1. Outline on the product
This product is a small plug-in structure alarm setter.
This product takes a DC voltage or DC current signal as input, compares it with the preset operating point,
and outputs the excess or deficiency as a contact signal.
The full scale of the input can be arbitrarily set on the actual scale according to the process amount, and
each set value (operating value, contact delay, etc.) can also be set freely.
This product is used in combination with a mounting base (FWBA-□, hardware model B).
1.1 Features of product
 The setting accuracy is ±0.1％ (％ of input span).
The display accuracy is ±0.1％ ±1 digit (％ of input span).
(±0.2％ for voltage input less than 1V)
 Various settings can be changed with the front switch.
 The measured value (real scale) and various set values can be confirmed on the LCD.
 The backlight lights when a key is pressed.
The backlight lights off 30 seconds after the key operation is completed.
 The set value is guaranteed by the non-volatile memory E2PROM even during a power failure.
 The pre-alarm function displays the progress of the contact delay time by blinking the monitor lamp.
(Pre-alarm ON/OFF can be selected by setting)

2.3 About of auxiliary supply
By applying auxiliary power to the power supply (AUX. SUPPLY) terminal of mounting base, power is supplied
to each unit.
When mounting base has unit individual power switch.
Please insert this product into the mounting base and tighten the screw to fix the main body.
An auxiliary power is supplied. Also, when removing, by loosening the screw, supply of auxiliary power
supply is cut off. (When the auxiliary power is supplied, the power LED of this product lights on, and it
lights off when it is shut off.)
Without individual unit power supply switch.
Regardless of the tightening of the fixing screw on the main unit, auxiliary power is supplied.
2.4 Cautions on installation
● Wiring state
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.
● Environmental condition
(1) Ambient temperature and humidity range
The ambient temperature and humidity during the operation of each equipment should be in the
following range.
Temperature: -10 to 55 ℃, humidity: 5 to 90％ RH (Non condensing)
(2) Ambient atmosphere
Please be careful when using in dusty environments.
Also, please consult us when using under corrosive gas [hydrogen sulfide (H2S), chlorine (Cl), etc.]
environment.
2.5 LCD viewing angle
Mount the LCD to obtain an optimum angle,
since the contrast changes according to
the monitoring angle.
If the unit has an individual power switch, auxiliary power will not be supplied to this product
unless the fixing screws are securely tightened. Be sure to tighten the fixing screw.
Tighten the fixing screw to supply auxiliary
power supply. (Power LED lights on)
Loosening the fixing screw will shut off the
auxiliary power supply. (Power LED lights off)

3.6 Calibration
Because this product is adjusted beforehand, there is no necessity for calibration.
However, if the operating point of an alarm output shifts, please adjust in the next way.
(1) After turning on the auxiliary power, perform preliminary energization for 15 minutes.
(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 "setting 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.
4. Block-diagram and principle of operation
4.1 Block-diagram
4.2 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 key 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.

5.4 Pre-alarm function
A monitor lamp is blinked among contact delay time until excitation of a relay after operation value
detection. Blinking of a monitor lamp will be gradually fast, and when the point of contact delay time
passes, a monitor lamp is lights up.
If contact delay time setting is made into 0 second, a pre-alarm function constitutes OFF.

・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.
・When changing the scaling, set the operation values 1 to 4 within the measurement display range (see below).
Even if the output mode is set to OFF, keep it within the measurement display range.
・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.
Becomes the L detected at the input 0mA,
can also be used as a disconnection
detection.
・After setting change, in case a set value combination error occurs, it becomes a setting error display.
Please push the key and set up the right set value (in set value change mode).

● 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.
