1.0 IN GENERAL The MPPV340 model (strain gauge input) is an instrument with a 16 bit analogue to digital converter; it is made in 48x96 standard body. The MPPV model can be requested specifying the sensibility range: 1 mV/V (0.5 ÷1.5 mV/V) 1.5 mV/V (1 ÷ 1.5 mV/V) 2 mV/V (1.5 ÷ 2.5 mV/V) 3 mV/V (2.5 ÷ 3.5 mV/V) 10 mV/V (9 ÷ 11 mV/V) The MPPV340 model have interesting features as: • 4 ½ digit display ( ± 19999 digits ); • set-up of any reading value with any input value in the requested range; • maximum or minimum peak-hold; • programmable digital filter; • display reset function. • possibility...

KEYBOARD DESCRIPTION : alarm set-up : allows readout zeroing, or, when in menu program, fast exit. : increments blinking digit in menu or decimal point set-up ^™ : shifts blinking digit in menu or prints readout : readout zero set up ("offs" item in the menu) : readout full scale set-up or enter in menu (enter)

LEDS DESCRIPTION TERMINAL BOARD DESCRIPTION - analogue reference - signal input - power supply for transducer - analogue outputs (if requested) - Hold : short-circuiting terminals 10/12 stores observed - Display reset. Terminals 11/12 open: the reading are the same as the programming values. Terminals 11/12 closed: at the moment the terminals are short-circuited the display becomes zeroed (display reset) -instrument power supply

1.6 CONNECTIONS FOR 8 STANDARD OR OPTO-ISOLATED STATIC Static output can be requested as follows (with order code): 1) STN/STNO: Standard or opto-isolated static NPN output open collector 2) STP/STPO: Standard or opto-isolated static PNP output open collector

Press + 1 I keys to enter menu. To reach a menu item, use the and the key as shown in the menu flow for base instrument and base + option instrument. To change a digit, use the H'p' key to increment the blinking digit and the IB key to shift the blinking digit and confirm by * ~ key. To select an item use the key and confirm by the key. To exit menu, use the key: me modified parameters are stored.

2.0 INSTALLATION NOTES 2.1 SIMPLIFIED INSTALLATION PROCEDURE 1- Connect the instrument as follows: pag 6 – base instrument wiring diagram pag 7, 8 – alarm wiring diagram (if requested). 2- Use sensibility or sample weight calibrating in according with the following paragraphs. 2.2 CALIBRATING THE INSTRUMENT WITH CELL SENSIBILITY To follow this procedure you must know the cell sensibility (see it in the calibrating certificate). Suppose to have a load cell with a sensibility of 1.9856 mV/V with a full scale of 150 Kg. To calibrate the instrument do the following: 1. Power on 2. 3. 4. 5. 6. 7....

With the key it is possible to set up the alarm values To set up the alarm values use the following table. For further information about the alarm functions, see “Alarm” paragraph.

MPPV340 M6 2.3 CALIBRATING THE INSTRUMENT WITH SAMPLE WEIGHT OR 5° WIRE If you don’t know the sensitivity of the cell, you can calibrate the instrument with a sample weight or the cell’s 5° wire. If you have a cell with about 2mV/V sensitivity and use a 1.5678Kg (or 5° wire) weight to calibrate the instrument. To calibrate the instrument do the following: 1. Power on 2. Setup the decimal point position to 0.0000 by d.p. 3. Set SEL.C = PESO 4. Exit the program menu and perform a reset display function...
