MPT390 M6 1.0 GENERAL POINTS The instruments of the family " MPT/390/M6" represent a series of " Single Loop" microprocessor temperature regulators in the standard 48x96 dimensions (120 mm. depth.) The complete version of the MPT/390/M6 instrument has the following technical characteristics: 1- Input from Thermoresistance PT100 ( scale -40.0 ÷ 200.0°C or -40 ÷ 800°C), or from thermocoupling Fe/CO (0÷600°C) and Cr/Al (0÷1200°C) and Pt-Pt/Rh (0 ÷ 1710°C), or from voltage ( 0÷ 10 V ) and current (0/4 ÷ 20 mA) selectable from the keyboard. 2- Two display to see Set-Point and Process Value and 6...

DESCRIPTION OF THE TERMINAL BOARD Thermocoupling sensor principal exchange relay ( NO contact). principal exchange relay ( COM contact). principal exchange relay ( NC contact). contact NO of alarm relay 1 (if requested) contact NO of alarm relay 2 (if requested) static output for main operations (terminal 8: power supply, for exsternal static relay, of around 16 Vdc). load control break HB (if requested) instrument power supply. Between terminals 13 and 15 power at 90/260 Vac/Vdc, or 12/30Vac/Vdc if requested. analogue outputs (if requested). serial output connections (if requested)....

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. THERMOCOUPLING CONNECTIONS Thermocouplings must be isolated. only compensated wire for the type If shielded cable is used, connect CURRENT INPUT CONNECTIONS

STATIC OUTPUTS CONNECTIONS V+ Be careful: this output is not isolated and may be used for an external solid state relay with double isolation between instrument and power line. SERVOMOTOR CONNECTIONS Valve closing Valve supply Servomotor Valve opening SERIAL OUTPUTS AND ANALOGUE OUTPUTS CONNECTIONS See dedicated paragraphs. ME4014_15 10/11

MPT390 M6 2.0 INSTALLATION NOTES 1. Copy the connection schemes on pages 6, 7 and 8 taking into account the following points: a- the instrument can operate with analogue inputs or temperature sensors of both thermoresistance and thermocoupling types. Only one of this sensors can be connected (attach the connection only for the chosen sensor, leaving free the other connections.). b- the connector diagram shows all the possible options that the instrument may have; if certain options are not required then the relative connections are not necessary. 2. Follow the instructions of the paragraph:...
