Fume Hood Controller Owner's Manual

Low Speed Electronic Actuation

Alternately, when speed of response is not an issue, slower speed electronic actuation may

be used. This can be used when the change-of-state between High and Low can take place

in 15 seconds or more.

Pneumatic Actuation

The pneumatic actuator is connected to an exhaust flow control device in the fume hood

exhaust duct. The standard pneumatic actuator (Figure 8) used with the Fume Hood

Controller is the No. 3 unit. The No. 3 actuator is used because of its small size and quick

response time. The actuator has a deep drawn aluminum housing, a rubber diaphragm, and

a spring return rated at 8 to 13 psi. Pneumatic actuation requires two components, the

actuator and the transducer (AO-P module).

WARNING:

Due to the design, parameters and the response times required by the

Fume Hood Controller, the No. 3 actuator always must be replaced

with the same part or a Siemens Building Technologies, Inc. approved

equivalent. Any modifications that are not approved may affect the

safety and performance of the Fume Hood Controller.
