Creating And Editing A Program - Lauda ECO Silver E 4 S Operation Manual

 A tolerance range which is too tight can however also cause undesired delays. In particular with exter-
nal control the range should not be chosen too tightly. In Segment 5 a larger tolerance has been en-
tered, so that the desired time of ten minutes is maintained even with settling action .
 Only flat (slow) ramps should be programmed where necessary with a tolerance range. Steep ramps
which lie close to the maximum possible heating or cooling rates of the thermostat may be severely de-
layed by a tolerance range that is too tight (here in Segment 2) .
Note:
No time specification is possible in the start segment (No. 1). The temperature of the first segment is attained as quickly as
possible in order to switch to segment 2 after reaching the set tolerance.

Creating and editing a program

In the following functions are explained below:
Creating and editing a program.

Insert or append a new segment.

 Delete a segment.
Note:
 New segments and be inserted and existing ones changed, even when a program is currently being executed. Fur-
thermore, except for the currently active segment, all segments can be deleted at any time.
 Changes to the currently running segment are possible. The segment is continued as though the change has been
valid since the start of the segment.
 If the new segment time is shorter than the already expired segment time,
then the program skips to the next segment.
 If a segment time is required > 999h:59 min, then this time must be spread over several consecutive segments.

The tolerance entry can have a large effect with external
bath control. The adjacent graph of the edited trace shows
the possible run-on of the actual temperature in the bath
vessel (continuous line) for the set-point temperature of the
programmer (highlighted in gray).
Note:
 The tolerance field facilitates exact conformance to
the dwell time at a specified temperature. The fol-
lowing segment is only processed when the actual
temperature reaches the tolerance band , so that
for example the ramp of segment 2 is only started
delayed by .
