Accutune II™—Provides a new,
truly plug and play tuning
algorithm, which will, at the touch
of a button or through a digital
input, accurately identify and tune
any process including those with
deadtime and integrating
processes. This speeds up and
simplifies start-up plus allows
retuning at any setpoint.
Fuzzy Logic—This new feature
uses fuzzy logic to suppress
process variable overshoot due to
SP changes or externally induced
process disturbances. It operates
independently from Accutune
tuning. It does not change the PID
constants, but temporarily modifies
the internal controller response to
suppress overshoot. This allows
more aggressive tuning to co-exist
with smooth PV response. It can
be enabled or disabled depending
on the application or the control
criteria.
Individual Pen Options—Include
Totalization, a Timer function,
Digital Inputs, Auxiliary Output,
and Setpoint Programming
allowing the most flexibility to meet
the application need.
Quality/Support—The DR4300 is
backed up by a toll-free phone
number for technical assistance.
CE Mark—Conformity with
73/23/EEC, Low Voltage Directive
and 89/336/EEC, the EMC
Directive.
Options
Control Outputs—One or two
control outputs, PID-A, ON-OFF,
or PD with Manual Reset.

Relay Outputs—Optional outputs
rated at 2 Amps at 120/240 V or 10
Amps at 120/240 V. Minimum load
is 0.1 Amp.
Options, continued
Auxiliary Output—There is also
a 4 mA to 20 mA current output
available. If not used for control, it
can be used to retransmit a
process variable.
Digital Inputs—Two digital inputs
for each pen channel are
available. These inputs can be
used to trigger the switchover to a
second control setpoint or a preconfigured constant output if an
external event causes contact
closure. In addition, the digital
inputs can be used to remotely
reset the optional tolalizer or Limit
Controller or set up as a trace.
Alarm Selection—None, one, or
two relays to activate external
equipment when preset high/low
setpoints are reached.
Modbus
Allows you to network your
recorders to take advantage of
overall monitoring of the system
using an RS485 network.
Ramp Soak Programming—
Allows configuration of up to four
setpoint programs using a total of
twenty-four ramp and soak
segments. Run or Hold of
program is keyboard or remote
switch selectable.
Totalizer—Totalizes a variable,
such as a flow signal, on one or
both pens. Provides a 6-digit
digital display indication of the
totalized value with reset
capability. Totalizer allows the
units of the totalized value to be
different than the input units. A
low value cutoff value can also be
programmed for the totalizer.
Limit Control—This model
provides a latching relay that
activates whenever the PV goes
above (High Limit) or below (Low
Limit) a preset setpoint value. An
alarm message will be displayed
when the output is activated.

Digital Controller
The DR4300 Recorder is available
with an integral microprocessorbased single-loop PID controller
for each pen.
A variety of output types—current,
time proportional simplex or
duplex control, with
electromechanical relays, solid
state relays, or open collector
outputs are available.
Depending on the output type,
users can configure the control
action as ON-OFF, PID-A, or PD
with Manual reset.
The recorder’s display and keypad
allows the user to quickly view
what is happening with the
process and to easily make
changes, and with the door
keypad these changes can be
made without opening the
recorder door.

