Program Controller
Activation
At the configuration level with
ProG = EnA
Function
The current setpoint is determined exclusively by the program.
Eight programs with twelve segments each are saved to the controller and can be selected.
The functions which otherwise influence the setpoint, such as setpoint swapping and setpoint ramps,
as well as the start-up circuit and boosting for hot-runner control, are without function.
Program
Each of the twelve program segments is defined by means of segment duration, targeted setpoint and the control tracks,
and the program can be set to end upon completion of the first through the eleventh segment as well.
Sequence
StoP
The program has been completed or stopped, or hasn’t yet been started (after a reset).
The controller and the actuator outputs are inactive, relative limit value errors are suppressed.
The momentary setpoint is set to the actual value.
The program is started over again after it has been stopped.
run.X
The program has been started, possibly automatically after a reset (X stands for the current segment).
The controller and the actuator outputs are active, relative limit value errors are enabled.
Segment 1 is always executed when the program is started, and the initial setpoint is the actual value.
The program can be started and stopped with a binary input:
In1 = Prun
.
Wt.X
Same as for
run.X
.
If “wait until setpoint is reached” has been selected (with
WAit = YES
), the program waits until system deviation
amounts to only 2° C before activating the next segment.
