- Be sure to connect the unit’s FG terminal to the ground terminal of the lter, which is inserted in the power source,
and connect the ground terminal of the lter to the most stable grounding point with shortest length.

• The actual installation environments such as panel congurations, connected devices, connected wires, may affect

the protection level of this unit when it is integrated in a panel system. The user may have to review the CE require­ments in regard to the whole system and employ additional protective measures to ensure the CE conformity.

* Except desktop type

n SAFETY PRECAUTION

• This equipment is for use in general industrial environments, therefore may not be suitable for applications which

require higher level of safety (e.g. safety or accident prevention systems) or of reliability (e.g. vehicle control or com­bustion control systems).

• For safety, installation and maintenance of this equipment must be conducted by qualied personnel.

• Before you remove the module, turn off the power supply and input signal for safety.

• Do not use the 73VR21x in an environment where ammable gases are present. This may result in an explosion.

• Do not disassemble or modify the 73VR21x in any way. Doing so may result in a re or an electrical shock.

• Do not strike the panel of the 73VR21x with a hard, heavy or pointed object, or press the panel with excessive force.

Doing so may result in panel damage or injury.

• Do not block the 73VR21x’s ventilation openings or use it in areas where heat accumulates. Additionally, do not store

or use it under high-temperature conditions.

• Do not store or use the 73VR21x in locations subject to direct sunlight, or where excessive dust or dirt is present.

• The 73VR21x is a precision instrument. Do not store or use it where large shocks or excessive vibration can occur.

•Do not store or use the 73VR21x in environments subject to chemical evaporation (such as that of organic solvents),

or where there are chemicals and/or acids present in the air.

• Do not use paint thinner or organic solvents to clean the 73VR21x.

• Observe the environmental conditions when using the 73VR21x.

• Wait at least for 5 seconds before turning on the power supply after it has been turned off. The 73VR21x may not

start up if the time interval is less than 5 seconds.

n ENVIRONMENT

• Indoor use.

• The 73VR21x is designed to be mounted on a vertical panel. It is not suitable for a slanted or a horizontal panel surface.

• Environmental temperature must be within 0 to 50°C (32 to 122°F) with relative humidity within 30 to 85% RH in order

to ensure adequate life span and operation.

• Desktop type cannot be mounted on a panel surface.

• The handle and rubber feet cannot be detached from desktop type unit.

n GROUNDING

• Be sure to determine in advance the most stable grounding point in the environment and earth the 73VR21x’s FG

terminal and that of connected devices to it in order to protect the devices from dielectric breakdown.

• Grounding is also effective to eliminate noise that could cause errors in the 73VR21x’s operation.

n LCD PANEL

• The LCD panel’s liquid contains an irritant. If the panel is damaged and the liquid contacts your skin, rinse imme­diately the contact area with running water for at least 15 minutes. If the liquid gets in your eyes, rinse immediately
your eyes with running water for at least 15 minutes and consult a doctor.

• The following phenomena are LCD characteristics, and NOT a product defect:

- LCD screen may show uneven brightness depending upon displayed images or contrast settings.

- The LCD screen pixels may contain minute blank-and-white-colored spots.

- The color displayed on the LCD screen may appear different when seen from outside the specied viewing
angle.

- When the same image is displayed on the screen for a long time period, an afterimage may appear when the
image is changed. If this happens, turn off the 73VR21x and wait for a while before restarting it.

• To prevent an afterimage:

- Set the screensaver when you plan to display the same image for a long time period.

- Plan to change the screen image periodically so that the same image does not remain for the long time period.

n MINIMIZING NOISE INTERFERENCE TO ANALOG SIGNAL CABLES

• Despite the 73VR21x’s excellent ltering capabilities against normal mode noise interference to analog signal cables,

we recommend that you would conduct wiring to the product with the following points of caution, especially for low­level signals with thermocouple, mV and RTD measurements.

• The 73VR21x is capable of notch ltering the 50/60 Hz normal mode line noise. Select the operating mode to match

the line frequency.

• The A/D Conversion Mode is factory set to ‘Medium’ but is programmable to ‘Slow.’ In general, selecting the ‘Slow’

A/D conversion mode means the lower data conversion cycles, but the stronger noise ltering. Change this setting
according to your needs.

• Do not install cables (power supply and input) close to noise sources (relay drive cable, high frequency line, etc.).

