1. BEFORE YOU BEGIN
Before leaving the factory, every OVAL product is thoroughly inspected and tested and is shipped in rst-
class condition. When received, it should be carefully inspected for any indication of rough handling during
transit. In this section, instructions necessary for handling this instrument are described. Make yourself
familiar with these instructions. As for other instructions, refer to respective sections.
If you have something to inquire, contact the nearest OVAL authorized service station in your district.
1.1 Confirming the Nameplate
OVAL batch controllers are individually adjusted to the
customer specication.
Make sure, by comparing the model code and ratings
stated on the nameplate or tag attached to the top of
the housing against the GENERAL SPECIFICATIONS
(page 30) and PRODUCT CODE EXPLANATION (page
31), that the product you received conforms to the
specication in your order.
◆When you inquire, please specify the product name,
model No., serial No., ratings, and other pertinent
information.
1.2 Transportation Considerations
(1) The batch controller should be transported and stored in the same package used for transportation
from our factory if circumstances permit.
(2) Avoid giving impact shocks to the batch controller during transportation.
1.3 Storage Considerations
If the batch controller upon receipt is to be stored for extended periods of time before installation,
unexpected problems could arise. In a case like this, the following considerations should be taken:
(1) The batch controller 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°C and 65% R.H.)

2. GENERAL
Combined with a owmeter and a shutoff valve, the batch controller passes a predetermined amount of the
process uid in batching operations. Built around a single chip microprocessor, this versatile, compact, and
lightweight controller is designed for ease of operation. It saves time and effort in many processes, such as
blending materials, dosing with additives, transferring materials from one tank to another, or shipping from
an outlet, at chemical, food, paint plants or elsewhere where streamlined production lines are desired.
2.1 Features and Functions
(1) Easy operation.
Front panel key switches for batch setup, start, stop, and reset for accurate operations.
(2) Accurate batch control.
Valve control output comes in two steps to open and shut off the valve for far more accurate metering
than with a single batch control output.
(3) Simple system conguration.
Can control the system with start, stop, and reset signal arriving from a remotely located point. Also
available is an end-of-batch signal. All these make interlocking with other control systems simple.
(4) Increased process safety.
➀ Valve opens and shuts off in two steps (reducing the initial velocity); this arrangement prevents not
only static electricity generation in the pipeline or in the tank at startup, but also water hammer, or
hydraulic shock, to the pipeline at valve closure.
➁If trouble occurs in the process for some reason, resulting in missing pulses, an overmeasurement,
or parameter errors, an alarm can be made to go off.
(5) Reliable and simple to maintain.
➀Major circuits are built on printed circuit boards for reliability and simple maintenance.
➁All inputs and outputs are isolated from each other by photocouplers.
➂During power cycling, parameters and variables are retained in the E²PROM.

(2) The air is dry and at around room temperature
and stable.
(3) A place where is not exposed to the direct
sunlight.
NOTE: Although the manufacturer guarantees
stated performance at ambient temperatures
from –10 to 50°C, it is recommended that
the instrument be placed in service at room
temperature.
(4) Provide a sufficient working space behind the
instrument – at least 50 centimeters from the
back panel of the instrument to facilitate wiring
and servicing.

5. WIRING
NOTE: See “WIRING” in the pulse generator instruction manual.
5.1 Cables for Field Wiring
(1) For flowmeter input signal cable, electrostatically shielded, polyethylene insulated, vinyl-sheathed
control cables (CVES, 1.25 to 2mm2, 2- or 3-conductor), or equivalent, must be used.
For output signal cables, insulated, vinyl-sheathed cables (CVV, CVS … JIS C 3401) are suggested.
(2) Cable shields must be connected to terminal “G” of the controller. At the probe end, leave the shield
wire end unprepared.
5.2 Wiring Connections
(1) Conduit work is suggested for eld wiring.
NOTE: In conduit work, use separate conduit for power cables and signal cables in order to minimize
the possibility of stray current pickup.
(2) Route cables sufciently away from other power lines or power circuits, if any, to reduce the possibility
of inductive interference to a minimum.
(3) Use crimp-style terminal lugs for connections and ensure good electrical contact. Connection terminals
are found at rear of the controller (Fig. 5.1).
(4) In applications where an inductive load (valve, counter, etc.) is driven, do not fail to use a surge
suppressor (see Fig. 5.3).
(5) Give a 30-centimeter approx. allowance to the wiring harness to allow internal assembly withdrawal for
servicing.
5.3 Identifying the External Connection Terminal Block
At the rear of the controller, terminal block (terminal Nos. 17-22) secured to the output board and removable
terminals block (terminals Nos. 1-8, 9-16) secured with four screws are found.
CAUTION: Before making wiring connections, verify the validity of flowmeter (pulse generator)
and receiving instrument combination by referring to their product No., tag No., etc.

6.3 Output Functions
NOTE: For the information about the front panel display functions not described in this section, see
Section 6.1 on page 11 and Table 11.1 on page 30.
(1) Alarm Output
Upon detection of missing pulse, overmeasurement, or parameter error, the controller produces an alarm
output.
The LCD 1 ALM then comes on (only upon detection of missing pulses or overmeasurement) and
completes a circuit across terminals 21 and 22 (Relay contact output Form “a” contact) (upon detection of
all alarms).
a. Missing pulse alarm detection (Fig. 6.2)
Following

(2) End-of-batch output
When a ow signal reaches the target batch quantity during a batch process, an output is produced.
The LCD 1 END then comes on and completes a circuit across terminals 9 and 10 (Non-contact relay
output, Form “a” contact).
(3) Scaler
If incoming pulse signal is of unfactored pulses, a constant inherent to the owmeter used is multiplied in
the scaler; conversion takes place into quantities in industrial engineering units of measure in integer; the
resultant quantities are used for batch processes.
For the setup procedure, refer to Sec. 9.1.
(4) Input frequency division (scaling)
There are two approaches in setting up the input frequency division. One is a frequency reduction by
hardware, using a jumper and the other is a frequency reduction by software, using the front panel control
keys.
For the setup procedure, refer to Sec. 9.1 and 9.5.

