Operator Display Panel
The Operator Display Panel (ODP) includes a custom
designed package for visual and audible indication of
fume hood operating conditions and push-buttons for
emergency mode operation, alarm silence and user-
defined auxiliary functions. The panel is mounted on
the fume hood in an easy-to-access location and will
fit over an unused hood electrical box or over pre-
drilled holes. RJ-11 type connectors provide
termination to the Fume Hood Controller and for the
Portable Operator’s Terminal. One Operator Display
Panel is supported per Fume Hood Controller.
The Operator Display Panel supports the following
functions:
l Digital display of face velocity in FPM (MPS)
l Green, yellow and red status lights
l Emergency purge push button
l Alarm horn with silence push button
l Auxiliary push buttons for more information
l Animated Graphics to encourage users to close
sashes when not using the hood
The face velocity display also indicates high and low
alarm conditions, emergency purge activation, and
diagnostic failure mode conditions when the controller
is in the minimum flow mode. Face velocity FPM
(MPS) display may be blanked as an option for
applications where the user does not desire the face
velocity reading.
