FUJI ELECTRIC M3LU (01) PDF Document

The package includes:

Signal conditioner (1)

Terminal block with CJC sensor (1)

I/O range and tag name label sheet (1)

Environmental temperature must be within -25 to +65°C (-13 to +149°F) with relative humidity within 0 to 95% RH in order to ensure adequate life span and operation for the FUJI ELECTRIC M3LU.

The FUJI ELECTRIC M3LU is designed to function as soon as power is supplied, however, a warm up for 10 minutes is required for satisfying complete performance described in the data sheet.

Before you remove the unit or mount it, turn off the power supply and input signal for safety.

The FUJI ELECTRIC M3LU is for indoor use.

When heavy dust or metal particles are present in the air, install the unit inside proper housing with sufficient ventilation.

Do not install the unit where it is subjected to continuous vibration. Do not subject the unit to physical impact.

Do not install cables (power supply, input and output) close to noise sources (relay drive cable, high frequency line, etc.).

Do not bind the unit’s cables together with cables where high noise levels are present. Do not install them in the same duct.

Hold at the top and bottom of the FUJI ELECTRIC M3LU as shown in the diagram and slide the housing cover gently to open until it hits the latching. Handle the cover carefully to protect internal components from damage. DO NOT pull beyond where the housing cover is latched. The plastic housing may be damaged.

When you need to separate the terminal blocks from the transmitter body for wiring, insert a minus driver between the terminal block and the housing body, pull up the driver and pull out the terminal block.

Set the FUJI ELECTRIC M3LU so that its DIN rail adaptor is at the bottom. Position the upper hook at the rear side of the unit on the DIN rail and push in the lower. When removing the unit, push down the DIN rail adaptor utilizing a minus screwdriver and pull.

For a thermocouple input, replace the Terminal Block (4-5-6) with the one connected with the CJC Sensor included in the package. Be careful not to separate the Sensor from the terminal block. If you did, connect the CJC leg marked with a white dot to the terminal 5 and the other leg to the terminal 6. The CJC Sensor is calibrated to a particular unit and not interchangeable with another. Match the Serial No. of the unit and the sensor.

Be aware that the AC power and DC power connect to different terminals.

Turn the SW3-8 OFF to enable the DIP SW (Field Configuration) mode as shown in Table 1.

Turn the SW3-8 ON to enable the PC Configuration mode as shown in Table 1.

Table 10: OUTPUT TYPE / PC CONFIG (SW1)

1) Terminal wiring: Check that all cables are correctly connected according to the connection diagram.

2) DIP SW setting: Check that the switches are set to appropriate positions.

3) Power input voltage: Check voltage across the terminal 10 – 12 (AC) or 11 – 12 (DC) with a multimeter.

4) Input: Check that the input signal is within 0-100% of full-scale.

If the thermocouple, RTD, potentiometer or their extension wires are broken, the output goes over 100% (below 0% with downscale protection) due to burnout function. Confirm the status indicator LED pattern and check leadwires in such a case.

5) Output: Check that the load resistance meets the described specifications.

1) Mount the DIP-SW-configured FUJI ELECTRIC M3LU on to a DIN rail.

2) Connect the FUJI ELECTRIC M3LU to a simulator and a multimeter and to a DC power source as shown in the connection diagram.

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

[Example] Setting both input and output to 1 – 5V DC

1) Run Mode: Confirm that the LD1 green light is blinking.

2) Input Configuration Mode: Press MODE button for longer than 5 seconds until the LD1 red light is ON and the LD2 red light is blinking.

3) 0% Input Ranging: Apply the desired minimum input level (e.g. 1V) from the simulator and push DOWN button until the LD1 flashes for approx. 2 sec. and then turns OFF. When you release the button, the LD1 is returned to ON. The flashing LD1 means that the value is stored in the memory. If the LED does not change, the entered level may be inappropriate: too small a span, or out of usable range (same for all steps).

4) 100% Input Ranging: Apply the desired maximum input level (e.g. 5V) from the simulator and push UP button until the LD1 flashes for approx. 2 sec. and then turns OFF. When you release the button, the LD1 is returned to ON.

5) Output Configuration Mode: Push MODE button and confirm that the LD3 red light instead of LD2 is blinking.

6) 0% Output Ranging: Increase or decrease the simulated input until the meter shows the desired minimum output level (e.g. 1V). Push DOWN button until the LD1 flashes for approx. 2 sec. and then turns OFF. When you release the button, the LD1 is returned to ON.

7) 100% Output Ranging: Increase or decrease the simulated input until the meter shows the desired maximum output level (e.g. 5V). Push UP button until the LD1 flashes for approx. 2 sec. and then turns OFF. When you release the button, the LD1 is returned to ON.

8) Run Mode: Programming complete, push MODE button and confirm that only the LD1 green light is blinking.

After the transmitter is installed and operational, fine zero and span tuning can be performed as explained below. Both zero and span are adjustable within ±15%.

1) Run Mode: Confirm that the LD1 green light is blinking.

2) Fine Zero Calibration Mode: Press MODE button for 1 or 2 seconds until the LD1 red light is ON and the LD2 green light is blinking.

3) Use UP (increase) and DOWN (decrease) buttons to adjust the output to 0%.

4) Fine Span Calibration Mode: Push MODE button and confirm that the LD3 green light instead of LD2 is blinking.

5) Use UP (increase) and DOWN (decrease) buttons to adjust the output to 100%.

6) Run Mode: Push MODE button and confirm that only the LD1 green light is blinking.

Note 1: Calibration steps can be skipped when not needed by repeating pushing MODE buttons.

Note 2: There is no stated order of setting 0% and 100% levels or no limitation of entering values for multiple times within one step of Calibration Mode. Signal level is stored each time the respective UP or DOWN button is pressed.
