Model PD6210 & PD6310 Batch Controllers Instruction Manual

Controller Operation
The PD6210 controller is capable of accepting current (0-20 mA,
4-20 mA) and voltage signals (0-5 V, 1-5 V, 0-10 V,
 10 V) and the
PD6310 accepts pulses (e.g. ±40mV to ± 8V), square wave (0-5, 0-12V,
or 0-24V), open collector NPN, PNP, TTL, or switch contact signals.
These signals are scaled to represent rate in engineering units from -
99999 to 999999. The pulse signals may be scaled with a K-factor to
represent a total for the batch, and grand total.
The default configuration displays batch total on the big display, and a
selection of rate, grand total, batch count, and preset on the little display.
When in pause or stop mode, the display will alternate the numeric value
with the run status in the big display and the display label for the little
display.
The controller has up to 4 relays on board (and 4 available with an ex-
ternal expansion module) which are used to either control the batch
process in single or multi-stage batch control, or as alarms that will be
active when the batch process is running. A 4-20 mA output option is
also available for retransmitting the process variable analog or pulse
signal.
Default Batch Control Operation
The following describes the operation of the three front panel operating
keys as programmed with default settings.
START Button
Press the START button to begin a new batch process.
BATCH Button
Press the Batch button to access the Preset (batch amount) menu.
Program the batch with the arrow keys, and confirm with the Enter
key.
STOP Button
Press the STOP key once during a batch to pause. Press the STOP
key while paused to stop and cancel the batch. Press the STOP key
while in stop/ready mode cycle lower display values of rate (or other
little display programmed parameter), grand total, batch count, and
preset.
!
Only STOP Button Enabled if a Batch is Running
During a batch process, only the pause/stop functions of
the STOP button will function. No other buttons will be
functional.
