1.0 GENERAL POINTS The MPM series instrument in the P6 housing (depth 75mm) has 2 analogue inputs and can show one input or the sum, differance, product or ratio of the two. The instrument can be ordered for 2 current (0÷20mA or 4÷20mA ) or voltage (0÷10V) inputs. The main characteristics are as follows: • two alarms with exchange relay output (3 if 220V power supply) that can be assigned to display, channel 1, channel 2, sum, difference, product or ratio. • 16V not regulated for 2 or 3 wire transducer power supply • alarm programming and calibration by 6 key on instrument front panel for...

TERMINAL BOARD DESCRIPTION serial outputs - transducer power supply (16V) - instrument power supply (Vcc, Vpt, 24Vac, 90-=-260Vac). DC power supply, terminal 13 is positive and terminal 15 is negative. - analogue output (if requested) - Hold: shortcircuiting terminals 16 and 18 will - Recovery tara: 1) Terminals 16-17 open: the reading is the same as the programmed values 2) Terminals 16-17 closed: at the moment the terminals become shortcircuited the display is zeroed (rec.tara) If requested serial output (the "hold" and "Rec. tara" functions is not available): Terminal 16: see paragraph...

I ^+2 = numer relevant to use table keys and reach the program If you want to reach an item, use the To skip into the item press If you want to change a number, use the I_3 key to increment the blinking digit, and the I ^ 1 key to shift the blinking digit. To exit from the menu, press modified parameters will be stored.

analog output serial output 1- Execute the connections as indicated at 6, 7, 8 pages 3- Get into the programming menu to set the type of visualization required (by the "SCAL" menu item) and the set up of the two inputs (ISI1, ISL1, FSI1, FSL1 e 4- The "zero" key is enabled just for the visualization of the single input (canl and can2). Using the "zero" key it is possible to set the reading value which must be the same of the minimum input (0 for the 0-10V and 0-20mA scales, 4 for the 4- 20mA scale to change this value see paragraph "Instrument configuration".

MPM P6 mect s.r.l. 5- The “F.S.” key is enabled just for the visualization of the single inputs (cAn1 and cAn2). Using this key it is possible to set the reading value which must be the same of the input “fondo scala” (10V for the 0-10V scale, 20mA for the 0-20mA and 4-20mA scales to change this value see paragraph “Instrument configuration”). 6- Use the key to set up the decimal point as required. key to set up alarm value 2 8- Use the 9- The instrument is now ready for use. 10- For automatic zeroing check the recovery Tara function. 11- To install other input parameters or alarms see the...

mect s.r.l. 2nd OPERATION Touch the “4” key to move the flashing digit to the right. 3rd OPERATION Touch the “5” key to increase the flashing number. 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...

MPM P6 mect s.r.l. Let us assume that the instrument, linked to a transducer, indicates a 100kg number. Shutting down the connection between terminals 16 and 17 will zero the instrument reading , thus rendering the indications negative for weight values that are less than 100 Kg and positive for values that are greater than 100 Kg. N.B. The recovery tara function is used when it is necessary to zero the instrument reading continuously as the data contained in the instrument memory will not be retained after instrument switch off. To retain in the permanent memory the zeroed data you should...
