1. Explanation of product
1.1 Product outline
This product is the alarm setter of the plug-in structure which considers a DC voltage (or DC current) signal
as an input, and outputs the relay contact signal of four points (maximum) as compared with the set-up operation
set value.
This product is the type corresponding to the software that has a LCD function and a scale can set up arbitrarily
according to the amount of processes. The real scale display function of an input, the dead band setting function,
the contact delay setting function, and the starting delay setting function are built-in. It can correspond
to various process instrumentation flexibly.
1.2 Features of product
 Setting accuracy is ±0.1％ (％ for input span). Display accuracy is ±0.1％±1digit (％ for input span).
 Between input, output, auxiliary supply and cases, withstand voltage is AC2000V design.
 The display of real scale by LCD. And, setting can carry out freely by the front button switch.
It can correspond to scaling change etc.
 Nonvolatile RAM offers the power failure guarantee of the set value.
 Sufficient derating of uses parts, and reduction of inside generation of heat improves reliability.
 The back light is turned on at the case of key operation. 30 seconds after key operation is completed, the
back light puts out the light.
 By the pre-alarm function, the efflux in contact delay time is displayed by blinking of a monitor lamp.
(ON/OFF of prealarm can be selected by setting.)

・The decimal point position change of scaling is made by the minimum value scaling.
If the decimal point position is changed, the decimal point position of maximum value scaling and operation values
1 to 4 will also change. If the decimal point position is changed, please be sure to check the set value of
a maximum value scaling and an operation value.
・An operation value can be set up in -25 to +125％ of the measurement display range (minimum value scaling to
maximum value scaling).
(Example) Input 4 to 20mA, Operation value -25.0, Output mode is "Low" setting.
It becomes L detection in 0mA of inputs, it is also possible to use it as
disconnection detection.
・After setting change, in case a set value combination error occurs, it becomes a setting error display.

● About transition of a contact
In DC load switching, transition of a contact may start and a contact may
not return by uneven connection.
A contact evaporates locally with arc heat, what carried out contact
evaporation to + polarity → - polarity carries out the adhesion deposition
of this, and a single-sided convex opposite side serves as a concave.
〈Measure〉Be sure to use each relay within a rated load.

Please refer to the connection diagram for wiring.
The polarity of ( ) is the case where a control power supply is DC.
The tightening torque of mounting screw. M3.5：0.7 to 0.9N･m (7.1 to 9.2kg･cm)
< Caution >
 Please do not make a wiring change of the input and auxiliary supply in an energization.
Please be sure to work after intercepting a source.
 Please do not touch a terminal etc. at the case of cleaning and check.
 A fire-damaged accident may be caused by the wiring difference in auxiliary supply or input.
Please be careful of wiring enough. And, check in the place which has combustibles, an inflammable medicine,
inflammable gas, etc. in environment is also dangerous.
 When inductive loads (electromagnetic relay, etc.) are connected to output contact, It recommends attaching
diode (or surge killer) etc. near the load.
3.4 Cautions on mounting
 State of mounting
There is no limit of mounting position. Mounting instruction can select 35mm width DIN rail mounting and
screw mounting. In screw mounting, please mount with M4 screw. (However, the screw is not attached.
And, please give the mounting torque of a screw as 1.08 to 1.47N･m (11 to 15kg･cm)).
Should establish of side-by-side mutual mount space 5mm over up. A vertical interval should prepare
space 90mm or more in consideration of radiation and a wiring space.
 State of wiring
Please separate wiring of input and output and perform consideration to noise. And, please separate from
a line with the power line used as the source of a noise and steep voltage, and current as much as possible.
Please use shielding wire for the bottom of the remarkable environment of a noise.
 Conditions of environment
(1) The range of the temperature and humidity of environment.
Please give temperature and humidity as a next range from operation of each device.
Temperature：-10 to +55℃，Humidity：5 to 90％RH (Non condensing)
(2) Environment atmosphere

● Notes after a setting change end
After setting change is completed, please check that set value has been changed with a set value display mode.
After confirming the changed set value when being different from the established set value, please establish
it once again.
● If a unit display (UNIT) is set up. (９)
● If a minimum value scaling (MIN) is set up.
Note(９) If you do not have the unit you wish to use, please use a combination of "no unit" setting and
seal (accessory).
Note(10) After set value changed, displays the change set value.
Note(11) The number of the top digit becomes "-"(minus) after 0 to 9.
Note(12) The number of digits other than the top digit becomes " ．"(decimal point) after 0 to 9.

5.2 Principle of operation
(1) The inputted voltage or current passes along a filter protection circuit, and becomes the DC voltage below
constant voltage. This voltage goes into an amplifier.
(2) The input is converted into the suitable voltage range in an amplifier. This voltage constitutes an input
of an A/D converter.
(3) The data converted into digital one by the A/D converter are sent to CPU. A/D converter has 16-bit resolution
and performs operation and conversion with 1MHz clock. Based on the scaling range that had this data set
up, it calculates within CPU. And the measurement value scaling by the LCD is displayed.
(4) The operation value and measurement value, which was set up beforehand, are compared, and the relay and LED
are operated.
(5) The front pushbutton switch makes each setting change.
(6) The value set up by the switch is saved at non-volatile memory (E2PROM). ROM has the capacity of 128×16 bits.

6. Inspection
6.1 Receiving inspection
In case you inspect at the time of receiving, please perform after reference the following.
(1) Structure
Inspection of an outline dimension, mounting dimension, and appearance.：Please perform with reference to
dimensional outline drawing.
(2) Performance
Please do a reserve energization (warm-up) for 15 minutes after a power supply apply. After that, please
conduct performance inspection. Performance inspection is performed with reference to 7.2 "calibration
method".
6.2 Periodic inspection
Please perform the following item if needed.
(1) Please check each set value.
(2) The accuracy test of indicated value.
An input tests indicated value as two to five points.
(3) Alarm output operation and setting accuracy.
The check with normal ON/OFF operation. The accuracy of operation value and reset value (dead band) is tested.
7. Check, calibration and maintenance
7.1 Check
It is not necessary to check especially every day. Please be periodically careful of the next item.
(1) It is checked whether a body and socket combination are normal (is a lock a totality?).
(2) It checks for the slack of wiring, and the slack of a captive screw.
(3) It will remove, if dust has adhered to the case.
7.2 Calibration
Calibration is performed in the calibration circuit of the right
figure.
(1) Please do a reserve energization (warm-up) for 15 minutes after
a power supply apply.
(2) When the input equivalent to the minimum display is applied,
in order that it may become the minimum display, set value
CBIAS is set up.
Next, when the input equivalent to the maximum display is applied,
in order that it may become the maximum display, it sets up
by set value CSPAN.
Calibration is finishing, if the above is checked again and
the display is correct. In addition, please refer to the
4.5 section "set value change mode" about setting of set
value CBIAS and CSPAN.
(3) Please perform the check of an operation value, a reset
value, and a dead band.
Note(13) It is the polarity of ( ) at the DC power supply case.

7.4 Countermeasures against troubles
As our principle, we recall product in question and repair it. If judged as product failure, have a contact with
us or sales agent for repairing work (Also have a contact with us or sales agent for specification change).
Product failure which we are not responsible for (When responsibility in manufacturing process is not recognized,
when product is disassembled/remodeled, in case of false operation by customer, etc.) is beyond our warranty.
