7.6 Ready for Batch Operation (optional)
WARNING: OPERATING TRANSMITTER WITHOUT HOUSING IN PLACE EXPOSES
ELECTRICAL HAZARDS THAT CAN CAUSE PROPERTY DAMAGE, INJURY OR
DEATH.
The Datamate 2200 transmitter with optional keypad and LCD is a full featured two-stage
batch controller. For accurate and repeatable batching, batch size should be large enough
to allow the flow meter to run one (1) minute for each batch. If proper programming
(Section 9) of the transmitter has been completed, the following procedures will allow you
to control a batch with the Datamate 2200.
7.6.1 Running a Batch
Monitor the progress of the batching process. Configure the display to show the
batch total.
You may see in the display the mass flow rate go to the fallback value. This
indicates that the measured density of the process liquid is above or below the
Low or High Density Cutoff respectively from that which is programmed in the
DENSITY menu. When this message is displayed, the meter may no longer
correctly measure flow and is assuming the fallback value as the flow rate. The
mass flow rate will return to the measured flow rate when the liquid density is
above or below the Low or High Density Cutoff respectively,
OR
when you disable
the Slug Flow Feature by selecting Zero.
7.6.2 Beginning a Batch
You have programmed as Section 9.6.1 the transmitter to either allow the
operator to change batch sizes before each batch (Run Mode Edit On), or run
repeated batches of the same size (Run Mode Edit Off). In the event of a sensor
error during a batch and the Batch Jog is enabled (YES), the transmitter can be
programmed to allow the operator to be able to override the effect of the sensor
error by depressing and holding down the start button, energizing the batch relays
until the sensor error has cleared. This feature can be turned off (Batch Jog NO).
If you programmed it to allow different size batches, press the remote START
button. The display will show you the Batch Cutoff Point. This is the batch size. If
you want to change the batch size, use the keypad to change the batch size, then
press ENTER. When you have entered the correct batch size, press START again
and the batch will begin. If you programmed the Datamate 2200 to run repeated
batches of the same size, press START to begin the batch.
7.6.3 Interrupting a Batch
In the event you have to interrupt a batch, press the STOP button on the keypad.
7.6.4 Restarting a Batch
To continue a batch after interrupting it, press the START button on the keypad.
7.6.5 Terminating a Batch
To terminate a batch after interrupting it, press the STOP button again.
