instruction of F5 in chapter 6. Selection 14, 15, 46, 47 are separately corresponding to the full
load and over load functions, and they have explained these inputting signals’ properties.
Users can use them according to the function.
Take the over load for example, if the user installs the over load switch at the beginning of
the rope of the machine room, use the N.C. point; If the main control bo
ard prepares to use
terminal X23 as over load inputting, it should set F5-23 as 46, and input the N.C. signal of the
over load switch to X23.
In this way, set F5-36 as 0.
7.7.3 Analog signal inputting mode:
There are two inputting passages of the analog signal in NICE 3000 system: CN6 of the car top
board (MCTC-CTB-A), CN9 of the main control board (MCTC-MCB-A).
If the pre-torque of NICE 3000 uses an
alog signal inputting, users can take the no load and
full load auto-tuning through the weighing auto-tuning function (F8-00, details refer to the
function instruction in chapter 6), among these, F8-06 is corresponding to no load sampling
point’s data, and F8-07 is corresponding to full load sampling point’s data. According to
these information and sampling of current analog weighing signal, NICE
3000 can judge the
car cage’s load condition. If it’s over 110% of full load, it indicates over load; if over 100%,
it indicates full load. One point should be paid attention is that the maximum range of the car
cage’s weighing analog signal’s sampling is 0~255. Therefore, if the sampling value of
110% car cage’s load is over this range, over load will never occur!
When in this way, experienced sta
ff is required to operate in order to avoid over load without
alarming!
If analog signal connected to the car top board, set F5-36=2; if it’s connected to the main
control board, set F5-36=3.
