1. INTRODUCTION

The Model 414Q Batch Controller is designed for high accuracy flow

applications where it is required to batch liquids using a one or two stage valve

The Batch Controller includes such features as:

SINGLE or QUADRATURE pulse inputs.

NON-LINEARITY CORRECTION.

TICKET PRINTING or COMPUTER interface options.

The Model 414Q is ideally suited to custody transfer applications where high

accuracy and signal integrity is required.

The instrument is fully programmable, with all calculation constants set via the

front panel switches and stored permanently in a non-volatile memory.

This instrument conforms to the EMC-Directive of the Council of European

Communities 89/336/EEC and the following standards:

Generic Emission Standard EN 50081-1 Residential, Commercial & Light

Industry Environment.

Generic Emission Standard EN 50081-2 Industrial Environment.

Generic Immunity Standard EN 50082-1 Residential, Commercial & Light

Industry Environment.

Generic Immunity Standard EN 50082-2 Industrial Environment.

In order to comply with these standards, the wiring instructions in Section 7.1

must be followed.

3. OPERATION

The Model 414Q uses a low power CMOS microprocessor to perform all control

functions and calculations.

The instrument is fully programmable with all operating parameters and

calculation constants user programmable. (See Section 5 entitled "Calibration"

for information on programming.) All parameters and constants are stored in a

non-volatile memory which retains data without battery backup for a minimum of

10 years.

A block diagram of the instrument is shown below.

A DIL switch on the rear panel enables the frequency input circuit to be set to

interface with a wide range of flowmeters, including turbine flowmeters and

flowmeters with Namur type sensors.

3.1 FRONT PANEL OPERATION

The four key operation of the Batch Controller is straight forward.

SETTING THE BATCH QUANTITY

The Batch quantity is programmed as follows:

Switch Action Display Comments

Press BATCH SET Batch "Batch" is displayed for one second

followed by the batch quantity last

entered. The Batch Set LED lights.

"1"2345 The most significant digit flashes

indicating that it can be changed.

Press "2"2345 Pressing the DISPLAY key will

increment the digit. The up arrow on

the Display key indicates to increment

digit.

Press 2 "2"345 Pressing the RUN key will change digit

and enables the next digit to be

incremented. The right arrow on the

RUN key indicates to change digit.

Press BATCH SET Set Once the desired number is entered,

press the BATCH SET key to return to

the Run mode. The Batch Set LED will

extinguish.

Once programmed, the Batch quantity will be retained in the non-volatile

memory and will not alter until changed by the user.
