Sash Setup and Calibration

NOTE:

Enter all measurements to the nearest .0.25 inch (0.635 cm).

Sash Setup 2957

Set REPORT to OVERVIEW.

Nine Combination Sash Configuration.

NOTES: Numbers on the sashes show how the sash is wired. After the

physical sashes are calibrated, the position of the sashes will display in POS

SASH 1, POS SASH 2, and so on.

The horizontal sash numbering in vertical sash 2 always starts with 7. For

example, if HZ PANEL CT = 4, then vertical sash 1 contains sashes 3 and 4

and vertical sash 2 contains sashes 7 and 8.

Determine the number of horizontal sash panels. This number includes the

horizontal sashes in both combination sashes. The segments must contain

the same number of horizontal sashes. Set HZ PANEL CNT to this value.

Measure the width of the vertical sash 1 in inches (cm). Set VSASH

WIDTHA to this value.

Measure the width of the opening in vertical sash 1 in inches (cm). Set

TRACK WIDTHA to this value.

Measure the height of the opening in vertical sash 1 in inches (cm). Set

PANEL HGHTA to this value.

Repeat steps 2 through 5 for vertical sash 2. Enter the values into VSASH

WIDTHB, TRACK WIDTHB and PANEL HGHTB.

Measure the width of the individual sash panels in inches (cm). Choose one

of the following:

NOTE: If segment A and segment B dimensions are the same, only

setup segment A.

–

If all the sash panels in both segments are the same width, set PANL

WDTH 03 to this value.

–

If all even horizontal panels are one size and all odd horizontal panels

are another size.

Set PANL WDTH 03 to the width of the odd sashes.

Set PANL WDTH 04 to the width of the even sashes.

–

If all panels are different sizes.

Set PANL WDTH 03 to the width of sash 3.

Set PANL WDTH 04 to the width of sash 4.

Set PANL WDTH 05 to the width of sash 5.

Repeat until all sashes are defined.

Measure the height of the top frame of sash 1 in inches (cm). The sash

frame holds the horizontal sash panels and occupies the outer edges of the

fume hood opening. Set TOP FRAME A to this measured value.

Top Frame Measurement with Air Foil Removed.

Open sash 1 until the top edge of the vertical sash is aligned with the top

edge of the bypass area. Measure the height of the sash opening in inches

(cm). Set BYPASS HGHTA to this value.

If there is no restriction on the bypass, leave BYPASS OPEN at the default

(100%). If the bypass area has an airflow restrictor covering the open area,

such as a perforated grille or louvers, estimate the open percentage of the

bypass area. Set BYPASS OPEN to the appropriate value.

11.

Repeat steps 8 through 10 for vertical sash 2. Enter the values into TOP

FRAME B, BYPASS HGHTB, and BYPASS OPENB.

12.

Measure the height of vertical sash 1 in inches (cm). Set VSASH HGHT1 to

this value.

13.

Measure the height of the vertical sash 2 in inches (cm). Set VSASH

HGHT2 to this value.

14.

Measure the fixed area of the fume hood in square feet (square meters).

Any fume hood leakage must be accounted for in this measurement. Set

FIXED AREA to this value.

NOTE: The fixed area of the fume hood is an area that remains open

regardless of sash position or movement. For example, most fume hoods

have an intake gap under the lower airfoil and above the cabinet of the fume

hood (typically a 1 inch gap). Also include 1% of the maximum open face

area in this calculation for other open areas, such as the space between the

sash and the track, and leakage.

15.

If the fume hood has a fixed panel in the sash opening of Segment A, locate

the position of the panel by measuring from the bottom of the sash opening

to the bottom of the fixed panel and enter the value into FPANEL POS A.

Measure the height of the fixed panel and enter the value into FPANEL HGT

A. Repeat step 15 for Segment B.

Sash Calibration

NOTE:

It is recommended that the vertical sash be calibrated before the horizontal

sashes.

Starting with the first side, side A.

Set CAL SASH NUM to 1. It is recommended that the vertical sash be

calibrated before the horizontal sashes.

Set CAL SASH LOC to MIN for minimum opening.

Slide the vertical sash to the closed position. Set CAL SASH POS to 0

unless a physical stop prevents the sash from fully closing. If a physical stop

is present, 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.

When the sash aggregator accepts the reading, the minimum position value

will be automatically entered into POS SASH 1.

Set CAL SASH LOC to MAX for maximum opening.

Slide the vertical sash 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. When the sash aggregator accepts the

reading, the maximum position value will be automatically entered into POS

SASH 1 and CAL SASH POS will revert back to 257.

10.

Slide the sash panel to be calibrated to the far right. Measure the distance

from the left end of the track to the left edge of the sash panel. Set CAL

SASH POS to this value. When the sash aggregator accepts the reading,

the maximum position value will be entered into POS SASH 3.

11.

Set CAL SASH NUM to 0or to the next number of the horizontal sash panel

to be calibrated. This locks to sash calibration into the sash aggregator.

12.

Repeat Steps 7 through 11 for the remaining sash panels.

13.

Repeat all steps for the second side of the hood, side B. The vertical sash

will be POS SASH 2 and the horizontal sashes will be POS SASH 7 through

POS SASH 10.

Sash Calibration Verification

Close the vertical sash fully and verify that the value displayed at POS

SASH 1 is at the minimum that was set during calibration. Open the sash

half way and verify that the value displayed at POS SASH 1 is equal to the

measured value. Open the sash fully and verify that the value displayed at

POS SASH 1 is at the maximum that was set during calibration. See Table

Sash/Point Wiring

Repeat this verification procedure for the second vertical sash panels using

the appropriate corresponding points. See Table

Sash/Point Wiring

Slide the horizontal sash panel 3 to the left and verify the value displayed at

POS SASH 3 is at the minimum that was set during calibration. Slide the

sash to the middle of its range and verify that the value displayed at POS

SASH 3 is equal to the measured value. Slide the sash to the right and

verify that the value displayed at POS SASH 3 is at the maximum that was

set during calibration. See Table

Setting External Face Area Input

Skip this section if you are only using one SOAM, leave values at default.

AI can be set up as an input for external face area.

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 represented when the face area is equal

to 0.

2. Set MIN EXTVOLTS to the voltage corresponding to 0 face area from the input

signal source. (default = 1.0 Vdc)

The resulting area displays in point EXTERNAL A.

NOTE:

If no external area input is be connected to the AI, make sure MAX EXT AREA =

0 (default). This disables the alarm feature that fails the FACE AREA point when

the input signal drops below 1 Vdc.

Setting Face Area Output Range

1. Set REPORT to FACE AREA OUT.

2. Set MAX FACE A to the maximum expected face area for the fume hood, plus

approximately 10%. Example: If the maximum face area is 9 sq ft, set it to 10.

FACE A OUT is now active and a proportional 1 to 10V signal can be read

on AO. 1V equals 0 sq ft and 10V = MAX FACE A.

3. Set AO DEADBAND to the desired value.
