COUNT COMPENSATION
The pulse waveform status at the moment of power turned ON may cause the counter error by 1 count. Proceed according to
the following flow chart for compensating this error.

Turn the front DIP SW (SW2-4 or 1-4
*
) ON or OFF
respectively so that the Input Monitor LED (PL1 or
PL2
*
) is turned OFF.
The transmitter counts the first pulse sinking after its
rising since the power is turned on.
For voltage pulse, the first count is made when
waveform shifts from High to Low status, while for a
dry contact, it is made when the wave shifts from
OFF to ON.
