COV limit for face velocity readings displayed at the
ODP only; it has no affect on the control sequence and has no effect on values going
across the network.
NOTE:
If you set DISPLAY RES to zero, the Operator Display Panel will “freeze” at the
exhaust volume setpoint EXH VOL STPT. Setting DISPLAY RES to a value other
than zero allows the Operator Display Panel to update the displayed exhaust volume.
Setting High Flow Setpoint
Set EXH HI STPT to the desired air volume. Values are in CFM (LPS). The valid range
of values will depend on the size of the exhaust duct.
Setting Low Flow Setpoint
Set EXH LO STPT to the desired air volume. Values are in CFM (LPS). The valid
range of values will depend on the size of the exhaust duct.
