The DIP switch setting is required to select output types before setting a precise output range using the PC configurator

software.

For detailed information on the configuration and calibration, refer to the instruction manual.

ADJUSTING DETECTING LEVEL

A specific sensitivity scale is applied according to the pulse amplitude by setting up the DIP switch and PC Configurator

Software (model: M3CFG). The scaled input voltage is then compared to the detecting level at -2.00 through +4.00 V.

For open collector input, be sure to adjust the voltage to following values if it has been changed for other input types.

Detecting level:

0.6 V (4 V excitation)

2 V (8 V / 12 V excitation)

With DC coupling, the scaled maximum input voltage level voltage must be higher than and the scaled minimum input voltage

level must be lower than the detecting level so that the pulse state is accurately detected.

Choose the noise filter type appropriate for the selected frequency range to ensure the described accuracy.

Time constant is set to 50 msec. with the large noise filter setting and to 10 msec. with the small noise filter setting.