• Do not bind these cables together with those in which noises are present. Do not install them in the same duct.

n MINIMIZING CHANNEL-TO-CHANNEL COMMON MODE NOISE

• The CMNR ratio between channels are as described in the product’s data sheet. Input types such as ±12V, ±6V,
±3V, ±1000mV are mostly safe from these interferences, however, the measuring accuracies for other input types

may be compromised by large common mode noise.

• As described in the data sheet, the DC/AC voltage across the C terminals of the presently-scanned channel and the

last scanned channel affects the measuring values.

• In order to obtain stable measuring results without noise interference, it is effective to minimize the common mode

noise between channels and between each channel to the ground terminal.

We recommend that C terminals of each channel be cross-wired and then connected to the ground terminal to ensure

the measurement of the highest accuracy.

• If such conguration is not possible, take special consideration to minimize the channel-to-channel common mode

noise and the potential against the ground terminal.

• Employ a thermocouple/RTD sheath of high insulation to prevent a leak current. Do not weld a thermocouple directly

to the surface of the measuring subject.

• Arranging channels so that a low-level signal channel is not located next to a high potential signal channel while

multiplexing these signals is also effective.

• The potential of the open terminal C against the ground terminal equals to that of the last scanned channel. If ch

2 and ch 3 are not connected, the accuracy of ch 4 measurement is affected by potential difference between the C
terminals of ch 1 and ch 4.

n STABILIZING COLD JUNCTION COMPENSATION

• Sudden ambient temperature change could increase the cold junction compensation error by the internal terminal

temperature sensor. Please take the following precautions to prevent it.

• Be sure to close the terminal cover when operating the 73VR21x.

• Stabilize the temperature around the terminal block. DO NOT expose the terminal block in the direct line of air ow

from air conditioners, cooling fans, or ventilation fans. Switching on and off the fans located close to the terminal
block affects the ambient temperature.

• Disposition of the terminals for odd-number channels is tend to be more favored in the CJC stability than those for

even-number channels.

• Resistor modules (model: REM3-250) can be connected to the 73VR21x to convert current inputs into voltage.

However, it is not recommended when TC inputs are mixed because the heat developed on and around the REM3
affects the cold junction compensation performance. We recommend that REM3 be connected on a separate terminal
board.

• Do not use wires of large diameter which has large heat dissipation. We recommend using the wires of 0.5 mm

2

(AWG 20) or thinner diameters not only for the thermocouple channels but for all other screw terminals.

n CONNECTING OTHER DEVICES IN PARALLEL

• Turn off the burnout function for thermocouple inputs.

• No parallel connection is permitted for RTD inputs.

n DO NOT APPLY OVERRANGE NORMAL MODE VOLTAGE

• Do not apply voltages exceeding ±20V to terminals B – C for ±3V, ±6V or ±12V ranges to prevent damage.

• For other ranges, do not apply voltages exceeding ±12V to the same terminals to prevent damage. Applying voltages
exceeding ±1.5V may affect the measuring accuracies of other channels.

n INTERNAL CLOCK

• The internal clock data is stored in memory powered by a backup battery while the 73VR21x is without external power

supply.

• The data will be reset to its default status when the battery is used up while the 73VR21x is left without power sup­ply for a long time period. The clock adjustment will be necessary once the power is restored. Please refer to the
73VR21x Users Manual for the procedure.

• Once the power is restored, the 73VR21x starts recharging the battery. It will be full in approximately in 36 to 48

hours.

n AND....

• We recommend use of an UPS (switching time: without delay, output: sine waveforms) to supply power backups.

• The module is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for

satisfying complete performance described in the data sheet.

5.1.4 DATA STORING FORM

Touching the current selection of the Data Storing Form shows selectable options at the bottom of the screen. Choose
among the following options.

Float Floating point 1 data size: 4 bytes

Decimal fraction: max. 4 decimal places (effective number of digits: 6 or 7)
Float is to be selected when you need to store data including decimal fractions. The
4-byte-long data is better in data precision but the total storable time in the CF Card
becomes shorter compared from Short Int.

Short int Short integer Integer data multiplied by 10. The 2-byte-long data is not as precise (one decimal

place) as Float type is, but the total storable time in the CF Card is longer.

WHICH FORM TO CHOOSE? -- EXAMPLE

If you have selected Short integer, and when an input range 1 – 5V is converted in an engineering unit range of 0 –
10, the actual converted values are: 0 at 1V input, 0.25 at 1.1V. In this case, the 73VR21x can store only one decimal
place, and ‘0.25’ is saved only as ‘0.2.’ Likewise, the input 1.15V is converted into 0.275 in the engineering unit range,
but is saved also as ‘0.2.’ 1.1V and 1.15V inputs make no difference in the short integer form.
Choose Float if you want to make difference between 1.1V and 1.15V.

