5600 Batch Controller
9. 5600 Operation Modes
This section gives a detailed description of the 5600's simple and advanced operation modes (sec. 14) and how they affect the batch
contact, End of batch/totalizer output, option contact, and current output.
9.1 Simple Operation Mode
• Batch Contact (sec. 4): In simple mode, the batch contact is dedicated for on/off control. It is energized at the start of a batch and
de-energized at the end of a batch. It also de-energizes when STOP is selected from the front keypad or initiated by a remote contact
closure to the rear STOP terminals (sec. 5). A RESUME command can also be initiated by either method to complete the batch. The
front panel batch indicator turns on when the batch contact is energized.
• Counter/End of Batch Pulse Output (sec. 6):
In simple mode, the output is configured as a counter pulse output. The output
emits a
130 millisecond pulse for each engineering (total) unit measured. The output is a open collector type which requires an external pull up
resistor and power supply for external counter use (sec. 6).
• Option Contact - Missing Signal Alarm (sec. 7B):
This function provides alarm capability if flow is not
detected in 30 seconds after a batch cycle starts. If the flow sensor signal is missing, the option contact
energizes and the front panel contact indicator turns on, signaling the missing sensor signal. The batch
contact also
de-energizes, closing the flow control valve and stopping the batch. The alarm condition will remain until
the front panel ENTER key is pressed or a remote contact closure is made to the rear STOP terminal (sec.
5).
• Current Output - Batch Completion (sec. 8A):
This function is offered in the simple or advanced
operation mode. The output is a linear increase from 4 mA at batch start to 20 mA at batch end.
9.2 Advanced Operation Mode
• Batch Contact (sec. 4):
The batch contact is dedicated for on/off control and is either manually or automatically
compensated for batch overrun. Manual overrun compensation allows the operator to compensate for valve closure
time in a batching system. The operator is prompted to enter a batch volume that de-energizes the batch contact
early, compensating for valve closing time and eliminating batch overrun. Automatic overrun compensation counts sensor pulses
during the batch cycle, and any excess pulses after the batch stops. The instrument calculates the estimated batch overrun based on
the additional sensor pulses, then automatically reduces the next batch size for the next batch. During the next batch cycle, the batch
contact de-energizes early, thus closing the flow control valve early and eliminating batch overrun.
