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.

b.

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

c.

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.

a.

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

b.

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.

a.

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.

b.

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.

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

8.5 Batch processing and various functions

(1) Usual operation

At the same time when START button is pressed, the valve is opened to the predefined aperture. If a constant

quantity of fluid flows (initial setting value = from point A to point B), the valve will be fully opened.

If the measurement up to point C is completed, the valve will be automatically closed and kept to predefined

aperture.

If the fluid reaches point D, the stop signal will be transmitted, however, the valve will be actually closed at point

E because the valve operation will be delayed.If the value is integrated up to batch setting volume, the

completion monitoring timer operates and outputs the completion signal after the monitoring time is over. If the

value is totalized up to batch setting volume, the completion monitoring timer operates and outputs the

completion signal after the monitoring time is over. If the totalized value exceeds the point F within the completion

monitoring time, the overrun alarm will be output.

The adjustment of aperture from valve A to B and C to D should be preliminarily set on valve side.

(2) Temporary stop operation

If you press STOP button, SV/MV output will be turned OFF and the operation will be temporarily stopped. PUMP

output will be stopped after delay timer.

If you press START button, the operation will be restarted.

If the operation is temporarily stopped at upper limit flow rate, both of SV and MV will be turned ON at the restart

and the flow rate will reach the upper limit flow rate (not becomes 2-stage open).

If the operation is temporarily stopped at restricted flow rate, only SV will be turned at the restart and the flow rate

will reach the restricted flow rate.
