214D Batch Controller

The Model 214D Batch Controller is designed for flow applications where the precise control of batch quantities is required. Batch Total, Accumulated Total and Preset values can all be displayed on the large LCD display.

For hazardous area applications, the 214Di is an intrinsically safe version with both ATEX approval, and CSA approval covering both the USA and Canada.

The 214D has an input conditioning circuit which will accept pulse or frequency flow signals generated by turbine,
positive displacement, paddlewheel or other flowmeters.

Configurable link positions enable the input circuit to be configured for the different signal types.

DC powered with battery backup

The 214D will operate from an external power source between 9 and 28 Volts and draws no more than 4mA.

Lithium batteries provide backup if the DC power is interrupted so that totals are not lost. The solenoids or sensors, however, may still require external power.

Solid state outputs provide control to solenoids and relays, and can sink up to 200mA.

Watertight field mounting enclosure

The 214D Rate Totaliser is housed in a rugged yet attractive IP67 (Nema 4X)  rated polycarbonate enclosure which is completely watertight. A special universal bracket, supplied as  standard, enables the instrument to be wall mounted. A 2″ pipe mounting bracket is also available as are bottom and rear mounting stems for mounting the 214D directly on  turbine flowmeters which have a 1″ NPT or BSP boss.

Fully user programmable

K-factor, decimal point positions, valve delays and signal timeouts are fully user programmable. The Signal Timeout feature, if programmed, will automatically stop the batch if the flow signal cuts out midway through a batch.

One or two stage  valve control

Two solid state relays are provided which can be set up to control a single or a two stage valve with slow stop and/or slow start. Alternatively, the second output can be used to control a pump.

The first output will energise at the start of the batch, and de-energise when the batch  is complete.

The second output can be programmed to energise at a delayed Start Time after the batch start (0 to 9 seconds delay), and to  de-energise at a Prestop quantity prior to completion of the batch. This feature enables a slow startup and slow shutdown of the flow.

Keyboard Operation

The unique 3 key operation of the 214D simplifies operation and enables batches to be controlled quickly and efficiently.

To enter a batch, the PRESET key is pressed and the ▲ and ► keys can be used to increment and change digits. Once set, the PRESET key is pressed again to return to the run mode.

In the run mode, the RUN and STOP keys are used to start, stop or to pause the batch.

Intrinsically Safe Installation

The 214Di is certified for use in hazardous areas with approved sensors and solenoids, according to the following approvals.

ATEX

Approval: DMT 03 ATEX E 097
Type of Protection: II 2G EEx ia IIB T3

CSA_US/C

Approval: 104840-5
Locations: Class 1, Groups C & D
Temperature: Maximum ambient of 60°

Flowmeters with Namur Proximity switches

Namur Proximity switches may be used but will require a separate barrier to power the Namur switch, as shown opposite.

Output and DC power

A barrier is required to provide DC power to the instrument and to power the IS solenoids or relays. One or two barriers may be used depending upon whether a one or two stage valve is used. Connection is as shown opposite.

Only certified intrinsically safe solenoids may be used for IS applications. Because these solenoids have a relatively small coil, they are usually only suitable for small line sizes and non-viscous products.

Generally, it is preferable to use a pneumatic system with the solenoid valves controlling air to a larger pneumatically controlled valve.
