5. After you enter changes in the Set Point or Ramp Rate fields, press the F2 (Accept Control Point)
soft key to save the new data.
Data changes made on the screen go to the DTC Backplane PCB, which compares the new settings
with the application-specific temperature limits. If the new settings fall within the limits, it accepts
them and applies them to the analysis.
If entries in the Set Point or Ramp Rate fields fall outside the set limits, the * TEMP BD ALARM *
flashes on the screen's message line. Temperature 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 the F4 (Alarms) soft key to display the Alarm Screen. After you note the type of alarm
triggered and consult the Data Package for the set limits, clear the alarm, return to the Manual
Temperature Control Screen, and change the entries to values within the set limits. If the DTC
Backplane PCB accepts the new settings, there will be no * TEMP BD ALARM * display on the
screen after you press the F2 (Accept Control Point) soft key.
Zero All Zones and Span All Zones settings are made in the factory and are not intended to be
changed.
