I/O RANGING & FINE ADJUSTMENTS

After the DIP SW setting is complete, set up the precise

input and output range using the front control buttons. Be

sure that the front control button function is enabled with

theDIPswitchsetting.

The front LEDs’ colors and ashing patterns help you to

easily identify the transmitter’s status and conﬁrm the set-

up actions in each step of Calibration Modes. Please read

the following explanations referring to “Calibration Flow

Chart”inPage6.

■ PREPARATION (e.g. M3LPA2-R4/A, DC powered type)

1) Mount the DIP-SW-congured M3LPA2 on to a DIN

rail.

2) Connect the M3LPA2 to a simulator and a multimeter

andtoaDCpowersourceasshownbelow.

3) Turn the power supply on and wait for 10 minutes.

■ INPUT & OUTPUT RANGING

[Example] Setting input to 10 – 80 Hz (DIP SW range 0

–100Hz),outputto1–5VDC(DIPSWrange±10V).

When you set 0% or 100% input/output ranges,

keep pressing UP or DOWN button until the

LD1 flashes for approx. 5 seconds and turns off,

which indicates the setup is complete.

When you release the button, the LD1 is returned

to ON.

If the LED does not change, the entered level may

be inappropriate: e.g. out of usable range.

*For the model M3LPA2-x/A, the green LED is blinking.

For the model M3LPA2-x/B, the green LED turns on.

In order to change the threshold, apply simulated

100% input signal and push UP (increase) or DOWN

(decrease) buttons until the output meter shows

100% output signal as in the example below.

When polarity is set to Bipolor, because the internal

threshold level is fixed to 0V, the threshold calibration

mode does not function.

[Example]

Input range: 0 to 100 Hz

Output range: -10 to +10V

Apply 100 Hz and the output meters must show +10V.

Once the transmitter

enters the fine zero

calibration mode,

the output goes to

preadjusted 0%

value regardless

of the present input

signal.

Once the transmitter

enters the fine span

calibration mode,

the output goes to

preadjusted 100%

value regardless

of the present input

signal.

ADJUSTING DETECTING LEVEL BY USING PC CONFIGURATOR SOFTWARE

PC Conﬁgurator Software (model: M3LPACFG) can be used to adjust the detecting level with Option /A type. Appropriate

detectinglevelisdeterminedaccordingtotheowchartbelow(voltagepulseor2-wirecurrentpulseinputonly).

START

Confirm the Sensitivity Scale in Table 14

below.

Assign the value in the following equation.

Detecting Level (V)*

DC Offset (V)*

¥ Sensitivity Scale

Set DIP SW to the DC coupling and adjust

the detecting level to the value calculated

above.

Set to 4V when the calculation result is

higher than 4V, set to -2V when it is lower

than -2V.

Set DIP SW to the capacitor

coupling and adjust the

detecting level to 0V.

DC coupled input sensing?

Yes

*1.

*2.

Rounded off to one decimal place.

Divide a current input (mA) by 10 and convert it into voltage (V).

e.g. Offset = 10mA --> 10mA x 1/10 = 1V

A speciﬁc sensitivity scale is applied according to the pulse

tion Software. The scaled input voltage is then compared to

thedetectinglevelat-2.00through+4.00V.

WithDCcoupling,thescaledmaximuminputvoltagelevel

voltage must be higher than and the scaled minimum input

voltage level must be lower than the detecting level so that

the pulse state is accurately detected.
