Feed/ Discharge
(pin D9)
(level triggered)
Feed or Discharge is accessed by shorten(Discharge) or open (Feed) input D9 to COM.
“Fd-Con” (3.1.6.2 in submenu “control” at page 39 has to be “2”).
0: feeding
1: discharge
2: external control
During Dischrage mode, “Upper/ Lower Limits” has to be compared with Gross weight (“ULL-
CMD” 3.1.7.3 set to “0”) and “Final/Over/Under” has to be ompared with Net weight (“FOU-CMD”
3.1.7.2 set to “1”).
Note: “Discharge mode” is only available in Simple Comparison mode.
-
Start
(pin D10)
(edge triggered)
During “Sequence mode” shorten input D10 to COM will start sequence cycle.
-
Stop
(pin D11)
(edge triggered, level triggered)
During “Sequence mode” shorten input D11 to COM will stop sequence cycle or clears sequence
errors.
Refer to 6.6 “Sequence mode” at page 103 for more detail.
-
Start accumulation
(pin D16)
(edge triggered)
Accumulation is done when shorten input D16 to COM (OFF
Æ ON) and at rising edge of
“Complete output” signal. FOUC-MD (3.1.7.2 at page 41) has to be set to 0 (gross) or 1 (net).
“Func” + “3”: shows sum of accumulated weight
“Func” + “4”: shows counter of accumulated weight cycles
-
Clear accumulation
(pin D17)
(edge triggered)
Accumulation Counter and weight value is cleared when shorten input D17 to COM (OFF Æ ON)
for more than 3 seconds. For confirmation “del Acc” will be displayed.
-
User Function I
(pin D18)
(edge triggered)
This user defined function is activated when shorten input D18 to COM (OFF Æ ON).
Refer to 3.1.16.1 at page 64.
