Every OVAL batch controller is fabricated, tested, inspected, and shipped from our factory under stringent
quality control. In order to maintain its design performance throughout its life, this manual offers the
operator the necessary installation, operation and maintenance information.
Be well familiar with these instructions before you place the controller in service and keep this manual at
the eld location for ready reference.
Also refer to the instruction manual for the pulse generator (owmeter) used.

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 specication.
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
specication 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 conguration.
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.
Valve opens and shuts off in two steps (reducing the initial velocity); this arrangement prevents not
➀
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.
If trouble occurs in the process for some reason, resulting in missing pulses, an overmeasurement,
➁
or parameter errors, an alarm can be made to go off.
(5) Reliable and simple to maintain.
Major circuits are built on printed circuit boards for reliability and simple maintenance.
➀
All inputs and outputs are isolated from each other by photocouplers.
➁
During power cycling, parameters and variables are retained in the E²PROM.

4.2 Installation
4.2.1 Installation Location (Indoor only)
Select an installation site where:
(1) Mechanical vibration, shock and corrosive gases
least exist.
(2) The air is dry and at around room temperature
and stable.
(3) A p l ace where is not e x p osed to the direc t
sunlight.
NOTE: Although the manufacturer guarantees
stated performance at ambient temperatures
from – 1 0 t o 5 0 ° C , i t is r e c o m m e n d e d t h a t
the ins trument be p laced in ser vice 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.
4.2.2 Panel
(1)
Use a rigid steel sheet with a minimum thickness of
1.6 millimeters. Recommended thickness is 3.2mm.
(2) If it is required to mount the computers side by
side, dimensions in Fig. 4.2 are suggested.
(3)
Recommended mounting height is given in Fig. 4.3.
4.2.3 Installation
(1) Insert the instrument through the opening in the
mounting panel.
(2) Hook the enclosure hold-down ttings to the slots
in the rear of the enclosure and, conrming that
the instrument is positioned on a level plane,
secure the instrument to the panel with panel-
mount ttings (Fig. 4.1).

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 2mm
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 sufciently 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.
2
, 2- or 3-conductor), or equivalent, must be used.
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.