8. OPERATION
8.1 Preparation Before Operation
(1) Make sure to see that the controller and associated equipment are correctly installed, connected and
wired with no place left unnished.
WARNING
Make sure to see that the power terminals are connected to a source of the rated voltage.
Connecting an incorrect power voltage source may ruin the controller.
(2) Make sure that the shutoff valve is correctly wired and set. For details, see the instruction manual for
the shutoff valve.
8.2 Preoperational Checks
Make sure to see that the shutoff valve operates properly without allowing the flow.
(Run this check daily before operation.)
•
(1) Supply power to the controller. Conrm that LED
STOP indicator becomes illuminated and that
displays LCD 1 and LCD 2 come on.
(2) Enter some arbitrarily set quantity of a batch.
NOTE: See Section 9.1.1.2, “Example of Bach
Setup” on page 21.
(3) Press
START
▲
key to make certain that the
shutoff valve opens.
(4) Press STOP
ROT. key to make certain that the shutoff
valve closes properly.
(5) Repeat steps (3) and (4) above several times to make certain that the shutoff valve opens and closes
properly.
(6) If the controller features remote start and stop, repeat steps (3), (4) and (5) above also at the remotely
located point.
8.3 Operation Sequence
(For information about the control keys, see Section 6. FRONT PANEL DISPLAY on page 12.)
(1) Turn on power.
(2) Allow the LCD 1 display to show the batch setting.
(3) Set the target batch quantity desired.
The unit of measure is indicated on the unit label at lower right below the LCD 2 display.
(4) Press
RESET
◀key to reset the batch total counter of LCD 2.
(5) Press
START
▲key to start up and the controller will start batching operations.
CAUTION
If the controller receives even a single pulse during the transitional time between RESET key
and START key depressions, it will fail to start. (For details, see Question 3 in Section 10.4
Q&A Controller Behavior in Standby Mode.)

(6) To perform a repeated metering of the last measured batch, all you need is to press the reset key to
bring the total counter of LCD 2 back to zero and then press the start key:
Press
RESET
◀key to reset the total counter.
Pressing
START
▲key readies to restart the last metered measurement.
NOTE: For metering different batches, select a new target batch setting each time.
(7) Emergency shutoff (or temporary interruption)
To bring the controller to an emergency stop, press STOP
ROT. key. The shutoff valve will come to a full
closure.
Pressing
START
▲key will resume operation and continue metering the remaining quantity from the
point of interruption.
In this way, safe and accurate measurement can be achieved.

8.4 Confirming the Two-stage Valve Opening and Closure
You can conrm the valve opening and closing in two stages by one of the following two approaches:
Once set the initial and final setpoint at “0,” choose a batch setpoint somewhere above “1” and press
START
▲and STOP
ROT. key to verify proper shutoff valve actuation.
If simulated pulses (from OVAL pulse checker PC2201, for example) are available, you can confirm
proper batch operation of the shutoff valve by setting the initial and final setpoint at any point, pressing
START
▲key, and then feeding a simulated pulse train.
NOTE: The target batch setting should be greater than the sum of the initial and nal setting.
8.5 Description of Batch Operation
NOTE: Operation can best be understood by referring to the operation time chart in Fig. 8.2 below.
Upon depression of
START
▲key, the valve opens to a predetermined position (initial owrate). When a
predetermined quantity (from point A to point B) has been delivered, the valve opens fully; when metering
has reached point C, the valve automatically throttles the flow and maintains a predetermined valve
position (nal owrate).
At point D, a closure signal is generated. However, due to a time lag in valve actuation, inherent to the
type of valve used, the valve actually close at point E. If an overshoot, or overmeasurement, exceeds a
predetermined quantity, the controller produces an alarm.
Safe and accurate measurement is thus achieved. In this connection, valve positions A →B and C →D
must be preselected on the part of the valve.

9. SETTING UP OR CHANGING PARAMETERS
Setting up parameters and variables other than those to be set up with controller’s front-panel control keys
requires internal assembly removal since it involves conguring the internal boards of the controller.
NOTE: Defaults (your specications inclusive) appear on the parameter settings label attached to the
side of the controller. ⇒See page 22.
9.1 How to Change Parameters (batch setup and other setup modes)
9.1.1 Batch Setup Mode
To set up a batch, holding STOP
ROT. key depressed for more than 3 seconds while the following conditions
are met.
The front LED SET lights up and the LCD 1 (batch setting) blinks on and off. Target batch setpoint
alteration is now acceptable.
Conditions required for changing batch setpoints
(1) The display does not show the grand total.
(2) A missing pulse alarm has not been detected along with its output.
(3) An overshoot alarm has not been detected along with its output.
(4) An end-of-batch signal has not been produced.
(5) A batch operation is not in progress.
CAUTION: 1. If an alarm output exists, reset it before you work.
2. While the controller is not in the batch operation but is only counting
incoming flow pulses for totalization, a change in batch setting is
acceptable.
9.1.1.1 Operation (batch setup mode)
On seeing the front panel SET illuminated and the whole LCD 1 ickering (in response to the procedure
above), you can change the current setpoint by the following procedure.
Batch Setup Mode comes on and LCD 1 (batch setting) blinks.
