The above phenomenon occurs because the detection and input switches are of NC type. If they are of NO type,
the front indicator lamps of IN20 and IN21 will not light up, and there will be no limit alarm for the tool
regulator, until the input signal is detected and it is beyond the tool regulator limit.
In the case both the detection and limit switches are of NC type, we need to invert the active levels of the input
detecting points IN20 and IN21. Parameter->Port-> 047. Input detection active level 00-31--------Change the
input detection active level of IN20 and IN21 in the input mode. After changing the input detection level as
shown below, press and hold the “EOB” button until the pop-up dialog box disappears. Then, press the Reset
button, the tool regulator alarm will disappears, and the indicator lamps in front of IN20 and IN21 will be off.
