DR4300 Circular Chart Recorder
DR4300 Circular Chart Recorder Product Manual 4/00xii
1.1 Introduction
Function
The DR4300 recorder is a one or two pen microprocessor-based circular chart recorder. The basic DR4301
(one pen) and DR4302 (two pen) recorders provide reliable, convenient pen-drawn analog traces on
preprinted 10 inch (250 mm) charts. Both the chart and the pens are driven by stepper motors controlled by
the microprocessor. Chart speed and range are configurable. The basic recorder is also available in CE
models DR4321 (one pen) and DR4322 (two pen).
In addition to generating pen-drawn chart traces, the DR4311 (one pen) and DR4312 (two pen) models
include a display and keypad. This option lets you display the real time value of the process variable for
each pen channel, as well as other values. The recorder with display and keypad is also available in CE
models DR4331 (one pen) and DR4332 (two pen).
Each pen channel has its own printed circuit assembly (PCA), allowing the channels to operate
independently.
Overview
1. Overview
CE conformity (Europe)
Indicated models of this product are in conformity with the protection requirements of the following
European Council Directives: 73/23/EEC, the Low Voltage Directive, and 89/336/EEC, the EMC
Directive. Conformity of this product with any other “CE Mark” Directive(s) shall not be assumed.
Deviation from the installation conditions specified in this manual, and the special conditions for CE
conformity in Section 2 of this manual, may invalidate this product’s conformity with the Low Voltage and
EMC Directives.
Analog inputs
The input for each pen channel can be one of any standard electrical signal: milliamp, millivolt, voltage,
RTD, or thermocouple. The input type and range are configurable. In the models having display and keypad
the range can be expanded and compressed to meet specific measurement needs. The display and keypad
also permit entry of input bias and filter values. (The input filter for the models without a display is fixed at
one second; their bias is zero.)
Digital inputs
Two digital inputs for each pen channel are available as an option. These inputs can be used to trigger the
switchover to a second control setpoint or a pre-configured constant output if an external event causes
contact closure (sets the digital input to ON). In addition, the digital inputs can be used to remotely reset the
optional totalizer or limit controller.
4/00 DR4300 Circular Chart Recorder Product Manual 1
DR4300 Circular Chart Recorder
Communications
The Modbus communication option permits configuration of the unit and monitoring of process variables
over a standard multi-drop serial communications link.
Relay outputs for control and alarms
The models with display and keypad are available with output relays, two for each pen channel. These
relays can be wired for Normally Open (NO) and Normally Closed (NC) terminals. ON-OFF control can be
performed using one relay (relay simplex control) or two relays (relay duplex control).
Any relay not used for control is available for alarming. Two alarm setpoints can be configured for each
alarm relay. An adjustable hysteresis of 0.0 % to 100.0 % is configurable for the alarm setpoint.
Analog output for control or retransmission
Depending on the model ordered, a 4 to 20 mA current output may be available for control or
retransmission of a process variable (“auxiliary output”).
Failsafe operation
The control function can operate in automatic or manual mode. In automatic the control function works to
maintain the process variable at the setpoint entered locally by the operator. During configuration a
“failsafe” value can be specified. This value is used as the output at power up and in case of input failure
during automatic operation. (When the unit goes to failsafe, the control function goes to manual mode.)
In manual mode the operator enters the output locally. If the recorder has gone to failsafe operation, the
operator will be able to change the output value from the failsafe value specified during configuration.
Timer and totalizer options
The recorder is available with timer and totalizer options. The timer can be started locally, remotely, or by
an alarm. The unit can be configured to display elapsed time or time remaining. At the end of the timeout
period Relay 2 is energized, and remains energized until the timer is reset. The totalizer can be reset locally
or remotely; its displayed value can be scaled.
Setpoint Programming Option
The recorder is available with a Setpoint Program option. This feature allows configuration of up to four
setpoint programs using a total of twenty-four ramp and soak segments. A setpoint and time is configured
for each segment. The program can be set up to include guaranteed soak segments. A plus/minus deviation
is configured for all soak segments. Whenever the plus/minus deviation is exceeded, soak timing is frozen.
Display and keypad
In addition to process variables, the display can show output, setpoint, and deviation real time values if the
recorder is equipped with optional outputs. The upper display uses four characters to display the input
value. The lower display shows other parameters using a two- or three-character label and four- or threedigit values. In addition, status and error messages flash on the lower display when necessary.
