Figure 3: PresSura Operator Panel - Open
Green / Red light
The green light is on when all the conditions for proper room pressure are adequate. This
light indicates the isolation room is operating safely. If any of the room pressure
conditions cannot be satisfied the green light turns off, and the red alarm light turns on.
Operator Panel
A cover hides the operator panel. Sliding the door panel to the right exposes the operator
panel (Figure 2).
Digital Display
The alphanumeric digital display is a two line display that indicates actual room pressure
(positive, negative or no isolation), alarm status, menu options, and error messages. In
normal operation (green light is on), the display continuously scrolls information about
room pressure, and other variables programmed; flow, air changes per hour, etc. The
variables that scroll depend on the model of PresSura controller purchased and options
installed.
As an example, if an alarm condition occurs, the variable that normally scrolls
PRESSURE PRESSURE
NORMAL will change to read ALARM = *
* will state type of alarm; low pressure, high pressure, flow
When programming the unit, the display will change and now show menus, menu items,
and current value of the item, depending on the specific programming function being
performed.
Keypad
The keypad has six keys. The gray keys with black letters are user information keys. In
normal operation these keys are active. The gray keys with blue characters are used to
program the unit. The red emergency key has no function on the monitor and has been
disconnected. A thorough description of each functioning key is given below.
