BC7
BATCH CONTROLLER 
The BC7 will
automatically deliver a preset quantity of liquid and show you the flow rate
and batch quantity.  Quick and easy to set up Just press the start
button Large easy to read displays Preset to your requirements
Automatically compensates for errors Save time, reduce waste and costs
Improve product quality No flow alarm Safely shuts down if your flow is
interrupted Works with most flowmeters
Application
This instrument has a huge range of uses, from container
filling to tanker loading.You can use it to deliver any preset quantity of
liquid accurately and reliably
Operation To start a
batch you just press the run button. One display will show you the batch count
whilst the other can be set to show either the flowrate or the preset batch
quantity. You can use the BC7 in two ways. 1 : Single relay operation.
The run button operates a relay to control a valve or pump, which is
automatically shut off at the end of the batch. 2 : Double relay operation
where 2 relays can be used independantly to control valves and pumps for slow
start and slow stop applications. Two LEDs show you when either of
the two relays are energised. The signal can be used for
a local display, remote display or converted for transmission to a separate
control system. Apollo have a range of instruments to suit all your
requirements.
Installation and Setup
The displays can be set for any units e.g. litres or
gallons. The setup is easy using the keypad and a beep is sounded with all
keystrokes. The BC7 can be supplied preconfigured for your application.
Operator access to the setup menu can be inhibited.
Features
Overrun compensation: The controller can
automatically compensate for errors caused by slow acting valves and deliver
exactly the volume you want. No flow alarm: If there is a problem
and the signal from the flowmeter stops an alarm will be given and the batch
will be stopped. Linearisation: The accuracy of your system can be
improved by programming any flowmeter errors into the BC7. There is a non
resettable total to allow you to monitor long term usage.
Construction
The Batch Controller is in a standard 1/4 DIN format to
mount in a panel. The front keypad is a sealed unit which provides you with
a splash proof seal that is resistant to most chemicals.

Front Panel Controls:
Run Activates the relays to
start the batch. Stop If pressed during batching the process
will be interrupted. The batch can then be continued by pressing the RUN
key or the sequence can be aborted by pressing the RESET
key. Reset The instrument batch quantity is reset.
Batch Set Allows an operator to change the preset quantity.
LED Status lights: Relay 1: The red relay 1 LED lights when relay 1 is
energised Relay 2: The red relay 2 LED lights when relay 2 is energised
Alarm: The alarm LED lights when a no flow alarm condition has been
detected.The Batch Controller is in a standard 1/4 DIN format to mount in a
panel. The front keypad is a sealed unit which provides you with a splash
proof seal that is resistant to most chemicals. To view the
