Fume Hood Specific Sash Setup and Calibration

Siemens Industry, Inc. Start-up Procedures 140-1321
Restricted 2015-11-04
16.
Close the sash fully and verify that the value displayed at VERT SASH1 is at
the minimum set in Step 9. Open the sash half way and verify that the value
displayed at VERT SASH1 is equal to the measured value. Open the sash
fully and verify that the value displayed at VERT SASH1 is at the maximum
set in Step 12.
17.
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.
18.
Proceed to
External Face Area Input Setup
.
Dual Vertical Sash (Setup and Calibration)
WARNING
The application cannot detect a broken wire to the analog input for the second sash.
An external sash aggregating device should be used to calculate the face area for all
fume hoods with more than one sash.
1.
Set REPORT to
DUAL VERT
.
2.
Measure the width of sash 1 in inches (cm). Set VERT WIDTH1 to this value.
3.
Measure the height of the vertical sash in inches (cm). Sash 1 and Sash 2
must be the same height. Set VSASH HGHT1 and VSASH HGHT 2 to this
value.
4.
Measure the distance the vertical sash can travel in its track in inches (cm).
This value does not have to be equal to VSASH HGHT1. Set TRACK HEIGHT
to this value. The TRACK HEIGHT must be the same for both vertical sashes.
5.
Measure the width of sash 2 in inches (cm). Set VERT WIDTH2 to this value.
Vertical Sash Fume Hood with Bypass Area Open and Closed.
6.
Open the sash until its top edge covers the bypass opening. Measure the
height of the sash opening in inches (cm). Set BYPASS HGHT to this value.
