The Model 214D-1 Batch Controller accepts pulse or frequency flowsignals and automatically controls the batching of fluids via a one or two stage control valve.The instrument is extremely flexible and easy to operate, with a fourkey front panel operation that enables the batch quantity to be set and batches to be started or stopped.This manual covers the Model 214D-1 which accepts most frequencyand pulse signals, including mV outputs from turbine flowmeters, and 2 wire proximity switch outputs. It also allows all four front panel switches to be remotely connected via the rear panel terminal...

The Model 214D-1 uses a low power CMOS microprocessor toperform all control functions and calculations.The instrument is fully configurable with all operating parameters andcalculation constants user settable. (See Section 5 entitled "Configuration" for information on configuring.) All parameters and constants are stored in a non-volatile memory which retains datawithout battery backup for a minimum of 10 years.A block diagram of the instrument is shown below. >

The four key operation makes the operation of the Batch Controllervery easy. > The batch quantity is set as follows: Switch ActionDisplayComments Press BATCH SETBatch"Batch" is displayed for one secondfollowed by the batch quantity last entered. The Batch Set LED lights. " 1 " 2345The most significant digit flashesindicating that it can be changed.Press " 2 " 2345Pressing the DISPLAY key willincrement the digit. The up arrow on theDISPLAY key indicates to increment digit.Press 2 " 2 " 345Pressing the RUN key will change digitand enable the next digit to be incremented. The right arrow on...

To start the process the RUN key is pressed. The Run LED will lightand the instrument will begin to totalize from zero or, if programmed tocount down, the display will decrement from the batch quantity.The batcher has two control relays which are energized and de-energized as described in Section 3.2. > The process can be stopped at any time by pressing the STOP key.Once the process has been interrupted in this way, it can be continued by pressing the RUN key or the process can be aborted and the instrument reset by pressing the STOP key a second time.When the process is interrupted, the...

8Operation HP289 Accumulated Total On the next press of the DISPLAY key, the display shows ACCfor one second followed by the accumulated total. The Accumulated Total cannot be reset during normal operation. > To prevent accidental entry of large batch quantities, a maximum batchlimit can be set during configuration. The operator is then prevented from entering a batch quantity which exceeds this predetermined value. >

The Batch Control functions can be configured to operate in one of twoways.1.At the end of the batch, the STOP key must be pressed to resetthe Batch Total. (This must be done before another batch can be started.) >

10Operation HP289 2.If Automatic Reset is configured on, a new batch iscommenced each time the RUN key is pressed. The Batch Controller can be configured to either count up from zero oneach batch or to count down from the preset batch quantity. >

The two control relays can be set up to control a single valve or a dualvalve with slow-stop and/or slow-start. Alternatively, the second relaycan be used to control a pump.The relay operation is shown on the previous two pages. A time delay between the Batch Start and the time when Relay 2energizes can be set to provide a soft start up. The delay can range from 0 (no delay) to 79 minutes and 59 seconds.A Prestop quantity (i.e., the quantity to the end of the batch) can alsobe set to provide a slowdown of flow at the end of the batch, thereby enabling precise quantities to be batched.The...
