7.3.5 Segment type
Ramp- seg-
ment (time)
With a ramp segment (time), the set-point runs linearly from
the start value (end of previous segment) towards the target
set-point (Sp) of the relevant segment during time Pt (segment
duration).
Ramp- seg-
ment
(gradient)
With a ramp segment (gradient), the set-point runs linearly
from the start value (end value of previous segment) towards
the target value (Sp) of the relevant segment. The gradient is
determined by parameter Pt.
Hold
segment
With a hold segment, the end set-point of the previous segment
is output constantly during a defined time which is determined
by parameter Pt.
Step
segment
With a step segment, the program set-point goes directly to the
value specified in parameter Sp. With configured control devia-
tion alarms, the alarm is suppressed within band monitoring.
End
segment
The last segment in a program is the end segment. When rea-
ching the end segment, output of the setpoint output last is con-
tinued.
Waiting and operator call
a
All segment types except end segment can be combined with ”Wait at the end
and operator call”.
If a segment with combination ”wait” was configured, the programmer goes to
stop mode at the segment end (run LED is off). Now, the programmer can be re-
started by pressing the start/stop key (>3s), via interface or digital input.
1 Segmenttype = time
2 Segmenttype = hold
3 Segmenttype = time and wait
4 Segmenttype = time
