Programmer Description
The SERIES 9200 series Atmosphere/Temperature Recipe Programmer provides a convenient
operator interface and recipe programmer.
The programmer uses enhanced opcodes that reduce the number of steps required for a program.
Each step consists of an opcode, a temperature value, an atmosphere value, and an option value.
The opcode determines how and if each of the three values are used.
Opcodes
NO-OP This no operation code does nothing and is used as a place hold on programs that are less than 12
steps.
ALARM This alarm function is used to notify the operator that an operation is complete or that a manual
action is required. By use of the Passcode and Alarm Screen, up to 99 User Alarms can be
assigned, with a short text on each. Displayed during an active Alarm Condition. The program waits
until the alarm is acknowledged to proceed .
ATM_INQ the atmosphere inquiry is used to wait for the actual atmosphere to reach the value specified in
the atm (atmosphere) field.
The options are:
• wait, reach within band;
• wait up, reach or exceed the set point;
• wait down, reach or be less than the set point.
The default band can be set under the Configuration Menu and is typically 10 (i.e. 0.10 percent
carbon).
• The
SET_WAIT opcode will change the band limit
• The LIMIT opcode immediately following this opcode sets a time limit on the wait.
• A BRANCH opcode immediately following this opcode can be used to change the program flow
based on the inquiry results.
BRANCH The Branch opcode can change program flow based upon an inquiry opcode. The temperature
data is interpreted as a program step if the inquiry is true and the atmosphere data as a program
step if the inquiry is false. The DELAY opcode is used when a short delay is needed. The option
value is the delay time in seconds .
