<p>PURPOSE:To set an arbitrary operational range with easy operation by inputting the width of the operational range corresponding to a main set point and deviation between the center of the operational range and main set point in a controller, to which a signal such as a warning, etc., is outputted. CONSTITUTION:A range sandwiched by the range (oblique line part), to which the signal such as the warning, etc., is outputted, is the operational range of non-output, namely, the so-called negative operational range. By inputting the two valves of width Y of this negative operational range and a distance B from the center of the operational range to a main set point SP, the arbitrary operational range deviated from the main set point SP is set. Thus, the operational range, which is normally used frequently, with the set point SP as the center is easily set by inputting only the operational range width Y. By inputting the distance B to the main set point SP, the arbitrary operational range deviated from the main set point SP can be set as well and the degree of freedom can be increased for setting the warning.</p> |
