handling during transit.
1.1 Confirming the Tag
Product code and ratings appear on the counter tag. Make sure that the product you received complies
with the specifications in your order.
General Specifications and Product Code Explanation appear on pages 24 and 25, respectively.
When you inquire, supply complete information as to the product name, model number,
product number, ratings, etc.
1.2 Transportation Considerations
(1) The OVAL total counter can best be transported to the installation site in the shipping container
used for transit from our factory.
(2) Avoid giving impact shocks to the total counter during transit.
1.3 Storage Considerations
If the total counter upon receipt is to be stored for extended periods of time before installation, unexpected
problems could arise. If such is the case, the following considerations should be taken:
(1) The total counter can best be stored in the original package used for transit from the factory.
(2) Select a storage location that meets the following requirements:
 ☆ Free from rainwater and moisture
 ☆ Least vibration and impact shock
 ☆ In the room temperature and humidity environment (around 25℃ and 65% R.H.)
A total counter which has been idle for extended periods of time may possibly require internal
inspection. If such is the case, consult factory.
Tag (nameplate) shows ratings.

5. WIRING
5.1 Cables for Field Wiring
Use electrostatically-shielded, polyethylene-insulated, vinyl-sheathed control cables (CEVS 0.75 to 2mm2,
2- or 3-conductor), or equivalent, for input and output signal cables.
5.3 Terminal Block for External Connections
Before connecting the cables, ensure that the flowmeter (pulse generator) is compatible with this counter.
Acceptable combinations of these units can be determined by identifying their model number and
instrument number.
Invalid equipment combination can lead to a costly downtime. Be sure to reconfirm validity
following wiring connections.
5.2 Field Wiring and Electrical Connections
(1) It is recommended that cables be routed through conduits.
Be sure to route the power cable separate from the input and output signal cables.
(2) Keep the cables away from other power cables or power circuits if any, to prevent stray current pickup.
If inductive interference is suspected, use a capacitor or surge suppressor where necessary.
(3) Use crimp-style terminals to ensure good electrical connections. Terminals for connections are located
on the back of this instrument.

7. FUNCTIONS AND OPERATION
The counter is designed to show the following
variables on the display using "MODE" and "RESET"
pushbuttons.
7.1 LCD Counter Display
Upon each depression of "MODE" button, the LCD
display scrolls through available variables as shown
Only incoming pulses having small periodic
variation produce meaningful readins.
(See section 7.3.)
RESET button is operative only in this mode.
The counter resets to zero upon "RESET"
button depression.
7.2 About the Displayed Messages during Operation
(1) Ordinary operation
"MODE" switch is turned "ON"
⇒8 bars appear.
⇒Immediately turning "OFF" scrolls the window
to the next one. ⇒Holding turned ON until the last bar disappears results
in "prolonged depression" processing (Turning OFF
before the last bar disappears results in the same
behavior as in ①to take place.)
※ Prolonged operation: An operation required for Normal
mode ⇔Parameter review mode selection, finalizing
the parameter setting, etc.
Indicates a countdown before "prolonged depression"
processing takes place.
(2) Prolonged operation
"MODE" switch is held turned ON without turning
"OFF" immediately by removing the fingers.
⇒Bars begin to disappear from the leftmost one.
7.3 Total Flow and Instantaneous Flowrate Calculation and About Factored Pulse Output
(1) Total flow
Each time a single pulse (after frequency division by hardware means) arrives at the CPU, "Parameter
F×Parameter H" is added up to the current reading of total flow.
●The LCD shows a reading down to the decimal places set at "Parameter SP" menu.
●When the reading has reached its maximum reading (99999999), the reading returns to zero.
(2) Factored pulse output
Produces a pulse output to read in the unit set at "Parameter Pu" menu.

(3) Instantaneous flowrate
When the CPU accepts count (Parameter A) of pulses sampled within sampling time (Parameter At )
[sec], its period or the interval of occurrence T [sec] is measured. The instantaneous flowrate is then
determined by the following equations:
Hourly flowrate b1=3600×F×H×A/T
Per-mimute flowrate b2= 60×F×H×A/T
1.b1 shows a reading down to the decimal places set at "Parameter bP" menu.
2.b2 shows a reading down to the decimal places of b1 + 2 addditional places.
3.In the absence of any incoming pulses within sampling time At [sec], the instantaneous
flowrate reads "0".
4.If the instantaneous flowrate exceeds 99999, the reading remains at "99999".
7.4 Jumper, Switch, Potentiometer Setup and Adjustment
◎The counter is configured to customer specifications at the factory and no further adjustment
is required except for later changes or adjustment.
Alteration and adjustment above requires removal of internal electronics.
7.4.1 Construction of Internal Electronics Assembly
In the pulse type, the internal assembly consists of a display board and a power supply board. The
analog type (option) has three boards with an additional F/I board. The power supply board and F/I board
connect to the display board. At the back, a terminal block for external connections is found. See "How to
Remove Internal Electronics Assembly" outlined on the next page.