Outputs
The following output types are
available per the model selection
guide:
• Electromechanical Relay
• Solid State Relay
• Open Collector Output
Output Algorithms
The DR4300 is available with the
following output algorithms:
Relay Simplex—Provides On-Off
or Time Proportional (relay)
output. Electromechanical, solidstate or open collector outputs
are standard; 2 amp or 10 amp
externally mounted solid-state
relay outputs are optional. One
output available for alarm.
Relay Duplex (Heat/Cool)—
Depending on which control
algorithm you select, this duplex
output type can provide on-off
duplex or time proportional
duplex. The time proportional
duplex output provides independent PID tuning constants and
two time proportional outputs:
one for heat zone above the
50 % output, and one for cool
zone below 50 % output.
Alarming is not available
Current Simplex—Supplies
proportional direct current output
for final control elements that
require a 4 mA to 20 mA signal.
Both relay outputs are available
for alarm.
Current/Relay Duplex
(Relay = Heat)—Type of output
using one relay for time proportional output for Heat control if PV
is greater than SP and one 4 mA
to 20 mA signal for cooling
control if PV is less than SP.
Relay/Current Duplex
(Relay = Cool)— Type of output
using one 4 mA to 20 mA signal
for Heat control if PV is greater
than SP and one relay for time
proportional output for cooling
control if PV is less than SP.
Control Algorithm
Depending on the output algorithm
you select, the recorder can be
configured for the following control
algorithms:
On-Off—Whenever the controlled
variable deviates a predetermined
amount from the setpoint, the
recorder moves the final control
element to either of two extreme
positions. Hysteresis: 0 % to 100 %
PID-A—The recorder gives full
response to Setpoint and Process
Variable (PV) changes involving
Gain (Proportional), Reset
(Integral), and Rate (Derivative)
effects. There is a fixed relationship
between the value of the controlled
variable and the position of the final
control element. The adjustable
Gain, Rate, and Reset Time tuning
constants let you tailor the
recorder’s response to your
process requirements.
PD with Manual Reset—The
action is similar to the PID-A
algorithm except the reset (Integral)
value is entered as Manual Reset
tuning constant instead of Reset
Time. The manual reset value
eliminates offset by shifting the PD
calculated output upscale or
downscale to return the recorder
variable to the setpoint.
Microprocessor Controlled
Recording
Both the chart and the pen are
driven by stepper motors controlled
by the microprocessor for precise
operation. This allows for
configurable chart speeds without
the need to change motors or
gears. The microprocessor uses
the configured range selection and
input data to determine the proper
pen position and then accurately
positions the pen to the correct
chart position without the need for
slidewire feedback or drive cables.
This provides for accurate and
reliable data recording.
Operator
Interface/Configuration
Since microprocessor control
replaces the previous electromechanical recording
mechanisms, the configuration of
the recorder is determined
primarily by its software.
For the basic recorder the
configuration is easily set up by
selecting the pre-configured
range, actuation, and chart
speed.
An optional display, using English
language prompts, provides
additional flexibility to select other
chart ranges, input actuation,
control or alarm parameters,
chart speeds, plus other software
features.
An upper and lower display
allows the user to view the
process variable (PV) and, by key
selection, the control setpoint,
control output, deviation from
setpoint, totalizer, Setpoint
Programming operation
information, time remaining or
elapsed time on the timer and the
status of Accutune, as desired.
In the Setup mode, digital
displays are preempted by
prompts and values for entering
the configur-ation data. Indicators
light to show which input channel
PV is being displayed, which
output relay is active, the
selected temperature unit, and
the recorder’s mode of operation.
The configuration data and
display actions are selected using
an integral keypad.
An optional keypad on the door
allows changes without the need
to open the door of the recorder.
The display can also be set to
toggle between Input 1 and Input
2. The display can also be set to
blank (turn off) if the operator
does not want to see a displayed
value.

Input Processing
The input can be one of any
standard low-level electrical
signals which can be selected by
the user.
Ranges are either pre-configured
or, by using the display/keypad,
expanded and compressed within
the range limits to meet the
specific measurement needs.
Users can select upscale or
downscale break protection for
most actuations.
Input samples are taken at a rate
of once every 0.33 seconds. Each
input is isolated from the other to
insure that the signals do not affect
the other inputs.
A digital filter value of 1 second on
the basic recorder provides input
signal smoothing or with the
display, this can be changed from
0 seconds to 120 seconds of
filtering to match the application
need.
The basic recorder provides a
wide selection of linear and nonlinear inputs for the user to select
which one best meets the need.
By adding the display, a full range
of selections is available to the
user. The non-linear inputs can be
set so the microprocessor
linearizes the input, thus allowing
mixed input actuations for two pen
models to record the process
variable on a linear chart. This can
be bypassed by recording on a
non-linear chart.
Control Modes
The recorder can operate in the
following modes:
Manual Mode—when switched to
manual mode, the recorder holds
its output at the last value used
during automatic operation and
stops adjusting the output for
changes in process variable.
Local Automatic Mode—The
recorder uses the local setpoint
and automatically adjusts the
output to maintain the setpoint at
the desired value.
Diagnostics
Each DR4300 has built-in
diagnostics that check critical
recorder operations and provide
error detection or messages to
alert the user of potential faults.
This self test is run each time the
recorder is powered up.
In addition to this, a built-in step
pattern test can be run on
demand to insure proper pen and
chart drive motor operation; this
draws a special test pattern on
the chart thus providing a record
of the recorder’s proper
operation.
Construction
All DR4300 recorders are
manufactured with a rugged,
durable, molded case designed to
withstand most industrial
environments. This case and the
standard NEMA 3 door are
designed to protect the internal
electrical components from harsh
industrial environments. The
recorder comes standard with an
acrylic window.
Knockouts in the side and bottom
of the case accept conduit
connections for convenient wire
entry of power, inputs, and
outputs. Individual boards for each
input allow the user to easily
service each input separately, add
an additional input to a single pen
recorder and to avoid problems
with isolation of each signal.
The removable connectors also
allow for easier servicing without
having to disconnect the field
wiring.
