• Counter/End of Batch Pulse Output (sec. 6): In advanced mode, the output can be
configured as either a counter pulse output (sec. 9.1) or as an end of batch pulse
output. When configured as an end of batch pulse, the output emits a 500 millisecond pulse at the
completion of every batch. 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 - Two Stage Shutdown (sec. 7A):
This function is designed to prevent over filling or to minimize water hammer.
Both the batch and the option contact are energized when the batch starts. The option contact then de-energizes at a programmed batch percent-
age, forcing flow through a smaller bypass line to reduce the fill rate. After the entire batch is measured, the batch contact de-
energizes, completing the sequence. Front keypad and remote START, STOP, and RESUME
inputs (sec. 5) also control the option contact. The front panel contact indicator turns on when
the option contact is energized.
• Option Contact - Overrun Alarm (sec. 7B):
This function provides overrun alarm
capability for detecting a leaky or stuck valve. If the programmed batch overrun volume is measured after the batch
ends, the option contact is energized and the front panel contact indicator turns on, alarming
the operator that the flow shut off valve is leaking or stuck open. To cancel alarm, press the
ENTER key (or remote STOP switch) once. The overrun alarm will retrigger if the condition
persists.
• Option Contact - End of Batch Pulse (sec. 7C):
This function is designed to trigger an external batch counter or second 5600 Batch Controller at
the end of a batch. The option contact is energized for 500 milliseconds at the end of every batch cycle. An external power
supply switched through the option contact's common (COM) and normally open (NO) terminal provides a pulse for triggering
these devices.
• Option Contact - Missing Signal Alarm (sec. 7B):
The missing signal alarm represents a missing sensor signal after batch
start-up. An adjustable time delay entry (in seconds) is offered which specifies how long the instrument will wait after batch
start-up before initiating the missing signal alarm. See simple operation mode (sec. 9.1) for alarm operation details.
• Option Contact On/Off (sec. 10.4H):
This function enables or disables the option contact and front panel option LED.
When the option contact is configured "Off", the option contact and front panel LED are disabled.
• Missing Signal Alarm On/Off (sec. 10.4H):
Missing signal alarm is always enabled (factory default sec. 9.1) even if the option contact is selected to be a different function.
This function is designed to completely disable the missing signal alarm, if desired. NOTE: If disabled, the batch contact is
NOT affected and will NOT signal the operator or stop the running batch if there is a problem.
• Current Output - Batch Completion (sec. 8A):
In advanced mode, the current output
functions identical to the simple operation mode. See the simple operation mode explanation
above.
• Current Output - Valve Control (sec. 8B):
This function is designed for use with a George Fischer electric
actuator with PE 22P positioner for preventing overflow or minimizing water hammer. When a batch starts, the
current output is held at 20 mA, forcing the PE 22P positioner to the full open valve position. Near batch end, the output gradually ramps downward
to slow the flowrate, then drops to 4 mA closing the valve and ending the batch. Front keypad and remote START, STOP, and
RESUME inputs also control the output (sec. 5). A STOP command any time during a batch
sequence will force the output to 4 mA and close the PE 22P positioner. (Note: for optimum
performance, the batch process should last at least 1 minute!)
• Current Output - End of Batch (sec. 8C):
This function is designed to trigger a second 5600 batch controller's
remote START input for a second batching stage. When the batch starts, the current output remains at 0 mA until the end of the batch, then jumps to
20 mA for 500 milliseconds. The 500 millisecond current pulse triggers the second 5600's remote START terminal to start the second batch stage.
