Product Description 1.1
1.1.1 GENERAL
The instrument is a microprocessor based circular chart Recorder Controller capable of
measuring, displaying, recording and controlling from a variety of inputs. Applications include
temperature, level, pressure, flow and others. The instruments can be specified as either a
single or as a dual pen model.
Recording, control functions, alarm settings and other parameters are easily entered via the
keypad. All user's data can be protected from unauthorized changes by the Enable mode
security system, and is protected against memory loss, as a result of AC power outage, by
battery back-up.
The process sensor input for each terminal block is user configurable to directly connect to
either thermocouple, RTD, mVDC, VDC, or mADC inputs. Changes in input type can easily be
made by the user. Thermocouple and RTD linearization, as well as thermocouple cold
junction compensation, are performed automatically. The instrument process variable inputs
are isolated. An isolated 24 VDC regulated transmitter power supply can be provided in the
instrument for use with up to two 4 to 20 mADC process sensor transducers.
The instrument can be ordered to operate on either 115 VAC or 230 VAC power at 50/60 Hz.
The 230 VAC option includes a switch for selecting either 230 VAC or 115 VAC operation.
The instrument is housed in a structural foam enclosure suitable for panel or surface
mounting.

1.1.2 RECORDING
The instrument records the selected process variable on a 10-inch circular chart. One box of
standard charts is provided with each recorder. Charts are available in a wide selection of
ranges. Chart rotation speed is programmable from 0.1 to 999.9 hours per revolution in 0.1
hour increments. The instrument can be ordered with one or two pens. Pen 1 is red and Pen 2
is green. Pens are the disposable fiber-tip type.
1.1.3 DISPLAYS
Each instrument is provided with a digital display and status indicator for each pen provided
(See Figure 1-1, page 5). The display may be configured to display the Process Value,
Process Value and Setpoint, Deviation from Setpoint only, Deviation and Setpoint, or Setpoint
only. During configuration the display(s) is/are used to show the enabled modes of operation
and the parameter codes.
The display in the upper right corner is for Pen 1, the display in the lower right corner is for
Pen 2 (if provided). The display includes status indicators for Manual mode operation, Output
1, Output 2 , Alarm, degrees C, degrees F, engineering units, setpoint and minus sign. See
Figure 1-2 ( page 7).
Display resolution is programmable for 0.1 or 1 degree for thermocouple and RTD inputs, and
none, one, two or three decimal places for other input types.
1.1.4 CONTROL
The instrument can be provided with relay, solid state relay driver and milliamp DC outputs.
Instruments can be programmed for on-off, time proportioning, current proportioning or
position proportioning control depending upon the hardware present. Switching between the
Control mode and the Manual mode of operation is easily accomplished with a dedicated key
on the keypad. Switching is bumpless from the Control to the Manual mode, and while in
manual, manipulation of proportional outputs is possible. Each pen of a dual pen recording
controller is provided with its own AUTO/MANUAL key . Other standard control features
include proportional control output limits, setpoint limits, anti-reset windup and a unique
Automatic Transfer function. If configured, the Automatic Transfer function allows manual
control of the proportional output until the process reaches the setpoint at which time the
instrument will go into the Control (automatic) mode of operation.
1.1.5 ALARM
An Alarm indicator is standard for each pen. Two alarm functions are provided for each pen
and the alarm indicator will light if either alarm for that pen is on. Alarm settings are program-
mable. Alarm type may be selected as process direct or reverse (high or low), deviation from
setpoint direct or reverse, and deviation band open or closed within the band. Alarm outputs
can be provided by assigning any relay(s) Single Pole/Single Throw (SPST)or Solid State
Relay (SSR) driver to the respective alarm.
1.1.6 PROCESS VALUE RE-TRANSMISSION OUTPUT
If an instrument is specified with mADC current output(s), any of the outputs may be pro-
grammed to operate as a process value re-transmission output. The output is scaleable but
can not be used as a control output while assigned as a process value re-transmission output.

2.5.1 WIRING GUIDELINES
Electrical noise is a phenomenon typical of industrial environments. The following are guide-
lines that must be followed to minimize the effect of noise upon any instrumentation.
2.5.1.1 INSTALLATION CONSIDERATIONS
Listed below are some of the common sources of electrical noise in the industrial environ-
ment:
• Ignition Transformers
• Arc Welders
• Mechanical contact relay(s)
• Solenoids
Before using any instrument near the devices listed, the instructions below should be
followed:
1. If the instrument is to be mounted in the same panel as any of the listed devices,
separate them by the largest distance possible. For maximum electrical noise
reduction, the noise generating devices should be mounted in a separate
enclosure.
2. If possible, eliminate mechanical contact relay(s) and replace with solid state
relays. If a mechanical relay being powered by an instrument output device
cannot be replaced, a solid state relay can be interposed to isolate the instrument.

