USER'S MANUAL

1.0 OVERVIEW The MPCT20 M1 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. The instruments have two relay alarms. Main characteristics are: • count memory for almost ten years (yuo can exclude this function fron the menu) • five digits for counting and five digits for Set-Point. • NPN or PNP inputs (open collector or passive pull-up) or not amplified proximity (configured by jumpers or terminal connections) • two contact relay alarm outputs (5A switch) or...

1.10 PRINTED CIRCUIT BOARD (PCB) CONFIGURATION Open the instrument to configure the main input (standard or mechanical contact) and the “Hold” and “Reset” (NPN and PNP) inputs. To open the instrument use a screw-driver to take off the back of the body of the instrument and extract the instrument from the back. To set up the input circuit as mechanical contact link by the jumper the JP1 configuration. To set up the “Reset” and “Hold” inputs as PNP version, move the JP4 and JP5 jumpers in 1-2 position.

MPCT20 M1 mect s.r.l. 2.2 "nUn" and “dEno” FUNCTION There are two menu items that allow to modify the displayed value by a constant factor. The “nUn” item allows to program a multiply factor in the range 1 ÷65535, and the “dEno” item allows to program a divide factor in the range 1 ÷65535. The constant factor will be: nUn readout on the display = _________ * X dEno Where: X = “RPM measured” if the instrument is set up in revolution counter X = “Pr.h measured” if the instrument is set up in hourly production X = “pulses read at the input” if the instrument is set up in pulse counter For a...

The parameter to be measured is the hourly production of a toothed belt moving bottles. Each toothed represent a row of ten bottles. To get the requested visualisation, you have to multiply 10 with the hourly production meter reading (Pr.h). To visualize the hourly production meter reading you must set up in the menu item “n.riF” = 1 (notches for revolution). To correct the visualisation by a 10 increasing factor, you have to set up “nUn” = 10 and “dEno” = 1. Infact we know this...