WARNING !

When the data storing form setting is changed, new data stored in the same data le overwrite previously stored data.

5.1.5 DATA OVERWRITE

Eng. Range

Set up physical representation of the upper and lower input range values. This setting determines the momentary
value unit displayed on the digital displays while recording. For a temperature input, this setting is greyed out.

Eng. range Max. 6 digits including a decimal point and minus sign

Caution !

The maximum data range handled by the 73VR21x is from -1 x 10

10

to 1 x 1010. Engineering range

must be within these limits. Any input out of this range is handled as errors.

Plot position

Determines the display range on the chart when ‘Normal’ is selected at ‘Normal / Log.’ Log’s detailed setting including
the display range is conducted in the Exp. scale. The plot position setting is effective on the Trend view, the Bargraph
view and bargraphs on the Overview.
Set up the upper and lower display range values using the keypad. It is usually the same as the engineering unit
range, but is set to a different range when you want to enlarge a part of the range to view details.
‘e’ can be used to input an exponential value such as ‘1e9.’ Entering ‘e’ in any other way (e.g. ‘1ee’) will not be recog­nized as a numeral.

Plot position Max. 6 digits including a decimal and minus sign

For example, if you have a temperature input:

UNIT LOWER LIMIT UPPER LIMIT This is the most common setting. Eng. Range and Plot

Position values are the same. Scales are -270°C at the
left edge, 1370°C at the right edge of the chart.

Scaled Range °C -270 1370

Plotted Range °C -270 1370

UNIT LOWER LIMIT UPPER LIMIT This is used when you want to enlarge a particular sec-

tion of the Eng. Range. The chart is used only for a nar-

rower range of 1000°C, between 0°C at the left edge and
1000°C at the right edge, against the 1640°C full-scale.

Scaled Range °C -270 1370

Plotted Range °C 0 1000

The plot range of a particular channel can be reected on the scale bar (engineering unit scale). For example, if you

have a plot range of 0 (lower limit) to 1000 (upper limit), the scale bar shows 0, 100, 200 .... 900, 1000, the full-scale

range (0 to 1000) divided by ten.

Scale shift

Plot positions can be shifted in parallel on the trend chart. This function is useful when multiple graphs are overlap­ping. You can separate the plot positions while no other data is changed.

Scale shift Selectable within -100 to 100%

10% shift

20% shift

In order to reset the totalized value, ‘Trigger input’ and/or ‘Analog input’ can be specied. Touch the ‘None’ key in Page
3/7 for ‘Trigger,’ the one in Page 4/7 for ‘Analog input’ conditions. If you leave the setting to ‘None,’ the data is reset
only when ‘Start’ key is touched.

For details of the trigger input selections, please refer to ‘Peak Hold’function.

For the analog input resetting, choose one of the following conditions:

None No resetting by analog input. Reset only when ‘Start’ key is touched.
Value < Limit Reset when the measured value is lower than the limit value.
Value ≤ Limit Reset when the measured value is equal to or lower than the limit value.

Limit / Deadband

Specify Limit value used to reset the function result.
Deadband is used to prevent repeating of F value cal­culation execution and resetting when the measured
value stays unstable close to the limit value.
A positive deadband is used to reset at ‘Limit – Dead­band,’ while a negative deadband is used to reset at
‘Limit + Deadband.’
By choosing an wide deadband, you can set different
values for set and reset conditions.

5.6.3 ZERO/SPAN CALIBRATION

Zero/span calibration is used to compensate ne deviation in the measured signals. Field adjustments are performed
by applying actual input signals.
An offset is given to the signal by Zero calibration, and the signal gain is changed by Span calibration.
Calibration examples are given below.

ZERO & SPAN CALIBRATION

- Span (+) and Span (–) calibrations must have another calibration point (Zero or Span).

- Calibration points must be in relation to each other as follows: Span (–) point < Zero point < Span (+) point.
Otherwise the calibration will result in error.

- Switching the channel’s analog input type will reset the calibrated values.

Logic functions AND, OR, XOR, NOT

Math functions Square root extraction, Power

Accumulation Analog accumulation (until reset)

Filter Moving average, First order lag

Peak hold Peak (maximum value) hold, Peak (minimum value) hold

F value calculation Typically used to calculate the sterilization or disinfection time in predened conditions

Others Anemoscope (16 directions)

n PARAMETERS

• Measuring data: Specify input pens. With analog data, engineering unit data is used for computations. Data sampled

in the last cycle can be also used.

