Restricted 2015-11-04
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.
Setting ODP Display
Set ODP DISPLAY to the desired value. Values are CFM or MODE. In CFM, the ODP
displays the exhausted CFM. Use the table below to set the value. The default value is
MODE.

Setting Hi and Low Warn Limits
Skip this step unless there is a special requirement on the job; the default will be used.
1.
Change report to
STARTUP
.
2.
Set HI WARN LMT and LOW WARN LMT.
These limits are defined as a percentage of the controlled setpoint, meaning
that the alarm limits will be closer as the EXH STPT decreases. The default
values are 135% and 85% respectively. These points may be adjusted to
meet customer requirements.
