9.4 Information on programming different temperature transitions
• For the end value of the desired cycle, add an additional section (in the examples section 05 for set-
point ramp and section 08 for set-point step) with a section time of at least one second. Otherwise, the
program will stop one section too early because the program line is incomplete.
• If the tolerance minimum is set to e.g. -5 and the tolerance maximum to e.g. +5, the program will be
interrupted when the actual value deviates by 5 °C or more from the set-point value. During this pro-
gram interruption, the display reads AUTO HAND on the bottom right instead of AUTO (program oper-
ation). You can enter different values for tolerance maximum and minimum for each section. When the
temperature is situated within the entered tolerance limits, the program will continue automatically, and
the indication AUTOHAND will disappear.
Programming of tolerances can extend program duration.
Therefore, the duration of the program may be extended due to the programming of tolerances.
The number -1999 for the tolerance minimum means “-∞“ and the number 9999 for the tolerance max-
imum means “+ ∞“. Entry of these numbers will never lead to program interruption.
During the rapid transition phase, do NOT program any tolerance limits in order to permit the maximum
heating and cooling speed.
• The initial setting ∗∗∗∗.∗ of the fan speed corresponds to the maximal speed of 100 %.
Do reduce the fan speed rate ONLY if absolutely necessary for the essay. Usually, the
spatial exactitude of the temperature decreases with decreasing ventilation. Technical
data refers to a 100 % fan speed rate.
• Programming is conserved even in case of a power failure or after turning off the unit.
• The controller memory can store a maximum of 25 programs. Each program cannot exceed 100 sec-
tions. It is not possible to link programs. The total number of program sections of all programs is lim-
ited to a maximum of 500.
• When the program is finished, the controller changes to Idle Mode.
If you incidentally press the EXIT or AUTOMATIC button during program operation, the con-
troller will change to Idle Mode and thus will not adjust any more to the program set-points.
We recommend keyboard locking (option, chap. 14.3) during operation.
General note:
The controller MB1 displays more menu entries than those described in this manual. These are password
protected because they are relevant for service purpose only and the user must not modify them. Only
service authorized by BINDER can access these entries.
