▣ The output/input is controlled as it is programmed in the indicator as the above timing chart in the
automatic program control Mode.
▣ The external input and output signal is like follows.
1. ZERO BAND OUTPUT:
It is ON when the GROSS weight is smaller than the zero band value(S.P1).
2. It is ON when the GROSS weight is bigger than the optional preliminary weight(S.P2).
It is OFF when the GROSS weight is smaller than the optional preliminary weight(S.P2).
- When the first output is OFF in the next batching operation, it is not ON although the START input is
OFF.
- Fill in the hopper by using the first output signal in the next batching operation.
3. Press the TARE key so that the display value(NET weight) could be 0kg.
4. START INPUT:
SECOND and THIRD output are ON when the START key is pressed after the delay time that is
specified in F53.
5. SECOND OUTPUT(Preliminary):
It is OFF when the NET weight is more than the set weight(Final(S.P4) - Preliminary(S.P3)).
6. THIRD OUTPUT(Final):
It is OFF when the NET weight is more than the computed weight(Final(S.P4) –Free fall(S.P5)).
7. HIGH LIMIT OUTPUT:
It is ON when the NET weight is more than the set weight(Final(S.P4) + High limit(S.P6)) after the third
output is OFF.
8. LOW LIMIT OUTPUT:
It is ON when the NET weight is smaller than the set weight(Final(S.P4) –Low limit(S.P7)) after the third
output is OFF.
9.FINISH OUTPUT:
When the NET weight is more than the Final value regardless of stability, it is ON after the delay time
that is specified in F54.
It is OFF after the delay time that is specified in F55 or within the Finish Signal OFF Range that is
specified in F56.
Ref. The Discharge Gate control signal could not be supplied in the NT-580A.
-Use the FINISH OUTPUT SIGNAL properly.
