5. After you enter and verify your changes, press F2 (Accept Control Point) to save the new data.
The Electronic Pressure Control Multibus PCB compares the data changes made on the screen with
the application-specific pressure limits. If the new settings are within the limits, they will be accepted
and applied to the analysis.
If the Set Point (SP) or Ramp Rate (Rate) values are not within the set limits, the * PRES BD ALARM
* flashes on the screen’s message line. Pressure Zone specific alarms also cause the zone name to
flash. To identify the type of alarm, press Escape to return to the Pres & Temp Control Screen, then
press F4 (Alarms) to display the Alarm Screen. After noting the type of alarm triggered and
consulting the Applications Package for the set limits, clear the alarm, return to the Manual Pressure
Control Screen, and change the entries to values within the set limits. If the new settings are
accepted, there will be no * PRES BD ALARM * display on the screen after F2 (Accept Control Point)
is pressed.
Calibrate Zone settings are made in the factory and are not intended to be changed.
Pressure Configuration Table
This screen allows you to enter a pressure range, change the configuration choices, and change the
pressure zone names. Always check the original application-specific pressure limits listed in the
analyzer's Data Package to ensure any changes are valid. To access the Pressure Configuration
Table perform the following steps:
1. On the Background screen press F2 (Manual Control).
2. On the Manual Control Mode screen press F4 (Press. & Temp. Control).
