caustic soda may attach to the unit, or where such materials are present in the air. – Where the unit is subject to continuous vibration or physical impact. – Where there are high-voltage lines, high-voltage equipments, power lines, power equipments, equipments with trans-
mission unit such like a ham radio equipment, or equipments generating large switching surges around the unit.

3.4 WIRING

•In order to prevent potential electric shock, wire the unit after turning off the power supply and making sure that the power is not supplied to the cable.
•Be sure to conrm the name and polarity of each terminal before wiring to the Euro type connector terminal blocks.
•Do not connect anything to unused terminals.

3.5 HANDLING CAUTIONS

•The unit 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.
•Use the unit within the noted supply power voltage and rated load.
•The last measured values are held in mode transition. Take this into consideration when conguring the control system.
•Clean the surface of the unit with wet soft cloth. Do not use organic solvent such like benzine, thinner and alcohol. Doing
so may result in deformation or discoloration of the unit.
•When abnormality is found such like smokes, unusual smell and abnormal noises coming from the unit, immediately cut the power supply and stop using it.

4. FEATURES AND PREPARATION PROCEDURE OF M3LU2

4.1 FEATURES OF M3LU2

The M3LU2 is a eld congurable signal transmitter using a simulator and an indicator, without a PC or a dedicated setting unit. For instance, select an input type and range with the DIP switches on the unit to set input. Then apply a desired minimum or maximum input from the simulator and press a front button to memorize the value as minimum or maximum value. Easy and reasonable M-System’s one-step calibration (hereafter called ‘One-Step Cal’) realizes automatic I/O ranging and cali­bration only by pressing a button once.

4.2 PREPARATION PROCEDURE

Before using the unit, perform the calibration according the following ow. The procedure depends on the conguration options or modes.
•Two conguration modes are available with the model M3LU2-x/A, eld conguration using the DIP SW / control buttons (hereafter called ‘DIP SW conguration’) and the PC conguration.
•The model M3LU2-x/B is for the DIP SW conguration only.

7. DIP SWITCH CONFIGURATION

SW1
This chapter describes the conguration of the I/O specications and functions using the DIP switches and the JP2. For the PC conguration, some DIP switch settings are necessary.

7.1 DIFFERENCE BETWEEN DIP SW CONFIGURATION AND PC CONFIGURATION

The following table shows the difference between the DIP SW conguration and PC conguration.
CONFIGURATION ITEM DIP SW CONFIGURATION PC CONFIGURATION
Conguration mode SW3-8 OFF SW3-8 ON
JP2 for input type Required Required
DIP SW for input Required ----
Output type Required Required for SW1-1 through 1-4
Front control button lock As necessary As necessary

7.2 DIP SWITCH SELECTION PER I/O SPECIFICATION AND FUNCTION

Congure the DIP switches and JP2 according to your I/O specications and functions. The unit reads the DIP-switch-calibrated conguration only once after the power supply is turned on. Set the switches with the power supply removed. Some tools are needed to set the DIP switches and JP2.
•Set the switches and JP2 with the power supply removed.
•Use tweezers or longnose pliers to switch the JP2.
•Use a minus screwdriver with the blade edge 0.8 mm (0.03”) to set the DIP switches.
•Do not touch other electronic components except for the JP2 and DIP switches.
