Product Description 1.1

1.1.1 GENERAL

The instrument is a microprocessor based circular chart recorder capable of measuring,
displaying, recording, and datalogging flow process variables. Three square root extraction
algorithms are available for use with a variety of transmitters and transducers, and four
algorithms are available for use with a variety of weirs and flumes.

Recording functions, alarm settings, and other parameters are easily entered via the front
keypad. All user data can be protected from unauthorized changes by the Enable mode
security system, and is protected against loss from AC power failure by battery back-up.

The process input for each pen is user configurable to directly connect to either mVDC, VDC,
or mADC inputs. Changes in input type are easily accomplished in the field. The unit's
process input is isolated from the rest of the unit. An isolated 24VDC regulated transmitter
power supply can be provided for use with two-wire mADC inputs.

The unit can be ordered for either 115VAC or 230VAC power at 50/60Hz. The 230VAC
option includes a switch for changing back and forth between 230VAC and 115VAC. The unit
is housed in a plastic enclosure suitable for panel or surface mounting.

1.1.2 RECORDING

The unit incorporates a 10 inch circular chart. One box of standard charts is provided with
each unit. 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 provided with one or two pens. Pen 1 is red and Pen 2 is green. Pens are of the
disposable fiber-tip type. Changes in pens, as well as charts, are quickly and easily accom­plished.

PAGE 5

A programmable chart/display filter is provided. This filter provides adjustable dampening of
the value displayed and recorded. The filter need not be used. (Configured in program mode
as "dFF," Display Filter Factor.)

2.5.1 WIRING GUIDELINES

Electrical noise is a phenomenon of the typical industrial environment. The following are
guidelines that must be followed to minimize the effect of noise upon any instrumentation.

2.5.1.1 INSTALLATION

Listed below are some of the common sources of electrical noise in the industrial environ­ment:
* Ignition Transformers
* Arc Welders
* Mechanical contact relays
* Solenoids
* Motors
Before using any instrument with devices listed previously, the instructions below should be
followed:

1. If the unit 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 relays and replace them with solid state relays. If
a mechanical relay being powered by the unit's output device cannot be replaced, you may
wish to use a solid state relay to isolate the instrument from this source of noise.

3. A separate isolation transformer which feeds only instrumentation should be considered. If
available, it can isolate many noise sources from the AC power input of the unit.

4. If the unit is being installed in an existing installation, a review of the wiring in the existing
area should be done.

2.5.1.2 AC POWER WIRING

5

4

2

Earth Ground
Each unit includes noise suppression components attached to the chassis that require an
earth ground connection. To verify that it is earth ground being attached, make a resistance
check from instrument chassis to the nearest metal water pipe or proven earth ground. This
reading should not exceed 100 ohms.

Neutral (For 115 VAC)
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

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 intrument 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 of the other lines, maintain a minimum 6 inch space
between the wires. If wires must cross each other, do so at 90 degrees. This will minimize the
contact with each other and reduces "cross talk". "Cross talk" is due to the EMF (Electro
Magnetic Flux) emitted by a wire as current passes through it. This EMF can be picked up by
other wires running in the same bundle or conduit.

PAGE 9

2.5.1.4 USE OF SHIELDED CABLE

Shielded cable helps eliminate pickup of noise the wires may be exposed to. Shielded cable
is a single or multi-pair of insulated wires with each wire or pair of wires surrounded by a wire
mesh or conductive foil and then covered with plastic insulation.

It is recommended that all analog signals be run with shielded cable. Connection lead length
should be kept as short as possible, thus keeping wires protected by the shielding. The shield
should be grounded at one end only, at the transmitter or transducer and the shield should be
stripped back before going inside the unit case .

Wiring Connections 2.6

All wiring connections are typically made to the unit with it installed. Connections should be
made at the terminal blocks, two 12 gauge wires maximum, using copper conductors only.
Terminal blocks are designated TB1 thru TB13. See Figure 2-2 for the terminal block
locations.

