1. BEFORE YOU BEGIN

This device is shipped after sufficient inspection at factory. After receiving this device, check if there is no damage on the external appearance. 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 Confirmation of product name plate

This device is shipped according to the specifications. The product name plate is attached to the right side surface of batch counter. Check the standard specifications and description of product number of device correspond t o the ordered specifications.

Fig. 1.1 Example of attachment of product name plate

◆ When you make an inquiry, please inform us of product name, product symbol (TYPE), and production number (SERIAL No.) etc. described on the product name plate. ◆

1.2 Transportation Considerations

(1) The batch counter 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 counter during transportation.

1.3 Storage Considerations

If the batch counter 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 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°C and 65% R.H.)

2. GENERAL

Combined with a flowmeter and a shutoff valve, the batch counter passes a predetermined amount of the process fluid in batching operations. Built around a single chip microprocessor, this versatile, compact, and lightweight counter 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.

a. As setting, start, stop, and reset of batch quantity are carried out with touch panel in front of measuring

instrument and push button switches, assured operation is possible.

The display part is equipped with color LCD module with 3.5-inch touch panel. Although it is small, it is easily viewable.

Start and stop, and reset are operated with push button switches and setting of batch quantity is operated with touch panel to prevent wrong operation.

(2) Wrong setting can be prevented.

As the operation of touch panel can read out nine types of batch quantities that have been registered, wrong setting can be prevented.

(3) Correct quantitative control is possible.

As an operation signal that opens or closes the valve at 2 stages, correct quantitative measurement is possible.

As the overshoot quantity due to response delay of valve can be corrected by setting the forecasted overshoot quantity, correct quantitative operation is possible.

(4) A system can be configured easily.

As start stop, and reset operations are enabled by external signal and the batch completion output can be obtained, the interlocking with other control system is enabled easily.

(5) The safety of process can be ensured.

The valve is operated by 2-stage open and 2-stage close. The generation of static electricity in piping or tank when the operation is started is prevented and piping shock due to water hammering when the valve is closed is prevented.

If a defect is generated in the process and the pulse is not input or fluid leaks exceeding the setting batch quantity, an alarm signal will be output.

(6) This device is of high reliability and the maintenance can be implemented easily.

a. As the internal configuration is unitized, this device is of high reliability and the maintenance can be

implemented easily. b. All I/O systems are isolated by photocoupler / relay etc. c. When the power supply is turned OFF, total flow value and each setting value will be held in FeRAM.

Fig. 4.1 Outline Dimensions

4.2.1 Installation Location (Indoor only)

Choose to install in the place where: (1) Mechanical vibration, shock and corrosive gases least

exist.

(2)

The air is dry and at around room temperature and stable. (3) A place not exposed to the direct sunlight. (4)

A place where dust is almost none

NOTE:

1. In installation and through daily operation, pay due care so as dust not to accumulate in the place.

2.If chemical solvent etc. may be attached to

the front surface, it is recommended to use the protection sheet or touch pen separately to protect the decorative sheet on the front surface.

Although the manufacturer g u a r a n t e e s

stated

performance at ambient temperatures

from –10 to 50℃ , it is recommended that the instrument be placed in service at room

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 (CEVS, 1.25 to 2mm2, 2- or 3-conductor), or equivalent, must be used.

For output signal cables, insulated, vinyl-sheathed cables (CVV, CVVS … JIS C 3401) are suggested. (2) Cable shields must be connected to terminal “G” of the counter. At the probe end, leave the shield wire end

unprepared.

(3) For the connection cable to D-SUB connector, use 25-pin soldering type (male). Create it as a dedicated part.

For an electric wire, use the electric wire "equivalent to UL1007, 0.5mm2 ".

5.2 Wiring Connections

(1) Conduit work is suggested for field 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 sufficiently 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 counter (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. 5.2).

(5) For the wiring, ensure approx. 30cm of allowance to enable the easy maintenance.

5.3 Identifying the External Connection Terminal Block

On the rear surface of this device, there are terminal block fixed to input board (terminals No.1 to 8, 17 to 24), terminal block fixed to output board (terminals No.9 to 16, 25 to 32), D-SUB connector fixed to power supply board (25-pin female).

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.
