FUNCTIONAL DESCRIPTION
1. The instrument is waiting for a batch start signal or
discharging start signal to be input.
2. When the batch start signal is input, the Batch Start wait timer starts.
3. When the Batch Start wait timer completes the set time;
• Full-flow, medium-flow, and dribble-flow output signals are turned on.
• The full-flow comparator inhibitor timer starts.
• The Batch monitoring timer starts.
4. When the weight reaches optional preliminary setting:
• The full-flow output is turned off.
• The medium-flow comparator inhibitor timer starts.
5. When the weight reaches preliminary' setting:
• The medium-flow output is turned off.
• The dribble-flow comparator inhibitor timer starts.
6. When the weight reaches free fall setting:
•The dribble-flow output is turned off.
• The judgment wait timer starts.
7. When the weight has stabilized after the judgment wait timer completes the set time;
• If automatic free fall compensation is being used, its calculation will be made.
• The Batch Finish output signal is turned on.
• If there is excess or shortage, a judgment result output signal (overlimit or underlimit) will be turned on.
• The Batch monitoring timer is reset.
• The net is accumulated automatically.
• The data is output from the interface set for auto print.
8. If the discharging start signal is input, the discharging start wait timer will start.
9. When the discharging start wait timer completes the set time;
• The discharging output signal is turned on.
• The discharging time monitor timer starts.
10. When the gross becomes lower than the zero range;
• The discharging valve close wait timer starts.
• The discharging time monitor timer is reset.
When an output condition is established, full flow,
medium flow, and dribble flow outputs are turned
off, but the other outputs are turned on.
Once the full flow, medium flow, and dribble flow
are turned off, they are not turned on until the next
start of loading.
Overlimit/underlimit is activated based on the net
upon batch finish. (May be changed to real-time
operation)
The zero range is a customer programmed control
mode operation.
For the connection of the thumbwheel switch
(16-digit mode) for setpoints, see 7-4.
