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 de­activated 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.

Sensor Connection

The flow meter sensor is connected using the MS style connector located on the right side of the
enclosure. If a flowmeter cable was not supplied, follow the sensor connector diagram for cable
wiring instructions. Shielded cable is required! Do not connect the shield at the sensor end!

Sensor Connector Detail (5-pin on current units)

Pin A => Sensor Supply (isolated), approx. 18 VDC

Pin B => Sensor Common (isolated)
Pin C => Signal Input
Pin D => NOT USED

Pin E => Shield Connection (to Earth Ground )

Using a ΑSinking≅ Sensor

The LLC-E-BA accepts an Αactive≅ or Αsourcing≅ sensor output as standard. For sensors providing
an Αopen collector≅ or Αsinking≅ output, a pull-up resistor is required for operation as shown in the
LLC Input Circuit Detail below. The value of the pull-up resistor is selected so as to not exceed the
current rating of the pick-up output. Typical pull-up values range from 2.2KΩ to 5.1KΩ. The LLC-E­BA enclosure must be opened to install the pull-up resistor. The resistor is installed on the rear of the
LLC display module to terminals 1 and 3 on the upper connector. See Resistor Connection Detail
below for pull-up resistor installation.
