1.0 OVERVIEW The MPCT30 P6 model has 5 main programmable functions: RPM meter, frequency meter, hourly production meter, timer, and uni-directional pulse counter. Each one of these five functions is independent and they can’t be used at the same time. Main characteristics are: • count memory at the switching off (you can exclude this function from the menu). • four digits for counting. • NPN or PNP inputs (open collector or passive pull-up) or not amplified proximity (configured by jumpers or terminal connections) • programmable multiplying and dividing factor from 1 to 9999 (pulse counter,...

BASIC TERMINAL BOARD DESCRIPTION - exchange relay output (AL1: 1 = Com, 2 = NC, 3 = NO) - pull-up resistor for counting input - ground - counting input, start for chronometer function. - transducer power supply (16Vdc). On request 5V. - “hold” or “stop” for timer - external reset - instrument power supply (if Vcc or Vpt is not important the polarity). Verify the instrument’s label to understand the power supply value to give.

1.10 PRINTED CIRCUIT BOARD (PCB) CONFIGURATION The “hold” and “reset” configuration. Open the instrument to configure the “Hold” and “Reset” (NPN or PNP) inputs. To open the instrument use a screw-driver to lever on the long part of the keyboard and on the side hooks and extract the instrument from the front. The “Hold/Stop”, “Start”, and “Reset” inputs are in NPN configuration. To set up the “Reset”, “Hold/Stop” and “Start” inputs as PNP version, move the JP12 and JP13 jumpers in 1-2 position. Mechanical contact input configuration Open the instrument as over written and link the JP11...

2.0 REVOLUTION COUNTER, FREQUENCY METER AND HOURLY PRODUCTION INSTALLATION REMARKS 2.1 INSTALLATION PROCEDURE 1) Make connections as indicated at pages: 7, 8 and 9 HOLD terminal connections: when it works, it stops the visualization and the acquisition of new input signals. To modify the “hold” input for a PNP input look paragraph “PCB configuration” 2) Switch the unit on. 3) Program the functions based on the indications in the following table: Table 3 n°seq. ° Appears on the display PASS Ou InP CPAS AbtA dEF tYPE rPn Touch the “prog.” key to get into the programming menu In this phase the...

The parameter to be measured is the speed, in mt/sec., of toothed belt by reading the rotating speed of the driving shaft. Four notches can be identified on the shaft and the belt advances by 0.55 mt for one revolution of the shaft. To get the requested visualisation, you have to multiply the reading revolution/minute (RPM) by 0.55. To visualize the...
