11.CONTROL I/O (EXTERNAL SIGNAL)
78
11-5. External Output Signal
11-5-1. Near zero [pin 17]
When weight value
≦
Near Zero set value, the Near Zero output turns ON.
The weight value could be Gross, Net, Absolute Gross, Net or Comparison OFF that are selected in
Near Zero Comparison of the Comparison Mode.
11-5-2. Lower limit, Upper limit [pin 43, 44]
The Lower Limit output turns on when weight value < Lower Limit set value.
The Upper Limit output turns on when weight value > Upper Limit set value.
The weight value here could be Gross or Net that are selected in U/L Limit Comparison;
Also, could select Comparison regularly, or Comparing when external judging input is on (EXT.
JUDGING ON) in the U/L Limit Comp. Mode of the Comparison Mode.
* When Total is selected in U/L Limit Comparison, the setting value of Upper/Lower Limit is increased
by ten.
11-5-3. Stable [pin 45]
This output turns on when the weight value is stable.
* Refer to
on Page38 for details.
11-5-4. Weight error [pin 46]
This output turns on when the LOAD, -LOAD, OFL1, OFL2, OFL3 happen or ZALM turns ON.
11-5-5. Run or Total limit [pin 49]
The output turns on when F805AT-CK is ready to operate and external output is OFF in Total
Comparison.
The output turns on when external output is ON in Total Comparison and Total limit output is ON.
11-5-6. Under, Go, Over [pin 21 ~ 23]
When the COMPLETE output is ON, comparison is made and the corresponding signal turns ON.
Each signal turns ON under the following conditions:
Under
Weight value < FINAL set value - UNDER set value
Over
Weight value > FINAL set value + OVER set value
Go
FINAL set value + OVER set value
≧
weight value
≧
FINAL set value - UNDER set value
The weight value depends on the setting of OVER/UNDER COMPARISON.
11-5-7. Complete [pin 24]
After data sampling, processing of average calculation is executed.
After processing of average calculation, the COMPLETE signal turns ON.
The time required for processing of average calculation is within 50msec.
