 PULSE AMPLITUDE (rotary switch)  

(*) Factory setting

For RS-422 line driver pulse, this setting is invalid.
For voltage pulse input, select the pulse amplitude (V p-p) 
among the switch positions 0 through 6.  For open collector, 
mechanical contact or two-wire current pulse input, set the 
switch to 7.  DO NOT SET to 8 or 9.  The power supply to the 
unit must be turned off when changing the setting.

(*) Factory setting

For  RS-422  line  driver  pulse,  the  noise  filter  setting  is 
invalid.
SW2 is not used.  Turn all switches to OFF.
The  power  supply  to  the  unit  must  be  turned  off  when 
changing the setting.

• Input Type

• Noise Filter

‘High’ setting is used for the input frequency ≤10 Hz.
‘Low’ setting is used for the input frequency ≤500 Hz.
For mechanical contact input, ‘High’ setting is recommend-
ed to prevent typical chattering from counting.

 CAUTION FOR RS-422 LINE DRIVER PULSE

For RS-422 line driver pulse, the input amplitude, detect-
ing level and noise filter settings are all invalid.  However, 
in order to prevent errors in setting, set these switches as 
follows: 
    Input amplitude = 50 – 100 Vp-p (SW=0)
    Detecting level = 0V
    Noise filter = None
