  • Page 5: Introduction

    INTRODUCTION MT03L converters are indicators for level measurement applications. The electronic circuit is based on the most advanced technology in digital signal processing, in order to obtain accurate and reliable measurements. The equipment provides the following features (depending on the model): •...
  • Page 6: Electrical Connection

    Electrical connection The connection of the equipment is via plug-in connectors, polarized to avoid mistakes when plugged in. The connectors have screw terminals, as per VDE standards, to accept cables with section of 1.5 mm The pictures of the connections in this manual are always looking at the equipment from the back.
  • Page 7: Resistance Input Wiring

    Before starting the wiring of the instrument, check that the supply voltage available is the same as marked on the label of the converter. Terminal Power supply AC Power supply DC Phase Neutral In case of DC power supply, the equipment is provided by a diode bridge that allows connecting it regardless of the polarity.
  • Page 8: Analog Output Wiring

    Terminal mA (positive, power supply for a passive device) mA input mA (negative, input from an active device) This input is compatible with any flow rate transmitter that provides a 4-20 mA output. The impedance is 120 Ω. The input has a protection in order to limit the voltage applied to the circuit.
  • Page 9: Relay Output Wiring

    Terminal mA (positive, active output) mA (negative, passive output) The analog output is galvanically isolated. It can be either active (which means that the receiving device must be passive) or passive (which means that the receiver must supply the power for the current loop). It is recommended to use a receptor with an input resistance of less than 700 Ω...

The status of the relay contacts corresponds to the relay at rest.
  • Page 11: Operation

    OPERATION The MT03L converters have a graphic LCD and a keyboard with 4 push buttons. The following figure shows the functionality of the converter keys. (Down / Left) To change to the digit on the left. Into the menu, to scroll down. (Up) To increase the digit.
  • Page 12: Main Menu

    MAIN MENU To access the main menu of the converter, press the key (Enter). The following screen appears: Number of menu items Selected item The "Installation" option allows the basic configuration of the instrument, as explained in Chapter 6 of this manual. The "Programming"...
  • Page 13 To change the access password of the programming menu, select "Programming" in the main menu and then "Password". When the "Password" option is selected, a screen that indicates the password status for this menu appears. Selecting “Activate”, the screen to enter the new password appears.
  • Page 14: Installation Parameters

    If the password needs to be changed or disabled, the procedure is the same. Once entered the "Password" menu, the following screen appears: If Change is selected, the equipment will ask for a password again. If Disable is selected, the following message will appear: INSTALLATION PARAMETERS Power on the electronic converter with the voltage indicated on the label.
  • Page 15: Language

    Language The language in which all the menus will be displayed can be chosen. Input In this screen the type of signal from the sensor connected to the MT03L can be chosen. Resistance input is compatible with level transmitters of series LE and transmitters LTE of series LT, as well as with other level transmitters based on resistance variation.
  • Page 16: Distance Adjustment

    To perform the capture options, set the level meter at the lower limit position (e.g. float in its lowest position) and select the "Capture inf." with the key “Enter”. The following confirmation screen appears. Selecting Yes, the device reads the input signal and sets the lower limit level. The same procedure can be done with the capture of top level, placing the level meter at the upper limit position.
  • Page 17: Programming Parameters

    If 4 mA is selected, pressing the key (Enter) toggles between 4, 8, 12, 16 and 20 mA, allowing to check the adjustment of the analog output. Finally, in the last row, the selected input type and a number that is related to the value of that input is shown.
  • Page 18: Language

    Language You can choose the language in which all the menus will be displayed. Units In this screen the units for the level indication can be chosen. Decimals In this screen the number of decimals for the level indication can be selected. To select the number of decimals it must be taken into account that the instrument has 5 digits for level rate indication.
  • Page 19: Damping

    Damping The MT03L converter has an adaptive filter (damping) to provide stable level and analog output readings in the presence of continuous level fluctuations. The configuration of this filter can be very useful in the cases where the level readings have some instability (due to for example waves in the tank).
  • Page 20: 7.5.1.2 No Action

    Example 1 If the activation point is programmed to 100 cm and the deactivation point is programmed to 90 cm, when the level is zero the output will be deactivated. When the level reaches a value of 100 cm the output will be activated until the level falls below 90 cm. Example 2 If we program an activation point of 90 cm and a deactivation point of 100 cm, when the level is zero the output will be activated.
  • Page 21: 7.5.2.1 Programming Of The 4-20 Ma Output

    7.5.2.1 Programming of the 4-20 mA output Level values equivalent to each current are entered directly. Programming a level value for 20 mA higher than the one for 4 mA, the loop current changes from 4 to 20 mA as the level increases. Otherwise, programming a level value for 20 mA lower than the one for 4 mA, the current loop will change from 20 to 4 mA as the level increases.
