Procedure of the program control:
The first step is to determine whether the program controller should run after a fixed time
grid, or whether the respective step temperature must first be reached in order to reach the
respective holding phase. (See parameter "Continue if")
You should also consider how the program controller should control the temperature after
the end of the program. Three options are available: Setpoint 1, Last setpoint and Repeat.
For more details, see "Program End".
The number of steps [1 ... 8] must also be defined.
Now the time and temperature values for the desired steps must be entered in the "Setting
the program steps" screen.
One step always involves ramp duration and dwell time. The ramp duration determines the
time in which the setpoint is steadily increased from the previous temperature to the tem-
perature of the current step. The dwell time is the duration of the current step temperature.
An exception is the ramp for the first step. Since the first step does not have a preliminary
temperature, the ramp for all zones starts here with the current actual value of the first acti-
vated zone and ends at the temperature of step 1.
The ramp duration can be switched off by setting it to zero.
The dwell time is the duration of the current step temperature. If the parameter "Switch on"
is set to "Temp. reached", the dwell time does not start until all zones have reached the
step temperature.
After a network interruption with the program controller running, the program controller re-
activates in the step at which the interruption took place.
