400 Series
The 414 will interface to most flowmeters with versions available for pulse and analog inputs


414 Batch Controller

Overview

The 414 Batch Controller is suited to flow applications where precise measurement and control of batch quantities is required. Batch total, flow rate, accumulated total and preset value can all be displayed in engineering units on the large LCD display.

The 414 will interface to most flowmeters with versions available for pulse and analog inputs.

Batch Features

Automatic Overrun Compensation

Based on previous batches, the 414 will automatically compensate for any overrun which may be caused by slow closing valves.

Batch Limit

A maximum batch quantity can be programmed during set-up, so that the operator cannot enter a batch size that exceeds this limit.

If the flow signal cuts out midway through a batch, the output relays are de-energised, and an alarm signalled via an open collector output.

Remote Start/Stop

Remote push-button switches can be connected to the rear terminal strip, to start and stop batches.

Auto Restart

The 414 can be programmed to automatically restart the batch after a preset time delay.

Count Up/Down

The instrument can be programmed to count up from zero, or to count down from the batch quantity.

End of Batch

An End of Batch signal is provided via an open collector transistor output.

414 Batch Controller

Models Available

Model 414A

Analog input version with both linear and square law input relationships.

Model 414B

Frequency input version that will accept pulse and open collector inputs from opto-sensors or Hall effect devices.

Model 414D

Frequency input version with an input conditioning card capable of accepting mV signals from coils, 2-wire proximity sensors, reed switch inputs and most other pulse type signals.

Model 414H

For applications where batches are very short (<15 seconds) the 414H features a response time of less than 20ms.

The input is identical to the 414D but the scaling factor is limited to 4000 and the input frequency range is limited to 8kHz.

Model 414Q

Quadrature input version where the flowmeter produces two pulse or square wave signals 90° out of phase. Through the phasing of signals, forward and reverse flow can be detected.

Model 414LA

4-20mA temperature input version with temperature correction for general chemicals, petroleums to API tables and LPG (see separate data sheet).

Model 414LR

RTD temperature input version with temperature correction for general chemicals, petroleums to API tables and LPG (see separate data sheet)

Operation

Four key switches on the front facia, enable the batch quantity to be set, and batch operations to be started, stopped or reset.
To set a batch quantity, the BATCH SET key is pressed, and then the ▹ and ▵ keys can be used to change and increment digits. Once set, the key is again pressed to return to Run mode.

Keypad operations are straight forward and four LED’s indicate the operational status at all times.
In Run mode, the DISPLAY key can be used to display flow rate, batch and accumulated total.
The unique four key function simplifies operation, making the instrument suited to use by operators with minimal training.

Versatile performance options

The instrument will operate from 12 to 28V dc or from 100/110/220V ac mains. The facia is fully watertight to IP65 (Nema 4X) and is resistant to most chemicals.
The standard instrument is supplied as panel mount. Field enclosures and explosion proof enclosures are optionally available.

Computer/Printer Interface

An RS232 and RS422/485 option is available for interfacing to computers and printers. The interface allows the Batch Controller to be fully controlled from a computer via an ASCII protocol.

Software drivers are included for a number of printers and can print a ticket with time and date, a sequential delivery/batch number and the batch and accumulated totals. An optional header for the ticket can also be printed.

One or two stage valve control

Two output relays provide control for single or dual stage valve operation. The first relay will energise at the start of the batch, and de-energise when the batch is complete.

The second relay can be programmed to energise at a set time after the start, and to de-energise at a set quantity prior to completion of the batch. This feature enables a slow startup and slow shutdown of the flow.

The Batch Controller can also be programmed to count up from zero or down from the Batch quantity
