Binder M 56 - Tolerance Ranges; Repeating One or Several Sections Within a Time Program

10.7.5 Tolerance ranges
For temperature, you can specify a tolerance range for each program section with different values for the
tolerance minimum and maximum. When the actual value exceeds the given threshold, the program is
interrupted. This is indicated on the display (see below). When the actual temperature is situated again
within the entered tolerance limits, the program automatically continues. Therefore, the duration of the pro-
gram may be extended due to the programming of tolerances.
Programming of tolerances may extend program duration.
An entry of “-99999” for the tolerance minimum means “minus infinite” and an entry of “999999” for the
tolerance maximum means “plus infinite”. Entry of these values will never lead to program interruption. The
entry of “0” for the tolerance minimum and/or maximum deactivates the respective tolerance function.
When requesting rapid value transitions, we recommend not programming tolerance values in order to
enable the maximum heating-up and cooling-down speed.

band.
• Select the field “Tolerance band min” and enter the desired lower tolerance band value. Setting range:
-99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
• Select the field “Tolerance band max” and enter the desired upper tolerance band value. Setting range:
-99999 to 99999. Confirm entry with Confirm icon. The controller returns to the section view.
If one of those actual values for which a tolerance range has been specified lies outside this program
tolerance range the whole program course is interrupted. During this program interruption time the controller
equilibrates to the set-points of the current section.
The screen header indicates “Program pause (tolerance band)”. The program runtime indication flashes
and does not proceed any further.
When the corresponding actual values is back within the entered program tolerance range, the program
continues automatically.
10.7.6 Repeating one or several sections within a time program
You can repeat several subsequent sections together. It is not possible to define the start section the same
time also as the target section, therefore you cannot repeat a single individual section.
Enter the desired number of repetitions in the field “Number of repetitions” and the number of the section
to start the repetition cycle with in the field “Start section for repetition” To have sections repeated infinitely,
enter the number of repetitions as “-1”.
The selected sections are repeated as many times as selected. Then the program continues.
