FURTHER INFORMATION

On the counter is possible to set: 2 set-points,3 working modes on the OUT 1, four working modes for the OUT 2 and it possible to visualize the incoming pulses divided by a value up to 9999.

The counter is available in two models: a) type KD401C: the pulses come from a free-voltage contact or from a static < NPN> based model. b) type KD401V: the pulses are voltage dependent (same value as the power line).The counter-programming is done through 3 front based keys. One more key “U” is available as reset.

The set-points are changeable even during the working cycle; instead the programming is possible only when the counter is reset to zero. It is possible also to lock the programming of the operative parameters (except the set-points). The SET/ CNT led points out if the counter is working (fixed on), if it is in programming mode (blinking) or it is not active (fixed off).

The settable counting frequencies are:

  • 1) 2 Hz
  • 2)10 Hz
  • 3) 40 Hz
  • 4) 125 Hz
  • 5) 1000 Hz

The output relay OUT1, with C1 value, turns ON at the end of the counting and with the parameter F1=1 or 2 it can be temporised through the parameter < r >.

The relay OUT2 works as a slow-down output and it is activated before OUT1. Its value must not be superior at C1 and it can be set as :

  • an absolute value (parameter F2=3 ) and it is visualised as “C2”.
  • relative value to OUT1 (parameter F2=4 ) and it is visualised as “C2d”.
