"Basic Sanity Test"

The Operator Display Panel (ODP) is the interface device between the Fume Hood Controller

and the operator. Its main functions are to display normal, warning, and alarm conditions to

the operator. The ODP consists of a housing, three Light Emitting Diodes (LEDs), a liquid

crystal display (LCD), four buttons, and a portable operator's terminal port. See Figure 4. The

ODP buttons function as follows:

Horn Silence button – Pressing the Horn Silence button turns the audible alarm off for the

current alarm event.

Emergency Purge button – Pressing the Emergency Purge button removes contaminated

air from the fume hood by switching to an emergency exhaust flow level. The internal audible

alarm will sound. Emergency Purge automatically overrides any other control mode in the

Fume Hood Controller.