7.4.5 How to Change Output Signal and Pulse Width
Output pulse width of this counter is set to a default of 1ms., and if the customer's option is 5, 6, 7, or
9 in supplementary code ⑨of in Product Code Explanation on page 26, the product is adjusted to the
specified pulse width before shipment. But if later changes are desired in the field, you can change it to a
new setpoint at the parameter Pon setup menu.
Select a pulse width appropriate for the flow range to ensure that pulses will not
overlap.
7.4.6 Procedure to Set up and Change Analog Output (option) and Adjustment
●By changing setpoints at parameter AF menu, you can change the full scale flowrate (flowrate to
produce a 20mA output).
●In the mode at parameter A04 and A20 menus, you can also trim the 4mA/20mA.

7.5 Parameter Setup Procedure
7.5.1 Procedure to modify a parameter
Given below is the parameter setup procedure:
For complete detail of MODE and RESET switch operations in steps ①, ②, ⑥and ⑦, see
"Table 7.5 Menu Trees and Switch Operation" on page 19.
7.5.2 Procedure to Enter a Parameter
The procedure to enter a parameter (switch operations sequence in "Parameter Setup Mode") comes in
three ways (numerical setup, decimal point location setup, and analog 4/20mA trim) that follows:
Meanings and functions of individual parameters appear in the Parameter List on pages 20 and 21.
Kind 1 Numerical setup parameters (F, H, Pu, At, A, AF, dAn, Pon)
The blinking digit in the parameter setup mode is the place of interest.
MODE …Each time the switch is turned on, the place of interest moves one place to the left.
RESET…Each time the switch is turned on, the figure in the blinking place increases by one.
Or exponential sign toggles ("E", "-", etc.).
→Following the parameter setup, hold the MODE switch turned ON for more than 2 seconds (the new
setting is established and the screen returns to the review mode).
① In "Measure Mode (normal mode)", turn MODE switch ON for more than5 seconds to go into"Review Mode".
②Using MODE and RESET switches, show the parameter you want to modify.
③Turn MODE switch ON for more than 2 seconds to go into "Parameter Setup Mode".
④ Using MODE and RESET switches, set up a new parameter. (See Para. 7.5.2 below for the procedure.)
⑤ Following the parameter entry, turn MODE switch ON for more than 2 seconds to go back to "Review Mode".
⑥Using MODE and RESET switches, show the title (= one from bdAtA, AL, AnA, PuLSE, CorrEct, or Co).
⑦Turn MODE switch ON for more than 5 seconds to go back to "Measure Mode".

●
Turning MODE "ON" moves the blinking digit one place to the left ("E").
●Turning RESET "ON" increases the figure by one ("2" →"3").

E-122-8-E
1
Kind 2 Decimal point setup parameters (bP, SP)
In the parameter setup mode, a figure representing the decimal places of interest flickers.
MODE …Not used in the setup process.
RESET…Each time the switch is turned ON, the decimal point moves one place to the left and the
figure increases by one.
→When the decimal point appears at the desired location, hold MODE turned ON for more than 2
seconds. (This establishes the setting and the window returns to the review mode.
Kind 3 Analog output 4/20mA trim
●During the analog trim, keep on monitoring the analog output with a milliammeter or voltmeter.
Given below is the 4mA trim procedure (the same holds true with 20mA trim).
(1) At "A04 4.000," hold "MODE" turned ON for 2 seconds to go into the parameter setup mode; the
least significant digit "0" at rightmost blinks on and off and a 4mA simulated output from the register
appears.
(2) Set the milliammeter reading in the procedure below.
(If it reads 3.988mA, for example, set to "A04 3.988.")
Following entering the setting, MODE turned ON for more than 2 seconds to establish the setting.
(3) Analog output is trimmed: make sure of the milliammeter reading once again.
(The indicated reading returns to "A04 4.000" (the least significant digit at extreme right blinking) now.)
●If the reading is within the tolerance with respect to 4mA, by holding MODE turned ON for 2 seconds
the second time, you can exit the setup mode.→Adjustment is complete. Returns to the reveiw mode.
●If the reading is still outside the tolerance, repeat step (2) above.
Example: Parameter "bP" (decimal place in instantaneous flowrate)
Relative to the figure at right of
decimal point, this point moves. A figure representing the decimal places of interest (flickers)
Turning RESET button ON, the figure increases by one
("0"→"1"→"2").
If a setting above (bP=2) is chosen, the instantaneous flowrate reads [b1 □□□.□□].
Example: Parameter "A04" (4mA trim)
MODE …Each time the switch is turned ON, the digit of interest moves one place to the left.
RESET…Each time the switch is turned ON, the figure of interest increases by one.
Digit of interest (blinking)
●Turning MODE "ON," the blinking digit moves to the left.
●
Turning RESET "ON", the figure increases by one ("0" →"1.")