3. A separate isolation transformer to feed only instrumentation should be
considered. The transformer can isolate the instrument from noise found on the
AC power input.
4. If the instrument is being installed on existing equipment, the wiring in the area
should be checked to insure that good wiring practices have been followed.
2.5.1.2 AC POWER WIRING
Earth Ground
The instrument includes noise suppression components that require an earth ground
connection to function. To verify that a good earth ground is being attached, make a resis-
tance check from the instrument chassis to the nearest metal water pipe or proven earth
ground. This reading should not exceed 100 ohms. Each instrument should have a dedicated
earth ground. Do not chain link multiple instrument ground wires.
Neutral (For 115VAC)
It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a
voltmeter check between neutral and ground should be done. On the AC range, the reading
should not be more than 50 millivolts. If it is greater than this amount, the secondary of this
AC transformer supplying the instrument should be checked by an electrician. A proper
neutral will help ensure maximum performance from the instrument.
2.5.1.3 WIRE ISOLATION/SEGRATION
The instrument is designed to promote proper separation of the wiring groups that connect to
the instrument. The AC power wire terminals are located near the top of the instrument
boards. The analog signal terminals are located near the bottom of the instrument boards.
Maintain this separation of the wires to insure the best protection from electrical noise. If the
wires need to be run parallel with any other wiring type(s), maintain a minimum 6 inch space
between the wires. If wires must cross each other, do so at 90 degrees to minimize the
contact with each other and amount of cross talk. Cross talk is due to the EMF (Electro
Magnetic Flux) emitted by a wire as current passes through it.
2.5.1.4 USE OF SHIELDED CABLE
Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals
should be run with shielded cable. Connection lead length should be kept as short as pos-
sible, keeping the wires protected by the shielding. The shield should be grounded at one end
only. The preferred grounding location is at the sensor, transmitter or transducer.
2.5.1.5 NOISE SUPPRESSION AT THE SOURCE
Usually when good wiring practices are followed, no further noise protection is necessary.
Sometimes in severe environments, the amount of noise is so great that it has to be sup-
pressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppres-
sors" which mount on the noise source.
For those devices that do not have surge suppressors supplied, RC (resistance-capacitance)
networks and/or MOV (metal oxide varistors) may be added.
Inductive Coils - MOV's are recommended for transient suppression in inductive soils con-
nected in parallel and as close as possible to the coil. See Figure 2-2. Additional protection
may be provided by adding an RC network across the MOV.
Contacts - Arcing may occur across contacts when the contact opens and closes. This results
in electrical noise as well as damage to the contacts. Connecting a RC network properly
sized can eliminate this arc.
For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor
(1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel.
See Figure 2-3.

2.5.2 SENSOR PLACEMENT (THERMOCOUPLE OR RTD)
If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be
protected by the appropriate thermowell. The probe should be positioned to reflect true
process temperature:
In liquid media - the mose agitated area.
In air - the best circulated area.
THERMOCOUPLE LEAD RESISTANCE
Thermocouple lead length can affect instrument accuracy, since the size (gauge) and the
length of the wire affect lead resistance.
To determine the temperature error resulting from the lead length resistance, use the following
equation:
Terr = TLe * L where; TLe = value from appropriate Table
L = length of leadwire in thousands of feet.

RTD LEAD RESISTANCE
RTD lead length can affect instrument accuracy. Size (gauge) and length of the wire used
affects lead length resistance.
To determine the temperature error resulting from the lead length resistance, use the following
equation:
Terr = TLe * L where; TLe = value from Table 3 if 3 wire or Table 4 is 2 wire.
L = length of leadwire in thousands of feet.

Relay output(s), if provided in the instrument, may be assigned to control or alarm output
functions for Pen 1 and/or Pen 2 (if present). Current outputs may be assigned to control and
process value retransmission output for Pen 1 and/or Pen 2 (if present). The assignment of
the output function (s) are/is accomplished in the Program mode. SPST relay and/or SSR
driver output(s) is/are designated as Relay A through Relay H. SPST relays begin with Relay
A designation, then B, C, etc. SSR drivers begin with Relay H designation then G, F, etc.
except when 4 SSR drivers are required in conjunction with SPDT relays, then designation E
& F are not available. SSR driver designation becomes G, H, D, and C. SPDT relay output(s)
are designated as Relay A and Relay B only.
FIGURE 2-11A
SPST Relay Output
Connections are made to relays A through F as shown. Terminal connections are made using
TB6 (Relay/SSR Driver A, B), TB7 (Relay/SSR Driver C, D) and TB8 (Relay/SSR Driver E, F).

Current Output
Connections are made to current outputs A thruough D as shown. Each current output is
programmable as either 4 to 20 mADC or 0 to 20 mADC. Each output must be assigned to the
desired function in the Program mode. Terminal connections are made using TB10 through
TB13 for current output A through D respectively. Connect positive lead (+) to terminal 1 and
the negative lead (-) to terminal 2. Each current output will operate up to a 650 ohms
maximum load.

Configuration 3.1
After completing installation and wiring of the instrument the configuration (set up) procedures
must be performed to prepare the instrument for operation on the intended application. The
procedures include selecting specific parameters, entering data and possible jumper position-
ing. Once properly configured the instrument will retain the user selections in memory so this
procedure need not be repeated unless required by changes in the application.
Parameter selections and data entry are made via the front keypad. To ease configuration
and operation, user entered data has been divided up into several sections referred to as
modes. Each mode contains a different type of data or may be used for specific operating
functions. For two pen instruments, some modes are common to both pens. These modes are
as follows:

Associated with each mode is a series of unique displays that are accessed via the front
keypad.
Prior to first time operation of the instrument, the configuration procedures for the Program
and Tune modes must be performed as applicable. Calibration and Test modes are not used
as part of the instrument configuration or operation. These are used for service and mainte-
nance functions and are discussed in Section 5.4 & 5.5 of this manual (page 46 - 54).
