10.
Slide the sash panel to be calibrated to the closed position. Measure the
distance from the lower end of the vertical track to the bottom of the sash in
inches (cm). Set CAL SASH POS to this value.
11.
Set CAL SASH LOC to
MAX
for maximum opening.
12.
Slide the sash panel to be calibrated to the open position. Measure the
distance from the lower end of the track to the bottom edge of the sash panel
in inches (cm). Set CAL SASH POS to this value.
13.
Repeat Steps 9 through 13 for the remaining sashes.
14.
Set CAL SASH NUM to 0 to turn the calibration sequence OFF.
15.
Slide sash panel 1 to the middle of its range. Verify that the change in value of
VERT SASH1 matches the change in sash panel position. Repeat this
verification procedure for the remaining sash panels using the appropriate
corresponding points. See the Table
Multi-Vertical Sash/Point Wiring

16.
Set FAIL AREA to a desired fail-safe value for the face area, the default value
is 0 square feet. This value is used in the event of a sash sensor failure as the
default face area opening. When a sash sensor fails, this value will be used to
calculate what the exhaust flow should be. It is typically set to 1/2 of the
maximum open area.
WARNING:
Pay careful attention to the value entered in FAIL AREA. A value
too low may not provide enough exhaust flow for safe operation of a Fume
Hood should a sensor fail.

Proceed to
External Face Area Input Setup
.
Setting External Face Area Input
AI3 can be setup for different functions. Only one function can be used at a time. When
using the input as external face area, the input can’t be used for measuring the
exhaust volume signal.
1. Set MAX EXT AREA to the area corresponding to 10 volts from the input signal
source.
The next step allows the minimum voltage to bet set to a value other than 1
(default). The minimum voltage is output when the area is equal to 0.
2. Set MIN EXTVOLTS to the voltage corresponding to 0 area from the input signal
source. (default is 1.0 Vdc)
The resulting area displays in point EXTERNAL A.
