Programmer Description

The SERIES 9210 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, an optional temperature value, an optional atmosphere value, and an option value. The opcode determines how and if each of the three values are used.

Opcodes

NO-OPThis no operation code does nothing and is used as a place hold on programs that are less than 24 steps.

ALARM This alarm function is used to notify the operator that an operation is complete or that a manual action is required. The program waits until the alarm is acknowledged to proceed. The option is the alarm number to display.

ATM_INQ The atmosphere inquiry is used to wait for the actual atmosphere to reach the specified atmosphere setpoint.

The options are:

wait, reach within band;

wait up, reach or exceed the setpoint;

wait down, reach or be less than the setpoint.

The default band can be set under the Configuration menu and is typically 10 (i.e. 0.10 percent dissociation).

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 the program step if the inquiry is true and the atmosphere data as the program step if the inquiry is false.

CC_SP_L The Cascade Setpoint Limit opcode will allow the user to set the upper and lower limits for the cascade setpoint. The temperature data is the lower limit, and the atmosphere data is the upper limit.

DELAY This opcode is used when a short delay is needed. The option value is the delay time in seconds.

DEV_AL This deviation alarm opcode is used to turn the temperature or atmosphere deviation alarms ON or OFF.

The option values are:

OFF, turns OFF both the temperature and atmosphere alarms

TEMPERATURE, turns ON the temperature alarm and turns OFF the atmosphere alarm
