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.

DIP SWITCH 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
Choose an appropriate noise filter setting according to input
frequency. (The unit may not function within the described
accuracy level if no filter is used.)
‘High’ setting is used for input ranges ≤1 Hz.
‘Low’ setting is used for input ranges ≤1 kHz.
■
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
