1. Outline on the productThis 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, andeach 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.

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 themaximum 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.

4.2 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.

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.

● 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.
