Display Screen
The LCD display is highly configurable and can display various critical information including
pressure differential, flow rate, alarm status, menu options, and error messages. In addition, the
LCD display is used for programming the unit. When programming the unit, the display will show
menus, menu items, and current value of the menu item, depending on the specific programming
function being performed.
Room Indicator Colors
The screen icon is colored green (NORMAL) when the room pressure and/or other
configured measurements are adequate. This light indicates the room is operating
safely. If a set point cannot be maintained or an alarm limit has been reached, the
green light turns off and the red alarm light turns on.
The room icon is colored red (ALARM) when the room pressure and/or other
configured measurements are not within alarm limits. This light indicates the room is
not operating safely. The display screen will also indicate the type of alarm or an
emergency message.
The room icon is colored gray to indicate No Isolation mode. In No Isolation mode
the Model RPC30 will not alarm.
