increment if needed. This process is repeated until the temperature is within ±1°C of the
specified set point. The amount of each incremental actuator movement and the specified time
between readings is user adjustable in the Recalibration screen. The time intervals are set to be
just longer than the response time for the temperature to stabilize after a move of the actuator,
typically 5 to 10 seconds.

3.2 Touch-Screen Display
The Omron, Touch-Screen Display mounted on the front panel of the electrical enclosure is the
user interface for the unit. When the unit is powered up, the Main Menu screen will appear
with buttons to access additional screens such as the System Status screen. The System Status
screen is the main informational screen and contains the current status of the unit, as well as
touch switches for operating actuated valves and performing other functions on the unit.
Moving from screen to screen and setting switches is a simple matter of touching the surface of
the display in the area of the screen indicated. For example, pressing the box on the display
labeled “MAIN MENU” would return the display to the main menu, and pressing the box
labeled “OPEN” would open the steam valve on the unit.
The ability to operate or change any settings to the unit via the touch-screen display is
password protected to prevent unauthorized personnel from access. There are two types of
passwords, the “operational password” and the “administrative password”. The “operational
password” is located on the Main Menu screen. The “operational password” is actually two
simultaneous keystrokes; the first is located in the area above the “PRESS FOR SYSTEM
STATUS” button or to the left of the “DATE” label and the second is located above the
“PRESS FOR TEMP TRENDING” button and to the right of the “TIME” label. When these
two areas are depressed, the “operational password” will activate and then operation functions
can be made in any of the screens for a period of fifteen minutes, after which the lockout will
automatically reset. The actual position for the operational password is indicated in the
Appendix. The “administrative password” allows access to changing controller parameters,
setting the date or time, and modifying alarm set points/delay timers.
In order to enhance the lifetime of the electroluminescent screen a screen saver function is
available which will darken the screen if there is no activity for a period of ten minutes.
Touching any area on the display will return the screen to normal, illuminated operation.
Pictures of all touch-screen displays are shown in the appendix of this manual.