2.6.1 ELECTRICAL CONDUIT OPENINGS

The instrument case will have 3 or 4 conduit openings, depending upon the number of outputs
specified. To help minimize electrical noise that may adversely affect the operation of the
instrument, the wires indicated below should be routed through the conduit opening specified.
See Figure 2-1 (page 8) for conduit opening locations.

EC1 - AC power

How The Instrument Operates 3.1

3.1.1 OFF MODE

In the Off mode, the instrument alarm and preset function(s) is/are turned off, pulsed output(s)
are inactive and process retransmission signal(s) remain(s) active. The chart rotation can be
selected in the Program mode to stop or continue to rotate when the instrument is in the Off
mode. The pen remains active. The totalization function is inactive, but datalogging functions
continue.

The Off mode is entered by pressing and releasing the SCROLL key until the display reads
oFF, then pressing the DOWN key. If the instrument was displaying process value, the
display will read oFF, then the current process variable at two second intervals. If the
instrument was displaying total, the display will read oFF, then the total at two second
intervals. Entering the Off mode of a dual pen instrument will cause both pens to enter the Off
mode. The second pen display will be blank as the upper display reads oFF and displays the
value for the second pen at the same time as the upper display.

To exit the Off mode, depress the SCROLL key to proceed to any other mode, pressing the
DOWN key to enter that mode.

3.1.2 OPERATE MODE

In the Operate mode, the instrument alarm function(s), the preset function(s), the pulsed
output(s) and the process retransmission signal(s) are actively responding to the process
variable as selected in the Program, Alarm Set and Preset modes and the chart will be
rotating at the rate selected. The totalization function is active, as is the datalogging function.

3.1.2.1 TOTALIZATION

Totalization can be implemented on instruments provided with the totalization feature.
Totalization can be programmed on or off for each pen.

To initiate totalization, depress the SCROLL key until oPEr is displayed, then depress the
DOWN key.

To view the total, depress the DISPLAY SELECT key once with the PV value displayed. The
TOT light should be lit and the total for Pen 1 in the upper display and the total for Pen 2 in the
lower display.

Instruments with Totalization and second display will have the total displayed in the lower
display whenever the upper display is set to PV.

On two pen units only, a Combined Total is available. When activated in the Program mode
an additional step is added to the display choice sequence provided by the Display Select
Key.

If the totals are displayed and the DISPLAY SELECT key is depressed, the Combined Flow
Rate will appear in the top display with a C in the leftmost digit and the Combined Total will
appear in the bottom display. The PV and TOT indicators will be lit, respectively.

Note: When Combined Total is being used, it is required that the decimal position,
dPoS, and totalizer decimal position, tdP, in the Program mode, for both pens are the
same. When the totalizer for Pen 1 is reset, the combined total is also reset.

Upon sensor break, the Combined Total will increment at a indeterminate rate.

3.1.2.2 PULSED OUTPUTS

Pulsed output(s), one for each pen, can be implemented on instruments provided with the
totalization feature and a relay that is not assigned to any other function.

Pulsed output is selected in the Program mode. With a pulsed output select (PoS) equal to 1,
each time the Totalizer Display is incremented, the relay that is assigned, in the Program
mode, as a pulsed output will close for a duration of 50 milliseconds or 60 milliseconds based
on a 60 Hz or 50 Hz line frequency, respectively.

On two pen instruments, a Combined Pulse Output is available. This feature provides a
pulsed output as the Combined Total increases.

Note: Upon sensor break, the Combined Pulse Output will increment at a indetermi­nate rate.

3.1.2.3 PROCESS VALUE RETRANSMISSION

Process value retransmission can be implemented on instruments provided with at least one 4
to 20mA output.

Process value retransmission is selected in the Program mode. When selected, a current
output must be assigned and the process output must be scaled.

On two pen instruments, a Combined Flow Rate is available. When selected in the Program
mode, this feature provides a process value retransmission value equal to the combined flow
rate. The value is scaled using Pen 1 process output upper and lower parameters.

