1.0 GENERAL POINTS The instrument of the MP1200 series in the P6 type container (75mm depth) can be programmed with the following inputs: 4÷20mA, 0÷20mA, 0÷10V, thermocoupling J (Fe/Co) 0÷600°C, thermocoupling K (Cr/Al) 0÷1200°C, thermocoupling S (Pt/Pt10%Rh) 0÷1710°C or thermoresistence (PT100r: –40,0÷410,0°C, PT100e: –40÷800°C). The main characteristics are as follows: • two alarms with exchange relay output (3 if 220V power supply) • 18V not regulated for 2 or 3 wires transducer power supply • alarm programming and calibration by 6 key on instrument front panel for easy of use • 9999 point...

For thermocoupling connection use only compensated wire for the type of thermocouple in use. If shielded cable is used, connect the shield to ground at one end only. For thermoresistance connection pay attention to the line resistance: if too high there may be some errors in readout. Use the same kind of wire for the three connections. If shielded cable is used, connect the shield to ground at one end only.

2.0 INSTALLATION NOTES 2.1 INSTALLATION PROCEDURE 1- Execute the connections as indicated at 5, 6,7 pages 2- Switch on the instrument 3- Enter in the menu and set the requested scale (see table 2). For voltage or current inputs it is necessary to follow the indications written in 4, 5 and 6 steps. 4- Set the reading value that must coincide with the minimum input value (0 for key 0÷10V and 0÷20mA scales, 4 for 4÷20mA scale). For this setup use following the paragraph “How to operate”. 5- Set the reading value that must coincide with the full scale input value (10V for 0÷10V scale, 20mA for 4÷20mA...

MP1200 mect s.r.l. value coinsident with 10V at the input. By “d.p." key we can set up the decimal point. To configure the instrument with 4÷20mA input scale, it is necessary to set up in the ÷ menu “SCAL” item as 4-20. In this way, by "zero" key we can set up the reading value coincident with 4mA at the input and by “F.S." key we can set up the reading value coinsident with 20mA at the input. By “d.p." key we can set up the decimal point. To configure the instrument with 0÷20mA input scale, it is necessary to set up in the ÷ menu “SCAL” item as 0-20. In this way, by "zero" key we can set up...

4th OPERATION Confirm the programmed number by touching the 'zero' key. To program the decimal point observe the following indications. Al1 Al2 In1 In2 Touch the “5” key with the instrument in measuring mode. A decimal point will light up. In order to move this point touch the indicated key until the desired point is reached. 2.3 RECOVERY TARA FUNCTION Function enabled only for 0-10V and 4-20mA inputs. For “Recovery Tara” we mean a function that when in use zeroes the instrument readings. The Recovery Tara function with terminals 16 and 17 open is not in use and in these circumstances the instrument...

MP1200 mect s.r.l. 2.5 INSTRUMENT SET UP By using a hidden menu which is accessed by pushing together the two keys SET1 and F.S., it is possible to programme certain items of secondary importance which are protected by a password code and which can be useful for certain display values or for alarm functions. These setups are explained in the following table. IMPORTANT For the programming of the instrument display parameters there are four codes: Figure A ISI, ISL, FSI, and FSL. These menu items allow the setup of the co-ordinates which process the instrument readings. The first co-ordinate is...