• Function data: Specify pen numbers used to store operation function results.

• Coefficients (K1, K2)

• Constants (A1, A2, A3)

• Other parameters: Number of data sampled to be used for the moving average function, Time constant for the rst

order lag operation, Reference temperature and Z value for F value calculation.

Caution 1

If ‘Last’ data is assigned to X1 and X2, the rst function data will be missed.

Measuring data and function data are used as numbers without an engineering unit. No adjustment between different
scales or engineering units are performed automatically.
The function operations are consecutively performed from the smallest Function Pen No. When you take one or more
function data as parameters for another function, be sure of the orders of functions.
Data range handled by these functions are from -1 x 10

10

to 1 x 1010. Function result values out of this range will be

handled as errors. For F value calculation, the range is from 0 to 1 x 10

10

.
The effective number of digits for the calculation result is 6 digits. Function result values exceeding the effective number
of digits may have intolerable deviations.

First order lag

Time constant is a response time for a step input (0 to 100%) to reach 63%. By setting the rst order lag lter, noises
and spikes contained in the input signal could be attenuated in the output signal. Specify measured data or function
data, with a time constant.
With 1 sec. or longer storing rate, function results displayed on the screen maintain the last value periodically, because
the function is executed the sampling rate and displayed on the screen.

Moving average

Multiple samples of input data are averaged. When the next sample is added, the oldest sample is discarded and
the new set of samples are averaged. By setting the moving average lter, noises and spikes contained in the input
signal could be attenuated in the output signal.
With 1 sec. or longer storing rate, function results displayed on the screen maintain the last value periodically, because
the function is executed the sampling rate and displayed on the screen.

9.5.1 DATA DISPLAY

The Alarm History view shows the date and time of the events, pen No. and its tag name, and the alarm message
(comment) pre-described for the particular status.
Sixteen (16) events are listed on the view, and the maximum of 1000 events can be searched and displayed with
the 512 MB and 1GB CF card. The capacity depends upon the CF card capacity (See Section “10. DATA & FILES”).
To the right top of the screen, the position of the presently selected alarm event among the total number of events is
indicated.
Blinking message line means that the event is not acknowledged yet. Touch it twice to acknowledge (once to move
the cursor to the line, twice to acknowledge), and it stops blinking. In order to acknowledge all events on the screen,
use ACK All button.

10. DATA & FILES

10.1 73VR21x FILES

Files required to store the 73VR21x data are created automatically when the 73VR21x gets started. Table below
shows the types of les.

Type Description File Name Extension
73VR21x Data File Data sampled by the 73VR21x Fixed (73VR) VRD21
73VR21x Alarm History File Alarm history data Fixed (73VR) VRA21
73VR21x Comment History File Comment history data Fixed (73VR) VRM21
73VR21x Control File Record pointer for 73VR.VRD21 Fixed (73VR) VRC21
73VR21x Parameter File Parameter settings such operation mode, pen setting Fixed (73VR) VRP21

CAUTION !

When you delete the data le in a CF Card, delete also the control le. In any event do not modify the control le. A
modied control le may destroy the data le.

WARNING !

Be sure to restart the 73VR21x before using a data le created by the 73VR21BLD congurator software. If not, the
data le will be destroyed.

DATA FILE

All 73VR21x data are stored in binary in single data le named ‘73VR.VRD21.’
An empty data le is already created at the startup of the 73VR21x using all available space. Once data recording
starts, sampled data are stored in this le. It means that the data le size is xed regardless of the data volume in it.
In order to conrm data recording, open the le in Retrieve view.
All data are stored in a single le even if multiple sets of data are recorded within a day, or if single or multiple data
are recorded over multiple days. Trigger data are stored also in the same principle. Therefore the user must be aware
that some data may be overwritten by another of different conguration settings if you keep recording after setting
new conguration.

ALARM HISTORY FILE

Alarm history is stored in binary in single data le named ‘73VR.VRA21.’ Analog alarm events and discrete signal
status changes (regardless of alarm setting) are recorded in this le. Alarm events are recorded regardless of the
storing method.
Like the data le, an empty alarm history le is already created at the startup of the 73VR21x. The le size is xed
regardless of the data volume in it.
Number of events stored in this le depends upon the CF card capacity. Refer to Table below.

CF CARD CAPACITY ALARM EVENT NUMBERS

128 MB 250
256 MB 500

512 MB, 1 GB 1000

The alarm history le is cyclic: data in the CF Card will be overwritten when the le is full.