PAGE 15

3.1.2.4 DATA LOGGING

Data logging can be implemented on instruments provided with the data logging feature, and
it will store data for up to 28 days.

Each day, at the time specified by ttLd (time to log data), the following data will be logged:
date, minimum rate, its time, maximum rate, its time, daily total, and average rate. The daily
total is derived by substracting "yesterday's total" from the current total. The average rate is
derived from the daily total, taking into account the flow time base. After the data is logged,
"yesterday's total" will be set to the current total, and the minimum and maximum rates and
times are set to the current rate and time.

Logged data is accessed via a day number, with 1 through 7 corresponding to the current
week. At the beginning of each week (00:01 on day 1 - each Monday) the data is shifted
down one week, with the oldest weeks worth of data being discarded. All data for the current
week is zeroed, including the date for each day.

3.1.2.5 ENGINEERING UNITS PROCESSING ALGORITHM

In the Program mode, the parameter EuPA, Engineering Units Processing Algorithm specifies
how the engineering unit inputs are handled. This allows selection of the various algorithms
to convert the raw input in to the desired process value.

LINEAR CONVERSION - EuPA = 0
For those sensors/transmitters that provide an output directly proportional to flow, or other
applications where the instrument may be used with a linear input to output transformation.

SQUARE ROOT EXTRACTION - EuPA = 1
The square root extraction function applies to rate of flow measurments using differential
pressure sensors. Differential pressure transmitters typically generate a 4-20mADC signal
that represents differential pressure, not flow. The flow is a function of the square root of the
differential pressure.

2 STAGE SQUARE ROOT EXTRACTION - EuPA = 2
This approach is used to minimize the process value below a 4% input, since it is less
meaningful due to inaccuracy and repeatability problems. Below 4% a linear function is
applied.
(Continued on next page)

PAGE 16

3 STAGE SQUARE ROOT EXTRACTION - EuPA = 3
This approach is used to further minimize the process value below a 1% input, since it is even
less meaningful. Below 1% a low gain linear function is applied. Between 1% and 2.5% a
higher gain linear function is applied. Above 2.5% the square root function applies, as the
sensor begins to provide a reasonably accurate and repeatable output. Refer to the glossary
(page 53).

VARIABLE EXPONENT - EuPA = 4
Open channel flow is used in wastewater and other applications. For rectangular weirs, the
flow is proportional to the height/head to the 3/2 power. For triangular (or V notch) weirs, the
flow is proportional to the height/head to the 5/2 power. For Parshall flumes, the flow is
proportional to the height/head to approximately the 3/2 power. See Table 3-1. When
variable exponent is selected in the Program mode, Engineering Units Exponent, EuE, must
be set for the correct exponent value.

TABLE 3-1

The exponent for a number of common Parshall flumes are as follows:

1 - inch = 1.55
2 - inch = 1.55
3 - inch = 1.547
6 - inch = 1.58
9 - inch = 1.53
1 to 8 ft = 1.522w raised to the .023 power
10 to 50 ft = 1.6

w = throat width in feet

PIECEWISE LINEAR - EuPA = 5
For some applications, the relationship between the input and process value cannot be
specified by one of the available algorithms. For these instances, the relationship can be
approximated by a straight line relationship over portions of the span. Provided enough
pieces, this method will provide the required accuracy. When piecewise linear is selected, the
second set of Engineering Units parameters, Euu2 and EuL2 must be used to specify the

span of the input, and then iu1, iu2....iu20 and Pu1, Pu2.....Pu20 are the input and process

values for the respective points, in engineering units.
VARIABLE EXPONENT WITH CORRECTION - EuPA = 6

For some applications, the relationship between the input and process value can be basically
characterized as exponential, but not to within the accuracy desired. Use of the Piecewise
Linear algorithm may require a large number of points to provide the desired accuracy. By
using the piecewise linear method to provide a correction to the simple exponential, a high
degree of accuracy can be achieved. This is especially applicable to open channel flow using
Palmer-Bowlus flumes or H flumes. Consult factory for assitance, if needed, when using
variable exponent with correction.

SATURATED STEAM FLOW WITH PRESSURE CORRECTION - EuPA = 7
Only available with a 2 Pen unit. For saturated steam flow, accurate flow measurement is
dependent on pressure correction. By using the second pen to input and record pressure, the
pressure data is available to correct the flow value. The input is typically gauge pressure,
which is converted to absolute pressure by the instrument. Since the pressure may be in the
60 PSIG range, barometric pressure or elevation can induce an error. Therefore, the baro­metric pressure, bAro, needs to be set in the Alarm Set mode. If the input is absolute
pressure, bAro must be set ot zero.

3.1.2.6. TOTALIZER FACTOR

Scaling of the displayed total is possible, with the use of totalizer factor, tFAC. When used,
the displayed value is multiplied by a factor to obtain the actual total. See Table 3-2.

TABLE 3-2

tFAC = 0 Actual Total = Displayed Total Times 1
tFAC = -1 Actual Total = Displayed Total Times 10
tFAC = -2 Actual Total = Displayed Total Times 100
tFAC = -3 Actual Total = Displayed Total Times 1000
tFAC = -4 Actual Total = Displayed Total Times 10000
tFAC = 1 Actual Total = Displayed Total Times 0.1
tFAC = 2 Actual Total = Displayed Total Times 0.01
tFAC = 3 Actual Total = Displayed Total Times 0.001

Example
An application is measuring flow at a maximum rate of 6000 gallons per minute (6000 gpm).
The steady flow rate is 2000 gallons per minute (2000 pgm). Table 3-3 shows how, with
various settings in the Program mode, the process variable displayed and the total displayed
can be configured.

Configuration Introduction 4.1

After completing installation of the unit, the configuration procedures contained within this
section must be performed to prepare the unit for operation on the intended application. The
procedures include selecting specific parameters, entering data and possible jumper position­ing.

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 modes. Each mode
contains a different type of data or may be used for specific operating functions. For two pen
instruments, each mode is common to both pens. These modes are as follows:

Mode Display Code Function Description

Off oFF Operation Alarm Outputs off, Totalization off
Operation oPEr Operation Operation
Program Prog Configuration Configure operating parameters
Alarm Set ASEt Configuration Set alarm settings
Data logger dLS Configuration Adjust/set real time and log time

Setup
Data logger dLd Operation View logged data

Display
Preset PSA Operation Adjusts, sets preset values

Adjust
Test tESt Service Perform unit tests
Calibration CAL Service Perform unit calibration
Enable Enab Configuration Lockout or enable access to any

mode

Associated with each mode is a series of unique displays which are accessed via the front
keypad.

Prior to first time operation of the unit, the configuration procedures for the Program, Preset
Adjust, Data logger Setup, and Alarm Set modes must be performed as applicable.

Calibration and Test modes are not used as part of the unit configuration or operation. These
are used for service and maintenance functions and are discussed in detail in Section 5.6 of
this manual (page 40).

Shipped Configuration/Jumper
Positioning 4.2

Each instrument is factory shipped ready to accept a 4-20 mA process input on each speci­fied pen. All configuration parameters in each mode are set to default values. These defaults
are shown in tabular form under the description for each mode. Instrument AC power input is
as specified in the instrument model number and as shown on the ratings label. The 230VAC
option includes a switch for changing between 230VAC and 115VAC. If this feature is
provided, verify AC input and switch position before applying power to the instrument.

4.2.1 JUMPER POSITIONING

Jumpers are used in all units to provide a security lockout feature and to condition the process
input for each pen. All jumpers are typically of the three pin type and have two functions. All
jumpers are located on the instrument's Processor board. A board layout and jumper loca­tions are shown in Appendix A-1 (page 46). Check the actual jumper position in the unit to be
configured and verify the proper position for the intended application. If the current position is
not correct, make changes.

The process input jumpers JU4 and JU5 condition the hardware at a basic level.
Detailed input type selection is made in the Program mode configuration (page 26).

PAGE 19

Operation Summary 4.3

The configuration and operating modes, the method of moving from one mode to another, and
the basic parameter functions are described in each individual section . Data and parameter
entry is made by stepping through each mode and making an appropriate response or entry to
each step.

4.3.1 KEYPAD OPERATION

Refer to Figure 4-1 for the Keypad features. Use the SCROLL, UP and DOWN keys as
indicated to program and operate the intrument.

4.3.1.1 UP/DOWN CHANGE RATE

The Up and Down keys are used to adjust numerical values up or down respectively. The
rate at which a given value will change is dependent upon the length of time the key is kept
depressed, initially slow then increasingly faster.

4.3.2 CONFIGURATION DISPLAYS

Each pen specified is provided with its own 4 digit LED display (8 digits for totalization option).
These are used during configuration to display the parameter codes and values. The display
located in the upper right hand corner of the instrument is used to show the codes for Pen 1
and those that are common between Pens 1 and 2. The display in the lower right hand
corner is used to show the configuration codes for Pen 2 (if provided).

During normal operation, the display(s) are used to indicate process value(s) as selected in
the Program mode.

4.3.3 MODE SELECTION

If the instrument is either in the Off mode or the Operation mode, repeated pressing and
releasing of the SCROLL key will cause the instrument to display the code corresponding to
each mode that is enabled. To enter a mode, while the code is displayed, press the DOWN
key.

Entry into any mode, except the Operation and Enable modes, will cause the alarm(s) to turn
off and any process re-transmission value output(s) to be 0%.

Start Up Procedure 4.4

All configuration parameters are listed in Tables 4-1 through 4-3 (pages 25-30)
For a single pen instrument, parameters for each mode are displayed in the upper right

display. If the instrument being configured is a two pen, a sequence of applicable parameters
will be displayed in the Pen 2 display after Pen 1 parameters have been reviewed and
configured. After the Pen 2 parameters have been completed, parameters common to both
pens will be configured and displayed in the Pen 1 display.

The instrument is provided with a time out feature. If the instrument is in any mode and no
keypad activity takes place for 30 seconds, the instrument will time out and exit the mode
automatically. The display will be the code for the respective mode. If a mode code is
displayed for 5 seconds with no keypad activity, then the time out will cause the instrument to
proceed to either the Operation or Off mode, depending upon which operational state was in
use before entrance into the mode.

4.4.1 POWER UP PROCEDURE

Step 1
Verify that all electrical connections have been properly made before applying power to the
unit.

Step 2A - For instruments with software revision R2.99 and below
Upon power up, 7XXX will be displayed (X representing digits), then XXXX, then XXXX,
identifying the twelve digit model number as defined in the order matrix. Next, the EPROM
part number will be indicated P-XX. After the EPROM part number, the software revision level
will be displayed in the format rX.XX then tSt1, tSt2, and tSt3 will be displayed while Test 1
through 3 are executed automatically. Upon successful completion of these test, oPEr or oFF
will be displayed for about 3 seconds. The mode displayed will be the mode the instrument
was in when the power was turned off. During this time, the operator may select another
mode (Alarm Set, Enable) or non-operational mode (Test, Program, Cal).

Step 2B - For instruments with software revision r3.00 and above
Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show
the instrument is "alive". Then 7XXX will be displayed (X representing digits) then XXXX, then
XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the
EPROM part number will be indicated P-XX. After the EPROM part number, the software
revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power
Up, PAPU, in Program Mode is set to 0, pens go to "home" position at power up). During this
display, the decimal point after the "P" will blink to show the mode is active. Upon successful
completion of this routine, oPEr or oFF will be displayed for about 3 seconds. The mode
displayed will be mode that the instrument was in when the power was turned off. During this
time the operator may select another mode (Alarm Set, Enable) or non-operational mode
(Test, Program, Cal).

