1-4 General description
This machine is a compact type indicator unit that displays the constantly changing production
quantity on the shop floor. It helps you grasp the ongoing status of production at a glance and
also contributes greatly to the rationalization of production such as analysis of manufacturing
processes and improvement of workers’self-control.
With a built-in microprocessor, the machine allows you to set or change the six types of basic
data: Tact, Target,Actual, Advancement, Clock, and Working hour.
As for a production quantity, the machine counts up the signals from limit switches etc.,
calculates the advancement based on the tact and working hours, and displays each of the
data. The machine also features a number of functions, which include the “Clear time
function”for automatically clearing the Plan, Actual, and Advancement when a preset time is
reached, and the “Stop function” for temporarily suspending the Plan calculation even during
working hours.
Low in price.
Compact, lightweight, and space-saving.
Bright & easy-to-see 1-inch red color 7-segment LED display.
Equipped with a built-in microprocessor and a timer.
Offers a range of display variations and allows you to change display types by keyboard
operation.
Includes the stop function.
Includes the data backup function, which allows data to be maintained even at a power
failure.
Can select between use and no use of the Working hour.
When the Working hour is not used, a switchover is made between the operating and
stopped status in response to ON/OFF of external contact inputs.

1-8 Installation
1-8-1 Installation procedure
(1) Mount the mounting stay to the installation area with wood screws or small screws.
Mount the main body onto the mounting stay with ornamental screws loosely tightened.
* In the case the mounting stay is attached to the main body, remove the two ornamental
screws from both sides and detach the mounting fittings.
(2) To the Actual count (UP terminal) on the input terminal block, connect the non-voltage
contact for counting up the input signals from relays, micro switches, limit switches, etc.
Also, establish a connection to each of the other input terminals as needed.
(3) Determine the angle at which the display panel (data display and LED’s) is easy to see
and operate, and then fix the main body by fully tightening the ornamental screws on
both sides.
(4) Insert an applicable plug firmly into the DC jack and supply the power of DC12V/0.8A or
more. (Applicable plug: φ2.1(I.D.) x φ5.5(O.D.) mm with center negative)
The main body has a build-in microprocessor, which means there is a possibility that the data
may collapse due to power fluctuation or flicker. Take power supply from a location free from
power fluctuation or flicker.
For the non-voltage contacts to be connected to the input terminal block, use the ones with less
chattering that can steadily turn on/off the voltage/current of 12V/10mA.
1-8-2 Input terminal block
For the input signals to be connected to the terminal block, use the ones with less chattering
that can steadily turn on/off the voltage/current of 12V/10mA. Keep a time interval of at
least 50msec between input signals. Also, keep 50msec or more from when one input
signal is turned off till another input signal is turned on.

Chapter 2 How to Use
2-1 Function settings
Before using the machine, you need to make settings for the following items. Read the
description carefully and make suitable settings for your intended application.
Setting an operation type
Select an item shown on the display of the machine to set a desired operation type.
For an operation type, you may make a choice from among the seven patterns in all by a
combination of “Target,”“Actual,”“Advancement,” “Accomplishment rate,”“Plan,”and “Tact.”
Setting use or no use of the Working hour
When the Working hour is used, the machine calculates the planned quantity based on the
registered data of working hours.
When the Working hour is not used, the machine calculates the planned quantity based on
ON/OFF of external input signals.
Setting the stop input logic
Set “Positive” or “Negative” for the logic of a stop input signal.
The resulting operation (operating/stop) differs depending on whether the Working hour is set
to be used or not used.

2-1-1 Setting an operation type
The machine is so designed that a setting can be made from among seven operation types.
When using the machine with any operation type other than the type 123
(Target/Actual/Advancement), affix the attached command sticker onto the case.
Display items [1] Target: The target production quantity of the day (fixed
value).
[2]Actual: The production quantity up to the present time.
[3]Advancement: The degree of advancement relative to the
planned production quantity at the present
time.
[4]Accomplishment rate: The rate of accomplishment to the planned
production quantity at the present time.
[5] Plan: The planned production quantity at the present
time (changes over time).
[6] Tact: The time required for production per product
(shown in seconds).
