1. Product explanatory
1.1 Outline
This product is the alarm setter of small plug-in structure.
As input the two DC signal, to measure the deviation and the deviation of each individual input between the
input, by comparing it with the pre-set value, and outputs the excess or deficiency in the contact signal.
Since this product is software compatible form, it can be set in the real scale of the full scale of input
in accordance with the process amount. In addition, each set value (operating value, the moving average constant,such as contact delay) can also be freely set change.
Input (real scale) and, each set value is displayed in 4-digit LCD (backlit).
1.2 Features● Setting accuracy is ±0.5％ (％ for input span). Display accuracy is ±0.5％ ±1digit (％ for input span).
● Withstand voltage AC2000V design. (Between input, output, auxiliary supply, case.)● Display and setting of real scale by LCD can hold in front key switch. They respond to a scaling change too.
● Setting by non-volatile RAM, it will be a power outage guarantee.
● The reduction of internal heat generation, has improved the reliability.
● Backlight is lit at the time of key switch operation. Backlight to key switch operation end after 30 seconds
will turn off.

6.4 Precaution in the establishment● Mounting state
Especially restriction does not have a mounting position. Mounting instruction can select 35mm width DIN rail
mounting and screw mounting. Please get mounting with M4 screw. (But a screw is not attached. And give a binding
fast torque of a screw as 1.08 to 1.47N･m)
Should establish of side-by-side mutual mount space 5mm over. Top and bottom space considers wiring and spaceradiation of heat, and please establishes space more than 100mm.
● Electric wiring state.
Please separate wiring of an input and an output and carry out consideration to a noise. And, please separate
from a wire with the power line used as the source of a noise and steep voltage, and current as much as possible.
Especially, please use shielding wire in the remarkable environment of a noise.
● Environment condition.
(1) Ambient air temperature, humidity range.
Please give the ambient temperature and humidity under each device operation as the following range.
Temperature：0 to 55℃，Humidity：30 to 85％ RH (Non condensing)(2) Environment ambient atmosphere.
The case has sealing construction. However, when you use it in an environment with much dust, please be
careful. And, please consult on the occasion of use in the environment of corrosive gas (hydrogen sulfide(H2S) chlorine (Cl)).

7.1 Acceptance inspection
When they put acceptance inspection into effect, put below into effect after reference.
(1) Construction
Dimension, installation dimensions and check of outward appearance refers to dimensions diagram.
(2) Performance
They put 15 minutes warm-up into effect after auxiliary supply input applied and carry out performance
inspection.
Performance inspection refers to a calibration way of Sub-Section 8.2 and come into effect.
7.2 Periodical inspection
Please carry out the following item if needed.
(1) Each set value is checked.
(2) The accuracy test of indicated value：An input is made into two to five points, and tests indicated value.
(3) Alarm output operation and setting accuracy：It tests that ON/OFF operation is normal. And, the accuracy of an
operating value and a resetting value (dead band) is tested.

8.2 Principle
DC input signal of 2 is select in turn by multi plectra and they are input into pulse width modulation circuit.
They are have reference clock the signaling that was set up as pulse width modulation counting and they read it
and they are crowd by CPU. They detect input interval deviation of signaling of 2 crowd in a reading in CPU. They
let armature relay and LED work by comparing with operating value. Input signal is indicate by liquid crystal display
department 4 digit in true scale. Operating value and a delay timer can establish it in switch.

9. Maintenance and calibration
9.1 Inspection
They especially do not need to do inspection every day. Pay attention to a following thing regularly.
（1）Is there not main frame and socket association abnormality ? (Is lock perfection ?)（2）Is there not electric wiring and looseness of installation screw ?
（3）When they take away it dust stick to case.
9.2 Calibration
Proofreading hold in calibration circuit of diagram.
(1) They set up as auxiliary supply after applied 15 minutes
warm-up.

Power supply(７ )(2) When they set up as the input that is equivalent tominimum display applied, they establish minimum display
and setting value CBIS1 / CBIS2 that it seem to become
once again.
(3) When they set up as the input that is equivalent tomaximum display applied, they establish maximum display
and setting value CSPN1 / CSPN2 that it seem to become
once again.
They identify that upper account of it once again andthey are calibration closing if display fit each other.
Refer to calibration setting of Sub-Section 5.5 still
about setting of setting value CBIS1 / CBIS2 and CSPN1/ CSPN2.

9.4 Maintenance(1) Please do not make a wiring change of the input and auxiliary supply in an energization.
(2) In case you check in an energization, a human body should touch neither an input nor a control auxiliary supply
terminal.
(3) Please check a connection diagram, in case you check the voltage of input, and auxiliary supply.
(4) If a name plate is wiped with solvents (an alcohol, etc.), a display way may disappear. Please give care asa wiping with dry cloth grade in the dry cloth.
9.5 Storage(1) Please avoid storage in the next space. Low temperature, high temperature, high humidity, and sunny place.
(2) The aluminum electrolytic capacitor is used for a product. Please do the energization of the power supply within
one year after shipment.
9.6 Countermeasures against troubles
As our principle, we recall product in question and repair it. If judged as product failure, have a contact withus 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.
