6. PROGRAM MODE
The Program Mode allows more complicated front panel control than the Local
Mode. The Program Mode allows a temperature control program to be entered
into the controller memory for subsequent execution as required. Up to 100
program steps may be entered. Multiple programs may be entered and executed
as long as the total number of steps in all programs does not exceed 100.
Programs are stored in non-volatile EEPROM memory. See Appendix 9.1 for
Sample Programs.
6.1 Description of a Program Step
Each program step has five data parameters, called substeps. The program
substeps are numbered 0-4. Except for special command steps (see Section 6.8),
each substep has a dedicated function as follows:
Substep 0is a setpoint temperature.
Substep 1 is the ramp time.
Substep 2is the hold time.
Substep 3is the next step to be executed. If this substep is specified as
100, the program will terminate after execution and the
display will show "End".
Substep 4 is the probe used for control. It can be specified as 0, 1, or 2 to
select the probe or mode to be used for temperature control, or
3 to 7 to effect special commands (see Section 6.8).
When displaying program steps on the LED display, the program step.substep is
displayed at the left side of the display and the data associated with that program
step.substep is displayed on the right as follows:
06.0 - 30.5The example above shows step 6, substep 0 contains the temperature data -30.5
Each program step contains all five substeps, regardless of whether or not each
step is used. Therefore, a complete program step is as follows:
