Input CH2/CH3 range (common)
Note (1) When the DIP switch is used to set the input ranges (pin 8 ON), the input
signal ranges must always be the same for Inputs CH0 and CH1 and for
Inputs CH2 and CH3. If it is necessary to set separate input signal ranges
for Inputs 0 to 3, use the CX-Integrator rather than the DIP switch to make
the settings.
(2) Do not set the DIP switches or pins other than as specified in the table
above.
