High Speed Electronic Actuation
The High speed electronic actuator assembly consists of two parts, the electronic actuator
and the interface board. The actuator is connected to the exhaust flow control device in the
fume hood exhaust duct. The electronic actuator assembly is used because of its small size
and quick response time.
CAUTION:
Due to the design parameters and the response time required by the Fume Hood
Controller, the assembly 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.
