    PRECAUTIONS READ THIS MANUAL BEFORE using or servicing the instrument. FOLLOW these instructions carefully. KEEP this manual for future use. CAUTION The purpose of this manual is to make the operator aware of the texts and explanatory figures, the basic requirements and criteria for the installation and correct use of the instrument.

  • Page 5: Introduction

    2 tensioning screws supplied. The MCT 1302 uses the RS232 serial port with ASCII protocols, to be connected to the PC, PLC and re- mote units with a maximum distance of 15m beyond which it is necessary to use the RS422/RS485 serial output that allows the connection also with MODBUS RTU protocol up to 32 addressable instruments.

  • Page 10 ELECTRICAL INSTALLATION The MCT 1302 instrument uses for the electrical connection of the 3.81 mm removable screw terminal blocks. The load cell cable must be shielded and channeled away from power cables to avoid elec- tromagnetic interference. The field wiring of the instrument must be suitable for the environment in which it will be used and must comply with all national regulations.

  • Page 12 LOGIC INPUTS The logic inputs are insulated from the instrument through optocouplers. The connection cables of the logic inputs must not be channeled with power cables. Use a shorter connection cable as possible. To activate a logic input, it must be brought to the positive of a 24Vdc power supply while the common item must be connected to its negative.
  • Page 13 If the cable has more conductors than those used, connect the free wires to the screen. The serial connection cable must have a maximum length of 100 meters. The cable must not be channeled with other cables, but must possibly follow its own path MCT 1302 20 S I/O+ External...
  • Page 14 The cable must not be channeled with other cables (i.e. outputs connected to contactors or power ca- bles), but must possibly follow its own path.

  • Page 15 USB DEVICE (SPECIFICATION 2.0 COMPLIANT, FULL-SPEED 12 MBPS) Use this communication port to directly interface a PC via a USB port. Use a standard USB cable for the connection. To connect the instrument via the USB device port, the appropriate driver for the operating system used must be installed on the PC.
  • Page 16 By putting several MCT 1302 instruments in series, the MASTER will be connected to the IN connector of the first MCT 1302 whose OUT connector will connect to the IN connector of the next, etc. Refer to the previous page for connection notes and warnings.
  • Page 17 For reliable operation of the fieldbus, a line terminator should be used at both ends. In case of multiple MCT 1302 instruments, use the line end only on an instrument. For the setup of the board, the GSD file (hms_1810.gsd) is available and must be installed in the master.

  • Page 47 CALIBRATION WITH SAMPLE WEIGHTS The calibration method described here must be carried out using sample weights and/or product pre- weighed on a sample scale. Always perform zero calibration before proceeding with the full scale calibration. CAUTION! If the instrument is switched off without leaving the set-up menu, the programmed settings are not stored.
  • Page 48 TABLE CALIBRATION It allows you to manually program up to 5 calibration points, in addition to the zero value. The values correspond to those determined by the linearization procedure with sample weights. In this way, it is possible to display the values determined automatically with this procedure, or modify and program them according to preset values.