7.5.3 About Dummy Output Features (special functions)
By the following steps, a 1Hz or 10Hz simulated factored pulse train can be furnished irrespective of
flowmeter measurement.
This feature is not available with the unfactored pulse output specification.
(Dummy output is not featured for unfactorred pulse output.)
●1Hz simulated output mode (dummy output 1 mode Code: Pd1)
①According to the Table 7.5 "Menu Trees and Switch Operation" (page 19), show dummy output 1 ("Pd1 1")
on the LCD.
②Turn MODE button ON for more than 2 seconds to go to the dummy output run mode.
(The display shows "Pd1 0".)
③Operation within the dummy output run mode
●Turn RESET button ON →Dummy output appears and the counter counts in sync with the pulse output
produced.
●Turn MODE button ON →Dummy output stops.
●Hold MODE button turned ON for more than 2 seconds→Dummy output run mode is terminated,
returning to the state ①.
1.The procedure above also applies to the 10Hz simulated output mode (dummy output 2 mode
Code: Pd2).
.Pulse width is set by parameter "Parameter Pon".
7.5.4 Parameter Initialization
①Remove the external power source. (If provided with the battery, take the battery out as well.)
② While pressing the MODE switch, turn the external power on. (If provided with the battery, put the battery in.)
③The LCD lights up in all figure places. (Keep the MODE switch pressed.)
④When the screen shows "PA. rESEt", release the MODE switch to turn "OFF"→Initialization is complete.
(Holding the MODE switch pressed after "PA. rESEt" is shown causes the modes to go to the measure
mode without initialization.)
Parameter initialization is the step to be taken upon detection of a parameter error "PA.Err. 1"
or other erratic condition. Do not take this step unless absolutely necessary.

7.5.5 About Alarm Output (option)
●When the instantaneous flowrate exceeds (or falls below) a preselected setpoint, the counter lights up a
front-panel LED and, at the same time, produces a remote alarm output (non-contact relay).
●Alarm comes in Alarm 1 and Alarm 2 which can independently be established.
For parameter menu trees associated with alarms, see "Table 7.5 Menu Trees and Switch
Operation" on page 19.

Message Name Description Coping action
PA. Err. Parameter setup error
An attempt is made to rewrite a parameter
while parameters are write-protected. (In
the standard model, write-protect feature is
set in OFF and will not appear.)
Can be reset by placing No.1 of display
board SW3 in OFF. (This enables you to
change parameters.)
PA. Err. 1 Parameter error 1 Backup data retained for parameters
has been damaged.
CPU initialization and then reconfiguration
of parameters are required.
PA. Err. 2 Parameter error 2
Some of the backup data retained for
the display mode, accumulate total flow
reading, or resettable total flow reading
have been damaged.
Can be restored with MODE switch, but
the accumulated total flow and resettable
total reading will be reset to 0.
PA. Err. Pu Pulse weight error
Pulse weight "Pu" setting is too small
with respect to meter factor "F" and
conversion factor "H."
Change the setting to an appropriate
value that the relationship between F, H,
and Pu satisfies the following formula:
F×H≦Pu≦F×H×10000

AnA. Err. Analog output error
Analog output level is exceeded 120%
of full scale for either reason:
①Flowrate excessive
②Analog full scale setting too small
①:Reduce flowrate.
②:Select an appropriate analog full
scale setting relative to the flowmeter
specification.
Out. Err. Pulse output error
Pulse "OFF" width in the factored pulse
output falls short of 1 msec for either
reason:
①Flowrate excessive
② Factored pulse width setting too great
①:Reduce flowrate.
②:Choose an appropriate factored pulse
width "Pon" relative to the flowmeter
specification.