DR4300 Circular Chart Recorder Product Manual 4/002
The six keys are used to select the real time value to be displayed, and to select set up parameters and their
values during configuration. The display and keypad are behind the door, protecting them from dirt.
A supplementary external keypad is also available.
For more information about the operator interface on models having a display and keypad, see Subsection
4.2.
Configuration
The models without a display are configured with two switchbanks: one for configuration, the other for
input definition. Configuration is a simple matter of consulting a table in this manual; selecting the
appropriate combination of range, chart speed, engineering unit, and input type; then setting the switches as
shown in the table.
The display and keypad are used to configure models with these options. When the unit is in configuration
mode, set up parameters are displayed, and grouped by function. Designate site-specific values by selecting
them from a list of choices, or entering them as numeric values. The operator can be locked out from
making configuration changes.
The models with display also use a switchbank to define the type of input to be expected by the hardware.
Input parameters used by the software are configured using the display and keypad.
Overview
Self-diagnostics
All DR4300 recorders run self-diagnostics at power up and in the background during normal operation.
Problems are reported by error messages on the display when present. An LED in the models without a
display lights if the unit fails a self-diagnostic.
Construction
All DR4300 recorders are housed in a rugged molded case which can be panel-, pipe- or surface-mounted.
An acrylic-windowed, gasketed door protects internal components from harsh environments while allowing
easy access to the chart.

DR4300 Circular Chart Recorder
NOTE 1: PID control o ptions include current output plus two discrete outputs for alarms. If ON-OFF or
time-proportioned simplex control is used, only one discrete output is available for an alarm.
Time-proportioned duplex control requires the use of both outputs and therefore no relay outputs
are available for alarms on that pen channel. Accutune II tuning is a standard feature with PID
control options.
NOTE 2: Customer must supply the input actuation and range information for each input in the Free Form
section of the order to have the unit supplied with a Certificate of Calibration.
NOTE 3: Digital Inputs are only available when ordering outputs in Table I.
NOTE 4: 4 to 20 mA Retransmission Output includes two outputs per pen for alarms. You must specify
the type of alarm outputs required (i.e., Relay, SS Relay, Open Collector Outputs).
NOTE 5: On key numbers DR4301, DR4302, DR4321, and DR4322 the communication address is fixed;
the display assembly is required to change it. Only one DR4301 or DR4321 instrument, or only
one pen of a DR4302 or DR4322 can exist on the network, otherwise communication conflicts
will exist. Pen 1 is the default when communications is specified on these models.
NOTE 6: Recorder is supplied with one box of 30755820-001, 0 to 100 Even "starter" charts. For special
range configuration on the DR4301, DR4302, DR4321, or DR4322 Recorder, provide the Input
Type, Chart Range, Chart Speed, °C or °F, Engineering Units, Linear or Non-Linear Chart Type
when ordering.
For example: Pen 1: "J" Thermocouple, 0-375 °F, 7-Day Linear Chart
Pen 2: 4-20 mA, 0-1000, 7-Day Linear Chart
For configuration on Models DR4311, DR4312, DR4331, and DR4332, the customer must
supply completed "Configuration Worksheets" with order for units to be Factory configured.

2
threads are flush with the face of the bracket.
NOTE: Screw heads to be flange side of brackets.
Insert the case with gasket into the panel opening.
3
Install one left hand and one right hand bracket with 1/4 x 3/8 long bolts and lockwashers on
4
each side of the case.
NOTE: The notch on each bracket should be facing upward towards the top of the unit.
Do not tighten the hex bolts at this time.
Install the remaining right hand bracket on the top with the 1/4 x 3/4 long bolt and lockwasher.
5
Do not tighten the bolt at this time.
Place a screwdriver blade on the notch of each bracket and firmly tap so that each bracket
6
firmly mates the case with gasket to the panel.
NOTE: Keep brackets parallel to case. Tighten the three 1/4 hex bolts to hold the brackets in
place.
Start to tighten the #8-32 x 1/2 screws on the right side bracket. Alternate screws at opposite
7
ends until all four screws have a minimum of 10 lb-in of torque applied. Do the same to both
the left side and top brackets.
When completed all twelve screws should have a minimum of 10 lb-in of torque applied. This
assures the case and panel gasket are adequately sealed against the panel.