Step 3
If any error messages are displayed, refer to Section 5.6 (page 40) for a definition of these
error messages and the required action.

This parameter is adjustable from 1 to 20 which represents the number of scans of the
process variable that are averaged together before updating the displayed and recorded
value, and process value for retransmission. The factory default is 1=no filtering. Display
code dFF.

Flow Time Base

Specifies whether the displayed process value is in units/second, units/minute, units/hour or
units/day, such that the
units/second. Display code Ftb.

Hysteresis

The paramter is adjustable from 0 to 1000 units representing the width of the band (half above
and half below alarm setting). Factory default =10. Display code HyAo.

Input Correction

This parameter is adjustable from -1000 to 1000 units and is used as a method to compen­sate for a linear sensor error. Factory default is 0=no correction. Display code iCor.

flow rate can be converted to flow for totalization. Factory default = 1,

Platen

The flat surface in the instrument upon which the chart rotates.

Process Filter Factor

This parameter is adjustable from 1 to 20 which represents the number of scans per second
of the process variable that are averaged together before updating the process value used for
alarm, presets. The factory default value is 1=no filtering. Display code PFF.

Process Output

Allows retransmisstion of the process variable. Factory default is 0=not selected. Display
code Pout. If selected, a current output must be assigned to it and scaled using Process
Output upper and lower values.

Process Output Upper and Lower Values
(used in conjunction with process output)

These parameters specify the process value range over which the assigned current output will
decrease linearly from 100% to 0%. If the process value is greater than Pou the output will
be 100%. If the process value is less than PoL the output will be 0%. Factory default values
are 100.0 for the upper value and 0 for the lower value. Display codes Pou (upper) and PoL
(lower).

Process Rounding

This parameter is adjustable from 0 to 1000 units and is used to round the process value to
the nearest value specified. Intended for use where the engineering units span is large, to
reduce fluctuation. Factory default is 0=no rounding. Display code Prnd (e.g.Prnd=3,
Process Value=-6, -3, 0, 3, 6, 9 ...).

Square Root Extraction Algorithms
(Engineering Units Processing Algorithm)

This parameter chooses the equation for processing the input from a transmitter or
transducer.
EuPA = 0 - Linear is for inputs that are directly proportional to flow (no square root extraction
needed).
EuPA = 1 - Square Root, takes the square root of the input (pressure or differential pressure)
over the whole range of the input.
EuPA = 2 - Two Stage Square Root, takes the square root of the input when the input is
greater than 4% of input (20% of flow) and uses a linear relationship below 4% with a slope of

5.
EuPA = 3 - Three Stage Square Root, uses a linear relationship when input is less than 1%
with a slope of 1, a linear relationship between 1 and 2.5% with a slope of 10 and a square
root above 2.5%.
EuPA = 4 - Variable Exponent, when properly set , provides a means of accurately accommo­dating weirs and flumes.
EuPA = 5 - Piecewise Linear, provides the user with a means of inputing data from a non­linear sensor.
EuPA = 6 - Variable Exponent with correction, provides a means to use Palmer-Bowlus or H
flumes.
EuPA = 7 - Saturated Steam Flow with Pressure Correction.
Display code EuPA.

Totalizer Decimal Position

Specifies how the total, preset, and pulsed output values will be displayed. The factory
default=0, no decimal. Display code tdP.

PAGE 51

Totalizer Factor

Specifies how the total will be scaled, and as a result, the corresponding scaling of the preset
and pulsed output values. For totalizer factor = -4, -3, -2, -1, 0, 1, 2, or 3, the total will be
multiplied by .0001, .001, .01, .1, 1, 10, 100, or 1000 respectively. The factory default=0.
Display code tFAC.

Totalizer Low Flow Cutoff

Below the specified percent of full scale Process Value, the flow will not be added to the total.
The factory default = 1.0. Display code tLFC.