COMMENT HISTORY FILE

Comment history is stored in binary in single data le named ‘73VR.VRM21.’
Like the data le, an empty comment history le is already created at the startup of the 73VR21x. The le size is xed
regardless of the data volume in it.
The comment history le is cyclic: data in the CF Card will be overwritten when the le is full.

CONTROL FILE

The control le contains the information to manage the data le. It is used to convert the le into compatible format
for use on the 73VR Data Viewer program or into .CSV format.
If this le is deleted, the data le is initialized. When storing the data le in the PC’s hard disk, store also the control le.

PARAMETER FILE

The parameter le contains information about the 73VR21x’s system and pen congurations. The 73VR21x reads
this le at the startup to apply the parameters.

10.2 DATA STORAGE TIME

Data storage time for one CF Card depends upon the following:

1. Storing rate

2. Data storing form

3. Number of channels

There are also CF Cards of different capacities.
Data storage time of a CF Card is calculated as follows:

Record Size

[Date Information] (bytes) + [One Sample Data] (bytes) x [No. of Channels] (points) = [Record Size] (bytes)

Number of Records

[CF Card Memory Size]* (bytes) / [Record Size] (bytes) = [Number of Records]

Data Storable Time

[Number of Records] x [Storing Rate] (seconds) = [Data Storage Time] (seconds)

Date information takes 8 bytes and one bit of sampled data takes 4 bytes with the oating point form, 2 bytes with
short integer form. No. of channels must include all channels set to ‘Enable.’
*[CF Card Memory Size] means the volume of data le (73VR.VRD21) created in the CF Card.

[Example]

Storing rate: 5 sec.
Data storing form: Short integer
Number of channels: 6
CF Card memory size: 118 MB (for 128 MB CF Card)
A record size is calculated as:
8 (bytes) + 2 (bytes) x 6 (points) = 20 (bytes)
The number of records which can be stored in this CF card is calculated as:
(118 x 1024 x 1024**) (bytes) / 20 (bytes) = approx. 6186598 (records)
Time duration usable for the number of records is:
6186598 x 5 (sec.) = 30932990 (sec.) = approx. 8592 hours. = approx. 358 days
**1KB-CF card’s memory size is calculated as 1024 bytes.
This calculated result is only for approximate estimation since the data le must be smaller than the full capacity of
a CF Card.

10.4 HOT SWAPPING THE CF CARD

The CF Card can be replaced while the 73VR21x is running.
The data sampled while the card is not placed is stored in the 73VR21x’s internal memory. Its capacity is enough
approximately for 5 minutes without a card. Be sure to get ready with a CF Card for replacement. If the CF Card
does not contain the les 73VR.VRD21, 73VR.VRP21, 73VR.VRC21, 73VR.VRM21 and 73VR.VRA21, they must be
created beforehand using the 73VR21BLD Congurator software. If the CF Card already has these les with stored
data, they will be overwritten.
Be sure to observe the following procedure. If not, CF Card and its data may be damaged or lost.

HOW TO REPLACE THE CF CARD

(1) Call up the Menu on the Display view and touch CF Card Eject key.
(2) Conrm that you want to remove the CF Card. If not touch Cancel.
(3) Conrm that the Menu now shows CF Card Insert key, and extract the card.

NOTE

No data retrieval or alarm history display is available while the card is removed.

(4) Insert a new CF Card, and touch CF Card Insert key.
(5) The 73VR21x will ask you if you want to reset the data le if one exist. Conrm that and touch OK.

CAUTION !

The CF Card cannot be removed while data in the internal memory is transferred to the card, during the card replace­ment or after the recording is complete. It may take certain time.

CAUTION !

The 73VRWV can perform FTP transfer while the 73VR21x is recording. The 73VR21x stores data in its internal
memory while the FTP is in progress. When the internal memory is full, the le transfer is stopped, and the 73VR21x
starts transferring data from the memory to the CF Card. Then with the transfer to the CF Card completed, the le
transfer to the 73VRWV is resumed. Due to this operating procedure, it usually takes longer time in a le transfer
when the 73VR21x is recording.

NOTE

Time elapsed (used le volume) since a card is removed can be conrmed on the Bargraph or the
Overview. The Data File Used Volume bargraph will indicated 100% after 5 minutes has been passed.
To use this function, choose Enable in the Display Setting.

NOTE

While the automatic comment entry is on, DO NOT execute a FTP data transfer.
