Introduction
Mounted in a pre-wired NEMA 12 industrial enclosure, the LLC-BA Batch Controller provides
accurate and repeatable batch control, stores up to nine different programmable batch quantities,
and is a rate, total or batch indicator.
The LLC-BA controls batch operation with relay contacts to initiate and stop the flow. Two
separate relay outputs allow the control of two solenoids with different flow rates providing a slow
stop/start of the flow. The LLC-BA activates the low flow solenoid on the START input and after
a programmed variable DELAY, the high flow solenoid is activated producing a combined high
flow rate. The high flow solenoid is deactivated before the batch amount has been reached by
means of the PRECUT variable reducing the flow for a slow stop. The low flow solenoid is de-
activated when the programmed batch amount is reached.
The LLC-BA compensates for a valve or fluid delay in the batch system with the Automatic Over-
run Compensation feature. The A.O.C. feature detects any overrun and the LLC-BA anticipates
and corrects for the delay on the next batch. This feature is always active and adapting
continuously to correct for long-term changes in valves and fluid characteristics.
