Sequence Mode is activated setting parameter “
SMS
” in submenu “control” 3.1.6.1 at page 39 to
ON
.
Wheighing sequence starts at the rising edge of Start signal; SP1, SP2, SP3 turn on.
In Sequence Mode the Over, Go and Under comparison is always done when the “
Complete output
” is
ON
and Judging Count “
JC
” 3.1.8.2 at page 44 is not set to “
0
“.
The weighing value compared with Final, Over and Under (“
FOU-CMD
”) can be Gross or Net, selected at
3.1.7.2 at page 41.
In this case parameter is set to “
1
“: compare with net weight”. In this case, Net weight is set to zero at
“start”.
When setting “
FOU-CMD
” to “
0
“: compare with gross weight”, then gross weight is set to zero at “start”.
Setting of parameter “
OUC-MD
” in menu 3.1.7.4 at page 42 has no affect! Internal treatment is like set to
“
3
”.
The weighing value compared at Near Zero (”
NZ
”) can be Gross or Net, selected at 3.1.7.1 at page 41.
In this case parameter is set to “
1
“: compare with net weight”.
Conditions:
- When weighing value
≤ set value of Near Zero, the Near Zero output turns on.
- When weighing value ≥ Final – Set Point1, the SP1 output signal turns off.
- When weighing value ≥ Final – Set Point2, the SP2 output signal turns off.
- When weighing value ≥ Final – CPS, the CPS output signal turns off.
- When weighing value ≤ Final – Under, the Under output signal turns on.
- When weighing value ≥ Final + Over, the Over output signal turns on.
- When Final – Under ≤ weighing value ≤ Final + Over, the Go output signal turns on.
Timers:
t1: Comparison Iinhibited Time “CITI” – set in 3.1.7.6 at page 42
t2: Judging Time “JTI” – set in 3.1.7.7 at page 42
t3: Complete Output Time – set in 3.1.7.8 at page 43
